Scroll not working for multiple RecyclerView in BottomSheet

Question

I implemented BottomSheet using the DialogFragment approach. I have a TabLayout and ViewPager in the BottomSheet

Answer 1

I had the same issue, to fix this without the need to override BottomSheetBehavior or the need of an additional library you can to the following: Implement a callback inside your bottom sheet implementation that registers changes of the page.

fun onPageChanged(currentPage: Int) {
   recycler1.isNestedScrollingEnabled = currentPage == 0
   recycler2.isNestedScrollingEnabled = currentPage == 1
   dialog?.findViewById(R.id.design_bottom_sheet)?.requestLayout()
}

In the BottomSheetBehavior implementation in onLayoutChild a lookup for the first child that supports nested scrolling is performed, with this change the lookup is repeated. Not optimal solution but works fine in my case
