我有一个带有CardViews的RecyclerView.我希望每个CardView都有自己的YouTubePlayerFragment.即使它们不能同时处于活动状态,我甚至无法在任何CardView中实例化YouTubePlayerFragment,而是在RecyclerView中实现第一个.当点击卡上应该设置YouTubePlayerFragment的按钮时,它总是在第一张卡上设置,即使我点击了第二张卡.我正在尝试做什么？

以下是代码的相关部分:

CardView XML中片段的持有者:(直接在xml中使用片段给出了二进制XML异常,可能是由于片段中某个片段内的片段)

<FrameLayout
        android:id="@+id/youtube_holder"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_alignParentTop="true"
        android:layout_alignLeft="@+id/layout_video_thumbnail"
        android:layout_alignStart="@+id/layout_video_thumbnail"
        android:layout_alignRight="@+id/layout_video_thumbnail"
        android:layout_alignEnd="@+id/layout_video_thumbnail"
        android:visibility="visible"/>

ViewHolder:

public class VideoViewHolder extends RecyclerView.ViewHolder {

protected FrameLayout containerYouTubePlayer;
protected TextView textViewTitle;
protected ImageView imageViewThumbNail;
protected Button buttonPreview, buttonSet;
protected Context activityContext;

public VideoViewHolder(Context activityContext, View itemView) {
    super(itemView);

    this.activityContext = activityContext;
    containerYouTubePlayer = (FrameLayout) itemView.findViewById(R.id.youtube_holder);
    textViewTitle = (TextView) itemView.findViewById(R.id.textView_title);
    imageViewThumbNail = (ImageView) itemView.findViewById(R.id.imageView_video_thumbnail);
    buttonPreview = (Button) itemView.findViewById(R.id.button_preview);
    buttonSet = (Button) itemView.findViewById(R.id.button_set);
}
}

RecyclerView适配器:

public class VideoCardAdapter extends RecyclerView.Adapter<VideoViewHolder> {
