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

        CardView cv;
        TextView title;
        TextView description;
        ImageView imageView;


        View_Holder(View itemView) {
            super(itemView);
            cv = (CardView) itemView.findViewById(R.id.cardView);
            title = (TextView) itemView.findViewById(R.id.title);
            description = (TextView) itemView.findViewById(R.id.description);
            imageView = (ImageView) itemView.findViewById(R.id.imageView);

            //added by me
            title.setOnClickListener(this);
            description.setOnClickListener(this);
            imageView.setOnClickListener(this);
        }

        //added by me

        public ImageView getImageView() {
            return imageView;
        }
        public TextView getTitle() {
            return title;
        }
        public TextView getDescription() {
            return description;
        }

        @Override
        public void onClick(View v) {
           // Toast.makeText(get, "CLICK", Toast.LENGTH_SHORT).show();
            Log.i("positon-of-clicked-item", String.valueOf(getAdapterPosition()));
            Log.i("positon-of-clicked-item", String.valueOf(getLayoutPosition()));
            Log.i("positon-of-clicked-item", String.valueOf(this.getTitle()));
            Log.i("positon-of-clicked-item", String.valueOf(this.getDescription()));
           // getLayoutPosition(); //no method like that
        }

只需使用 ViewHolder View 对象即可获取如下所示的详细信息。

@Override
public void onClick(View v) {
   // Toast.makeText(get, "CLICK", Toast.LENGTH_SHORT).show();
    Log.i("positon-of-clicked-item", String.valueOf(getAdapterPosition()));
    Log.i("positon-of-clicked-item", String.valueOf(getLayoutPosition()));
    Log.i("positon-of-clicked-item", String.valueOf(title.getText());
    Log.i("positon-of-clicked-item", String.valueOf(sescription.getText()));
   // getLayoutPosition(); //no method like that
}
