Background
With the development of the internet of things technology, the vehicle-mounted system in the automobile is gradually developed, the functions are more and more, and the application carried by the vehicle-mounted system is more and more accordingly. When the car is designed in a car factory, because the screen of the car is generally very large, the screen is large, the design of a UI is a test, all functions cannot be plugged into an APP, so that the multi-window technology comes up with the car, and the car-mounted system can simultaneously display windows of multiple applications on the screen of the car. However, the multi-window technology seen by people at ordinary times does not provide a free customization function of a screen at all, and three or more applications cannot be customized in width and height positions and can not be freely typeset; often, a self-defined window is limited to preset applications bound with the window, so that when other applications which are not set are opened, the whole car machine screen cannot be reasonably arranged, and a plurality of applications cannot be perfectly spliced on the screen. Meanwhile, when the scenes of different window designs are switched, the phenomenon that the scenes are switched and delayed because whether the application is started or not and needs to be redirected or not even the application cannot be normally opened according to the requirements of the set window can be caused.
Disclosure of Invention
The invention aims to provide a multi-application window custom layout method on a vehicle-mounted system, and aims to solve the problem that the prior art can not more freely realize the simultaneous display of different applications under multiple scenes and the size and the position of a window custom on the premise of not binding the application window setting.
The multi-application window custom layout method on the vehicle-mounted system comprises the steps of firstly customizing scenes of various screen layouts in advance through a scene configuration file, wherein each scene corresponds to a scene ID, window information in each scene is the size of each window and corresponding screen coordinates under the scene, analyzing the scene configuration file when a task is started, displaying applications in a window size position in a WINDOWING _ MODE _ FREE MODE according to the obtained window information, when the scenes are switched, switching the vehicle-mounted system to the scene according to the specified scene ID, simultaneously checking through a corresponding package name list, finding that the applications in the package name list are not started, starting the corresponding applications, and when all the applications are started, uniformly adjusting the size and the position of the windows corresponding to the applications according to the window information configured by the scene.
Preferably, when a scene is newly built in the vehicle-mounted system, a new stack area is defined through preset scene configuration, a plurality of windows can be mounted in the stack area, each window is associated with one task, the stack area corresponding to a specified scene and the tasks in the stack area are displayed when the scene is switched, the stack areas corresponding to other scenes are hidden, and the tasks in the hidden stack areas are hidden outside the screen instead of being destroyed.
Preferably, when the workflow Activity is started, the task state needs to be cached, and when redirection starting occurs during the running of the application task, the task calls the cached task state strategy to realize the custom window layout.
Preferably, the vehicle-mounted system is a customized Android system, and two AIDL interfaces are provided for a user to realize a layout scene self-defining function and a seamless switching function of multi-window application through a desktop application Launcher APK.
Preferably, after the vehicle-mounted system is started, the preset scene configuration is sent to the desktop application Launcher APK through the setDefaultConfig interface to be cached locally.
Preferably, when a scene is switched, the vehicle-mounted system calls the interface changeSecen to realize scene switching according to the scene ID and acquire a packet name list corresponding to the scene, wherein the packet name list is used for carrying out one-to-one corresponding association on the application task and the layout window under the scene.
The invention has the following advantages:
the invention realizes the setting of the number of windows which can be opened simultaneously and the size and the position of each window through the scene configuration file, and the application only corresponds to each window in sequence after being opened, and does not need to be bound with the window information. Therefore, even if the application is not pre-installed, the multi-application on-screen display can be realized according to the configuration requirement, and any application can be arranged for a predefined scene.
Moreover, when different scenes are switched by the method, the method can also check according to the packet name list of the displayed scenes, the applications which should be opened but are not opened after switching can be automatically opened, the situation that the applications which should be left are lost and need to be opened again after entering the scenes is avoided, and the application tasks in the hidden scenes are not destroyed but are moved out of the screen to be hidden in the switching process, so that the applications do not need to be opened again during switching, the switching time is greatly shortened, and seamless switching is realized.
The logic of the Activity is changed in the ActityStarter. Java file in the Framework, so that the Task state is cached when the new workflow Activity is started, the application can be opened in the original scene according to the set window information when being redirected and started, and errors are avoided when the application is opened.
Drawings
FIG. 1 is a flowchart of a multi-application window custom layout method on a vehicle-mounted system according to the present invention.
Detailed Description
The following detailed description of the embodiments of the present invention will be given in order to provide those skilled in the art with a more complete, accurate and thorough understanding of the inventive concept and technical solutions of the present invention.
As shown in fig. 1, the invention provides a multi-application window custom layout method on a vehicle-mounted system, where the vehicle-mounted system is a customized Android system, and provides two aid dl interfaces through a desktop application Launcher APK to realize a layout scene custom function and a seamless switching function of multi-window application for a user.
On the android system, there are concepts of Stack and Task. Stack (Stack): the concept of virtual child screen is equivalent to that a plurality of stacks (tasks) can be owned under one screen, and a plurality of tasks can be owned by one Stack (Task), in general, only one Stack can be seen on the screen at the same time, and other stacks can be hidden. Task: all windows running on the Stack area, one Task corresponds to one application window, but an application may have multiple tasks running on one Stack at the same time.
The method is realized by a desktop application Launcher APK, and the main function of the desktop application is to define a new stack area, start multi-window service in the new stack area and realize the mounting of the multi-window application. The stack area is displayed as a scene, and the task is displayed in the window.
The method comprises the following steps:
1. firstly, the scenes of various screen layouts are pre-defined by a scene configuration file, and the window size and the screen coordinates are freely customized. In the scene configuration file, each scene corresponds to a scene ID and window information, and the window information is the size of each window and corresponding screen coordinates in the scene. The windows and the applications are not in binding relation, different applications are associated at any time according to scene windows, and the applications are deployed on a screen.
2. And sending the preset scene configuration to a desktop application Launcher APK through a setDefaultConfig interface to cache the scene configuration to the local.
3. When a scene is switched, the vehicle-mounted system calls the interface changeSecen to realize scene switching according to the scene ID and acquire a packet name list corresponding to the scene, wherein the packet name list is used for carrying out one-to-one corresponding association on an application task and a layout window under the scene. In the scene configuration, each window corresponds to different window information according to the ID (queeId) of the window, and the application is correspondingly associated to different windows according to the sequence when the window is opened, so that the relationship between the application and the window can be set through the sequence of the package name list, and the association between the application and the window information can be changed only by changing the sequence of the package name list.
4. The vehicle-mounted system firstly checks whether an application which is not started exists in the packet name list, if so, the application is started firstly, when a new Task is started, the Task needs to be started in a WINDOWING _ MODE _ FREEFORM MODE, otherwise, the Task is displayed in a full screen MODE and cannot be defined by a user-defined window size.
5. And when the system monitors that all the intercepted applications are started, the system starts to adjust the window of the associated application, and the size and the coordinates of the window are uniformly modified.
6. When a new scene is switched, the stack area corresponding to the appointed scene and the tasks in the stack area are displayed, the stack areas corresponding to other scenes are hidden, and the tasks in the hidden stack areas are not destroyed but hidden outside the screen. This is to make the effect of switching scenes seamless, otherwise, the application will be restarted when switching scenes again next time, and this process is sometimes long and may cause a jam.
Since some applications may have redirection start during running, similar to redirection of web pages, two jumps may occur when the application starts, such as a Baidu map, which is an advertisement page first and then jumps to a map home page. The redirected started application is likely to start in the new Stack so that the application cannot freely change the window size and coordinates. The system in the method adopts a customized ROM, changes the logic of the start Activity in the Activity Starter. Java file in the Framework, and needs to cache the Task state when the application starts the new Activity; when the application task is redirected and started during running, the task calls a cached task state strategy to realize self-defined window layout so as to avoid the problem that the application cannot freely change the size and the coordinate of the window.
By adopting the method, multi-application same-screen display can be realized according to configuration requirements even if the application is not pre-installed, the multi-application same-screen display is more free and convenient, and the setting and the change are convenient; when different scenes are switched, the detection can be carried out according to the package name list of the display scene, and the applications which should be opened but are not opened after the switching can be automatically started, so that the seamless switching is realized.
The invention is described above with reference to the accompanying drawings, it is obvious that the specific implementation of the invention is not limited by the above-mentioned manner, and it is within the scope of the invention to adopt various insubstantial modifications of the inventive concept and solution of the invention, or to apply the inventive concept and solution directly to other applications without modification.
