Specifically, the memory stores a computer program, the processor is used for acquiring a boot animation resource package of the vehicle-mounted system, determining drawing parameters and playing parameters of the boot animation resource, controlling the vehicle-mounted system to present a first segment resource package according to the drawing parameters and the playing parameters, and controlling the vehicle-mounted system to stop presenting the first segment resource package and present a second segment resource package according to the drawing parameters and the playing parameters to form a background fade-out animation effect in response to receiving an exit signal of the boot animation.
According to the vehicle control method, firstly, a startup animation resource package of a vehicle-mounted system is obtained, wherein the startup animation resource package comprises a first segment resource package and a second segment resource package, the first segment resource package comprises multi-frame image resources with opaque background, and the second segment resource package comprises multi-frame image resources with incremental background transparency. After the on-vehicle system on-vehicle animation resource package is obtained, drawing parameters and playing parameters of the on-vehicle animation can be confirmed, and the on-vehicle system is controlled to stop presenting multi-frame images with opaque background in the first segment resource package in response to the received on-vehicle animation exit signal, and multi-frame image resources with increasing background transparency in the second segment resource package are presented according to the drawing parameters and the playing parameters, so that an animation effect of fading out the on-vehicle animation background is finally formed. In the method, the gradual change effect of gradually changing the starting animation of the vehicle-mounted system from opaque multi-frame images to full-transparent multi-frame images is achieved by matching drawing parameters and playing parameters of the animation resource package.
Specifically, the boot animation resource package is located on a designated path in the vehicle-mounted system and can be named bootanimation-0.zip, wherein bootanimation is the name of the boot animation resource package; and 0 is displayID of the main screen and the auxiliary screen. After the boot animation resource package of the vehicle-mounted system is obtained, the drawing parameters and the playing parameters of the boot animation resources contained in the package can be determined by setting the interface and the parameters of an open graphics library OpenGL ES called by bootanimation. The rendering parameters may include the size of the window to be rendered, the image resources, etc. The playing parameters may include a playing image frame rate, a clip playing frequency, and the like.
Further, the vehicle-mounted system can be controlled to present multi-frame images with opaque background in a first segment resource package in the starting-up animation resource according to the drawing parameters and the playing parameters in the obtained starting-up animation resource package. When the exit signal of the startup animation is obtained, the exit signal of the startup animation can be responded, the presentation of the multi-frame image with opaque background in the first segment resource package is ended, the presentation of the multi-frame image resource with gradually increased background transparency in the second segment resource package is started according to the drawing parameters and the playing parameters, and finally, the animation effect of gradually fading out the background of the transition of the startup animation of the vehicle-mounted system from the opaque multi-frame image to the fully transparent multi-frame image can be formed, and the problem that the image lacks transition effect in the process of exiting the startup animation and entering the desktop interface of the vehicle-mounted system is solved.

According to the vehicle control method, the preset parameters of the boot animation resource package in the vehicle-mounted system can be used for drawing the image of the boot animation, and the animation effect of fading out the background is presented when the boot animation is exited, so that the problem that the picture jumps hard due to lack of transition effect in the process of exiting the boot animation and entering the desktop interface of the vehicle-mounted system is solved, and the vehicle use experience of a user is improved.

011: creating a drawing thread;
012: and starting the drawing thread to acquire a starting animation resource package according to a preset storage path.
The processor is used for creating a drawing thread and starting the drawing thread to acquire a starting animation resource package according to a preset storage path.
Specifically, the process of acquiring the boot animation resource package of the vehicle-mounted system includes simultaneously creating a drawing thread of the display part from the thread pool, for example, a plurality of display parts such as a main driving display screen, a secondary driving display screen and/or an instrument display screen can be included in a cabin, and starting the thread, and the code can be expressed as: "newBootanimation (package, loop)". After the drawing thread is started, a startup animation resource package of "bootanimation-0.zip" can be obtained according to a preset storage path.
Thus, the drawing thread can be created and started, and the boot animation resource package is acquired under the preset storage path so as to determine the parameters of the boot animation resource and present the boot animation resource.
Referring to fig. 3 and 4, step 02 includes:
021: loading a boot animation resource package to obtain a description file;
022: and reading the description file to determine drawing parameters and playing parameters.
The processor is used for loading the boot animation resource package to acquire the description file, and reading the description file to determine the drawing parameters and the playing parameters.
Specifically, the obtained boot animation resource package of the vehicle-mounted system may be loaded, as shown in fig. 4, and a description file, such as a text file "desc. Txt", is read in the boot animation resource package to determine drawing parameters and playing parameters of the boot animation resource.
In one example, the acquired description file is decompressed and parsed, and the screen size currently required to be drawn is read as 3280x 580 pixels. The playing parameters include the frame rate of the first animation frame, which may be set to 25 frames per second, and may be appropriately adjusted according to the display efficiency of the screen or the use requirement of the user, and the specific values are not limited herein.
When the first segment resource packet includes two segments, as shown in fig. 4, the two segments may be recorded as a part0 segment and a part1 segment, and in the playing process, the part0 segment may be set to play once according to a preset frame rate, and the part1 segment is circularly played until an exit signal is received. Similarly, the section in the second section resource packet may be recorded as a section 2 section, and set to be played only once under certain conditions. The playing mode of each segment in the first segment resource packet and the second segment resource packet can be changed correspondingly according to the number of segments in the resource packet, and specific playing parameters are not limited herein.
Therefore, the description file in the boot animation resource package can be obtained, and the drawing parameters and the playing parameters of the boot animation resource are determined so as to control the vehicle-mounted system to present the first segment resource package.
Referring to fig. 5, step 03 includes:
031: creating a local window through a drawing thread;
032: setting a local window according to the drawing parameters;
033: and drawing the image resources in the first segment resource package in the local window in sequence according to the playing parameters so as to present the animation effect of the first segment resource package.
The processor is used for creating a local window through the drawing thread, setting the local window according to drawing parameters, and drawing image resources in the first segment resource package in the local window according to playing parameters in sequence to present the animation effect of the first segment resource package.
Specifically, a local window (native surface) can be created through the created drawing thread, and various parameters of the local window are set according to the decompressed and parsed description file, namely, the text file "desc. Txt", drawing parameters. In one example, the Android system independent service "surfeflinger" may be used to set the local window. The local window may provide a rendering region of the image resource. After the setting of the local window is completed, the image resources in the first segment resource package can be drawn in the local window in a certain sequence according to the playing parameters so as to present the animation effect presented by a plurality of multi-frame images with opaque backgrounds in the first segment resource package.
Therefore, the local window can be drawn, parameters of the local window can be set, and multi-frame images with opaque backgrounds in the image resource package can be sequentially played according to the playing parameters, so that the animation effect of the multi-frame images can be presented.
Step 032 includes:
the size of the local window, pixel format and intermediate interface layer properties are set according to the rendering parameters.
The processor is configured to set the size of the local window, the pixel format, and the intermediate interface layer properties according to the rendering parameters.
Specifically, the process of setting the local window according to the drawing parameters includes setting the size, pixel format, and intermediate interface layer properties of the local window. In one example, "readyToRun ()" may be defined to create a local window with wide and high parameters 3280 and 580, respectively, in PIXEL FORMAT pixel_format_transmission. And setting an intermediate interface layer (EGL attribute) attribute of the local window according to the drawing parameters in the "fact. Setting EGL_ALPHA_SIZE to 8; egl_depth_size is set to 16. The size of the local window, pixel format, and intermediate interface layer attribute setup process may vary with the drawing parameters obtained in the boot animation resource package.
In this way, the size, pixel format, and intermediate interface layer properties of the local window can be set according to the rendering parameters, providing an area for rendering and rendering the animation resource package.
Referring to fig. 6, step 033 includes:
0331: setting a background transparency parameter value before drawing image resources of a first segment resource packet of each frame;
0332: synthesizing each drawn frame image with a display background to obtain a first animation frame;
0333: and presenting the first animation frame according to the playing parameters so as to present the animation effect of the first fragment resource package.
The processor is used for setting a transparency parameter value of a display background before drawing the image resource of the first segment resource package of each frame, synthesizing the drawn frame image of each frame with the display background to obtain a first animation frame, and presenting the first animation frame according to the playing parameter to present the animation effect of the first segment resource package.
Specifically, after the local window is created and set, the background transparency parameter value, that is, the opacity value (Alpha), in the color buffer (color buffers) is cleared to make the background completely transparent. And then, drawing a multi-frame image with opaque background in the first segment resource package in a local window with transparent background, displaying each frame of drawn image, and synthesizing with the display background in the local window to obtain a first animation frame. After all the first animation frames are obtained, the first animation frames can be played according to the playing parameters, and the animation effect of the first fragment resource package is presented. In one example, the play parameters include a frame rate of the first animation frame and a play count, which may be set to 25 frames per second, with the clip being played once. The playing parameters can be appropriately adjusted according to the display efficiency of the screen or the use requirement of the user, and specific values are not limited herein.
Therefore, the transparency of the background displayed by the local window can be set, the first animation frame synthesized by each frame of image and the local window is presented according to a certain playing parameter, and finally the animation effect of the multi-frame image with opaque background in the first segment resource package is presented.
Referring to fig. 7, step 04 includes:
041: and in response to receiving an exit signal of the startup animation, sequentially drawing multi-frame images of the second segment resource package on a local window according to the playing parameters so as to present a background fade animation effect of the second segment resource package.
The processor is used for responding to the received exit signal of the startup animation, and sequentially drawing multi-frame images of the second segment resource package on the local window according to the playing parameters so as to present the background fade animation effect of the second segment resource package.
Specifically, the method can respond to the received exit signal of the startup animation, namely after the drawing thread exits the exit signal, the playing of the segments in the first segment resource packet is terminated, and the middle image resources of the second segment resource packet are sequentially drawn in the local window according to the playing parameters in a certain sequence, so as to present the background fade-out animation effect exhibited by the multi-frame images in the second segment resource packet.
Therefore, the playing of the current image resource can be stopped after the received exit signal of the startup animation, and the multi-frame image resource with the background transparency increased in the image resource package is sequentially played according to the playing parameters, so that the animation effect of fading the background of the multi-frame image resource can be presented.
Referring to fig. 8 and 9, step 041 includes:

Specifically, after the local window is created, the specified pixel format parameters are entered, and the background transparency parameters in the middle interface layer attribute, i.e., the size of the opacity value (Alpha), and the buffer depth (z-buffer) are set. Wherein z represents a depth value, the depth of a pixel point represents the distance between the pixel point and the camera in the three-dimensional space, and the larger the depth value is, the farther the pixel point is from the camera, otherwise, the closer the pixel point is from the camera. When each frame of picture is drawn in the local window, parameters of glClearColor () can be modified, for example, depth values of all pixel points are set to be the same value, so that pixel points with sequential differences in drawing time are ensured not to be mutually covered. In addition, in the process of drawing each frame of picture in a certain order, the background transparency parameter, that is, the opacity value (Alpha) in the color buffer (color buffers) is cleared, so that the background is completely transparent.
Further, multi-frame images with increasing background transparency in the second segment resource package are drawn in a local window provided with a transparent background, each frame of drawn images can be displayed, and the images are synthesized with the display background in the local window to obtain a second animation frame. After all the second animation frames are obtained, the second animation frames can be played according to the playing parameters, the background fade-out animation effect that the second fragment resource package is gradually changed from opaque to transparent is presented, and the transparency change among the image frames is required to follow a certain gradient rule in the process. As shown in fig. 9, in one example, the gradient of increasing transparency between image frames of the background fade-out animation effect is 25%, and the exit animation includes 5 second animation frames, which have transparency of 0%, 25%, 50%, 75%, and 100% in order. And after the playing of the 5 second animation frames contained in the background fade-out animation effect is finished, a desktop interface of the vehicle-mounted system is presented, such as an android system desktop. The gradient of transparency change between image frames in the background fade-out animation effect can be changed according to the requirement of a user, and is not limited herein.
In the above example, the play parameters include the frame rate of the second animation frame and the play times, which may be set to 25 frames per second, and the clip is played once. The playing parameters can be appropriately adjusted according to the display efficiency of the screen or the use requirement of the user, and specific values are not limited herein.
Therefore, the background transparency of the local window display can be set, the second animation frame obtained by combining each frame of image with the local window is presented according to a certain playing parameter, and finally, the background fade-out animation effect of the multi-frame images with the background transparency increased in the second segment resource package is presented, so that the use experience of the vehicle-mounted multimedia equipment is improved.
Referring to fig. 10, step 011 includes:
0111: creating an administrator oriented process;
0112: creating a startup animation program process by facing an administrator process;
0113: drawing threads are created by a boot animation program process.
The processor is used for creating an administrator oriented process, creating a boot animation program process through the administrator oriented process and creating a drawing thread through the boot animation program process.
Specifically, after the on-vehicle system is started, the process of creating the drawing thread may include creating a manager-oriented (serviceManager) process, running a "bootanimation" creating a boot animation program process through the manager-oriented process, and finally creating the drawing thread simultaneously from a thread pool including multiple threads through the boot animation program process, where the drawing thread may include drawing a main driving display screen, a sub-screen display screen, and/or an instrument animation, etc.
Therefore, the created manager-oriented process can be used for further creating a startup animation program process, and the drawing process is created through the startup animation program process so as to acquire a startup animation resource package, and finally, the animation effect of the image resource is presented.
