I try to keep the red layout scrolling so that he hides and the TabLayout stays at the top

How can I change this to achieve this effect?

Instead LinearLayout for offset just use View. Move CircleImageViewFAB(avatar) and View(offset) in CollapsingToolbarLayout after imageView(background) but before Toolbar
