            android:layout_width="match_parent"

CoordinatorLayout and CollapsingToolbarLayout smooth scroll is bug and Google still has not fixed it. :|

remove NestedScrollView. RecyclerView with app:layout_behavior="@string/appbar_scrolling_view_behavior" That's enough and fix.

you can use third party library : smooth-app-bar-layout
