android - 如何在ListView中刷新Youtube Player View onItemClickListener()

我可以使用cuePlaylist()播放Youtube视频，但我也想允许用户点击任何列表项，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

那么，我可以使用在YoutubePlayerView中选择的ListView刷新YoutubePlayerView吗？

这是我的完整代码，仍然是当我点击列表项中的任何一个时，Log并没有发生任何变化，但是能够对ListView视频ID进行更改，而我刚刚单击了ojit_code ...

        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);
        }

    }

最佳答案

您在这里使用了错误的方法，您不需要每次都在YoutubePlayerFragment上调用initialize，您只需在onCreate方法中完成第一个初始化就足够了

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

在Activity中实现的初始化监听器中，应将YoutubePlayer的引用保留在这样的类级别属性中

 //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内加载视频，而不是使用新的监听器在YoutubePlayerFragment上再次调用initialize

 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();
        }

    }
});
