title: How to disable scrolling of AppBarLayout in CoordinatorLayout?
body: <p>I have <code>MapFragment</code> with parallax effect inside <code>AppBarLayout</code>:</p>
  
  <p><a href="https://i.stack.imgur.com/buDnS.png" rel="noreferrer"><img src="https://i.stack.imgur.com/buDnS.png" alt="enter image description here"></a></p>
  
  <p>I want to disable scrolling on <code>AppBarLayout</code>, because it is not possible to move across map, since touch evenys on the map are always handled as scroll events. 
  I would like to handle collapsing of <code>AppBarLayout</code> by scrolling <code>RecyclerView</code> only, which is on the bottom of the screen.</p>
  
  <p>This is my xml:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
