Einige Youtube-Videos werden in RecylerView angezeigt

Question

Ich versuche, Videos in recylerview anzuzeigen. Es zeigt einige von ihnen und auch wenn ich klicke um zu spielen, zeigt es nicht das Video an, aber im Hintergrund kann ich das Audio hören. Ich möchte, dass alle Videos angezeigt werden.

ich ein Layout wie folgt verwenden würde:

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:id="@+id/parent_relativeLayout" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" > 
    <android.support.v7.widget.CardView xmlns:android="http://schemas.android.com/apk/res/android" 
     xmlns:card_view="http://schemas.android.com/apk/res-auto" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:clickable="true" 
     android:foreground="@drawable/image_ripple" 
     card_view:cardCornerRadius="5dp" 
     card_view:cardElevation="0dp" 
     android:layout_marginTop="10dp" 
     card_view:cardBackgroundColor="@android:color/black" 
     android:background="@drawable/border_single_pixel" 
     card_view:cardPreventCornerOverlap="false" 
     card_view:cardUseCompatPadding="true"> 


    <com.google.android.youtube.player.YouTubeThumbnailView 
     android:id="@+id/youtube_thumbnail" 
     android:layout_width="match_parent" 
     android:layout_height="250dp" 
     android:scaleType="centerCrop" 
     android:visibility="visible"/> 

    <RelativeLayout android:id="@+id/relativeLayout_over_youtube_thumbnail" 
     android:layout_width="match_parent" 
     android:layout_height="250dp" 
     android:background="@color/color_background_transparent" 
     android:visibility="visible"> 

     <ImageView android:id="@+id/btnYoutube_player" 
      android:layout_width="match_parent" 
      android:layout_height="match_parent" 
      android:scaleType="center" 
      android:src="@mipmap/ic_youtube_play_button"/> 

    </RelativeLayout> 
    </android.support.v7.widget.CardView> 

</RelativeLayout> 

RecyclerView Adapter

public class RecyclerAdapter extends RecyclerView.Adapter<RecyclerAdapter.VideoInfoHolder> { 

    //these ids are the unique id for each video 
    String[] VideoID = {"ndBdf1_oOGA", "7V-fIGMDsmE", "f7ihSQ44WO0"}; 
    Context ctx; 

    public RecyclerAdapter(Context context) { 
     this.ctx = context; 
    } 

    @Override 
    public VideoInfoHolder onCreateViewHolder(ViewGroup parent, int viewType) { 
     View itemView = LayoutInflater.from(parent.getContext()).inflate(R.layout.list_item, parent, false); 
     return new VideoInfoHolder(itemView); 
    } 

    @Override 
    public void onBindViewHolder(final VideoInfoHolder holder, final int position) { 


     final YouTubeThumbnailLoader.OnThumbnailLoadedListener onThumbnailLoadedListener = new YouTubeThumbnailLoader.OnThumbnailLoadedListener(){ 
      @Override 
      public void onThumbnailError(YouTubeThumbnailView youTubeThumbnailView, YouTubeThumbnailLoader.ErrorReason errorReason) { 

      } 

      @Override 
      public void onThumbnailLoaded(YouTubeThumbnailView youTubeThumbnailView, String s) { 
       youTubeThumbnailView.setVisibility(View.VISIBLE); 
       holder.relativeLayoutOverYouTubeThumbnailView.setVisibility(View.VISIBLE); 
      } 
     }; 

     holder.youTubeThumbnailView.initialize(Resources.KEY, new YouTubeThumbnailView.OnInitializedListener() { 
      @Override 
      public void onInitializationSuccess(YouTubeThumbnailView youTubeThumbnailView, YouTubeThumbnailLoader youTubeThumbnailLoader) { 

       youTubeThumbnailLoader.setVideo(VideoID[position]); 
       youTubeThumbnailLoader.setOnThumbnailLoadedListener(onThumbnailLoadedListener); 
      } 

      @Override 
      public void onInitializationFailure(YouTubeThumbnailView youTubeThumbnailView, YouTubeInitializationResult youTubeInitializationResult) { 
       //In case of failure 
      } 
     }); 
    } 

    @Override 
    public int getItemCount() { 
     return VideoID.length; 
    } 

    public class VideoInfoHolder extends RecyclerView.ViewHolder implements View.OnClickListener { 

     protected RelativeLayout relativeLayoutOverYouTubeThumbnailView; 
     YouTubeThumbnailView youTubeThumbnailView; 
     protected ImageView playButton; 

     public VideoInfoHolder(View itemView) { 
      super(itemView); 
      playButton=(ImageView)itemView.findViewById(R.id.btnYoutube_player); 
      playButton.setOnClickListener(this); 
      relativeLayoutOverYouTubeThumbnailView = (RelativeLayout) itemView.findViewById(R.id.relativeLayout_over_youtube_thumbnail); 
      youTubeThumbnailView = (YouTubeThumbnailView) itemView.findViewById(R.id.youtube_thumbnail); 
     } 

     @Override 
     public void onClick(View v) { 

      Intent intent = YouTubeStandalonePlayer.createVideoIntent((Activity) ctx, Resources.KEY, VideoID[getLayoutPosition()]); 
      ctx.startActivity(intent); 
     } 
    } 
}
