Android：播放 YouTube 视频后如何返回上一个屏幕

Question

单击按钮时，我的应用会播放特定的 YouTube 视频。 观看视频后，我希望 YouTube 视频播放器关闭，应用程序返回上一个屏幕，而不是显示更多建议的视频。 这是我的代码，我该怎么做？

package com.newapp;
import android.os.Bundle;
import android.widget.Toast;
import com.google.android.youtube.player.YouTubeBaseActivity;
import com.google.android.youtube.player.YouTubeInitializationResult;
import com.google.android.youtube.player.YouTubePlayer;
import com.google.android.youtube.player.YouTubePlayer.Provider;
import com.google.android.youtube.player.YouTubePlayerView;

public class Level_1_Training extends YouTubeBaseActivity implements
        YouTubePlayer.OnInitializedListener{

    public static final String API_KEY = "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX";
    public static final String VIDEO_ID = "XXXXXXXXXXXXXXX";

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

        YouTubePlayerView youTubePlayerView = (YouTubePlayerView)findViewById(R.id.youtubeplayerview);
        youTubePlayerView.initialize(API_KEY, this);
    }

    @Override
    public void onInitializationFailure(Provider provider,
                                        YouTubeInitializationResult result) {
        Toast.makeText(getApplicationContext(),
                "onInitializationFailure()",
                Toast.LENGTH_LONG).show();
    }


    @Override
    public void onInitializationSuccess(Provider provider, YouTubePlayer player,
                                        boolean wasRestored) {
        player.setPlayerStyle(YouTubePlayer.PlayerStyle.MINIMAL);
        if (!wasRestored) {

        player.loadVideo(VIDEO_ID);

        }
    }



}

你可以得到 onVideoEnded() 回调。

Youtube API 链接在这里https://developers.google.com/youtube/android/player/reference/com/google/android/youtube/player/YouTubePlayer.PlayerStateChangeListener#onVideoEnded() 您可以在已实现的方法中添加您的逻辑。

@Override
    public void onInitializationSuccess(Provider provider, YouTubePlayer player,
                                        boolean wasRestored) {
        player.setPlayerStyle(YouTubePlayer.PlayerStyle.MINIMAL);
        if (!wasRestored) {
        player.loadVideo(VIDEO_ID);   
        player.setPlayerStateChangeListener(new PlayerStateChangeListener() {
            @Override 
            public void onAdStarted() { }

            @Override 
            public void onError(ErrorReason arg0) { }

            @Override
            public void onLoaded(String arg0) { }

            @Override
            public void onLoading() { }

            @Override 
            public void onVideoEnded() {
    //your logic ,if the previous activity to be called , 
    // you can perform backpress() or intent to call other activity. 
    // also dont forget to remove player in the 
    // onStop() method of the youtube activity.

     }  
            @Override 
            public void onVideoStarted() { }
        });
        }
    }
