Question

我可以使用cuePlaylist()播放Youtube视频，但我也希望允许用户点按任何列表项，然后我想用刚刚点击的视频用户刷新YoutubePlayerView

我正在使用cuePlaylist()，因此将上一个和下一个按钮作为Youtube播放器的默认功能

我可以使用YoutubePlayerView中选择的那个刷新ListView吗？

这是我的完整代码，当我点击任何列表项时，仍然没有YoutubePlayerView中的任何更改，但能够Log我刚刚点击ListView的{{1}}视频ID } ...

        listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {

            strVideoID = flowerList.get(i).getUrl();
            Log.d("url:", strVideoID); // getting particular video id

            youTubePlayerFragment.initialize(API_KEY, new YouTubePlayer.OnInitializedListener() {

                // YouTubeプレーヤーの初期化成功
                @Override
                public void onInitializationSuccess(YouTubePlayer.Provider provider, YouTubePlayer player, boolean wasRestored) {
                    if (!wasRestored) {
                        player.setPlayerStyle(YouTubePlayer.PlayerStyle.DEFAULT);
                        player.loadVideo(strVideoID);
                        player.play();
                    }
                }

                // YouTubeプレーヤーの初期化失敗
                @Override
                public void onInitializationFailure(YouTubePlayer.Provider provider, YouTubeInitializationResult error) {
                    // YouTube error
                    String errorMessage = error.toString();
                    Toast.makeText(MainActivity.this, errorMessage, Toast.LENGTH_LONG).show();
                    Log.d("errorMessage:", errorMessage);
                }
            });

        }
    });

    }

    @Override
    public void onInitializationSuccess(YouTubePlayer.Provider provider, YouTubePlayer youTubePlayer, boolean b) {

        if (!b) {
            youTubePlayer.setPlayerStyle(YouTubePlayer.PlayerStyle.DEFAULT);
            youTubePlayer.cuePlaylist(PLAYLIST_ID);
        }

    }

你在这里使用了错误的方法，你不需要每次都在YoutubePlayerFragment上调用初始化，第一次初始化就足够你在onCreate方法中做了

YouTubePlayerFragment youTubePlayerFragment = YouTubePlayerFragment.newInstance();
    youTubePlayerFragment.initialize(API_KEY, this);

在Activity中实现的初始化侦听器中，您应该将YoutubePlayer的引用保留在类级别属性中，如下所示

 //your class level attribute to keep reference of player
   YouTubePlayer mYoutubePlayer;

@Override
public void onInitializationSuccess(YouTubePlayer.Provider provider, YouTubePlayer youTubePlayer, boolean b) {

    if (!b) {
        youTubePlayer.setPlayerStyle(YouTubePlayer.PlayerStyle.DEFAULT);
        youTubePlayer.cuePlaylist(PLAYLIST_ID);
        //Save reference of initialized player in class level attribute
         mYoutubePlayer = youTubePlayer;
    }

}

并使用此播放器属性在onItemClick中加载视频，而不是使用新侦听器在YoutubePlayerFragment上再次调用初始化

 listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
    @Override
    public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {

        strVideoID = flowerList.get(i).getUrl();
        Log.d("url:", strVideoID); // getting particular video id
        if(mYoutubePlayer!=null){
        mYoutubePlayer.setPlayerStyle(YouTubePlayer.PlayerStyle.DEFAULT);
        mYoutubePlayer.loadVideo(strVideoID);
        mYoutubePlayer.play();
        }

    }
});

步骤播放任何管视频

1在xml文件中创建一个管视图。

<com.google.android.youtube.player.YouTubePlayerView
                android:id="@+id/youtube_view"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:layout_marginBottom="30dp" />

在java文件中

public class MainActivity extends YouTubeBaseActivity implements
            YouTubePlayer.OnInitializedListener {

        private static final int RECOVERY_DIALOG_REQUEST = 1;

        // YouTube player view
        private YouTubePlayerView youTubeView;

        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            requestWindowFeature(Window.FEATURE_NO_TITLE);
            getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
                    WindowManager.LayoutParams.FLAG_FULLSCREEN);

            setContentView(R.layout.activity_main);

            youTubeView = (YouTubePlayerView) findViewById(R.id.youtube_view);

            // Initializing video player with developer key
            youTubeView.initialize(Config.DEVELOPER_KEY, this);

        }

        @Override
        public void onInitializationFailure(YouTubePlayer.Provider provider,
                YouTubeInitializationResult errorReason) {
            if (errorReason.isUserRecoverableError()) {
                errorReason.getErrorDialog(this, RECOVERY_DIALOG_REQUEST).show();
            } else {
                String errorMessage = String.format(
                        getString(R.string.error_player), errorReason.toString());
                Toast.makeText(this, errorMessage, Toast.LENGTH_LONG).show();
            }
        }

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

                // loadVideo() will auto play video
                // Use cueVideo() method, if you don't want to play it automatically
                player.loadVideo(YOUTUBE_VIDEO_CODE);

                // Hiding player controls
                player.setPlayerStyle(PlayerStyle.CHROMELESS);
            }
        }

        @Override
        protected void onActivityResult(int requestCode, int resultCode, Intent data) {
            if (requestCode == RECOVERY_DIALOG_REQUEST) {
                // Retry initialization if user performed a recovery action
                getYouTubePlayerProvider().initialize(DEVELOPER_KEY, this);
            }
        }

        private YouTubePlayer.Provider getYouTubePlayerProvider() {
            return (YouTubePlayerView) findViewById(R.id.youtube_view);
        }

    }
