I want to scroll smoothly in this activity

Question

Now, my statuses are.

1. Toolbar, ImageView, NestedScrollView, TabLayout and (NestedScrollView and RecyclerView in) ViewPager with PagerFragmentAdapter in Coordinator Layout

2. I want to scroll smoothly in this Activty, with CoordinatorLayout.Behaviors.

3. I think that should have 3 Behaviors with NestedScrollingChild, HeaderBehavior of First NestedScrollView and TabLayoutBehavior of TabLayout and ViewPagerBehavior of ViewPager (with NestedScrollView and RecyclerView).

4. I don't know what how can manage their NestedScrolling.

5. Please give me some advices or solutions.

Thanks :)
