            </LinearLayout>
        </android.support.design.widget.NavigationView>

    </android.support.v4.widget.DrawerLayout>
</LinearLayout>

and I am trying to scroll on top of the CoordinatorLayout or AppBarLayout(they are both on the top of the screen).

When scrolled on the bottom of the screen (on elements in the last ViewPager, there I have RecyclerView) and click on button "go to top" where I call coordinatorLayout.scrollTo(0,0) it does not work.

So where did I make a mistake, or is there some other way to do this.

Thanks.

Try this:

appBarLayout.setExpanded(true, /*animate=*/true);
