Вы можете использовать этот класс для полноэкранного режима Activity, когда состояние и представление навигации не попадают в NavigationView.
У меня возникла та же проблема, и я попробовал комбинацию системных флагов и нашел правильную комбинацию.
// Удаляет прозрачность кровотечения при просмотре навигации
getWindow().addFlags(
WindowManager.LayoutParams.FLAG_FULLSCREEN | WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS);
Вот моя полноэкранная активность.

super.onCreate(savedInstanceState);
if (Build.VERSION.SDK_INT < 14) {
getWindow().requestFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
} else {
hideSystemUI();
