implementation 'com.google.android.youtube:android-player:10.0.1'

<com.google.android.youtube.player.YouTubePlayerView
    android:id="@+id/youtube_player_view"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_marginTop="16dp" />

YouTubePlayerView youtubePlayerView = findViewById(R.id.youtube_player_view);
youtubePlayerView.initialize(API_KEY, new YouTubePlayer.OnInitializedListener() {
    @Override
    public void onInitializationSuccess(YouTubePlayer.Provider provider, YouTubePlayer youTubePlayer, boolean b) {
        // 在初始化成功后，你可以在这里访问YouTubePlayerView
        // 例如，你可以在点击事件中调用YouTubePlayerView的方法
        youTubePlayer.play();
    }

    @Override
    public void onInitializationFailure(YouTubePlayer.Provider provider, YouTubeInitializationResult youTubeInitializationResult) {
        // 处理初始化失败的情况
    }
});

public void onClickButton(View view) {
    YouTubePlayerView youtubePlayerView = findViewById(R.id.youtube_player_view);
    YouTubePlayer youTubePlayer = youtubePlayerView.getYouTubePlayer();
    
    // 播放视频
    youTubePlayer.play();
    
    // 暂停视频
    youTubePlayer.pause();
    
    // 获取视频状态
    YouTubePlayer.PlayerStateChangeListener stateChangeListener = new YouTubePlayer.PlayerStateChangeListener() {
        @Override
        public void onLoading() {
            // 视频正在加载
        }

        @Override
        public void onLoaded(String s) {
            // 视频已加载完成
        }

        @Override
        public void onAdStarted() {
            // 视频广告开始播放
        }

        @Override

            // 视频开始播放
        }

        @Override
        public void onVideoEnded() {
            // 视频播放结束
        }

        @Override
        public void onError(YouTubePlayer.ErrorReason errorReason) {
            // 播放出错
        }
    };
    
    youTubePlayer.setPlayerStateChangeListener(stateChangeListener);
}
