Q:

How to play multiple videos in YouTube Player API? 

I am trying to play a number of videos from YouTube using the YouTube Player API in Android Studio.  I have the Video Id of each videos in different strings with name of video titles.  Now I want the player to play video when each button with video title is clicked. 
@Override
public void onInitializationSuccess(YouTubePlayer. Provider provider, YouTubePlayer player, boolean wasRestored) {
    if (! wasRestored) {
        player.cueVideo("my_video_id_1");
    }
}

Using this method, I don't know how to 'change the string name' when second button is clicked to play the second video in the same player. 
Any answers are highly appreciated! 

A:

First, declare an YouTubePlayer instance and initialize your YouTubePlayerView at onCreate. 
private YouTubePlayer youTubePlayer;

@Override
public void onInitializationSuccess(YouTubePlayer. Provider provider, YouTubePlayer player, boolean wasRestored) {
    if (! wasRestored) {
      if(youTubePlayer == null){
        youTubePlayer = player;
      }
    }
}

Now, provide the video Id corresponding to each button listener. 
    switch (btnId) {
        case R.id.btnOne:
            playVideo("my_video_id_1");
            break;
        case R.id.btnTwo:
            playVideo("my_video_id_2");
            break;
        case R.id.btnThree:
            playVideo("my_video_id_3");
            break;

        default:
            break;
    }

Finally, play the video 
private void playVideo(String videoId){
    if(youTubePlayer ! = null){
        youTubePlayer.loadVideo(videoId);
    }
}
