Wie kann ich den Vollbildmodus Immersive beenden?

Question

Ich möchte eine Schaltfläche implementieren, um den immersiven Vollbildmodus zu aktivieren/deaktivieren. Ich benutze diese Methoden, aber die showSystemUI zeigt nur schnell und wieder ausblenden ...

Wie vollständig aus Immersive-Modus beenden?

Meine Methoden:

// This snippet hides the system bars. 
    @SuppressLint("NewApi") 
    private void hideSystemUI() { 
     try{ 
      // Set the IMMERSIVE flag. 
      // Set the content to appear under the system bars so that the content 
      // doesn't resize when the system bars hide and show. 
      mDecorView.setSystemUiVisibility(
        View.SYSTEM_UI_FLAG_LAYOUT_STABLE 
          | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION 
          | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN 
          | View.SYSTEM_UI_FLAG_HIDE_NAVIGATION // hide nav bar 
          | View.SYSTEM_UI_FLAG_FULLSCREEN // hide status bar 
          | View.SYSTEM_UI_FLAG_IMMERSIVE); 
     }catch(Exception e){ 
      getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, 
        WindowManager.LayoutParams.FLAG_FULLSCREEN); 
     } 
    } 

    // This snippet shows the system bars. It does this by removing all the flags 
    // except for the ones that make the content appear under the system bars. 
    @SuppressLint("NewApi") 
    private void showSystemUI() { 
     try{ 
      mDecorView.setSystemUiVisibility(
        View.SYSTEM_UI_FLAG_LAYOUT_STABLE 
          | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION 
          | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN); 
     }catch(Exception e){ 
      getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN); 

      mDecorView.setVisibility(View.GONE); 
      mDecorView.setVisibility(View.VISIBLE); 
      WindowManager.LayoutParams attrs = getWindow().getAttributes(); 
      attrs.flags |= WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN | WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS; 
      getWindow().setAttributes(attrs); 
      mDecorView.setPadding(0, getStatusBarHeight(), 0, 0); 
     } 
    } 

Wie wieder den Inhalt erscheint unter dem System Bars machen?

Aufruf setSystemUiVisibility() mit View.SYSTEM_UI_FLAG_VISIBLE löscht alle Fahnen:

getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_VISIBLE);
