title: Using a coordinatorlayout to collapse a full screen imageview and replace it with viewpager with headers
body: <p>I started playing around with coordinatoralyout and I'm trying to achieve the behavior on the attached image, I want a background image to be on full screen size and upon a scroll I want some textviews to dissapear and some to stick as parts of a viewpager (rather then a toolbarlayout) any guidance on how can I achieve this?</p>
