Android深色模式适配

我们需要再用户设置时候，记录下来，用户的设置，等app再次启动时候，获取之前设置，重新设置

    public static void setThemeMode() {int themeModeType = SpUtils.getThemeModeType();if (themeModeType == 1) {//1：浅色AppCompatDelegate.setDefaultNightMode(AppCompatDelegate.MODE_NIGHT_NO);} else if (themeModeType == 2) {// 2：深色AppCompatDelegate.setDefaultNightMode(AppCompatDelegate.MODE_NIGHT_YES);} else {//跟随系统AppCompatDelegate.setDefaultNightMode(AppCompatDelegate.MODE_NIGHT_FOLLOW_SYSTEM);}}

1、设置单个Activity

   /*** 设置单个Activity 深色、浅色、跟随系统** @param appCompatDelegate Activity AppCompatDelegate* @param themeModeType  0：跟随系统 1：浅色 2：深色*/public static void setThemeModeByActivity(AppCompatDelegate appCompatDelegate, int themeModeType) {if (appCompatDelegate != null) {switch (themeModeType) {case 0:appCompatDelegate.setLocalNightMode(AppCompatDelegate.MODE_NIGHT_FOLLOW_SYSTEM);break;case 1:appCompatDelegate.setLocalNightMode(AppCompatDelegate.MODE_NIGHT_NO);break;case 2:appCompatDelegate.setLocalNightMode(AppCompatDelegate.MODE_NIGHT_YES);break;}}}

2、获取当前Activity是否开启深色

   /*** 通过Activity Resources 获取当前是否开启深色模式** @param object* @return*/public static boolean nightModeByUiResources(Object object) {if (object != null) {if (object instanceof Activity) {int currentNightMode = ((Activity) object).getResources().getConfiguration().uiMode & Configuration.UI_MODE_NIGHT_MASK;return currentNightMode == Configuration.UI_MODE_NIGHT_YES;} else if (object instanceof androidx.fragment.app.Fragment) {int currentNightMode = ((Fragment) object).getResources().getConfiguration().uiMode & Configuration.UI_MODE_NIGHT_MASK;return currentNightMode == Configuration.UI_MODE_NIGHT_YES;} else if (object instanceof android.app.Fragment) {int currentNightMode = ((android.app.Fragment) object).getResources().getConfiguration().uiMode & Configuration.UI_MODE_NIGHT_MASK;return currentNightMode == Configuration.UI_MODE_NIGHT_YES;}}return false;}

3、webView设置

   /*** 设置webView 深色或者浅色模式** @param activity* @param webSetting*/public static void setWebViewNight(Activity activity, WebSettings webSetting) {if (activity == null || webSetting == null) {return;}setWebViewNight(webSetting, nightModeByUiResources(activity));}/*** 设置webView 暗黑模式** @param webSetting* @param nightMode true:深色  false：浅色*/public static void setWebViewNight(WebSettings webSetting, boolean nightMode) {boolean featureSupported = false;try {featureSupported = WebViewFeature.isFeatureSupported(WebViewFeature.FORCE_DARK);} catch (AbstractMethodError e) {e.printStackTrace();}if (featureSupported) {if (nightMode) {//启用 webview 的强制黑暗模式，这意味着 webview 的内容将始终以黑暗主题呈现WebSettingsCompat.setForceDark(webSetting, WebSettingsCompat.FORCE_DARK_ON);} else {//禁用 webview 的强制暗模式，这意味着 webview 的内容将按原样呈现WebSettingsCompat.setForceDark(webSetting, WebSettingsCompat.FORCE_DARK_OFF);}}}

但是h5页面需要做特别判断才能拿到webView深浅模式

@media (prefers-color-scheme: dark) {这里是样式代码}

4、深色浅色切换时候，重启app

  /*** 浅色和深色模式切换，杀死进程，重新打开app** @param activity*/public static void restartApp(Activity activity) {Intent intent = activity.getPackageManager().getLaunchIntentForPackage(activity.getPackageName());if (intent != null) {intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);intent.addFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION);activity.startActivity(intent);android.os.Process.killProcess(android.os.Process.myPid());}}
