I think it can be achieved by NestedScrollingChild NestedScrollingParent.
But I can't really understand them.Who can help me out!
Product manager insists on the design.
The ScrollView contains a LinearLayout ,a "TabLayout" and a ViewPager.
The ViewPager contains 2 fragment contains RecyclerView or just only 2 RecyclerView.
When the ScrollView scroll to Bottom , the RecyclerView can scroll to Bottom.
When the RecyclerView scroll to Top , the ScrollView can scroll to Top.
