if want scroll entire layout when 2nd recycler view being scrolled -> can add first recycler view 1st item of second recycler view, in case behave 1 recycler view.
i able implement quick example, code not brilliant, reflecting general idea, pushed github
here main file logic in first recyclerview adapter.
