Nested RecyclerView. How to prevent parent RecyclerView from getting scrolled while child RecyclerView is scrolling?

Question

I am trying to implement a horizontal recyclerview and each item of the recyclerview will be a vertical recyclerview with a grid layou

Answer 1

I used card view for cells and deactivated parent recycler view scrolling in child adapter with child cell itemView setOnClickListener.

holder.itemView.setOnTouchListener { view, _ ->
    view.parent.parent.requestDisallowInterceptTouchEvent(true)
    false
}

we are calling view.parent.parent because of the fact that itemView is a cell layout and it's parent is our child recyclerView and also, we need to reach child recyclerView's parent to prevent parent recyclerView scrolling.
