CoordinatorLayout inside another CoordinatorLayout

Question

CorodinatorLayout inside another CoordinatorLayout such that scrolling the child-view should also scroll the Parent CoordinatorLayout.

You need to custom your CHILD CoordinatorLayout, let it implement NestedScrollingChild (ori coordinatorlayout didn't implement it) and override some functions to enable dispatching nested scroll event to your PARENT CoordinatorLayout.
