title: VideoView - MediaController not showing up
body: <p>I can't get it working... Whenever I touch my video, nothing is happing... Although, I think, the MediaController should be visible...</p>
  
  <p>I currently use following function to play my video:</p>
  
  <pre><code>private void playCachedVideo(final VideoView videoView, final Context c, File f)
  {
      //videoView.setZOrderOnTop(true);        
      videoView.setOnPreparedListener(new OnPreparedListener()
      {
          @Override
          public void onPrepared(MediaPlayer mp) 
          {
              mp.setOnVideoSizeChangedListener(new OnVideoSizeChangedListener() 
              { 
                  @Override
                  public void onVideoSizeChanged(MediaPlayer mp, int width, int height) 
                  {
                      MediaController mediaController = new MediaController(c);
                      mediaController.setMediaPlayer(videoView);
                      mediaController.setAnchorView(videoView);
                      videoView.setMediaController(mediaController);
                  }
              });
          }
      });
      videoView.setVideoURI(Uri.fromFile(f));
      videoView.start();
  }
  </code></pre>
  
  <p>The video plays fine, but I can't get any MediaController to show up...</p>
  
  <p><strong>PS: I'm showing the player in a <code>DialogFragment</code></strong></p>
