我的水平recyclerView包含垂直recyclerview包含文字和媒体recyclerview内的图片和视频。如何获取点击recyclerview horizontal项目的垂直recyclerview项目的位置？
先谢谢，

答案 0 :(得分：1)
尝试以下代码
ReviewMediaRecyclerViewAdapter reviewImagesAdapter = new ReviewMediaRecyclerViewAdapter（reviewsDataSet.get（listPosition）.getUploads（），保持件）;
2.改变内部的recyclelerview适配器，如下所示
ClassReviewsRecyclerViewAdapter.MyViewHolder myViewHolder;
public ReviewMediaRecyclerViewAdapter(ArrayList<Uploads> data,ClassReviewsRecyclerViewAdapter.MyViewHolder myViewHolder) {
this.dataSet = data;
this.myViewHolder = myViewHolder;
}
myViewHolder.getAdapterPosition（）;
实施例： -
((VideoViewHolder)holder).reviewVideo.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Toast.makeText(v.getContext(),myViewHolder.getAdapterPosition()+"", Toast.LENGTH_SHORT).show();
Intent i= new Intent(((VideoViewHolder)holder).reviewVideo.getContext(), VideoPlayerActivity.class);
i.putExtra("VIDEO_URL",dataSet.get(listPosition).getUploadName());
((VideoViewHolder)holder).reviewVideo.getContext().startActivity(i);
}
});
