I have a toolbar in a pager view (tabbed panel with horizontal navigation for navigation), and each tab has its own fragment with recyler_view. Now I want to hide the toolbar when the recyler_view scroll scrolls. In my snippet, I added to scroll-listener and want to call there a method in my activity class to hide the toolbar. A toolbar is created in action. How can I call this method from my fragment? or it would be better to implement this hiding method in my fragment itself. But then, how can I “contact” my toolbar, which is created in action, not in a fragment. I found solutions, but none of them speaks of recyccer_view in fragment and view-pager for tabbed navigation. It would be great if you could help me ...
