背景

识别是否全面屏手势场景，然后识别手势指示条是否显示，然后再获取指示条高度

由于全面屏手势是Android9开始出现的，所以验证需要从Android9的机型测到最新的15看时机效果。

是否全面屏手势判断

    public static boolean isGestureNavMode(Context context) {if (null == context) {return false;}if (Build.VERSION.SDK_INT >= 31) {int navMode = Settings.Secure.getInt(context.getContentResolver(), "hide_navigationbar_enable", 0);return navMode == 2 || navMode == 3;} else {return Settings.Secure.getInt(context.getContentResolver(), "navigation_mode", 0) == 2;}}

导航栏高度获取

public static int getNavBarHeightRes(Context context) {int navbarHeight = 0;try {if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.R) {int resourceId = context.getResources().getIdentifier("navigation_bar_height", "dimen", "android");if (resourceId > 0) {navbarHeight = context.getResources().getDimensionPixelSize(resourceId);}} else {Class<?> clazz = Class.forName("com.android.internal.R$dimen");Object obj = clazz.newInstance();Field field = clazz.getField("navigation_bar_height");int height = Integer.parseInt(field.get(obj).toString());navbarHeight = context.getResources().getDimensionPixelSize(height);}} catch (Exception var5) {Log.w(TAG, "getNavBarHeightRes", var5);}Log.d(TAG, "navbarHeight=" + navbarHeight);return navbarHeight;}

通过onApplyWindowInsets监听当前的指示条的可见性

mRootLayout.setOnApplyWindowInsetsListener(new View.OnApplyWindowInsetsListener() {@Overridepublic WindowInsets onApplyWindowInsets(View v, WindowInsets insets) {if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.R) {boolean isNavBarVisible = insets.isVisible(WindowInsets.Type.navigationBars());Log.d(TAG, isNavBarVisible + "  isNavBarVisible  ");}return insets;}});

是否显示状态栏(顺带mark)

这里的代码片段是在检查Activity的窗口是否设置了FLAG_KEEP_SCREEN_ON标志。
true：全屏，当前activity没有显示状态栏 false：有状态栏

int flag = activity.getWindow().getAttributes().flags;
boolean result = (flag & WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON) != 0;
