Detailed Description
The technical scheme of the invention will be clearly and completely described below with reference to the accompanying drawings and examples. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without any inventive effort, are intended to be within the scope of the invention.
As shown in fig. 1, in the prior art, theme switching of the in-vehicle infotainment system is mainly completed by traversing a View tree by an application layer and replacing resources such as background, color, text and the like one by one. And the application layer comprises program codes and a plurality of resource files, and the object for which the theme switch is aimed is the resource file. The traversal View tree is subjected to multi-layer selection, and different resource files are different in size, so that loading time is also different, and the problem that part of content which can be perceived by a user is inconsistent in updating easily occurs. Meanwhile, the scheme can only be realized at an application layer, so that theme switching at the application layer does not cause the system level theme to follow switching, and further causes the problem that contents of a status bar and a navigation bar are not switched.
Example 1
Fig. 2 is a flowchart of a method for theme switching in an in-vehicle infotainment system according to an embodiment of the present invention. The embodiment is suitable for the situation that the system level and the application layer theme are switched simultaneously, the method can be executed by a system for switching the theme of the vehicle-mounted information entertainment system, and the system can be realized by software and/or hardware and is generally integrated in computer equipment.
As shown in fig. 2, the technical solution of the embodiment of the present invention specifically includes the following steps:
S01, determining a display request for theme switching according to the demand signal.
Specifically, the demand signals for subject switching include: an internal signal and an external signal. The internal signals are used for acquiring the running mode of the vehicle by monitoring the power parameters of the vehicle in real time. The vehicle operating modes include at least one of a sport mode, an economy mode, and a regular mode. The operating mode of the vehicle is usually already set and cannot be changed. Therefore, internal signals CAN be directly obtained from the ECU of the vehicle by the VEHICLEHAL process and the CARSERVICE process of the Android system through the CAN bus, and the vehicle power mode data is monitored by the process from the registration callback method to the CARSERVICE process. The external signal acquires the external environment signal by monitoring the driving environment change in real time. The external environment signal at least comprises one of day and night change, temperature difference change and weather change. In this embodiment, the external light intensity change is monitored in real time through the light sensor by using the common day and night mode change of the theme switching, and a day and night mode change message is obtained through registering a callback function to CARSERVICE processes, and when the light intensity reaches a certain value, that is, when the day and night mode changes, a display request of the theme switching occurs to switch the theme. The change of the daytime and night mode in the existing mobile phone can be realized only by manual setting; in addition, the daytime and night mode is only useful for a part of application programs, because the part of application programs develop the resource files corresponding to the daytime and night mode, and for application programs which do not develop the resource files of the daytime and night mode, the situation that the theme of the application layer changes along with the theme of the system cannot be realized. Similarly, the signal of the temperature difference change can be obtained in real time by a temperature sensor. Weather changes are complex and require coordinated coordination of multiple sensors, such as temperature sensors, humidity sensors, rain sensors, light sensors, etc.
S02, calling and loading the resource file based on the mapping relation between the preset display request and the resource file, and completing theme switching.
Specifically, a theme resource package is first acquired, where the theme resource package only includes resource files. And, the resource files in one theme resource package include a first file corresponding to one system theme and a second file corresponding to at least one application theme of the system theme. And then configuring the mapping relation between the display request and the resource file, and storing the mapping relation in a file form so as to directly call the corresponding resource file after the display request is acquired.
In connection with fig. 3, the theme pack is constructed by:
Icons, backgrounds, text, colors for display are defined as resource files. And packaging the resource file into a binary form through a Zhuozi source packaging tool to store an application resource index table. This file stores all resource information of the application in the form of binary data. Meanwhile, an Zhuozi the source packaging tool generates a resource file number that maps resource symbol names one-to-one to unique identifiers of the resource files. The application layer is only responsible for providing a unique identifier of a resource when in display, the Android system returns a proper value according to the current configuration (such as the current language, a horizontal screen, a vertical screen, a resolution, and the like), and the code of the scheme is implanted into the dynamic searching process through the design of separating responsibilities, so that the key of innovation of the technical scheme is realized. And finally, configuring a replacement list of the theme resource package so that one system theme corresponds to a plurality of application themes. The list of functions that the theme pack can replace is configured through XML, i.e. one system theme corresponds to at least one application theme, preferably one system theme corresponds to a plurality of application themes. The system theme interface corresponds to, for example, a system interface (navigation bar, status bar) corresponding to an air conditioner control, calculator, or the like. Through the theme resource package configured with the plurality of application themes corresponding to one system theme, the simultaneous replacement of the plurality of application themes during the replacement of one system theme is realized, so that the problem that the system theme and the application theme are not corresponding to each other and perceived by a user does not exist. For example, the problem that the application layer completes the theme switching but the status bar, the navigation bar and the like at the system level are not switched does not occur.
With reference to fig. 4, after the theme resource package is acquired, a mapping relationship between the display request and the resource file needs to be configured. Specifically, the configuration of the theme resource package is analyzed first, and a first file of a system theme is obtained. The configuration XML of the theme resource package is analyzed, and the rule is a unique resource identifier (.s. replaced by @) +switched actual resource identifier (.s. replaced by @) +idmap. Wherein idmap is the identity of the mapping relationship. Illustrating: taking the system interface, the air conditioner control and the calculator as examples, three mapping files are created, respectively:
com@test@theme@demo@com@Android@systemui@idmap；
com@test@theme@demo@com@Android@car@hvac@idmap；
com@test@theme@demo@com@Android@calculator@idmap；
The system comprises a computer, a computer interface, a computer and a computer, wherein com@test@the name@demo@is a unique resource identifier, com@android@system@represents an actual resource identifier of system interface switching, com@android@car@hvac@represents an actual resource identifier of air conditioner control switching, com@android@computer@represents an actual resource identifier of computer switching. And then searching the first files corresponding to the system theme and the second files of all application themes corresponding to the system theme. And establishing a mapping relation between the display requests of the application interface and the system interface and the resource file numbers of the first file and the second file, establishing a corresponding mapping file, and establishing the corresponding mapping file. And finally, locally storing the created mapping file.
In connection with fig. 5, when the theme is switched, the display request sends a request for switching the theme, and the resource file corresponding to the resource file number is called based on the created mapping file. Specifically, a first file is called to replace a resource file of an original system theme. And meanwhile, calling a second file to replace the original resource file of the application program. Then, the system loads the first file by itself and performs interface refreshing to complete the switching of the system theme. When the application program is started, the second file is directly loaded to finish the application theme switching, and resources such as background, color and the like do not need to be replaced one by one in a mode of traversing View through an application layer like the prior art, so that the problem that partial content updating is inconsistent and perceivable by a user can not occur due to different loading time caused by different sizes of the resource files is solved.

Fig. 6 is a schematic structural diagram of a system for theme switching of an in-vehicle infotainment system according to a second embodiment of the present invention. As shown in fig. 6, the embodiment of the present invention includes a first module 10, a second module 20, a third module 30, and a fourth module 40.
Specifically, the first module determines a display request for theme switching according to the demand signal. The third module is used for acquiring the demand signal. The demand signal includes an internal signal and an external signal. The internal signals are used for acquiring the running mode of the vehicle by monitoring the power parameters of the vehicle in real time. The vehicle operating modes include at least one of a sport mode, an economy mode, and a regular mode. The first module includes a CAN bus connected to the vehicle ECU, and obtains the power parameters of the vehicle directly from the vehicle ECU via the CAN bus to determine the vehicle operating mode. The external signal acquires the external environment signal by monitoring the driving environment change in real time. The external environment signal at least comprises one of day and night change, temperature difference change and weather change. The first module further includes a light sensor by which the change in external light intensity is monitored in real time to determine diurnal variation. Similarly, the signal of the temperature difference change can be obtained in real time by a temperature sensor. Weather changes are complex and require coordinated coordination of multiple sensors, such as temperature sensors, humidity sensors, rain sensors, light sensors, etc.
And the second module invokes the resource file and loads the resource file based on the mapping relation between the preconfigured display request and the resource file to finish theme switching. First, a theme resource package is acquired, where the theme resource package only includes resource files. And, the resource files in one theme resource package include a first file corresponding to one system theme and a second file corresponding to at least one application theme of the system theme. And then configuring the mapping relation between the display request and the resource file, and storing the mapping relation in a file form so as to directly call the corresponding resource file after the display request is acquired.
And the fourth module is used for acquiring a theme resource package only containing the resource file and configuring the mapping relation between the display request and the resource file. The resource file includes a first file corresponding to a system theme and a second file corresponding to at least one application theme of the system theme. And configuring and displaying the mapping relation between the request and the resource file, and storing the mapping relation in a file form.
