首先，声明一个 ***Player 实例并在 onCreate 初始化您的 ***PlayerView.

First, declare an ***Player instance and initialize your ***PlayerView at onCreate.

private ***Player ***Player;


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

现在，提供与每个按钮侦听器对应的视频 ID.

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;
    }

最后播放视频

private void playVideo(String videoId){
    if(***Player != null){
        ***Player.loadVideo(videoId);
    }
}
