This method may prevent recycling and should not be used on large data sets.

If you are using RecyclerView inside a ScrollView, just change ScrollView to androidx.core.widget.NestedScrollView. Inside this view there is no need to pack RecyclerView inside a RelativeLayout.

Finally found the solution for this problem.

All you need to do is wrap the RecyclerView in a RelativeLayout. Maybe there are other Views which may also work.
