Answer 1

The problem as said above is because RecyclerView as a child or subChild in NestedScrollView measures its height as infinitive when you use WRAP_CONTENT or MATCH_PARENT for height of RecyclerView.

one solution that solved this problem for me was setting the RecyclerView Height to a fixed size. you could set height to a dp value, or you could set it to a pixel value matching devices height if your requirements needs a vertical infinitive RecyclerView.

here is a snippet for setting the recyclerView size in kotlin

    val params = recyclerView.layoutParams
    params.apply {
            width = context.resources.displayMetrics.widthPixels
            height = context.resources.displayMetrics.heightPixels
    }
    recyclerView.layoutParams = params

Answer 2

This case of RecyclerView inside NestedScrollView.

RecyclerView is calling onCreateViewHolder() times equal to your data size.

If data has 200 items, it freezes for onCreateViewHolder() to be called 200 times.

Answer 3
