I have created horizontal recyclerview inside vertical recyclerview like google play store. am able to render items properly but when i add onclicklistener inside horizontal recyclerview am getting only horizontal item position, How to get veritcal recyclerview item position to get the clicked item completely from model class.?

Answer 1

Suppose you have a List<Vertical> for outer recyclerView and a field of vertical list is List<Horizontal> for inner horizontal recyclerview Vertical object should be like this..

public class Vertical {

  //int vertical_Postion;
  List<Horizontal> horizontalList;


}

In recyclerAdapter Vertical (onBindViewHolder()) pass the position to the constructor like this..

   int vertical_position = position; // position you get in the onBindViewHolder
   RecylerAdapterHorizontal horizontal = new RecyclerAdapterHorizontal(context,horizontalList,vertical_postion);
   rv_horizontal.setAdapter(horizontal);

Now you can log the vertical postion in the reycler Adapter horizontal.. it will be constant for one horizontal list

Edit

HorizontalAdapter(Context context,List<Horizontal> horizontal, int mVertPos)

 { 
       this.mVertPos = mVertPos;
       .......
   }  

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

        holder.yourView.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

            Log.e("horizontal pos= " +position);
            Log.e("vert pos= " +mVertPos);

        }
    });
