一部のYoutubeビデオがRecylerViewに表示される

Question

私はrecylerviewでビデオを表示しようとしています。それはいくつかのものを表示し、また、再生するためにクリックすると、再生中のビデオは表示されませんが、バックグラウンドでは、オーディオを聞くことができます。私はすべてのビデオを表示したい。

} 

@Override

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(Config.YOUTUBE_VIDEO_CODE); 

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

    RecyclerAdapter1 adapter=new RecyclerAdapter1(RecyclerActivity.this);

私はこのようなレイアウトを使用します。

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:id="@+id/parent_relativeLayout"
