In my layout am using App bar scrolling with overlapping content in Flexible space
I have a buttons list in Nested Scroll view in a horizontal scroll view, I want to stop that horizontal scrollable buttons layout at the top (below of the action bar) when I was scrolling up. How to achieve this, please help?
This the structure of my layout:
