如何在同一活动中使用1个以上的Youtube视频

Question

我正在创建一个应用程序，最近我使用youtube API在我的应用程序中实现了一个活动中的视频，但是1个视频工作正常但我只是想知道如何在同一个视频中使用多个视频以下是我用于单个视频的代码。

public class how2Videos extends YouTubeBaseActivity{
public static final String API_KEY = "xxxxxxxxxxxxxxxx";
public static final String VideoTitanium = "ySQoAiWPXHE";
public static final String VideoNandroid = "36cihz4l-vk";

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_how2_videos);

    /** Initializing YouTube player view **/
    YouTubePlayerView youTubePlayerView = (YouTubePlayerView) findViewById(R.id.Youtube);
    youTubePlayerView.initialize(API_KEY, "ySQoAiWPXHE" );


}

@Override
public void onInitializationSuccess(Provider provider, YouTubePlayer player, boolean wasRestored) {
    /** add listeners to YouTubePlayer instance **/
    /** Start buffering **/
    if (!wasRestored) {
        player.cueVideo(VideoTitanium);
    }
}


@Override
public void onInitializationFailure(YouTubePlayer.Provider provider, YouTubeInitializationResult youTubeInitializationResult) {

    Toast.makeText(this, "Failured to Initialize Your Video.Check if you have a proper internet!", Toast.LENGTH_LONG).show();

}

由于我是初学者，所以我希望得到一些简短的回答，谢谢。
