单击内部回收器视图项时如何获取主回收器视图位置的位置

Question

我有一个水平的recyclerView 包含图像和视频，垂直的recyclerview 包含文本和媒体recyclerview。我如何获得单击horizontal recyclerview 项目的垂直recyclerview 项目的位置？

Answer 1

试试下面的代码

1. 将您的主要 recyclerview 持有人传递给内部 recyclerview，例如

ReviewMediaRecyclerViewAdapter reviewImagesAdapter = new ReviewMediaRecyclerViewAdapter(reviewsDataSet.get(listPosition).getUploads(),holder);

2.更改内部recyclerview适配器，如下所示

ClassReviewsRecyclerViewAdapter.MyViewHolder myViewHolder;

public ReviewMediaRecyclerViewAdapter(ArrayList<Uploads> data,ClassReviewsRecyclerViewAdapter.MyViewHolder myViewHolder) {
    this.dataSet = data;
    this.myViewHolder = myViewHolder;

}

1. 现在您可以通过以下代码获取主要 Recyclerview 位置

myViewHolder.getAdapterPosition();

例子：-

((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);
                    }
                });
