As Figure 1 As shown, the topic management method may include the following operations:

[0090] 101. When receiving a topic configuration request for an object to be configured, determine a target topic type corresponding to the topic configuration request.

[0091] In an embodiment of the present invention, the object to be configured may include an operating system and / or any application; further, the object to be configured may specifically include the UI interface (User Interface) of the operating system and / or any application, which is not limited in the embodiment of the present invention; wherein, the operating system may be the HarmonyOS NEXT system, and the above-mentioned application may be an application program installed in / running in the above-mentioned operating system, which is not limited in the embodiment of the present invention. wherein, the theme configuration request may include a theme switching request or a theme update request; further, the theme update request may be sent by any interface element of the above-mentioned object to be configured to the singleton theme management module, wherein the interface element may include any page of the object to be configured and / or at least one UI component in any page, which is not limited in the embodiment of the present invention.

[0126] 204. Based on the target configuration data, render at least one target configuration component in the object to be configured that matches the target configuration data.

[0127] In the embodiment of the present invention, for other detailed descriptions of step 201 and step 204, please refer to the detailed descriptions of step 101 and step 103 in the first embodiment, which will not be repeated in the embodiment of the present invention.

[0128] It can be seen that the method described in the embodiment of the present invention can, when receiving a theme configuration request for the system and / or application to be configured, first determine the target theme type that needs to be configured, and then call the configuration loading method to load the target configuration data corresponding to the target theme type, and then render the target configuration component based on the target configuration data, so as to achieve efficient loading of the theme configuration data that needs to be switched / updated, thereby improving the theme management efficiency of the HarmonyOS NEXT system while realizing the theme switching function without refreshing the interface, thereby improving the theme switching efficiency of the HarmonyOS NEXT system, and further helping to improve the user's interface browsing experience for the theme that needs to be switched / updated, and helping to improve the user's experience of using the theme management function; further, the singleton theme management module using the singleton mode can avoid repeated instantiation through the singleton mode, thereby significantly reducing the memory required for theme management and further improving the theme management efficiency. In addition, by calling the configuration loading method, the corresponding target configuration information can be read from the configuration mapping table, and then the target configuration data can be loaded based on the target configuration information containing at least one key-value pair, which can improve the reading efficiency of the configuration information corresponding to the target theme type, thereby facilitating further improving the loading efficiency and loading accuracy of the target configuration data required for the target theme type; and, by configuring the mapping table to store the relevant key-value pairs of the configuration data required for the theme type, the number of repeated parsing of the theme configuration file can be reduced, and the reading efficiency of the key-value pairs can be improved, thereby improving the loading efficiency of the target configuration data.

[0129] In an optional embodiment, each target key-value pair can be one of a target color key-value pair, a target image key-value pair, and a target style key-value pair. Optionally, the target color key-value pair can include color value data, the target image key-value pair can include an image storage path, and the target style key-value pair can include style data, all of which are not limited in this embodiment of the present invention. Furthermore, the image storage path can be a storage path stored in a network attached storage device or in another device, all of which are not limited in this embodiment of the present invention.

[0130] Optionally, the theme management framework may also include a resource management module and an image module.

[0131] In this optional embodiment, optionally, loading target configuration data required by the target topic type according to the target configuration information may include the following operations:

[0132] When the target configuration information includes at least one target image key-value pair, for each target image key-value pair, determining whether there is cached image data matching the target image key-value pair in the image cache pool of the theme management framework;

[0133] When it is determined that cached image data matching the target image key-value pair exists in the image cache pool of the theme management framework, the cached image data is loaded into the singleton theme management module as first target image data required by the target theme type;

[0134] When it is determined that there is no cached image data matching the target image key-value pair in the image cache pool of the theme management framework, the second target image data stored in the image storage path indicated by the target image key-value pair is loaded into the image module, and the second target image data is loaded into the singleton theme management module through the resource management module, and the second target image data is cached into the image cache pool.

[0135] Optionally, the second target image data stored in the image storage path indicated by the target image key-value pair may be loaded into the image module by calling a preset image actual loading method, which is not limited in the embodiment of the present invention.

[0136] Optionally, the image cache pool may be set in a singleton theme management module or in other modules of the theme management framework, which is not limited in the embodiment of the present invention.

[0137] Exemplarily, when it is detected that the user has uploaded user-configured image data for the target theme type through any page of the object to be configured, an image loading request is triggered, and the public image acquisition method set by the singleton theme management module is called to request the target image data from the singleton theme management module, thereby calling a pre-set cache call method to determine whether the user-configured image data exists in the image cache pool. If the user-configured image data exists in the image cache pool, the cached image data in the image cache pool that matches the user-configured image data is loaded into the singleton theme management module; otherwise, the user-configured image data can be loaded from the specified path by calling a pre-set image actual loading method. If the loading of the user-configured image data is successful, the user-configured image data is cached in the image cache pool and loaded into the singleton theme management module; further, the target image data loaded into the singleton theme management module is returned to the interface element through the image acquisition method to display the target image data in the target configuration component, which is not limited in the embodiment of the present invention.

[0138] It can be seen that this optional embodiment can first determine whether there is corresponding cached image data in the image cache pool when image data needs to be loaded. If so, the cached image data is directly loaded. Otherwise, the required configured image data is loaded through the image storage path, and the image data is cached to the image cache pool. By adopting a three-level cache structure (memory mapping table-image cache-disk loading), it can improve the loading efficiency of the image data required for switching / updating the theme while reducing the number of IO operations required for loading the configuration data, which is conducive to further improving the theme rendering efficiency, thereby further improving the theme switching efficiency.

[0139] In this optional embodiment, the method may further include the following operations:

[0140] When it is detected that an image loading exception occurs during the process of loading the second target image data stored in the image storage path indicated by the target image key-value pair into the image module, capturing the image loading exception and recording an exception log regarding the image loading exception;

[0141] Perform exception handling operations for image loading exceptions;

[0142] The abnormal image loading method is called to load the preset image data as the target image data into the singleton theme management module; wherein the preset image data can be placeholder image data or application default image data.

[0143] Optionally, the image loading exception may be an invalid image storage path exception or a network exception, or may be other types of exceptions that may occur during the image loading process, which is not limited in the embodiment of the present invention.

[0144] The exception log may record the relevant file identifier of the image loading exception. Specifically, the file identifier may be a file name, which is not limited in the embodiment of the present invention.

[0145] It can be seen that this optional embodiment can also capture and record the exception log of image loading exceptions during the actual loading of image data. It can reduce the possibility of system crashes by capturing exceptions while improving the accuracy of recording image loading exceptions, thereby helping to improve exception handling efficiency and processing accuracy, and thus helping to improve the system's operational reliability; and it can also load pre-prepared default image data to the corresponding component when an image loading exception occurs, which can maintain the continuity of the user's interface browsing experience for the object to be configured, and thus help to improve the user's interface browsing experience for the need to switch / update themes.

[0146] In this optional embodiment, the method may further include the following operations:

[0147] Check whether the number of image caches in the image cache pool is greater than or equal to a preset maximum cache number;

[0148] When it is detected that the number of image caches in the image cache pool is greater than or equal to the maximum cache number, the non-access time of each cached image data in the image cache pool is counted;

[0149] Based on a pre-set cache cleaning strategy and according to a length of time that the cached image data has not been accessed, at least one image data to be cleaned up is determined from all cached image data;

[0150] A cleaning operation is performed on all image data to be cleaned in the image cache pool, so that the number of image caches in the image cache pool after the cleaning operation is performed is less than the maximum cache number.

[0151] Exemplarily, the maximum number of caches may be 60, or other numbers, which is not limited in the embodiment of the present invention.

[0152] Among them, as another optional implementation, it is also possible to detect whether the image cache size of the image cache pool is greater than or equal to a preset maximum cache capacity. When it is detected that the image cache size of the image cache pool is greater than or equal to the maximum cache capacity, a cache cleaning operation as in the above optional implementation may also be performed to make the image cache size of the image cache pool smaller than the maximum cache capacity. This is not limited in the embodiment of the present invention.

[0153] Among them, optionally, the above-mentioned cache cleaning strategy can be an LRU (Least Recently Used) strategy, which is not limited in the embodiment of the present invention; when the cache cleaning strategy is the LRU strategy, at least one cached image data whose non-access time is greater than or equal to a preset time threshold is filtered out from all cached image data as the image data to be cleaned, or a preset number of cached image data with the longest non-access time are filtered out from all cached image data as the image data to be cleaned, which is not limited in the embodiment of the present invention.

[0154] It can be seen that this optional embodiment can also detect whether the number of image caches in the image cache pool exceeds the preset maximum cache number limit. If it has exceeded, the image cache pool is cleaned based on the cache cleaning strategy, so that the cleaned image cache pool can have sufficient cache space to cache the image configuration data that is currently required to be loaded. By setting the maximum cache number limit, the risk of memory leakage can be reduced, which is conducive to improving the reliability of theme management and maintaining the data security and stability of system operation.

[0155] In this optional embodiment, optionally, loading target configuration data required by the target topic type according to the target configuration information may include the following operations:

[0156] When the target configuration information includes at least one target color key-value pair, reading the color value data in each target color key-value pair, and loading the read color value data as the target color data into the singleton theme management module; and / or,

[0157] When the target configuration information includes at least one target style key-value pair, the style data in each target style key-value pair is read, and the read style data is loaded into the singleton theme management module as the target style data.

[0158] Among them, optionally, when the interface element of the object to be configured needs to switch / update the color configuration data, the target color data can be requested by calling the public color acquisition method set by the singleton theme management module, and the target color data can be returned to the interface element through the color acquisition method, thereby performing color configuration on the target configuration component, which is not limited in the embodiment of the present invention.

[0159] It can be seen that this optional embodiment can read the data in the key-value pair as the target configuration data and load it into the singleton theme management module when color data and / or style data needs to be loaded, which can improve the reading efficiency of color configuration data and / or style configuration data, thereby improving the loading efficiency of color configuration data and / or sample color configuration data.

[0160] In another optional embodiment, before calling a preset configuration loading method to read target configuration information corresponding to the target subject type from the configuration mapping table corresponding to the object to be configured, the method may further include the following operations:

[0161] When it is detected that the target theme type is not any historical theme type, a new theme configuration file corresponding to the target theme type is obtained; each historical theme type is a preset theme type or a theme type configured for the object to be configured;

[0162] Add the new theme configuration file to the resource directory corresponding to the object to be configured;

[0163] Parse the newly added theme configuration file and obtain the file parsing result corresponding to the newly added theme configuration file;

[0164] Generate new theme configuration information indicated by the new theme configuration file according to the file parsing result; the new theme configuration information includes at least one new key-value pair;

[0165] Store the newly added topic configuration information in the configuration mapping table.

[0166] Exemplarily, when it is detected that the target theme type is a user-defined theme type newly set or a user-referenced extended theme type, the storage operation of the newly added theme configuration information of this optional embodiment is performed, which is not limited in the embodiment of the present invention.

[0167] Exemplarily, the newly added theme configuration file may be set as a theme configuration file named based on a preset rule, such as "theme3.json", which is not limited in the embodiment of the present invention.

[0168] It can be seen that this optional embodiment can first add the corresponding theme configuration file to the resource directory when it detects that the target theme type is a newly configured theme type, and then parse the theme configuration file to generate the corresponding key-value pairs, and store the generated key-value pairs in the configuration mapping table. It can realize dynamic expansion of theme packages, improve the flexibility of theme configuration, and help improve theme management efficiency and management flexibility; and it is beneficial to obtain configuration information by pre-parsing the configuration file, which can help improve the efficiency of subsequent reading of configuration information, and thus help improve the loading efficiency of theme configuration data.

[0169] In the embodiment of the present invention, for example, please refer to Figure 3 , Figure 3 This is a schematic diagram of the structure of a theme management framework disclosed in an embodiment of the present invention. Figure 3 As shown, the theme management framework can include UgAppTheme (i.e. the singleton theme management module), PreferenceManager (i.e. the persistent storage module), ResourceManager (i.e. the resource management module), Image module (i.e. the image module), UI components / pages (i.e. the interface elements) and theme resource files (i.e. the theme configuration files and / or image data). Furthermore, the interaction between the modules included in the theme management framework can be as follows: Figure 3 The connection relationship of each module in FIG is shown as follows, and is not limited in the embodiment of the present invention.

[0170] Among them, UgAppTheme is used to receive theme configuration requests for UI components / pages, and through interacting with other modules, receive target configuration data efficiently loaded by other modules, and transmit the configuration data requested by UI components / pages to UI components / pages. Furthermore, UgAppTheme may include private properties such as singleton instance (static private), target theme type, configuration mapping table, image cache pool and maximum cache quantity, which are not limited in the embodiment of the present invention; further, UgAppTheme may include public methods such as singleton entry method (for accessing the singleton instance of the singleton theme management module), color acquisition method, theme switching trigger, current theme type acquisition method (for obtaining the above-mentioned target theme type), image acquisition method, actual image loading method and cache cleaning strategy execution method, which are not limited in the embodiment of the present invention.

[0171] In addition, PreferenceManager is used to store the target theme type currently required for configuration, so that the user's selected theme type can be restored when the application is restarted or reloaded; UI components / pages are used to send theme configuration requests to UgAppTheme when the theme type / appearance mode needs to be switched or updated, and receive the target configuration data returned by UgAppTheme, and display / render the target configuration data on the target configuration component; ResourceManager is used to load theme configuration data from theme configuration files / image cache pools / storage paths where theme configuration data is stored; Image modules are used to process and load PixelMap (that is, images that actually need to be read from the image storage path and loaded into the theme management framework), and to manage image cache pools; theme resource files (for example, themeX.json, image data) can be used to record theme configuration data corresponding to the theme type of the object to be configured, which is not limited in the embodiment of the present invention. Furthermore, through modules such as ResourceManager, Image modules, and theme resource files, a three-level cache (configuration mapping table-image cache-disk loading) of the theme management framework is constructed, which can improve the speed of loading configuration resources while reducing the number of IO operations required to load configuration data.

[0185] When it is determined that cached image data matching the target image key-value pair exists in the image cache pool of the theme management framework, the cached image data is loaded into the singleton theme management module as first target image data required by the target theme type;

[0186] When it is determined that there is no cached image data matching the target image key-value pair in the image cache pool of the theme management framework, the second target image data stored in the image storage path indicated by the target image key-value pair is loaded into the image module, and the second target image data is loaded into the singleton theme management module through the resource management module, and the second target image data is cached into the image cache pool.

[0187] It can be seen that the device described in the implementation of this optional embodiment can also first determine whether there is corresponding cached image data in the image cache pool when image data needs to be loaded. If so, the cached image data is directly loaded. Otherwise, the required configured image data is loaded through the image storage path, and the image data is cached to the image cache pool. By adopting a three-level cache structure (memory mapping table-image cache-disk loading), it can improve the loading efficiency of the image data required for switching / updating the theme while reducing the number of IO operations required for loading the configuration data, which is conducive to further improving the theme rendering efficiency, thereby further improving the theme switching efficiency.

If it has exceeded, the image cache pool is cleaned based on the cache cleaning strategy, so that the cleaned image cache pool can have sufficient cache space to cache the image configuration data that is currently required to be loaded. By setting the maximum cache number limit, the risk of memory leakage can be reduced, which is conducive to improving the reliability of theme management and maintaining the data security and stability of system operation.
