Detailed Implementation
[0019] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. Based on the embodiments of this application, every other embodiment obtained by those skilled in the art without inventive effort falls within the scope of protection of this application.
[0020] To facilitate understanding of this embodiment, the following description will use the application display method provided in this application embodiment applied to an intelligent cockpit system as an example to illustrate the above exemplary steps provided in this application embodiment.
[0021] Please see Figure 1 , Figure 1 This is a flowchart illustrating an application display method provided in an embodiment of this application. Figure 1 As shown in the embodiments of this application, the application display method includes: Step S101: When the current application window meets the preset refresh conditions, determine whether there is window overlay in the current application window.
[0022] The current application window can refer to the window in the smart cockpit system that is currently interacting with the user in the foreground. The current application includes multiple active windows, and the current application window is the window of the current application that is currently interacting with the user in the foreground. The current application window can be a window displayed on the screen of the car's smart cockpit. As an example, the current application window can be the account login window in a music application.
[0023] Specifically, it can monitor the content displayed in the current application window and determine whether there is window overlap when the current application window meets the preset refresh conditions.
[0024] The preset refresh conditions include at least one of the following: size change, brightness mode change, configuration information change. For example, the preset refresh conditions may be a change in the size of the current application window, such as the length and width. The preset refresh conditions may also be a change in the current application window from bright mode (daytime mode) to dark mode (nighttime mode). The preset refresh conditions may also be a change in configuration information such as image quality level.
[0025] Step S102: If window overlay exists, determine whether the current application window has a transparent bottom based on the window display modes of the current application window and the lower layer application window.
[0026] In intelligent cockpit systems, windows for video, music, and reading are typically in full-screen mode, while windows related to account login, user agreements, and permission settings are in non-full-screen mode. When a non-full-screen window of a third-party application is superimposed on a full-screen window (such as an account login window superimposed on a video window), if the status bar and navigation bar areas are transparent, the video interface will be displayed below the status bar and navigation bar areas instead of the system background, resulting in a situation where the video interface is visible underneath.
[0027] The following reference Figure 2 This section describes the process of determining whether the current application window has a transparent bottom.
[0028] Figure 2 A flowchart illustrating the bottom-determining steps provided in an embodiment of this application is shown, as follows: Figure 2 As shown, the steps for determining the transparency include: Step S1021: Determine whether the current application window and the lower-level application window meet the preset mode conditions based on the window display modes of the current application window and the lower-level application window.
[0029] The lower-level application window can refer to the application window located in the next display layer of the current application window. For example, if the current application window is the application window displayed in the first layer (top layer) of the graphical user interface of the intelligent cockpit system, then the lower-level application window is the application window displayed in the second layer.
[0030] Window display mode refers to the display mode of the application window. Window display mode includes full-screen mode and non-full-screen mode. For example, when the application window is displayed in full-screen mode, the window display mode is full-screen mode; when the application window is displayed in non-full-screen mode, the window display mode is non-full-screen mode.
[0031] Preset mode conditions refer to the conditions set for the window display mode. Preset mode conditions include the current application window being in non-fullscreen mode and the underlying application window being in fullscreen mode.
[0032] For example: Determine whether the current application window's display mode is non-fullscreen and whether the underlying application window's display mode is fullscreen. If the current application window's display mode is non-fullscreen and the underlying application window's display mode is fullscreen, then the preset mode condition is met; if the current application window's display mode is fullscreen, or the underlying application window's display mode is non-fullscreen, then the preset mode condition is not met.
[0033] Step S1022: If the preset mode conditions are met, determine whether the target area meets the preset transparency conditions.
[0034] Specifically, since the current application window is in non-fullscreen mode, a status bar and navigation bar are set at the edge of the screen. If the status bar and navigation bar are transparent, the user can see the application window below through the status bar and navigation bar, which means there is a "bottom-through" effect.
[0035] Therefore, after determining that the current application window and its underlying application windows meet the preset mode conditions, it is necessary to further determine whether the target area in the graphical user interface is transparent. If the target area is transparent, it is determined that the target area meets the preset transparency conditions; if the target area is not transparent, it is determined that the target area does not meet the preset transparency conditions. The target area can refer to the area corresponding to the system bar; for example, the target area could be the area corresponding to the status bar or navigation bar.
[0036] Step S1023: If the preset transparency conditions are met, it is determined that the current application window has a transparent bottom.
[0037] If the target area meets the preset transparency conditions, it indicates that the display area of the current application window is smaller than the display area of the underlying application window. Since the target area is transparent, the content of the underlying application window can be seen outside the display area of the current application window, confirming a "leaking background" issue. Therefore, a full-screen background layer needs to be created for the current application window to prevent the content of the underlying application window from being seen, thus fixing the "leaking background" problem.
[0038] Step S103: If the current application window has a transparent background, then when the current application window meets the layer addition conditions, add a full-screen background layer to the current application window so as to display the current application window based on the full-screen background layer.
[0039] In one embodiment, it is necessary to first determine whether the current application window meets the conditions for adding layers. For example, determine whether the current application window has a background layer. If there is no background layer, then determine that the current application window meets the conditions for adding layers.
[0040] When the conditions for adding a layer are met in the current application window, set the layer color of the full-screen background layer according to the theme color, and generate a full-screen background layer below the current application window according to the layer color.
[0041] For example, if the current theme color of the intelligent cockpit system is blue, the layer color of the full-screen background layer can be set to blue, and a full-screen background layer can be generated according to the set layer color. The full-screen background layer can then be placed below the current application window to prevent the user from seeing the application window below, thus solving the problem of the current application window being transparent.
[0042] In one embodiment, in the intelligent cockpit system of a car, the lifecycle (activity) of the current application window is variable. When the current application window is removed from the current task stack, the lifecycle of the current application window will stop executing and the callback will end. At this time, the full-screen background layer needs to be removed synchronously to ensure the consistency of the lifecycle of the full-screen background layer with that of the current application window and to avoid any residue.
[0043] Specifically, determine whether the lifecycle of the current application window has changed.
[0044] In one scenario, if the lifecycle of the current application window changes—for example, the current application window is closed, a new application window is launched, or the current application window is switched to run in the background—then it is determined whether the current application window meets the preset layer conditions.
[0045] For example: determine whether the current application window has a corresponding full-screen background layer and whether the full-screen background layer is visible. If it is determined that the current application window has a corresponding full-screen background layer and the full-screen background layer is visible, then the preset layer condition is met; if it is determined that the current application window does not have a corresponding full-screen background layer or the existing full-screen background layer is not visible, then the preset layer condition is not met.
[0046] If the preset layer conditions are met, the full-screen background layer is removed; otherwise, the lifecycle of the current application window continues to be monitored.
[0047] In another scenario, if it is determined that the lifecycle of the current application window has not changed, then in response to control operations on the current application window, it is determined whether the current application window meets the preset layer conditions. If the preset layer conditions are met, the full-screen background layer is hidden. These control operations include, but are not limited to, dragging operations and multi-finger pinch-to-zoom operations.
[0048] Specifically, users can use control operations to zoom and move the current application window. For example, a multi-finger pinch operation on the current application window will shrink its size; a drag operation will move its position. To provide users with appropriate feedback when the size and position of the current application window change, the full-screen background layer can be temporarily hidden in the graphical user interface so that users can see the underlying application interface.
[0049] During the continuous control operation, if the current application window is detected to have a corresponding full-screen background layer and the full-screen background layer is visible, then the preset layer condition is determined to be met; if the current application window is detected to not have a corresponding full-screen background layer or the existing full-screen background layer is not visible, then the preset layer condition is determined not to be met.
[0050] If the preset layer conditions are met, it means that the full-screen background layer is obscuring the application window below. In this case, the full-screen background layer is hidden so that the user can see the part of the application window below that is obscured by the full-screen background layer. If the preset layer conditions are not met, it means that the full-screen background layer is not obscuring the application window below. In this case, there is no need to hide the full-screen background layer. When a control operation ends, the underlying application window needs to be obscured to prevent the background from showing through. For example, in response to the end of a control operation, the full-screen background layer can be changed from hidden to visible. The application display method provided in this application embodiment can determine whether the current application window has a background transparency issue when window overlap occurs. If a background transparency issue is confirmed, a full-screen background layer is added to the current application window, completing visual repair at the system level without modifying the application's source code. This avoids the cost of repeated communication with third-party application providers, effectively improves system compatibility and user experience, and solves the interface background transparency problem caused by incompatibility between third-party applications and the smart cockpit system.
[0051] Based on the same inventive concept, this application also provides an application display device corresponding to the application display method. Since the principle of the device in this application is similar to the application display method described above, the implementation of the device can refer to the implementation of the method, and the repeated parts will not be described again.
