[0082] The present application provides a method for displaying a dynamic wallpaper and an electronic device, which are used to improve the display flexibility and display effect of the dynamic wallpaper of the electronic device, so as to ensure the user experience.

[0083] The following explains some terms in the present application to facilitate the understanding of those skilled in the art.

[0084] 1), An electronic device is a device or apparatus with data connection function, data calculation and processing, and interface display function.

[0085] Exemplarily, the electronic device in the present application can be a tablet computer, a personal computer (PC), a laptop computer, a computer, a netbook, a vehicle-mounted computer, a smart phone, a smart wearable device (such as a smart watch, a smart bracelet, smart glasses, etc.). Of course, the electronic device can also be various portable devices, vehicle-mounted terminal devices, personal digital assistants (PDAs), smart home devices (such as smart TVs, etc.) and other smart devices. The present application does not limit the specific form of the electronic device.

[0086] The electronic device can implement its functions through the operating system installed, and provide services for users. Exemplarily, the electronic device can, but is not limited to, be installed with or other operating systems.

[0087] 2), The theme of the electronic device is used to define the appearance style of the user interface of the electronic device. The electronic device can save one or more themes. These themes can, but are not limited to, include the themes preset in the operating system, the themes provided by third-party applications, and the themes downloaded by users from the server. Users can select one of the themes as the theme configuration of the electronic device. Usually, the default theme adopted when the electronic device is powered on for the first time is the theme preset in the operating system. The main interface, lock screen interface, and other user interfaces displayed by the electronic device all conform to the appearance style defined by the theme currently set by the electronic device.

[0088] Traditional theme solutions can include at least one of the following: wallpaper, background design, color scheme, font and text style, icon design, control style, display element layout and spacing, animation design, navigation mode, light and dark mode, etc.

[0089] Compared with traditional theme solutions, the wallpaper in a theme with an animation function (hereinafter simply referred to as an animation theme) can be a dynamic wallpaper. Optionally, an interaction object, that is, an object that interacts with the user, can also be defined in the animation theme. The interaction object can be displayed in the wallpaper and can also be displayed in other user interfaces opened by the user. Exemplarily, such as Figure 1As shown in (a) and (b) therein, after setting the dynamic effect theme, the electronic device can display a dynamic wallpaper including interactive objects on the lock screen interface and the home screen interface.

[0090] It should be noted that the specific image of the interactive object in the dynamic effect theme of this application is not limited. It can be a character, an animal created through animation technology, or an abstract object, etc. In some scenarios, the interactive object can also be called a "desktop pet".

[0091] Optionally, the dynamic wallpaper in the dynamic effect theme can include two parts: a background image and an interactive object; or the dynamic wallpaper is an inseparable whole, and the specific composition form of the dynamic wallpaper in this application is not limited.

[0092] It should be understood that in the embodiments of this application, "at least one" means one or more, and "a plurality" means two or more. "And / or" describes the association relationship of associated objects and indicates that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone, where A and B can be singular or plural. The character " / " generally represents an "or" relationship between the associated objects before and after. "At least one (item) of the following" or its similar expression refers to any combination of these items, including any combination of single item (s) or plural items (s). For example, at least one (item) of a, b, or c can represent: a, b, c, a and b, a and c, b and c, or a, b, and c, where a, b, and c can be single or multiple.

[0093] In the embodiments of this application, descriptions such as "when...", "in the case of...", "if", and "if" all refer to that the device will perform corresponding processing under a certain objective situation, which does not limit the time, and it is not required that the device must have a judgment action when implementing, nor does it mean that there are other limitations.

[0094] It should be noted that in this application, "for indicating" can include for directly indicating and for indirectly indicating. When describing that a certain information is used to indicate A, it can include that the information directly indicates A or indirectly indicates A, and it does not mean that the information must carry A. Taking the first information being used to indicate the first content as an example, the first information can include the first content, or a part of the first content, or an identifier, index, indicator, etc. of the first content, and can also include an algorithm for determining the first content, calculation parameters, etc. This application does not limit the way of "indicating".

[0095] In this application, "including / comprising A" can be equivalent to "including / comprising A information". A information is used to indicate A.

[0096] In addition, it should be understood that in the description of this application, terms such as "first" and "second" are only used for the purpose of distinguishing descriptions, and should not be construed as indicating or implying relative importance, nor as indicating or implying an order.

[0097] As described in the background art, the current display method of dynamic wallpapers is not flexible enough and the display effect is not good. Based on this, the embodiments of this application provide a dynamic wallpaper display method and an electronic device. Through this method, during the process of displaying a dynamic wallpaper, the electronic device can display the animation effect of the wallpaper in real time according to the user's operation or the running status of the services running in the background. This method can enable the dynamic wallpaper of the electronic device to generate an animation effect according to the user's operation, so as to realize interaction with the user and improve the interest of the dynamic wallpaper; or enable the animation effect of the dynamic wallpaper to reflect the running status of the background service to remind the user and improve the functionality of the dynamic wallpaper. In short, the method provided by the embodiments of this application can improve the flexibility and display effect of the dynamic wallpaper.

[0098] The following will describe in detail the solution provided by the embodiments of this application with reference to the accompanying drawings.

[0099] The embodiments of this application provide an electronic device that can implement the dynamic wallpaper display method provided by the embodiments of this application.

[0101] The processor 210 may include one or more processing units. For example, the processor 210 may include a central processing unit (CPU), an application processor (AP), a modem processor, a graphics processing unit (GPU), an image signal processor (ISP), a controller, a memory, a video codec, a digital signal processor (DSP), a baseband processor, and / or a neural-network processing unit (NPU), etc. Among them, different processing units may be independent devices or integrated in one or more processors. Among them, the controller may be the nerve center and command center of the electronic device 200. The controller can generate operation control signals according to the instruction operation code and timing signal to complete the control of fetching and executing instructions.

[0102] A memory may also be provided in the processor 210 for storing instructions and data. In some embodiments, the memory in the processor 210 is a cache memory. This memory can save the instructions or data that the processor 210 has just used or recycled. If the processor 210 needs to use the instruction or data again, it can be directly called from this memory. By providing the memory, the number of data accesses of the processor 210 to the internal memory 221 can be reduced, the waiting time of the processor 210 is reduced, and thus the efficiency of the system is improved.

[0103] The dynamic wallpaper display method provided by the embodiments of the present application can be controlled by the processor 210 or other components can be called to complete it. For example, the software program of the embodiments of the present application stored in the internal memory 221 is called to render the animation effect of the dynamic wallpaper and control the display screen 294 to display the animation effect. The processor 210 may include different devices. For example, when the CPU and GPU are integrated, the CPU and GPU can cooperate to execute the dynamic wallpaper display method provided by the embodiments of the present application. For example, part of the software operation in this method is executed by the CPU, and another part of the algorithm for animation effect display is executed by the GPU to obtain a faster processing efficiency.

[0104] The display screen 294 is used to display images, videos, etc. The display screen 294 includes a display panel.

The display screen 294 can be used to display information input by the user or information provided to the user, as well as various graphical user interfaces (GUIs). For example, the display screen 294 can display windows, photos, videos, web pages, or files, etc. In addition, it can be understood that in some embodiments, the status bar may also include a Bluetooth icon, a WiFi icon, an external device icon, etc. In some embodiments, when the processor 210 detects a touch operation of the user's finger (or stylus, etc.) on the display screen, in response to the touch operation, the processor 210 can execute the action corresponding to the touch operation. In some embodiments, when the processor 210 detects an input event input by an external input device (such as a mouse, a keyboard, etc.) of the electronic device 200, in response to the input event, the processor 210 can execute the action corresponding to the input event. When the electronic device starts the dynamic effect theme, the processor 210 can control the display screen 294 to display the dynamic wallpaper in the dynamic effect theme on the display screen, as well as the dynamic effect of the dynamic wallpaper.

[0105] In an embodiment of the present application, the electronic device 200 is a foldable electronic device. Then, a certain display screen 294 of the electronic device 200 can be an integrated flexible display screen, or a spliced display screen composed of two rigid screens and a flexible screen located between the two rigid screens. By performing a folding operation on the electronic device 200, the display screen can change its folding state. Optionally, in the method provided in the embodiment of the present application, when the electronic device 200 is in the folded state, the electronic device 200 can display a dynamic wallpaper and the dynamic effect of the dynamic wallpaper on the outer screen (the display screen exposed outside); when the electronic device 200 is in the unfolded state, the electronic device 200 can display a dynamic wallpaper and the dynamic effect of the dynamic wallpaper on the inner screen or the unfolded screen (for example, the display screens in the dual-screen state or the triple-screen state of a triple-fold mobile phone).

[0106] In some embodiments, according to the different functions of the multiple display screens 294 in the electronic device 200, the multiple display screens 294 in the electronic device 200 can include a main screen and a secondary screen. The main screen is used to run the main tasks of the electronic device 200, display and complete the main functions of the electronic device, such as making and receiving calls, browsing the web, editing documents, watching videos, etc. The secondary screen serves as an extended working space and can run the secondary tasks of the electronic device 200. Optionally, the electronic device 200 can be a foldable electronic device. When the electronic device 200 is in the folded state, the electronic device 200 can display a dynamic wallpaper and the dynamic effect of the dynamic wallpaper on the outer screen; in addition, when the electronic device 200 is in the unfolded state, the electronic device 200 can display a dynamic wallpaper and the dynamic effect of the dynamic wallpaper on the main screen.

This input device interface may reuse the USB interface 230 or be a dedicated interface set separately. The present application does not make any limitations in this regard.

[0120] It should be understood, Figure 2The illustrated electronic device 200 is merely an example and does not constitute a limitation on the electronic device. In practical applications, the electronic device 200 may have more or fewer components than those shown in the figure, may combine two or more components, or may have different component configurations. The various components shown in the figure may be implemented in hardware, software, or a combination of hardware and software including one or more signal processing and / or application specific integrated circuits.

[0121] Figure 2 The hardware structure of the electronic device is introduced. Next, the software structure of the electronic device will be described. The software system of the electronic device provided in the embodiments of this application may adopt a layered architecture, an event-driven architecture, a microkernel architecture, a microservices architecture, or a cloud architecture. Taking the layered architecture as an example in the embodiments of this application, reference Figure 3 is made to exemplarily illustrate the software structure of the electronic device.

[0122] The layered architecture divides the software in the electronic device into several layers, and each layer has a clear role and division of labor. Communication can be carried out between layers through software interfaces. As Figure 3 shown, the software structure of the electronic device at least includes, from top to bottom: an application layer, a system service layer, and a kernel layer. In addition, the electronic device may further include a hardware abstraction layer (HAL), and the HAL may also be referred to as the hardware layer, which is used to provide hardware resource support for the electronic device.

[0123] The application layer is the topmost layer of the operating system and includes the native applications of the operating system and the installed third-party applications, such as the camera, gallery, calendar, Bluetooth, music, video, information, calculator, chat application, video application, music application, electronic map application, social application, and so on.

[0124] The system service layer is an important part of the operating system of the electronic device and includes multiple system services provided by the operating system. For example, the system service layer may include: window management service, running management service, notification management service, layer management service, input management service, etc.

[0125] Window management service, which is used to manage the display and configuration of windows. The window management service can control the display of windows or interfaces on the display screen based on the display screen configuration and multiple management functions, adjust the transparency, position, size, etc. of the windows or interfaces, and can also have functions such as locking the screen and taking screenshots. The window management service can obtain parameter configurations such as the size and resolution of the display screen, and can also identify display areas such as the status bar in the user interface. Optionally, when the electronic device enters the split-screen mode, the window management service can also be used to manage the display and configuration of the window library in each split screen. When the appearance of the electronic device is set to a certain theme (such as an animation theme), the window management service can control the display of the user interface according to the display-related content defined in the theme. For example, the window management service can display a dynamic wallpaper and the user interface on the display screen according to the content in the currently set animation theme. For example, in the embodiments of the present application, the window management service can render and display the animation effect of the dynamic wallpaper on the display screen according to the user operation through the layer management service.

[0126] Operation management service, which is responsible for the startup switching, scheduling of each component in the system, and the management and scheduling of applications, etc.

[0127] Notification management service, which can enable an application to display notification information in the status bar and can also be used to convey notification-type messages. These messages can automatically disappear after a short stay without user interaction.

[0128] Input management service, which is used to collect, process user operation information and distribute input events. For example, after receiving the operation information reported by the touch drive or other input device drives (such as keyboard drive, mouse drive, etc.), the input management service can convert it into an input event and distribute the input event to other modules for processing.

[0129] Layer management service, which provides an independent service for the operating system of the electronic device and belongs to the underlying resident service of the operating system of the electronic device. During the operation of the device, the layer management service needs to run continuously, and the operating system will give priority to allocating resources to it to ensure that the service can perform image synthesis at any time, so as to ensure that the electronic device can display the user interface in real time. The layer management service is mainly responsible for functions such as layer establishment and control management, synthesizes and renders the image frames of the windows corresponding to the layers in each layer, and finally synthesizes the graphic frames in all layers into the image of the user interface that needs to be finally displayed on the display screen.

[0130] Optionally, between the application layer and the system service layer, the software structure of the electronic device may further include an application framework layer (FWK) (not shown in the figure). The application framework layer can provide application programming interfaces (APIs) and programming frameworks for the applications in the application layer. The application framework layer may include some predefined functions. Exemplarily, the application framework layer may include a content provider, a view system, a resource manager, etc. Among them, the content provider is used to store and obtain data, and make this data accessible to the applications in the application layer. The view system includes visible controls, such as controls for displaying text, pictures, documents, and other content; the controls in the view system can be used to construct the user interface of the application.

[0131] The Kernel layer provides the core system services of the operating system. Services such as security, memory management, process management, network protocol stack, and driver model are all implemented based on the Kernel layer. The Kernel layer also serves as an abstraction layer between the hardware and the software stack. There are many driver programs related to the electronic device in this layer. The main drivers are: display driver; keyboard driver; mouse driver; Flash driver for memory technology devices; camera driver; audio driver; Bluetooth driver; WiFi driver; touch driver, etc.

[0132] HAL is an interface layer between the operating system kernel of the electronic device and the hardware circuit, and its purpose is to abstract the hardware. Exemplarily, HAL may include various hardware in the electronic device, such as various sensors, display screens, cameras, a hardware composer (HWC), etc. Among them, the HWC is mainly responsible for image synthesis and image display, etc.

[0133] It should be noted that Figure 3 Only as an example of the software structure of an electronic device, only some levels and software modules are simply listed, and it does not impose any limitation on the software structure of the electronic device. In practical applications, the operating system of the electronic device may further include other levels, or each level may further include other software modules for implementing one or more functions or services. Additionally, the embodiments of the present application do not limit the specific levels where each software module is located. For example, some system services in the system service layer can be deployed in the application framework layer or in the Kernel layer.

[0134] In addition, the embodiments of the present application do not specifically limit the names of each software module in this software structure. For example, in In an operating system, the window management service can be WindowManagerServer (abbreviated as WMS), the layer management service can be the layer management engine (SurfaceFlinger), and the input management service can be InputManagerService. Operating system In it, the window management service can be SceneBoard (abbreviated as SCB), the layer management service can be the rendering service (RenderService, RS), and the input management service can be the multimode input service.

[0135] To improve the flexibility and display effect of dynamic wallpapers, this application provides a dynamic wallpaper display method. This method can be applied to an electronic device as Figure 2 shown, and the software structure of the electronic device can be as Figure 3 shown. Now refer to the flowchart as Figure 4 shown to describe in detail the method provided by the embodiments of this application.

[0136] S401: The electronic device displays a first wallpaper on the display screen.

[0137] Optionally, the electronic device can display the first wallpaper on the display screen based on the currently set animation theme. This first wallpaper is the dynamic wallpaper.

[0138] According to specific application scenarios, the electronic device can display the first wallpaper on the lock screen interface, the home screen interface, or other interfaces (such as the picture-in-picture interface, the floating window interface). Exemplarily, as Figure 1 shown, the electronic device can display the first wallpaper on the lock screen interface or the home screen interface.

[0139] S402: In response to a first user operation by the user that makes the electronic device approach another electronic device, the electronic device displays a first animation effect of the first wallpaper on the display screen.

[0140] In practical applications, the user can achieve certain interaction purposes by making two electronic devices approach each other, such as pairing to establish a connection, information exchange, content transmission, etc. For example, the current device's "tap to share" function.

[0141] Optionally, the electronic device can detect the presence of other electronic devices nearby based on wireless communication technology, thereby detecting that the user performs a first user operation of bringing the two electronic devices closer. Exemplarily, the wireless communication technology can include: near field communication (NFC) technology, Bluetooth (BT) technology (e.g., ordinary BT technology, Bluetooth low energy (BLE) technology), wireless-fidelity (WiFi) technology, ZigBee technology, ultra wideband (UWB) technology, or XingShan technology, etc.

[0142] In one implementation, the electronic device can execute S402, displaying the first animation effect, through the following steps:

[0143] Step A1: The electronic device obtains the status information of the electronic device during the execution of the first user operation.

[0144] Step A2: The electronic device displays the first animation effect on the display screen according to the obtained status information of the electronic device;

[0145] Among them, the status information of the electronic device includes at least one of the following: device movement direction, relative position information between the electronic device and the other electronic device, target screen position information, device movement speed; the target screen position information is used to indicate the screen position on the display screen of the electronic device that is closest to the other electronic device.

[0146] Based on the different contents included in the status information of the electronic device, the electronic device can display the first animation effect of the first wallpaper through Implementation Method 1 to Implementation Method 4 as follows.

[0147] Implementation Method 1: When the status information of the electronic device includes the device movement direction, the first animation effect is the animation effect that the content in the first wallpaper moves or gathers in the device movement direction.

[0148] Exemplarily, as Figure 5A shown in (a) and (b) of, the lock screen interface of mobile phone 1 displays dynamic wallpaper 1, and dynamic wallpaper 1 contains a kitten; the lock screen interface of mobile phone 2 displays dynamic wallpaper 2, and dynamic wallpaper 2 contains a fish. As Figure 5B shown in (a) of, when mobile phone 1 is on the left and mobile phone 2 is on the right, and the two mobile phones are approaching (i.e., mobile phone 1 moves to the right and mobile phone 2 moves to the left), mobile phone 1 can display the animation effect that the kitten in dynamic wallpaper 1 runs to the right, and mobile phone 2 can display the animation effect that the fish in dynamic wallpaper 2 swims to the left. As Figure 5BAs shown in (b) of the figure, when Phone 2 is on the left and Phone 1 is on the right, and the two phones approach each other (i.e., Phone 2 moves to the right and Phone 1 moves to the left), Phone 1 can display the animation effect of the kitten running left in Dynamic Wallpaper 1, and Phone 2 can display the animation effect of the fish swimming right in Dynamic Wallpaper 2. As Figure 5B shown in (c) of the figure, when Phone 1 is on the top and Phone 2 is on the bottom, and the two phones approach each other (i.e., Phone 1 moves down and Phone 2 moves up), Phone 1 can display the animation effect of the kitten running down in Dynamic Wallpaper 1, and Phone 2 can display the animation effect of the fish swimming up in Dynamic Wallpaper 2. As Figure 5B shown in (d) of the figure, when Phone 1 is on the bottom and Phone 2 is on the top, and the two phones approach each other (i.e., Phone 1 moves up and Phone 2 moves down), Phone 1 can display the animation effect of the kitten jumping up in Dynamic Wallpaper 1, and Phone 2 can display the animation effect of the fish swimming down in Dynamic Wallpaper 2. It should be noted that if one of the phones does not move, this phone can not display the animation effect of its dynamic wallpaper currently.

[0149] Implementation Method 2: When the status information of the electronic device includes the relative position information between the electronic device and the other electronic device, the first animation effect is the animation effect that the content in the first wallpaper moves or gathers in the direction of the other electronic device. Exemplarily, the first animation effect can refer to the one in Implementation Method 1 Figure 5B as shown.

[0150] Implementation Method 3: When the status information of the electronic device includes the target screen position information, the first animation effect is the animation effect that the content in the first wallpaper moves or gathers to the screen position indicated by the target screen position information, or the first animation effect is the animation effect generated by the content in the first wallpaper within the screen position indicated by the target screen position information.

[0151] Optionally, the electronic device can determine the relative position information between the electronic device and the other electronic device, and based on this relative position information, determine the target screen position information.

[0152] In this Implementation Method 3, when the first animation effect is the animation effect that the content in the first wallpaper moves or gathers to the screen position indicated by the target screen position information, this first animation effect is similar to the first animation effect in Implementation Method 1 or Implementation Method 2, and will not be elaborated here.

[0153] The first animation effect is the animation effect generated by the content in the first wallpaper within the screen position indicated by the target screen position information, that is, there is an animation effect generated at the screen position indicated by the target screen position information in the first wallpaper. Continuing with the example of the Figure 5A two phones, when Phone 1 and Phone 2 approach each other and the status is as Figure 5CWhen shown as such, the mobile phone 1 can display the animation effect of the kitten in the dynamic wallpaper 1 moving within the screen position 1, and the mobile phone 3 can display the animation effect of the fish in the dynamic wallpaper 2 moving within the screen position 2. Among them, the screen position 1 is the screen position on the display screen of the mobile phone 1 that is closest to the mobile phone 2; the screen position 2 is the screen position on the display screen of the mobile phone 2 that is closest to the mobile phone 1.

[0154] Implementation method 4: When the status information of the electronic device includes the device moving speed, the change amplitude or moving speed of the content of the first wallpaper in the first animation effect is positively correlated with the device moving speed.

[0155] Optionally, the electronic device can determine the device moving speed based on the sensing data collected by its own acceleration sensor.

[0156] Continuing with Figure 5A the two mobile phones as an example for illustration, when the mobile phone 1 slowly approaches the mobile phone 2, the mobile phone 1 can display the animation effect that the kitten in the dynamic wallpaper 1 slightly increases in volume, as shown in Figure 5D (a) in; when the mobile phone 1 quickly approaches the mobile phone 2, the mobile phone 1 can display the animation effect that the kitten in the dynamic wallpaper 1 becomes even larger in volume, as shown in Figure 5D (b) in.

[0157] It should also be noted that in the embodiments of the present application, when the first wallpaper is an indivisible whole, the first animation effect can be the animation effect of the whole first wallpaper; when the first wallpaper includes a background image and an interactive object, the first animation effect of the first wallpaper includes at least one of the following: the animation effect of the background image, the animation effect of the interactive object. Among them, the interactive object is an image that interacts with the user defined in the first theme currently set by the electronic device. The action performed by the interactive object in the animation effect of the interactive object matches the image of the interactive object. For example, the actions performed by the kitten in the dynamic wallpaper 1 and the fish in the dynamic wallpaper 2 as described above are running and jumping, and swimming respectively. Figures 5B to 5D in.

[0158] The embodiments of the present application provide a method for displaying an animated wallpaper. In this method, during the process of displaying the dynamic wallpaper, the electronic device can display the animation effect of the wallpaper in real time according to the user operation of bringing two electronic devices closer. This method can enable the dynamic wallpaper of the electronic device to generate an animation effect according to the user operation of bringing two electronic devices closer, thereby realizing interaction with the user and improving the interest of the dynamic wallpaper. The method provided by the embodiments of the present application can improve the flexibility and display effect of the dynamic wallpaper.

[0159] To improve the flexibility and display effect of the dynamic wallpaper, the present application provides a method for displaying a dynamic wallpaper. This method can be applied to the electronic device as shown in Figure 2 , and the software structure of this electronic device can be as shown in Figure 3See below. Figure 6 The flowchart shown is a detailed description of the method provided in the embodiment of the present application.

[0160] S601: The electronic device displays a first wallpaper on a display screen.

[0161] and Figure 4 S401 in the illustrated embodiment is similar and will not be described in detail here.

[0162] S602: The electronic device displays a second motion effect of the first wallpaper on the display screen in response to a second user operation performed by the user on the first wallpaper.

[0163] It should be noted that the present application does not limit the operation type of the second user operation. Exemplarily, the second user operation can be any one of the following: a single-click operation, a continuous click operation, a short-press operation, a long-press operation, a sliding operation, and a drag operation.

[0164] In one implementation, the electronic device may perform S602 by the following steps to display the second motion effect:

[0165] Step B1: The electronic device obtains operation information of the second user.

[0166] Step B2: The electronic device displays a second animation on the display screen according to the operation information of the second user.

[0167] The operation information of the second user operation includes at least one of the following: a first operation position, a first operation type, and a first operation duration.

[0168] Based on the different contents included in the operation information of the second user operation, the electronic device can display the second motion effect of the first wallpaper through the following implementation methods 1 to 3.

[0169] Implementation method 1: When the operation information includes the first operation position, the second animation is an animation in which the content in the first wallpaper moves or gathers toward the first operation position; or the second animation is an animation in which part of the content in the first wallpaper changes in amplitude or position with the first operation position as the initial position.

[0170] Continue with Figure 5A Take the mobile phone 2 in the example as an example, when the user clicks a certain position in the dynamic wallpaper 2 of the mobile phone 2, Figure 7A As shown in (a) in FIG. 1 ; mobile phone 2 can display the dynamic effect of the fish in dynamic wallpaper 2 swimming toward the position, such as Figure 7A As shown in (b); or, the mobile phone can display the fish in the dynamic wallpaper 2 from the original position to the user's operation position, and the amplitude changes (ie, becomes larger) at the user's operation position, such as Figure 7A As shown in (c) in .

[0171] Implementation method 2: When the operation information includes the first operation type, the action type performed by the content in the first wallpaper in the second dynamic effect corresponds to the first operation type.

[0172] Through this implementation method 2, the display content of the second dynamic effect is related to the operation type of the second user operation. That is, when the user performs different user operations on the first wallpaper, the electronic device can display different dynamic effects of the first wallpaper.

[0173] Exemplarily, when the second user operation is a click operation, the second dynamic effect can be any random dynamic effect among multiple dynamic effects of the first wallpaper; when the second user operation is a swipe operation, the second dynamic effect can be a dynamic effect in which the content in the first wallpaper moves in the swipe direction; when the second user operation is a drag operation, the second dynamic effect can be a dynamic effect in which the user drags the content in the drag direction; when the second user operation is a long press operation, the content in the first wallpaper can change in amplitude; when the second user operation is a short press operation, the content in the first wallpaper can change by flashing.

[0174] Continuing with Figure 5A the mobile phone 2 in Figure 7B as an example, when the user clicks on a certain position in the dynamic wallpaper 2 of the mobile phone 2 as shown in Figure 7B (a) in

[0175] the mobile phone 2 can display any random dynamic effect of the dynamic wallpaper 2, and this dynamic effect can be any one of the dynamic effects in

[0176] (b), (c), or (d) in

[0177] It should also be noted that in the embodiments of the present application, when the first wallpaper is an inseparable whole, the first dynamic effect can be the dynamic effect of the whole first wallpaper; when the first wallpaper includes a background image and an interactive object, the first dynamic effect of the first wallpaper includes at least one of the following: the dynamic effect of the background image, the dynamic effect of the interactive object. Among them, the interactive object is an image defined in the first theme currently set by the electronic device that interacts with the user. In the dynamic effect of the interactive object, the action performed by the interactive object matches the image of the interactive object.

[0178] The embodiment of the present application provides a method for displaying a dynamic wallpaper. In this method, in the process of displaying a dynamic wallpaper, the electronic device can display the dynamic effect of the wallpaper in real time according to the user operation performed by the user on the wallpaper. The method can enable the dynamic wallpaper of the electronic device to generate dynamic effects according to the user operation on the wallpaper, thereby realizing interaction with the user and improving the fun of the dynamic wallpaper. The method provided in the embodiment of the present application can improve the flexibility and display effect of the dynamic wallpaper.

[0179] In order to improve the flexibility and display effect of dynamic wallpaper, this application provides a dynamic wallpaper display method. The method can be applied to Figure 2 The electronic device shown in FIG. 1 may have a software structure as shown in FIG. Figure 3 See below. Figure 8 The flowchart shown is a detailed description of the method provided in the embodiment of the present application.

[0180] S801: The electronic device displays a first wallpaper on a display screen.

[0181] and Figure 4 S401 in the illustrated embodiment is similar and will not be described in detail here.

[0182] S802: The electronic device obtains user behavior information, where the user behavior information is used to indicate the user's behavior activities.

[0183] Optionally, the user's behavioral activities may include but are not limited to user body movements, user expressions, user emotions, etc.

[0184] In one implementation, the electronic device can obtain user behavior information by analyzing data collected by sensors, and the specific steps are as follows:

[0185] Step C1: The electronic device obtains sensor data collected by a sensor of the electronic device.

[0186] Optionally, the sensors of the electronic device may include but are not limited to: a microphone, an acceleration sensor, a gyroscope sensor, a temperature sensor, a photoplethysmography (PPG) sensor, etc.

[0187] Step C2: The electronic device determines user behavior information based on the sensor data.

[0188] In one implementation, the electronic device may determine the user behavior information by:

[0189] Method 1: When the sensor data includes an audio signal or an airflow vibration signal collected by the microphone of the electronic device, the electronic device can identify that the user performs a blowing operation on the electronic device according to the audio signal or the airflow vibration signal collected by the microphone; and determine user behavior information for indicating that the user performs a blowing operation on the electronic device.

[0190] Method 2: When the sensor data includes sensor data collected by the acceleration sensor or the gyroscope sensor of the electronic device, the electronic device can identify that the user performs a shaking operation on the electronic device according to the sensor data collected by the acceleration sensor or the gyroscope sensor; and determine user behavior information for indicating that the user performs a shaking operation on the electronic device.

[0191] S803: The electronic device displays a third dynamic effect of the first wallpaper on the display screen according to the user behavior information.

[0192] Optionally, the third dynamic effect corresponds to the behavior activity indicated by the user behavior information. That is, different behavior activities correspond to different dynamic effects of the first wallpaper. Based on this, in the embodiments of the present application, based on the differences in the user behavior activities indicated by the user behavior information, the third dynamic effects of the first wallpaper displayed by the electronic device are also different. For example, the electronic device can display the third dynamic effect through the following implementation methods.

[0193] Implementation method a: When the user behavior information is used to indicate that the user performs a blowing operation on the electronic device, the third dynamic effect is a dynamic effect in which the content in the first wallpaper moves in the blowing direction of the blowing operation.

[0194] Exemplarily, as shown in (a) of Figure 9A , a dynamic wallpaper 1 is displayed on the lock screen interface of the mobile phone 1, and the dynamic wallpaper 1 contains balloons. When the user blows on the mobile phone, the mobile phone 1 can display a dynamic effect in which the balloons in the dynamic wallpaper 1 move in the blowing direction, as shown in (b) of Figure 9A .
