How to get getFirstVisiblePosition() and getChildAt(0) in recyclerview

Question

How to get getFirstVisiblePosition() and getChildAt(0) in recyclerview? Because I want to get position when user click item.

and code in listview is

index = listview.getFirstVisiblePosition();
View v = listview.getChildAt(0);
top = (v == null) ? 0 : (v.getTop() - listview.getPaddingTop());

but I want to use recyclerview.

How to set it?

Both are available via the LayoutManager:

layoutManager.findViewByPosition(position);
layoutManager.findFirstVisibleItemPosition();

if you are using LinearLayoutManager you can use:

int findFirstVisibleItemPosition();

you can use getAdapterPosition() in you view holder. for example:

private class myViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {

       public myViewHolder(View view) {
           super(view);
             view.setOnclickListener(this);
       }

 @Override
public void onClick(View view) {

       int clickedItemPosition = view.getAdapterPosition();

}
   }
