Android 4.4 full-screen mode for Progress Dialog

Question

I want my app to run in full-screen mode on devices running Android 4.4.

I have set View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION for my view and it runs in full-screen.

The problem is when I show a ProgressDialog. Then the app exits full-screen mode and the navigation buttons at the bottom are visible agin.

Is it possible for an app to remain in full-screen mode when a progress dialog is shown?

There's a little workaround I found on this topic: How to maintain the Immersive Mode in Dialogs? thanks to Beaver6813's answer (here is the sample code project on GitHub).

So basically, what I did to use this solution on my ProgressDialog is:

• Add two variables to my MainActivity class:

  private ProgressDialog pDialog;    
  private Activity context;
  

• Add the following code in my onCreate method:

  context = this;    
  getWindow().getDecorView().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);
  

• Add the following code where I start my ProgressDialog method:

  pDialog = new ProgressDialog(context);    
  pDialog.getWindow().setFlags(WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE, 
      WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE);    
  pDialog.show();    
  pDialog.getWindow().getDecorView().setSystemUiVisibility(
      context.getWindow().getDecorView().getSystemUiVisibility());    
  pDialog.getWindow().clearFlags(WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE);    
  

That should do the trick!
