CoordinatorLayout with RecyclerView And Collapsing header
<p>I have a layout like the following:</p>

<p><a href="https://i.stack.imgur.com/H839N.png" rel="noreferrer"><img src="https://i.stack.imgur.com/H839N.png" alt="enter image description here"></a></p>

<p>(Toolbar,
Header View, Text View, RecyclerView)</p>

<p>I need the header to be collapsed when I scrolling recyclerview's items.
So that the view "Choose item" and recyclerview left on the screen.</p>

<p>I saw examples when toolbar is being collapsed, but I need toolbar to be present always.</p>

<p>Which layouts/behavior should I use to get this work?</p>
