null fun requiresLocaleManager() { if (LOCALE_MANAGER ! null) return val localeBinder SystemServiceHelper.getSystemService(locale) LOCALE_MANAGER ILocaleManager.Stub.asInterface(localeBinder) } override fun setApplicationLocales(packageName: String?, locales: LocaleList?) { requiresLocaleManager() val currentUser ActivityManager.getCurrentUser() LOCALE_MANAGER!!.setApplicationLocales(packageName, currentUser, locales, true) } }该架构设计实现了系统级权限的安全访问通过Shizuku提供的Binder机制与Android系统服务进行通信确保了对LocaleManager API的完整控制权。语言环境管理模块LocaleManager类负责处理语言环境的解析和管理通过Java的Locale API获取系统支持的所有语言环境class LocaleManager { val localeList ArrayListLocaleRegion() init { val locales Locale.getAvailableLocales() val localeListMap mutableMapOfString, LocaleRegion() for (locale in locales) { val languageName locale.capDisplayName() val languageTag locale.toLanguageTag() val language locale.getDisplayLanguage(locale).replaceFirstChar { it.uppercaseChar() } val existingLocale localeListMap[language] if (existingLocale ! null) { val singleLocale SingleLocale(languageName, languageTag) existingLocale.locales.add(singleLocale) continue } localeListMap[language] LocaleRegion(language, arrayListOf()) } localeList.addAll(localeListMap.values) localeList.sortBy { it.language } } }应用语言设置界面架构展示LocaleManager模块与系统Locale服务的交互流程包含语言环境解析、分类管理和排序策略依赖注入与组件管理项目采用Hilt进行依赖注入管理Modules.kt文件定义了核心组件的单例模式InstallIn(SingletonComponent::class) Module object Modules { Singleton Provides fun provideLocaleManager(): LocaleManager { return LocaleManager() } }ViewModel架构设计与状态管理主界面状态管理MainScreenVm采用响应式状态管理架构结合Kotlin协程实现异步数据加载HiltViewModel class MainScreenVm Inject constructor( val app: Application ) : ViewModel() { private val _uiState MutableStateFlow(MainScreenState()) val uiState: StateFlowMainScreenState _uiState.asStateFlow() fun fillListOfApps(getAlsoSystemApps: Boolean false) { _uiState.value.listOfApps.clear() viewModelScope.launch(Dispatchers.IO) { val packageList getInstalledPackages(getAlsoSystemApps).map { it } val sortedList packageList.sortedBy { app.packageManager.getLabel(it).lowercase() } _uiState.value.listOfApps.addAll(sortedList) _uiState.update { it.copy(isLoading false) } } } }应用信息状态模型AppInfoState定义了应用语言管理的核心数据模型data class AppInfoState( val appIcon: Drawable? null, val appName: String , val appPackage: String , val currentLanguage: String , val listOfSuggestedLanguages: MutableListSingleLocale mutableStateListOf(), val listOfPinnedLanguages: MutableListSingleLocale mutableStateListOf(), val selectedLanguage: Int -1, val listOfAllLanguages: MutableListLocaleRegion mutableStateListOf(), )快速设置磁贴(QS Tile)实现方案系统集成架构QSTile类实现了Android快速设置磁贴功能提供了实时应用语言切换能力class QSTile : TileService() { private var isLoaded false private val locales mutableListOfSingleLocale() override fun onClick() { if (!this::targetPackage.isInitialized) return UserServiceProvider.run { val currentLocale getApplicationLocales(targetPackage.packageName) val nextLocale getNextSingleLocale(currentLocale) val localeList if (nextLocale.languageTag.isEmpty()) LocaleList() else LocaleList(nextLocale.toLocale()) setApplicationLocales(targetPackage.packageName, localeList) updateTile() } } }系统快捷设置面板集成架构展示QSTile与系统服务的交互流程包含实时语言切换和状态同步机制语言切换算法QSTile实现了循环切换算法确保语言切换的连贯性和用户体验private fun getNextSingleLocale(localeList: LocaleList): SingleLocale { if (locales.isEmpty()) throw Exception(getNextSingleLocale() should be not called with empty MutableListSingleLocale locales) if (localeList.isEmpty) return locales[1] for (i in 0 until locales.size) { val thisLocale locales[i] if (localeList[0].toLanguageTag() thisLocale.languageTag) { if (i locales.size - 1) { return locales.first() } return locales[i 1] } } return locales.first() }系统服务集成与权限管理多服务管理器架构项目实现了对Android系统多个服务的集成访问var ACTIVITY_MANAGER: IActivityManager? null fun requiresActivityManager() { if (ACTIVITY_MANAGER ! null) return val am SystemServiceHelper.getSystemService(activity) ACTIVITY_MANAGER IActivityManager.Stub.asInterface(am) } override fun forceStopPackage(packageName: String?) { requiresActivityManager() val currentUser ActivityManager.getCurrentUser() ACTIVITY_MANAGER!!.forceStopPackage(packageName, currentUser) }运行时任务管理通过ActivityTaskManager获取当前运行应用信息var ACTIVITY_TASK_MANAGER: IActivityTaskManager? null fun requiresActivityTaskManager() { if (ACTIVITY_TASK_MANAGER ! null) return val am SystemServiceHelper.getSystemService(activity_task) ACTIVITY_TASK_MANAGER IActivityTaskManager.Stub.asInterface(am) } override fun getFirstRunningTaskPackage(): String { requiresActivityTaskManager() val runningTask try { ACTIVITY_TASK_MANAGER!!.getTasks(1, false, false, -1).first() } catch (e: NoSuchMethodError) { Log.w( BuildConfig.APPLICATION_ID, getTasks failed, trying again without displayId, error: ${e.stackTraceToString()} ) ACTIVITY_TASK_MANAGER!!.getTasks(1, false, false).first() } return runningTask.topActivity?.packageName ?: }性能优化与兼容性策略语言列表加载优化项目采用延迟加载和缓存策略优化语言列表性能按需加载仅在需要时解析Locale.getAvailableLocales()内存缓存LocaleManager实例采用单例模式避免重复解析异步处理ViewModel使用协程进行异步数据加载版本兼容性处理针对不同Android版本提供兼容性支持override fun setApplicationLocales(packageName: String?, locales: LocaleList?) { requiresLocaleManager() val currentUser ActivityManager.getCurrentUser() if (Build.VERSION.SDK_INT 33 Build.VERSION.RELEASE_OR_CODENAME ! UpsideDownCake) { LOCALE_MANAGER!!.setApplicationLocales(packageName, currentUser, locales) return } LOCALE_MANAGER!!.setApplicationLocales(packageName, currentUser, locales, true) }部署与构建配置Gradle依赖管理项目采用现代Android开发工具链通过libs.versions.toml进行依赖版本管理[versions] shizuku 13.1.1 hilt 2.46 navigation-compose 2.5.3 compose-bom 2023.05.00 [libraries] shizuku-api { module dev.rikka.shizuku:api, version.ref shizuku } hilt-android { module com.google.dagger:hilt-android, version.ref hilt } androidx-navigation-compose { module androidx.navigation:navigation-compose, version.ref navigation-compose }AndroidManifest配置应用声明了必要的系统权限和服务service android:name.QSTile android:exportedtrue android:icondrawable/qs_tile android:labelstring/app_name android:permissionandroid.permission.BIND_QUICK_SETTINGS_TILE meta-data android:nameandroid.service.quicksettings.TOGGLEABLE_TILE android:valuetrue / intent-filter action android:nameandroid.service.quicksettings.action.QS_TILE / /intent-filter /service技术架构总结Language Selector项目通过以下技术架构实现了高性能应用语言管理权限层Shizuku框架提供系统服务访问权限服务层UserService封装LocaleManager、ActivityManager等系统服务业务层LocaleManager处理语言环境ViewModel管理应用状态UI层Jetpack Compose构建现代化用户界面系统集成层QSTile提供快捷设置磁贴功能该架构设计确保了系统级权限的安全访问、语言环境的高效管理以及用户体验的流畅性为Android应用独立语言设置提供了完整的解决方案。【免费下载链接】Language-SelectorLanguage Selector let users select individual app languages (Android 13)项目地址: https://gitcode.com/gh_mirrors/la/Language-Selector创作声明：本文部分内容由AI辅助生成（AIGC），仅供参考
