How to refresh Youtube Player View onItemClickListener() in a ListView

Question

I am able to play Youtube videos using cuePlaylist() but I also want to allow user to tap on any of the list item and then I want to refresh YoutubePlayerView with the video user just tapped

I am using cuePlaylist() so getting previous and next buttons as default functionality of Youtube player

So can I refresh YoutubePlayerView with the one I have selected in a ListView?

Here is my complete code, still when I do tap on any of the list item, not getting any change in YoutubePlayerView but able to Log video Id which I just clicked in a ListView...

        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);
        }

    }

Answer 1

You are using the wrong approach here, you don't need to call initialize on YoutubePlayerFragment each time, the first initialization is enough which you done in onCreate method

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

In the initialization listener you implemented in Activity, You should keep the reference of YoutubePlayer in a class level attribute like this

 //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;
    }

}

And use this player attribute to load videos inside onItemClick instead of calling initialize again on YoutubePlayerFragment with new listener

 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();
        }

    }
});
