Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of terminal, and in particular, to a display method, a system, a device and a storage medium. BACKGROUND

[0002] With the development of the Internet of Vehicles industry, vehicle-machine interconnection is becoming a low-cost and efficient Internet of Vehicles solution, among which the scheme of playing favorite music through a car audio is the most widely used. After a terminal device is connected to a car machine, in order to facilitate a user to operate each application on the terminal device through the car machine, a super desktop can be used to realize desktop application sharing. In the scenario of the super desktop, the car machine can display an application list of the terminal device and use the corresponding application.

[0003] However, in the existing scheme, the car machine can only open the application in the terminal device in a small window or full-screen mode through a virtual screen. In the case that the application is opened in a small window mode on the virtual screen of the car machine, if the user clicks a maximize operation control in the interface, the application full-screen display mode will be directly started. At this time, since the interface of some applications is not adapted to the special-shaped screen or the horizontal screen mode of the car machine, the display effect on the car machine after starting the application full-screen mode will be poor, which causes poor operation experience, poor display interface visual effect and less available application information of the user in the process of using the application, and may also cause problems such as disordered interface display position, unsuitable application control size and the like, thereby reducing the user experience. SUMMARY

[0004] Some embodiments of the present application provide a display method, which is described below from multiple aspects. The embodiments and advantages of the multiple aspects can be mutually referred to.

[0024] The first electronic device outputs second control data, and the second control data is used to control the second electronic device to display the third interface on the display screen.

[0025] According to the embodiment of the present application, when the vehicle machine displays the home page interface of the target application in the small window mode, if the user performs the operation of maximizing the small window interface to enter the full screen, the mobile phone can control the vehicle machine to pull up the full-screen layout of the parallel view mode based on the operation, so that the vehicle machine only displays the home page interface with an enlarged size in part of the display screen, which can increase the display area of the display screen for displaying the application interface, reduce the invalid operation area such as black screen or white screen, and make the vehicle machine display more information content without excessively stretching the application interface, thereby improving the display effect of the application on the vehicle machine.

[0031] According to the embodiments of the present application, when the car machine displays the home page interface of the target application after expansion of the size, if the user performs an operation of searching content or an operation of checking displayed content on the home page interface, the mobile phone can control the car machine to display two application interfaces of the same application in the form of split screen display within the application, and the two application interfaces can be different application interfaces. In this way, two application interfaces of the same application can be displayed on the car machine display screen at the same time, such as the home page interface and the music search interface of the music playing application.

[0036] The first electronic device outputs fourth control data, which is used to control the second electronic device to display the fifth interface on the screen.

[0037] According to the embodiments of this application, when the vehicle infotainment system displays two application interfaces of a target application in parallel view mode, if the user performs a minimize operation to exit full-screen mode on the parallel view interface, the mobile phone can control the vehicle infotainment system to exit the full-screen layout of parallel view mode based on this operation, so that the vehicle infotainment system displays one interface of the target application in a small window mode.

[0077] The illustrative embodiments of the present application include, but are not limited to, a display method, a system, a device, and a storage medium. The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present application.

[0078] The display method provided in this application can be applied to in-application split-screen display in a heterogeneous projection scenario. This scenario may include a first electronic device and a second electronic device establishing a connection. The first electronic device can use heterogeneous projection technology to project its screen to the second electronic device, thereby enabling the second electronic device to perform in-application split-screen display. For ease of explanation, this application uses a parallel view mode to represent the in-application split-screen function.

[0079] Specifically, heterogeneous projection means that the first electronic device and the second electronic device can display projection content asynchronously, or in other words, the display content of the first electronic device and the second electronic device can be different. For example, a terminal device (taking the first electronic device as an example in this application) can create a virtual screen and project the application interface of a music playback application onto the vehicle's infotainment system (taking the second electronic device as an example in this application), while the physical screen of the terminal device can display the main interface or the application interface of another application. That is, while the terminal device is displaying the main interface or the application interface of another application, the vehicle's infotainment system displays the application interface of the music playback application; that is, the terminal device and the vehicle's infotainment system display projection content asynchronously. Heterogeneous projection technology allows the terminal device to project the first application interface of a first application onto the vehicle's infotainment system display, while the terminal device displays the second application interface of a second application, facilitating user operation. The specific implementation principle of heterogeneous projection will not be elaborated in the embodiments of this application.

[0080] In one specific embodiment, the display method provided in this application can be applied to the use of applications on the terminal device via the vehicle-mounted system in a super desktop scenario after the vehicle-mounted system is connected to the terminal device, so that the applications can be displayed on the vehicle-mounted system in a parallel view mode.

[0081] Figure 1 a A schematic diagram illustrating a possible application scenario provided by one embodiment of this application is shown. For example... Figure 1 a As shown, the vehicle-mounted system 100 and the terminal device 200 ( Figure 1 a (Taking a mobile phone as an example of a terminal device) Specifically, the vehicle infotainment system 100 can open the Super Desktop (as an example of a preset mode) and automatically discover the connectable terminal device 200. Users can then connect by clicking on the connectable terminal device 200. The Super Desktop is a mode used to achieve desktop application sharing. After the vehicle infotainment system 100 opens the Super Desktop and successfully connects to the terminal device 200, the vehicle infotainment system 100 can display various applications installed on the terminal device 200 in the Super Desktop, enabling the sharing of desktop applications between the terminal device 200 and the vehicle infotainment system 100. Users can use various applications on the terminal device 200 through the vehicle infotainment system 100, and the vehicle infotainment system 100 can display the first and second application interfaces in a parallel view mode.

[0082] Figure 1 bA schematic diagram of the parallel visual field mode of the car machine 100 is shown. The parallel visual field mode of the car machine 100 in the present application, that is, two application interfaces of the same application are displayed in the first display window 110 and the second display window 120 of the car machine 100 respectively. For example, taking a music playing application as an example, the application interface in the music playing application can include a home page, a music playing interface, a music search interface, and the like. As shown in Figure 1 b the car machine can display the home page interface in the music playing application, for example, a "recommended music interface", in the first display window 110, and display the "music playing interface" of the music clicked by the user in the "recommended music interface" in the second display window 120. In addition, the second display window 120 can also display other interfaces in the music playing application, for example, a music search interface, a music list interface, or the same interface as the interface in the first display window 110, which is not limited herein.

[0083] It should be noted that Figure 1 a the application scenario of the super desktop shown is only an example, and the embodiments of the present application are not limited thereto.

[0084] In some embodiments, when the user uses an application through the super desktop of the car machine, the car machine can open the application in a small window or full screen mode on the virtual screen, which cannot achieve the parallel visual field mode when opening some applications on devices such as folding screen mobile phones or tablet computers. For example, with reference to the schematic diagram of the parallel visual field mode of the car machine 100 shown in FIG. 2, the car machine can open the music playing application in a small window mode in the first display window 110, and the music playing interface in the music playing application can include a maximize operation control 111. In the small window mode, the first display window 110 is only displayed in a part of the super desktop, and the remaining area still displays the application icons of various applications of the terminal device. Figure 2 Figure 2 A schematic diagram of the maximum full screen display process provided by some embodiments is shown. As shown in Figure 2 after the user starts the music playing application through the super desktop 210, the car machine can display the music playing interface of the music playing application in a small window mode in the first display window 220, and the music playing interface can include a maximize operation control 221. In the small window mode, the first display window 220 is only displayed in a part of the super desktop, and the remaining area still displays the application icons of various applications of the terminal device.

[0085] At this time, if the user wants to maximize the display interface, the maximize operation control 221 in the music playing interface can be clicked, for example, the user directly clicks the maximize operation control 221 by the finger. As shown in Figure 2 ​As shown, after the car machine receives the user's click operation on the maximum operation control 221, in response to the click operation, the music playing interface of the music playing application can be displayed in a full screen mode in the second display window 230. In the full screen mode, the second display window 230 fills the entire area of the super desktop, but the display position and size of the content part in the music playing interface do not change, or the content part in the music playing interface is stretched to fill the entire area of the super desktop. At this time, due to the fact that the interface of some applications is not adapted to the special-shaped screen or the horizontal screen mode of the car machine, after the application enters the full screen mode, only a small part of the display screen is used to display the application, and most of the area is a black screen or a white screen, etc. Invalid operation area, which makes the display effect on the car machine poor, causes poor operation experience, poor application display interface visual effect, and less available application information during the user's use of the application, and can also cause interface display position disorder, application control size is not suitable, etc. Make the user's use experience decline.

[0086] To solve the above problems, the display method provided by the embodiments of the present application is used to display the application in parallel view mode on the car machine to improve the user's use experience.

[0087] According to an embodiment of the present application, when the car machine (as an example of a second electronic device) displays the application interface in a small window mode in a super desktop mode (as an example of a preset mode), if the user performs a maximum operation to enter the full screen on the small window interface, the mobile phone can control the car machine to pull up the full screen layout of the parallel view mode, so that the car machine displays two application interfaces of the same application in the form of application internal split screen, and the two application interfaces can be different application interfaces. In this way, the car machine display screen can simultaneously display two application interfaces of the same application, such as simultaneously displaying the home page interface and the music playing interface of the music playing application. This display method can display more information content on the large screen of the car machine, and the display interface is more beautiful, the operation logic is more in line with the user's daily use, and the user's use experience on the car machine is improved.

[0088] According to an embodiment of the present application, since there is no user-operable switch control in the super desktop scene, the mobile phone can determine whether the target application opens the parallel view function according to the pre-configured whitelist, and only control the car machine to pull up the full screen layout of the parallel view mode for the application that opens the parallel view function. Moreover, the applications in the whitelist can be modified according to actual needs, and the applications with higher adaptation degree to the car machine display screen are added to the whitelist, which can ensure the correctness and beauty of the interface displayed in the parallel view mode, avoid the problems of interface display position disorder, application control size is not suitable, etc., so as to further ensure the user's use experience.

[0089] According to an embodiment of the present application, when the car machine displays the home page interface of the target application in the small window mode, if the user performs the operation of maximizing the small window interface to enter the full screen, the mobile phone can control the car machine to pull up the full screen layout of the parallel horizon mode, so that the car machine displays the home page interface in an enlarged size only in part of the display screen, the display area of the display screen for displaying the application interface is increased, the invalid operation area such as black screen or white screen is reduced, the car machine can display more information content, and the application interface is not excessively stretched, and the display effect of the application on the car machine is improved.

[0090] According to an embodiment of the present application, when the car machine displays the home page interface of the target application in the small window mode, if the user performs the operation of maximizing the small window interface to enter the full screen, the mobile phone can control the car machine to pull up the full screen layout of the parallel horizon mode, so that the car machine displays the home page interface in an enlarged size only in part of the display screen, the display area of the display screen for displaying the application interface is increased, the invalid operation area such as black screen or white screen is reduced, the car machine can display more information content, and the application interface is not excessively stretched, and the display effect of the application on the car machine is improved.

For an electronic device with one screen in a physical sense, it can include a main screen and a sub screen, wherein the main screen can be a first display window of the electronic device, and the sub screen can be a second display window of the electronic device.

[0092] In the above embodiment, the display mode of the second electronic device is split screen display in the vertical screen state of the second electronic device, and in other embodiments of the present application, it can also be split screen display in the horizontal screen state, i.e. split screen display up and down. Exemplarily, in the split screen display of the second electronic device in the vertical screen state, the first display window is on the left side of the display screen, and the second display window is on the right side of the display screen. In the split screen display of the second electronic device in the horizontal screen state, the first display window is above the display screen, and the second display window is below the display screen.

[0098] The processor 310 can also be provided with a memory for storing instructions and data. In some embodiments, the memory in the processor 310 is a cache memory. The memory can store instructions or data that have just been used or are used repeatedly by the processor 310. If the processor 310 needs to use the instructions or data again, it can be directly called from the memory. This avoids repeated access and reduces the waiting time of the processor 310, thereby improving the efficiency of the system.

[0099] In some embodiments, the processor 310 can obtain a maximization operation request message sent by the car machine in the super desktop mode, and control the car machine to pull up a full-screen layout of the parallel view mode based on the maximization request message, so that the car machine displays two application interfaces of the same application in the form of application intra-split screen display, and the two application interfaces can be different application interfaces. In this way, two application interfaces of the same application can be displayed on the car machine display screen at the same time, such as the home page interface and the music playing interface of the music playing application.

The electronic device 300 can also calculate the location of the touch based on the detection signal of the pressure sensor 380A. In some embodiments, touch operations applied to the same touch location but with different touch operation intensities can correspond to different operation instructions. For example, when a touch operation with a touch operation intensity less than a first pressure threshold is applied to a short message application icon, an instruction to view short messages is executed. When a touch operation with a touch operation intensity greater than or equal to the first pressure threshold is applied to the short message application icon, an instruction to create a new short message is executed.

[0150] It can be understood that the structure illustrated in the embodiments of the present application does not constitute a specific limitation on the electronic device 300. In other embodiments of the present application, the electronic device 300 can include more or fewer components than illustrated, or combine certain components, or split certain components, or different component arrangements. The illustrated components can be implemented in hardware, software, or a combination of software and hardware.

[0151] The specific flow of the display method provided by the embodiments of the present application is described in detail below.

[0152] The display method provided by the embodiments of the present application can be applied to a system including a first electronic device and a second electronic device, and the first electronic device and the second electronic device are communicatively connected. The first electronic device and the second electronic device can be electronic devices with a hardware structure as shown in Figure 3a and a software structure as shown in Figure 3b , Figure 3c or more or fewer components than illustrated, or combine certain components, or split certain components, or different component arrangements, and the like.

[0153] The following takes the first electronic device as a mobile phone, the second electronic device as a car machine, and a scenario of maximizing a display interface as an example to describe the display method provided by the embodiments of the present application in detail. A plurality of applications are installed in the mobile phone, some or all of which support a parallel horizon mode (i.e., support an application-in-screen function), and the car machine has a display screen.

[0154] Reference is made to the accompanying drawings Figure 4 , Figure 4 A flowchart of the display method provided by one of the embodiments of the present application is shown, which can include steps S401-S407.

[0155] S401: The mobile phone (as an example of the first electronic device) establishes a communication connection with the car machine (as an example of the second electronic device).

[0156] In the embodiments of the present application, the mobile phone and the car machine can establish a communication connection through a short-range wireless communication mode such as Bluetooth or WiFi. Specifically, the car machine can send a connection request to the mobile phone through Bluetooth or WiFi, and the mobile phone can establish a Bluetooth connection or a WiFi connection with the car machine in response to the connection request. The specific process of establishing a Bluetooth connection or a WiFi connection is not described herein again.

[0157] It should be noted that the above implementation of connecting through Bluetooth or WiFi is only an example, and in some embodiments, other wireless communication modes can also be used to establish a communication connection, or a wired communication mode can also be used to establish a communication connection, which is not limited in the embodiments of the present application.

[0158] In the embodiments of the present application, when the mobile phone and the car machine establish a communication connection, it can be determined whether the mobile phone supports a parallel horizon function first, and in the case that the mobile phone supports the parallel horizon function, a virtual container (MagicVirtualContainer) can be created based on a pre-configured application configuration file, and some parameters required for starting a subsequent application in a parallel horizon are initialized in the constructor of the virtual container.

[0159] Specifically, reference is made to the accompanying drawings Figure 5 , Figure 5 A flowchart of creating and releasing a virtual container provided by one of the embodiments of the present application is shown. As shown in FIG. 4, the method can include steps S401-S407. Figure 5As shown, when the mobile phone and the vehicle machine establish a communication connection in step S501, the intelligent travel module in the mobile phone application layer can determine whether the current mobile phone supports the parallel view function. Specifically, the intelligent travel module can read the pre-stored configuration item about whether the mobile phone supports the parallel view function, and determine whether the current mobile phone supports the parallel view function according to the data of the read configuration item. For example, it is assumed that the configuration item 1 indicates that the mobile phone supports the parallel view function, and it is assumed that the configuration item 0 indicates that the mobile phone does not support the parallel view function. Then, when the intelligent travel module reads the configuration item 1, it can be determined that the mobile phone supports the parallel view function; when the intelligent travel module reads the configuration item 0, it can be determined that the mobile phone does not support the parallel view function.

[0160] Specifically, if the parallel view function is supported, the intelligent travel module can call the parallel view service layer through the notifyMagicWindow() interface in step S502 to notify the parallel view service layer that the current connection state is connected. After receiving the interface call, the parallel view message management module in the parallel view service layer can send the current connection state to the parallel view management service module in step S503 by calling the handleMsgConnState() interface to process the current connection state sent by the intelligent travel module. In step S504, the parallel view management service module can save the record of the current connection state. The notifyMagicWindow() interface has a corresponding return value, and the type of the return value is boolean. The return value true represents that the parallel view service layer informs the intelligent travel module that the connection state is received successfully, and the return value false represents failure.

[0161] Since there is no user-operable switch control in the super desktop scene, in the embodiment of the application, whether the application opens the parallel view function can be controlled by the application white list. When the return value of the notifyMagicWindow() interface is true, the intelligent travel module can send the application configuration file of opening the parallel view function to the parallel view service layer by calling the sendConfigFiles() interface in step S505. The parallel view service layer can perform corresponding initialization operation according to the received application configuration file. The application configuration file is a pre-configured application white list, and each application in the white list opens the parallel view function. Each application not in the white list is regarded as not supporting the parallel view function. The application configuration file can be modified according to actual needs, for example, the application can be pulled into and out of the white list according to the degree of adaptation of the application to the vehicle machine display screen.

[0162] Specifically, after receiving the interface call, the Parallel Vision message management module can, in step S506, call the handleConfigFiles() interface to send the application configuration file to the Parallel Vision management service module for processing the application configuration file sent by the smart mobility module. For example, in step S507, the Parallel Vision management service module can send an initialization request to the Parallel Vision management module so that the Parallel Vision management module can create a corresponding virtual container (MagicVirtualContainer) based on the application configuration file. In the constructor of the virtual container, some parameters required for subsequent application startup with Parallel Vision will be initialized accordingly.

[0163] In one possible embodiment, such as Figure 5 As shown, when it is determined in step S508 that the communication connection between the mobile phone and the vehicle system is disconnected, the smart mobility module located in the mobile application layer can call the parallel vision service layer through the notifyMagicWindow() interface in step S509 to notify the parallel vision service layer that the current connection status is disconnected. After receiving the interface call, the parallel vision message management module in the parallel vision service layer can send the current connection status to the parallel vision management service module by calling the handleMsgConnState() interface in step S510 to process the current connection status sent by the smart mobility module. In step S511, the parallel vision management service module can send a release request to the parallel vision management module to make the parallel vision management module release the corresponding virtual container.

[0164] The process of creating and releasing virtual containers has been described in detail above. Now, let's return to step S402 to continue explaining the display method provided in the embodiments of this application.

[0165] S402: The vehicle system starts the super desktop mode (as an example of the preset mode). In the super desktop mode, the music application window interface is displayed (as an example of the first interface). The music application window interface includes a small window display window (as an example of the first display window). The small window display window is used to display the music playback interface of the "Music" application (as an example of the target application) (as an example of the first application interface).

[0166] In the embodiments of the present application, the interface size of the music application small window interface can be smaller than the size of the car machine display screen, that is, the first interface is small window display. The music application small window interface can include a small window display window, and the size of the small window display window can be the same as the size of the music application small window interface, that is, the small window display window fills the entire area of the music application small window interface. The size of the small window display window can also be smaller than the size of the music application small window interface, that is, the small window display window only occupies part of the area of the music application small window interface. The small window display window can be used to display the music playing interface of the "music" application.

[0167] In the embodiments of the present application, the first application interface can be a non-home page interface of the target application, for example, a detail interface corresponding to the home page of the target application. Alternatively, the first application interface can also be a home page interface of the target application. The target application can be any application installed in the mobile phone that supports the parallel view function, for example, a video playing application (such as "Tik Tok"), a news information application (such as "Today's Headlines"), and a music playing application (such as "Music") and the like third-party application.

[0168] It should be noted that in the embodiments of the present application, the "music" application is taken as an example of the target application, and the playing interface of a specific music, for example, the interface displaying the record cover or the lyrics, and the operation button, is taken as an example of the first application interface, but the present application is not limited thereto. In some embodiments, the first application interface can also be a music search interface, or can be a home page interface of the "music" application, and the like.

[0169] In the embodiments of the present application, after the car machine and the mobile phone establish a communication connection, the "Settings>Super Terminal>Super Desktop" can be entered on the mobile phone to turn on the switch of the super desktop. The mobile phone is close to the car machine, and the "All Applications>Super Desktop" is entered on the car machine. The super desktop automatically discovers the connectable mobile phone, and the connectable mobile phone is clicked to connect. After the connection is successful, the car machine starts the super desktop, and when the user clicks the "music" application icon in the super desktop, the car machine can open the "music" application in the small window mode and display the home page interface of the "music" application through the virtual screen. When the user performs the operation of browsing the information in the home page interface, for example, clicking to play a certain music, the car machine can display the corresponding music playing interface.

[0170] In actual application, after the car machine and the mobile phone establish a communication connection, the mobile phone can use the heterogeneous screen projection technology to realize screen projection to the car machine, so that the "music" application can be started on the virtual screen of the car machine in the small window mode. Specifically, the car machine can obtain the starting operation of the "music" application of the user in the super desktop mode, and send an application starting message of the "music" application to the mobile phone in response to the starting operation. The mobile phone obtains the application starting message sent by the car machine, and in response to the application starting message, can create a virtual screen corresponding to the "music" application, and generate a music application small window interface of the "music" application homepage interface of the virtual screen based on the screen size of the virtual screen. The mobile phone can output the control data (as an example of the fifth control data) of the music application small window interface to the car machine, which can be used to control the car machine to display the homepage interface of the "music" application on the display screen.

[0171] Specifically, the car machine can also obtain the operation of the user playing a certain music, and send a music playing operation message of the "music" application to the mobile phone in response to the operation. The mobile phone obtains the music playing operation message sent by the car machine, and in response to the music playing operation message, can generate a music application small window interface of the "music" application music playing interface of the virtual screen based on the screen size of the virtual screen of the "music" application. The mobile phone can output the control data (as an example of the fifth control data) of the music application small window interface to the car machine, which can be used to control the car machine to display the music playing interface of the "music" application on the display screen.

[0172] Exemplarily, Figure 6a A schematic diagram of starting an application in a small window mode provided by an embodiment of the present application is shown. As shown in Figure 6a The super desktop 600 of the car machine can display the application icons of each application installed in the mobile phone. When the user clicks the "music" application icon 601 in the super desktop 600, the car machine can open the "music" application and display the homepage interface 610 of the "music" application in response to the click operation of the user on the application icon 601. The homepage interface 610 can include a play control 602 for playing music, and when the user clicks the play control 602, the car machine can display the music playing interface 620 of the "music" application in response to the click operation of the user on the play control 602.

[0173] In one possible embodiment, after the car machine starts the super desktop, when the user clicks the "music" application icon in the super desktop, the car machine can also directly open the "music" application in the small window mode and display the music playing interface of the "music" application through the virtual screen. The music playing interface can be, for example, the playing interface of the music being played when the user last closed the "music" application, and the like, which is not limited in the embodiment of the present application.

[0174] Specifically, in Super Desktop mode, the vehicle's infotainment system can receive the user's launch operation for the "Music" application and, in response, send an application launch message for the "Music" application to the mobile phone. The mobile phone receives the application launch message from the vehicle's infotainment system and, in response, can create a virtual screen corresponding to the "Music" application. Based on the screen size of the virtual screen, it directly generates a small window interface for displaying the music playback interface of the "Music" application on the virtual screen. The mobile phone can output control data for this music application window interface to the vehicle's infotainment system (as an example of the fifth control data). This control data can be used to control the vehicle's infotainment system to display the music playback interface of the "Music" application on the screen.

[0175] In this embodiment of the application, when the mobile phone receives the application launch message for the "Music" application sent by the vehicle system in the super desktop mode, it can first create a virtual screen corresponding to the "Music" application, and then realize the projection of the virtual screen to the vehicle system, so that the display screen of the vehicle system can display the content on the virtual screen, while the display screen of the mobile phone does not display the content on the virtual screen.

[0176] Specifically, refer to the appendix of the instruction manual. Figure 7 , Figure 7 A flowchart illustrating the creation and deletion of a virtual screen according to an embodiment of this application is shown. Figure 7 As shown, when creating the virtual screen corresponding to the "Music" application, in step S701, the smart travel module located in the mobile application layer can call the Parallel Vision service layer through the updateAppMagicWinStatusIn MultiDevice(intreason,int targetDisplayId,int targetWidth,int targetHeight) interface to notify the Parallel Vision service layer of the identifier (DisplayId) and screen size information of the virtual screen corresponding to the "Music" application. Here, reason indicates the operation that the "Music" application needs to perform next (e.g., entering or exiting full-screen mode), targetDisplayId indicates which virtual screen the "Music" application needs to launch on, and targetWidth and targetHeight represent the specific screen size of the virtual screen (including width and height parameters).

[0177] After the parallel view message management module in the parallel view service layer receives the interface call, the virtual screen information (including the identifier and screen size information of the virtual screen) in the calling parameters of the updateAppMagicWinStatusInMultiDevice(int reason, int targetDisplayId, int targetWidth, int targetHeight) interface can be sent to the parallel view management service module in step S702. The virtual container (MagicVirtualContainer) created by the parallel view management module can be initialized according to the virtual screen information, and generate the home page interface or the music playing interface of the "music" application displayed on the virtual screen based on the screen size of the virtual screen. It should be noted that the screen size of the virtual screen supported in the embodiments of the present application satisfies that the height is greater than the width in the single window mode of the parallel view mode.

[0178] Specifically, in step S703, the virtual container can obtain the identifier (attachDisplayId) of the virtual screen. In step S704, the virtual container can update the metrics (updateDisplayMetrics) of the virtual screen according to the screen size information of the virtual screen. In step S705, the virtual container can register an event listener (registerEventListener) to listen to the creation of the virtual screen event, and in step S706, generate the interface of the home page interface of the "music" application or the interface of the music playing interface of the "music" application displayed on the virtual screen by calling the interface generation function createMwUi(targetDisplayId, container).

[0179] In one possible embodiment, when the user closes the "music" application, the car machine can send an application closing message to the mobile phone in response to the user's closing operation of the "music" application. After the mobile phone receives the application closing message sent by the car machine, the "music" application can be closed and the virtual screen corresponding to the "music" application can be deleted. As shown in FIG. 8, when the user closes the "music" application, the car machine can send an application closing message to the mobile phone in step S801. After the mobile phone receives the application closing message sent by the car machine, the "music" application can be closed and the virtual screen corresponding to the "music" application can be deleted in step S802. Figure 7As shown, in deleting the virtual screen corresponding to the "music" application, in step S707, the intelligent travel module located in the mobile application layer can call the interface updateAppMagicWinStatusIn MultiDevice(int reason, int targetDisplayId) to the parallel visual service layer to notify the parallel visual service layer of the identifier of the virtual screen corresponding to the "music" application. After receiving the interface call, the parallel visual message management module in the parallel visual service layer can issue the identifier of the virtual screen in the calling parameters of the interface updateAppMagicWinStatusIn MultiDevice(int reason, int targetDisplayId, int targetWidth, int targetHeight) to the parallel visual management service module in step S708. The virtual container created by the parallel visual management module can delete the corresponding virtual screen according to the identifier of the virtual screen.

[0180] Specifically, in step S709, the virtual container can adjust the camera in the mobile phone to a state without the influence of the parallel visual by calling the function updateCameraRotation(-1). In step S710, the virtual container can delete the virtual screen corresponding to the "music" application by calling the function setVirtualDisplayId(INVALID_DISPLAY).

[0181] The above details the process of creating and deleting a virtual screen. The following returns to step S403 to continue to describe the display method provided in the application embodiment.

[0182] S403: The car machine acquires a maximization operation (as an example of a first operation) on the music application small window interface, and sends a maximization operation request message (as an example of a first operation request message) to the mobile phone in response to the maximization operation.

[0183] In the application embodiment, when the user performs a maximization operation on the music application small window interface, the car machine can generate a maximization operation request message in response to the maximization operation and send it to the mobile phone. The maximization operation can be used to maximize the music application small window interface and make it enter a full-screen state. The maximization operation on the music application small window interface can be a sliding, clicking or dragging operation of the user's finger on the music application small window interface, or a sliding, clicking or dragging operation of the user's finger on the maximization operation control in the music application small window interface. The finger can be a single finger or multiple fingers, which is not limited here.

[0184] Specifically, the car machine can be integrated with a car machine out terminal module. When the car machine is connected to the mobile phone and is in the super desktop mode, the user starts the "music" application and clicks the maximize operation control, the car machine out terminal module can send a maximize operation request message to the smart travel module in the mobile phone to inform the user's operation, and then pull up the application full screen through the smart travel module.

[0185] S404: The mobile phone obtains the maximize operation request message sent by the car machine.

[0186] In the embodiment of the application, the mobile phone and the car machine can realize data interaction through a pre-established communication connection. For example, the car machine can send a maximize operation request message to the mobile phone through a Bluetooth connection or a WiFi connection. Specifically, the car machine can send a maximize operation request message to the smart travel module in the mobile phone through a Bluetooth connection or a WiFi connection, and the smart travel module can receive the maximize operation request message sent by the car machine.

[0187] S405: The mobile phone determines the screen size of the virtual screen corresponding to the "music" application in response to the maximize operation request message.

[0188] In the embodiment of the application, the car machine realizes parallel view display, which is different from the mobile phone supporting parallel view. The super desktop is a virtual screen scenario. When the super desktop starts an application, the mobile phone and the car machine are in a heterogeneous screen projection scenario. At this time, the mobile phone uses a heterogeneous screen projection technology to realize screen projection to the car machine, so as to display the music application window interface to the virtual screen of the car machine. Therefore, after the mobile phone obtains the maximize operation request message, the mobile phone can first determine the screen size of the car machine, and take the screen size of the car machine as the screen size of the virtual screen corresponding to the "music" application after maximization. The screen size of the car machine can be obtained from the car machine side, for example, the car machine can carry the screen size of the car machine in the maximize operation request message sent by the car machine. The screen size of the car machine can also be saved in a database in advance. After the mobile phone obtains the maximize operation request message, the mobile phone can directly obtain the screen size of the car machine from the database. The embodiment of the application does not make specific limitation on this.

[0189] In the embodiment of the application, after the smart travel module receives the maximize operation request message sent by the car machine, the smart travel module can first call the resizeDisplay() interface to call the screen projection service module. The screen projection service module can perform size adjustment (Resize) processing on the virtual screen corresponding to the "music" application according to the received screen size (including width and height parameters). After the size adjustment is successful, the window is displayed as full screen size.

[0190] S406: The mobile phone starts the parallel visual field mode, and generates a music application split-screen interface (as an example of the second interface) of the virtual screen based on the screen size of the virtual screen in the parallel visual field mode. The music application split-screen interface can include a left display window (as an example of the second display window) and a right display window (as an example of the third display window) displayed in split screen, and the left display window and the right display window are respectively used to display a music playing interface and a home page interface (as an example of the second application interface) of the "music" application.

[0191] In the embodiments of the present application, the interface size of the music application split-screen interface can be the same as the size of the display screen of the car machine, that is, the second interface is full-screen display. The sizes of the left display window and the right display window of the music application split-screen interface can be the same or different. The left display window and the right display window can be split up and down or split left and right. In the embodiments of the present application, the left and right split is taken as an example for description. The left display window and the right display window can occupy all or part of the area of the music application split-screen interface. The position and size of the left display window and the right display window are not specifically limited in the embodiments of the present application. Preferably, the height of the single window in the parallel visual field in the present application can be greater than the width, that is, the height of the left display window and the right display window is greater than the width.

[0192] It should be noted that the above embodiment of taking the home page interface as the second application interface is only an example. In some embodiments, the second application interface can also be other interfaces of the "music" application. The second application interface can be the same as or different from the first application interface, and the embodiments of the present application do not specifically limit this. For example, the second application interface can also be the same interface as the first application interface, that is, the music playing interface of the "music" application, or can also be a music search interface, etc.

[0193] In an embodiment of the present application, after the screen size of the virtual screen is adjusted by the screen projection service module, the intelligent travel module can call the parallel visual service layer through the updateAppMagicWinStatusInMultiDevice(int reason, int targetDisplayId, int targetWidth, int targetHeight) interface to notify the parallel visual service layer of the identifier (DisplayId) of the virtual screen corresponding to the "music" application and the adjusted screen size information. After receiving the interface call, the parallel visual message management module in the parallel visual service layer can distribute the virtual screen information (including the identifier of the virtual screen and the adjusted screen size information) in the call parameters to the parallel visual management service module. The virtual container created by the parallel visual management module can start the parallel visual mode according to the virtual screen information, and generate the virtual screen while displaying the music application split screen interface of the music playing interface and the home page interface of the "music" application in the parallel visual mode based on the adjusted screen size of the virtual screen. Specifically, the virtual container can generate the music application split screen interface by calling the interface generation function createMwUi(targetDisplayId, container) when it listens to the display interface of the generated virtual screen.

[0194] In actual application, in the virtual screen scenario, the application framework layer of the mobile phone will newly create a separate task (Task) for this scenario. Among them, a layer of root task (RootTask) is used to identify the vehicle scene (the vehicle scene is a virtual screen scenario, which is different from the physical screen scenario of the mobile phone) for customized processing, including window display level, window visibility, window display mode and the like. A layer of Task of the application itself is used to implement the management of activities (activity).

[0195] Exemplarily, Figure 6b A schematic diagram of switching from the small window mode to the parallel visual mode is shown. As shown in Figure 6b The small window display window of the music application small window interface in the super desktop 600 displays the music playing interface 620 of the "music" application. The music application small window interface can also include a maximize operation control 603. When the user clicks the maximize operation control 603, the vehicle machine can generate and send a maximize operation request message to the mobile phone in response to the click operation of the user on the maximize operation control 603. The mobile phone can determine the screen size of the virtual screen corresponding to the "music" application and start the parallel visual mode in response to the maximize operation request message, and generate the music application split screen interface of the virtual screen based on the screen size of the virtual screen in the parallel visual mode. The left display window of the music application split screen interface displays the home page interface 610 of the "music" application, and the right display window displays the music playing interface 620 of the "music" application.

[0196] In a possible implementation, the phone starts the parallel view mode, and generating the music application split-screen interface of the virtual screen in the parallel view mode based on the screen size of the virtual screen can include: the phone determining whether the "music" application starts the parallel view function; if the "music" application starts the parallel view function, the phone starts the parallel view mode, and generates the music application split-screen interface of the virtual screen in the parallel view mode based on the screen size of the virtual screen.

[0197] In the embodiments of the present application, only part of the applications in the phone support the parallel view mode display, and only part of the applications can be well adapted to the car machine parallel view mode display. Therefore, before starting the parallel view mode, the phone can first determine whether the "music" application starts the parallel view function. In the case of starting, the step S405 of starting the parallel view mode and generating the music application split-screen interface of the virtual screen is executed; in the case of not starting, the music playing interface of the "music" application is displayed in the ordinary full-screen mode. In the ordinary full-screen mode, the display window of the music playing interface fills the entire area of the super desktop, but the display position and size of the content part in the music playing interface do not change, or the content part in the music playing interface is also stretched to fill the entire area of the super desktop.

[0198] Exemplarily, Figure 6c A schematic diagram of switching from the small window mode to the ordinary full-screen mode is shown, which is provided by an embodiment of the present application. As shown in Figure 6c As shown, after the user starts the "video" application in the super desktop 600, the application in the small window can be replaced, at this time, the small window display window of the video application small window interface (as another example of the first interface) in the super desktop 600 can display the video playing interface 630 of the "video" application, and the video application small window interface can also include the maximize operation control 604. When the user clicks the maximize operation control 604, the car machine can generate and send a maximize operation request message to the phone in response to the click operation of the user on the maximize operation control 604. The phone can determine the screen size of the virtual screen corresponding to the "video" application in response to the maximize operation request message. The phone can also determine that the "video" application does not start the parallel view function, and therefore the phone displays the video playing interface 630 of the "video" application in the ordinary full-screen mode. In the ordinary full-screen mode, the display window of the video playing interface 630 fills the entire area of the super desktop 600, but the display position and size of the video content in the video playing interface 630 do not change.

[0199] Specifically, the phone determining whether the "music" application opens the parallel view function can include: the phone judging whether the "music" application is recorded in the pre-configured whitelist; if yes, determining that the "music" application opens the parallel view function; if not, determining that the "music" application does not open the parallel view function.

[0200] In the embodiments of the present application, the application in the whitelist can be supported to display in the parallel view mode when performing the maximum operation to enter the application full screen by pre-configuring the whitelist. The whitelist can be modified according to actual needs, for example, the application can be pulled into and out of the whitelist according to the adaptation degree of the application to the car machine display screen. The detailed content of the whitelist is not described herein.

[0201] It should be noted that the music playing interface is taken as an example of the first application interface for description in the embodiments of the present application, but in actual application, the first application interface can also be other interfaces of the "music" application.

[0202] In one possible embodiment, since some applications cannot directly enter the parallel view mode and display two application interfaces from the home page interface when the user performs the maximum operation to enter the full screen. Therefore, for this type of application, the in-application split screen display is only performed when the first application interface is a non-home page interface of the application; and the split screen display is not performed when the first application interface is a home page interface of the application. The embodiments of the present application are described below by assuming that the "music" application is this type of application that cannot directly enter the parallel view mode and display two application interfaces from the home page interface.

[0203] Specifically, if the "music" application opens the parallel view function, the phone starts the parallel view mode and generates a music application split screen interface of the virtual screen based on the screen size of the virtual screen in the parallel view mode, which can include: if the "music" application opens the parallel view function, the phone determines whether the first application interface is a non-home page interface of the "music" application; if the first application interface is a non-home page interface of the "music" application, the phone starts the parallel view mode and generates a music application split screen interface of the virtual screen based on the screen size of the virtual screen in the parallel view mode. Moreover, the first application interface and the second application interface displayed in the music application split screen interface are different application interfaces. For example, the first application interface can be a non-home page interface of the "music" application, and the second application interface can be a home page interface of the "music" application. Specifically, the case that the first application interface is a home page interface of the "music" application will be described in detail later.

[0204] S407: The phone outputs the control data of the music application split screen interface (as an example of the first control data) to the car machine, and the control data of the music application split screen interface is used to control the car machine to display the music application split screen interface on the display screen.

[0205] In the embodiment of the present application, the mobile phone can use the heterogeneous screen projection technology to realize screen projection to the car machine. In the screen projection process, the control data of the music application split screen interface can be output to the car machine to project the music application split screen interface of the virtual screen to the display screen of the car machine for display. The detailed process of screen projection to the car machine is not described herein.

[0206] The case that the first application interface is the home page interface of the "music" application is described in detail below.

[0207] Reference is made to the accompanying drawings Figure 8 , Figure 8 A flowchart of a display method provided by another embodiment of the present application is shown, which can include steps S801-S807.

[0208] S801: The mobile phone (as an example of the first electronic device) establishes a communication connection with the car machine (as an example of the second electronic device).

[0209] S802: The car machine starts the super desktop mode (as an example of the preset mode), and displays the music application window interface (as an example of the first interface) in the super desktop mode. The music application window interface includes a window display window (as an example of the first display window), which is used to display the home page interface (as an example of the first application interface) of the "music" application (as an example of the target application).

[0210] In the embodiment of the present application, the window display window of the music application window interface can be used to display the home page interface of the "music" application, i.e., the first application interface is the home page interface of the target application.

[0211] In the embodiment of the present application, after the car machine is successfully connected with the mobile phone, the car machine starts the super desktop. When the user clicks the "music" application icon in the super desktop, the car machine can open the "music" application in the window mode and display the home page interface of the "music" application by the virtual screen.

[0212] In actual application, after the car machine and the mobile phone establish a communication connection, the mobile phone can use the heterogeneous screen projection technology to realize screen projection to the car machine, so that the "music" application can be started in a small window mode to the virtual screen of the car machine. Specifically, the car machine can obtain the start operation of the "music" application in the super desktop mode, and send an application start message of the "music" application to the mobile phone in response to the start operation. The mobile phone obtains the application start message sent by the car machine, and in response to the application start message, can create a virtual screen corresponding to the "music" application, and generate a music application small window interface of the "music" application based on the screen size of the virtual screen. The mobile phone can output the control data (as an example of the fifth control data) of the music application small window interface to the car machine, which can be used to control the car machine to display the home page interface of the "music" application on the display screen.

[0213] S803: The car machine obtains a maximization operation (as an example of the first operation) for the music application small window interface, and sends a maximization operation request message (as an example of the first operation request message) to the mobile phone in response to the maximization operation.

[0214] S804: The mobile phone obtains the maximization operation request message sent by the car machine.

[0215] S805: The mobile phone determines the screen size of the virtual screen corresponding to the "music" application in response to the maximization operation request message.

[0216] S806: The mobile phone starts the parallel view mode, and generates a music application large window interface (as an example of the third interface) of the virtual screen based on the screen size of the virtual screen in the parallel view mode. The music application large window interface can include a large window display window (as an example of the fourth display window), and the size of the large window display window is larger than that of the small window display window in the music application small window interface. The large window display window is used to display the home page interface of the "music" application with an enlarged size.

[0217] In the embodiment of the application, when the first application interface is the home page interface of the "music" application, starting the parallel view mode by the mobile phone will not perform split screen display, but only enlarge the display size of the home page interface.

[0218] Specifically, in the case that the first application interface is the homepage interface of the "music" application, after the phone starts the parallel visual field mode, the phone can generate the music application large window interface based on the screen size of the virtual screen in the parallel visual field mode. The interface size of the music application large window interface can be the same as the size of the display screen of the car machine, that is, the third interface is full screen display. The music application large window interface can include a large window display window, and the large window display window can be located in only a part of the music application large window interface, and is preferably located in the middle region of the music application large window interface. The application embodiments do not specifically limit the position and size of the large window display window in the music application large window interface. Preferably, the height of the single window in the parallel visual field in the application can be greater than the width, that is, the height of the large window display window is greater than the width. The area of the music application large window interface except the large window display window can be displayed as blank.

[0219] In one possible embodiment, before starting the parallel visual field mode, the phone can first determine whether the "music" application opens the parallel visual field function. In the case of determining to open the parallel visual field function, it can be determined whether the first application interface is the homepage interface of the "music" application. If the first application interface is the homepage interface of the "music" application, the phone starts the parallel visual field mode and generates the music application large window interface of the virtual screen based on the screen size of the virtual screen in the parallel visual field mode.

[0220] It should be noted that the specific generation method of the third interface is similar to the generation method of the second interface, and the specific content provided by the embodiments shown in Figures 4 to 7 will not be repeated here.

[0221] Exemplarily, Figure 9a Fig. 6 shows a schematic diagram of switching from the small window mode to the parallel visual field mode provided by another embodiment of the application. As shown in Figure 9a Fig. 6, the small window display window of the music application small window interface in the super desktop 900 displays the homepage interface 910 of the "music" application, and the music application small window interface can further include a maximize operation control 901. When the user clicks the maximize operation control 901, the car machine can generate and send a maximize operation request message to the phone in response to the clicking operation of the user on the maximize operation control 901. The phone can determine the screen size of the virtual screen corresponding to the "music" application and start the parallel visual field mode in response to the maximize operation request message, and generate the music application large window interface of the virtual screen based on the screen size of the virtual screen in the parallel visual field mode. The large window display window of the music application large window interface only occupies the middle part of the music application large window interface, and displays the homepage interface 910 of the "music" application in an enlarged size.

[0222] S807: The mobile phone outputs control data (as an example of the second control data) of the music application large window interface to the vehicle machine, and the control data of the music application large window interface is used to control the vehicle machine to display the music application large window interface on the display screen.

[0223] In one possible embodiment, the reference is made to the description of the accompanying drawings Figure 10 The method can further include steps S808-S810.

[0224] S808: The mobile phone acquires a music search operation (as an example of the second operation) based on the home page interface.

[0225] In the embodiments of the present application, the second operation can be an operation for browsing the content in the home page interface of the "music" application, for example, can be a search operation for searching the content in the home page interface of the "music" application, or can be a review operation for reviewing the display content in the home page interface of the "music" application, etc., and the type of the operation is not specifically limited in the embodiments of the present application. The embodiments of the present application take the second operation as the music search operation as an example for description, but the present application is not limited thereto, and in some embodiments, the second operation can also be a music playing operation, etc.

[0226] In the embodiments of the present application, when the user performs the music search operation for searching the content in the home page interface of the "music" application, for example, the user performs a click operation on the music search control in the home page interface of the "music" application, the vehicle machine can send the position information of the click operation to the mobile phone, and the mobile phone can determine the corresponding position information in the virtual screen corresponding to the "music" application according to the position information of the click operation, and then determine that the user performs the music search operation for searching the content in the home page interface of the "music" application. Wherein, the music search operation can be used to search the interested music in the home page interface of the "music" application.

[0227] It should be noted that the above-mentioned way of searching the content by performing the click operation on the music search control is only an example, and the present application does not specifically limit it, and in some possible embodiments, the music search operation for searching the content in the home page interface of the "music" application can also be the sliding, clicking or dragging operation of the user's finger on the home page interface of the "music" application, or can be the sliding or dragging operation of the user's finger on the music search control in the home page interface of the "music" application, and the finger can be a single finger or multiple fingers, which is not limited herein.

[0228] In one possible embodiment, the mobile phone can also acquire the voice of the user for searching the content in the home page interface of the "music" application, analyze the voice, and thus determine that the user performs the music search operation for searching the content in the home page interface of the "music" application.

[0229] S809: The phone generates a music application split-screen interface of the virtual screen (as an example of the fourth interface) based on the screen size of the virtual screen in the parallel visual field mode in response to the music search operation. The music application split-screen interface can include a left display window (as an example of the fifth display window) and a right display window (as an example of the sixth display window) displayed in split screen. The left display window and the right display window are respectively used to display a music search interface (as an example of the third application interface) and a home page interface of the "music" application.

[0230] It should be noted that the interface size of the music application split-screen interface can be the same as the size of the display screen of the car machine, that is, the fourth interface is full-screen display. The size of the left display window and the right display window of the music application split-screen interface can be the same or different. The left display window and the right display window can be split up and down or split left and right. In the embodiments of the present application, the left and right split is taken as an example for description. The left display window and the right display window can occupy all or part of the area of the music application split-screen interface. The position and size of the left display window and the right display window are not specifically limited in the embodiments of the present application. Preferably, the height of the single window in the parallel visual field in the present application can be greater than the width, that is, the height of the left display window and the right display window is greater than the width.

[0231] In the embodiments of the present application, the third application interface can be a result interface corresponding to the second operation. In the case where the second operation is a search operation of searching content in the home page interface of the "music" application, the third application interface can be a music search interface of the "music" application.

[0232] It should be noted that the above embodiment of taking the music search interface as the third application interface is only an example. In some embodiments, the third application interface can also be other interfaces of the "music" application according to different user operations, which is not specifically limited in the embodiments of the present application. For example, in the case where the second operation is a review operation of reviewing the displayed content in the home page interface of the "music" application, the third application interface can be a content detail interface of the "music" application. For example, when the user performs a review operation on a certain music ranking in the home page interface of the "music" application, the third application interface can be a list detail interface of the "music" application. In the case where the second operation is a play operation of playing music in the home page interface of the "music" application, the third application interface can be a music playing interface of the "music" application.

[0233] Specifically, after the phone obtains the music search operation based on the home page interface, since the display interface has been maximized, it is not necessary to adjust the screen size of the virtual screen, but the music application split-screen interface of the virtual screen can be directly generated based on the screen size of the virtual screen.

[0234] It should be noted that the specific generation method of the fourth interface is similar to the generation method of the second interface, and the specific content can be referred to Figures 4 to 7 The specific content provided by the embodiment shown in the embodiment is not described here.

[0235] Exemplarily, Figure 9b A schematic diagram of a user performing a music search operation process provided by an embodiment of the present application is shown. As shown in Figure 9b As shown, the large window display window of the music application large window interface in the super desktop displays the home page interface 910 of the "music" application after the size is enlarged. The music application large window interface can also include a music search control 902. When the user clicks the music search control 902, the car machine can send the position information of the user's click to the mobile phone, and the mobile phone can determine the corresponding position information in the virtual screen corresponding to the "music" application according to the position information, and then determine that the user performs the click operation on the music search control 902, that is, the mobile phone can obtain the music search operation performed by the user. The mobile phone can generate a music application split screen interface of the virtual screen based on the screen size of the virtual screen in the parallel visual field mode in response to the music search operation performed by the user. The left display window of the music application split screen interface displays the home page interface 910 of the "music" application, and the right display window displays the music search interface 920 of the "music" application.

[0236] S810: The mobile phone outputs the control data (as an example of the third control data) of the music application split screen interface to the car machine, and the control data of the music application split screen interface is used to control the car machine to display the music application split screen interface on the display screen.

[0237] It should be noted that the specific content in steps S801 to S807 and steps S808 to S810 in the embodiment of the present application can refer to the related content in steps S401 to S407 in the embodiment shown in Figure 4 The specific content in steps S401 to S407 in the embodiment shown in the embodiment of the present application is not described here.

[0238] The display method provided by the embodiment of the present application will be described in detail below taking the scenario of the reduced display interface as an example.

[0239] Reference is made to the drawings in the specification Figure 11 , Figure 11 A flowchart of a display method provided by another embodiment of the present application is shown, which can include steps S1101-S1107.

[0240] S1101: The mobile phone (as an example of the first electronic device) and the car machine (as an example of the second electronic device) establish a communication connection.

[0241] S1102: The car machine starts the super desktop mode (as an example of a preset mode), and displays a music application split-screen interface (as an example of a second interface or a fourth interface) in the super desktop mode.

[0242] S1103: The car machine acquires a zoom-out operation (as an example of a third operation) for the music application split-screen interface, and sends a zoom-out operation request message (as an example of a third operation request message) to the mobile phone in response to the zoom-out operation.

[0243] In the embodiments of the present application, when the user performs a zoom-out operation for the music application split-screen interface, the car machine can generate a zoom-out operation request message in response to the zoom-out operation and send it to the mobile phone. The zoom-out operation can be used to zoom out the music application split-screen interface and exit the full-screen state. The zoom-out operation for the music application split-screen interface can be a sliding, clicking, or dragging operation of the user's finger on the music application split-screen interface, or a sliding, clicking, or dragging operation of the user's finger on a zoom-out operation control in the music application split-screen interface. The finger can be a single finger or multiple fingers, which is not limited herein.

[0244] Specifically, when the car machine is connected to the mobile phone and is in the super desktop mode, the user clicks a zoom-out operation control in the interface displayed in the parallel view mode, the car machine out-end module in the car machine can send a zoom-out operation request message to the smart travel module in the mobile phone to inform the user's operation, and then exit the application full screen through the smart travel module.

[0245] S1104: The mobile phone acquires the zoom-out operation request message sent by the car machine.

[0246] S1105: The mobile phone adjusts the screen size of the virtual screen corresponding to the "music" application in response to the zoom-out operation request message.

[0247] In the embodiments of the present application, after the mobile phone acquires the zoom-out operation request message, it can first adjust the screen size of the virtual screen to a preset size as the screen size of the zoomed-out virtual screen corresponding to the "music" application. The preset size can be set according to actual needs, for example, it can be set to be the same as the initial screen size of the virtual screen when the "music" application is started, which is not limited in the embodiments of the present application.

[0248] In the embodiments of the present application, after the smart travel module receives the zoom-out operation request message sent by the car machine, it can first call the resizeDisplay() interface to call the screen projection service module. The screen projection service module can perform Resize processing on the virtual screen corresponding to the "music" application according to the received screen size (including width and height parameters). After the Resize is successful, the full-screen state is exited.

[0249] S1106: The mobile phone exits the parallel visual field mode, and generates a music application sub-window interface (as an example of the fifth interface) of the virtual screen based on the adjusted screen size of the virtual screen. The music application sub-window interface can include a sub-window display window (as an example of the seventh display window), which can be used to display a music playing interface (as an example of the first application interface) or a music search interface (as an example of the third application interface) of the "music" application.

[0250] In the embodiments of the present application, the interface size of the music application sub-window interface can be smaller than the size of the car machine display screen, that is, the fifth interface is a sub-window display. The size of the sub-window display window can be the same as the size of the music application sub-window interface, that is, the sub-window display window fills the entire area of the music application sub-window interface. The size of the sub-window display window can also be different from the size of the music application sub-window interface, that is, the sub-window display window can only be located in part of the music application sub-window interface. The embodiments of the present application do not specifically limit the position and size of the sub-window display window in the music application sub-window interface.

[0251] Specifically, in the case that the zoom-out operation request message is a zoom-out operation request message for the second interface, the sub-window display window of the music application sub-window interface can be used to display the music playing interface of the "music" application; in the case that the zoom-out operation request message is a zoom-out operation request message for the fourth interface, the sub-window display window of the music application sub-window interface can be used to display the music search interface of the "music" application.

[0252] Unlike the parallel visual field mode display of the mobile phone, when the mobile phone displays in the parallel visual field mode, there is no zoom-out full-screen button in the interface, and there is no scene of returning to a single interface from the parallel visual field. In the embodiments of the present application, the zoom-out full-screen button can be displayed in the display interface, and the user can perform the zoom-out full-screen operation on the display interface based on the zoom-out full-screen button.

[0253] Specifically, after the phone obtains the zoom-out operation request message, the smart travel module can call the parallel view service layer through the updateAppMagicWinStatusInMultiDevice(int reason, int targetDisplayId, int targetWidth, int targetHeight) interface. Unlike the maximum operation, the corresponding operation (reason) REASON_EXIT_FULLSCREEN is added for the zoom-out full-screen scene, which is used to indicate the exit of the parallel view mode. When the parallel view service layer receives this parameter, it can determine whether the virtual screen corresponding to the "music" application is in the parallel view mode. If so, it will call the moveFocusTaskToQuitMagicInVirtual method function to obtain the task on the corresponding virtual screen and make it exit the parallel view mode.

[0254] Specifically, after the phone exits the parallel view mode, the music application small window interface of the virtual screen can be generated based on the adjusted screen size of the virtual screen. The detailed process of generating the music application small window interface will not be described here.

[0255] S1107: The phone outputs the control data of the music application small window interface (as an example of the fourth control data) to the car machine, and the control data of the music application small window interface is used to control the car machine to display the music application small window interface on the display screen.

[0256] It should be noted that the specific content of steps S1101 to S1107 in the embodiments of the present application can refer to the related content in steps S401 to S407 in the embodiments shown in Figure 4 , and the related content in steps S801 to S810 in the embodiments shown in Figures 8 to 10 , which will not be described here.

[0257] The display method provided by another embodiment of the present application will be described in detail below. Figure 12 The display method provided by another embodiment of the present application will be described in detail below.

[0258] The display method provided by the embodiments of the present application can be applied to a first electronic device, which is in communication connection with a second electronic device. The first electronic device can be an electronic device with a hardware structure as shown in Figure 3a and a software structure as shown in Figure 3b , Figure 3c , or an electronic device with more or fewer components than the figure, or combining certain components, or splitting certain components, or different component arrangement, and the like hardware structure and software structure.

[0259] The following takes the first electronic device as a mobile phone, the second electronic device as a car machine, and the scenario of maximizing the display interface as an example to describe the display method provided by the embodiments of the present application in detail. A plurality of applications are installed in the mobile phone, and part or all of the applications support the parallel horizon mode (i.e., support the in-application split-screen function) and the car machine has a display screen.

[0260] Reference Figure 12 As shown in the figure, Figure 12 A flowchart of the display method provided by another embodiment of the present application is shown, which can include steps S1201-S1204.

[0261] S1201: The mobile phone (as an example of the first electronic device) acquires the maximization operation request message (as an example of the first operation request message) sent by the car machine (as an example of the second electronic device) in the super desktop mode (as an example of the preset mode), which is sent by the car machine in response to the maximization operation (as an example of the first operation) on the music application small window interface (as an example of the first interface).

[0262] The music application small window interface includes a small window display window (as an example of the first display window), which can be used to display the music playing interface (as an example of the first application interface) of the "music" application (as an example of the target application).

[0263] In the embodiments of the present application, after the car machine starts the super desktop mode, when the user clicks the "music" application icon in the super desktop, the car machine can open the "music" application in the small window mode and display the home page interface of the "music" application through the virtual screen. When the user performs the operation of browsing the information in the home page interface, such as clicking to play a certain music, the car machine can display the corresponding music playing interface in the music application small window interface. Alternatively, when the user clicks the "music" application icon in the super desktop, the car machine can also open the "music" application in the small window mode through the virtual screen and directly display the music playing interface of the "music" application in the music application small window interface.

[0264] In the embodiments of the present application, after the car machine starts the super desktop mode, when the user performs the maximization operation on the music application small window interface, the car machine can generate the maximization operation request message in response to the maximization operation and send it to the mobile phone. The maximization operation can be used to maximize the music application small window interface to enter the full-screen state. Correspondingly, the mobile phone can receive the maximization operation request message sent by the car machine.

[0265] S1202: The mobile phone determines the screen size of the virtual screen corresponding to the "music" application in response to the maximization operation request message.

[0266] S1203: The phone starts the Parallel View mode and generates a music application split-screen interface (as an example of the second interface) based on the screen size of the virtual screen in the Parallel View mode. The music application split-screen interface can include a left display window (as an example of the second display window) and a right display window (as an example of the third display window) for split-screen display. The left display window and the right display window are used to display the music playback interface and the home screen of the "Music" application (as an example of the second application interface), respectively.

[0267] In this embodiment, the size of the music application split-screen interface can be the same as the size of the vehicle's display screen, meaning the second interface is full-screen. The sizes of the left and right display windows of the music application split-screen interface can be the same or different. The left and right display windows can be split vertically or horizontally; this embodiment describes a horizontal split-screen as an example. The left and right display windows can occupy all or part of the music application split-screen interface. This embodiment does not impose specific limitations on the position and size of the left and right display windows. Preferably, in this application, the height of a single window in the parallel view can be greater than its width, meaning the height of both the left and right display windows is greater than their width.

[0268] S1204: The mobile phone outputs control data for the music application split-screen interface (as an example of the first control data). The control data for the music application split-screen interface is used to control the vehicle system to display the music application split-screen interface on the screen.

[0269] It should be noted that the specific content of steps S1201 to S1204 in the embodiments of this application can be found by referring to Figure 4 The relevant content in steps S401 to S407 of the illustrated embodiment will not be repeated here.

[0270] Furthermore, in the above embodiments, only the portrait split-screen method has been described. The display method for the landscape split-screen method can be the same as that for the portrait split-screen method. For details, please refer to the display process for the portrait split-screen method, which will not be repeated here.

[0272] The second electronic device is used to activate a preset mode and display a first interface in the preset mode. The first interface includes a first display window, which is used to display the first application interface of the target application. In response to a first operation on the first interface, a first operation request message is sent to the first electronic device. The first operation includes maximizing the first interface.

[0273] The first electronic device is configured to obtain a first operation request message sent by the second electronic device; in response to the first operation request message, determine a screen size of a virtual screen corresponding to the target application; start a parallel view mode, and generate a second interface of the virtual screen based on the screen size of the virtual screen in the parallel view mode; the second interface includes a second display window and a third display window displayed in a split screen mode, and the second display window and the third display window are respectively configured to display a first application interface and a second application interface of the target application; and output first control data, the first control data being configured to control the second electronic device to display the second interface on the display screen.
