Replace the player's UI

Starting from version 5.0.0 it is possible to completely replace the player's UI.

YouTubePlayerView has a new method: View inflateCustomPlayerUI(@LayoutRes int customPlayerUILayoutID).

This method takes in the id of a layout resource. The method returns the View object corresponding to the inflated layout. The default UI of the player gets removed and replaced with the new UI.

After calling this method, the default PlayerUIController won't be available anymore. Calling YouTubePlayerView.getPlayerUIController() will throw an exception.

The user of the library is now required to manage his custom UI with his own code. Meaning: you should write your own PlayerUIController and manage the UI from there. A simple but complete example can be seen here, in the sample app, I recommend you take a few minutes to read it, it should be trivial to understand.

Example (taken from sample app):

View customPlayerUI = youTubePlayerView.inflateCustomPlayerUI(R.layout.custom_player_ui);

youTubePlayerView.initialize(youTubePlayer -> {

  CustomPlayerUIController customPlayerUIController = new CustomPlayerUIController(this, customPlayerUI, youTubePlayer, youTubePlayerView);
  youTubePlayer.addListener(customPlayerUIController);
  youTubePlayerView.addFullScreenListener(customPlayerUIController);

  // ...
}, true);
