title: CoordinatorLayout add padding between elements
body: <p>I want to have two FloatingActionButtons in my CoordinatorView. But when I try to add margin to the top FloatingActionButton, It applies from end of the view - It should add space between FloatingActionButtons.
  XML</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;

      android:layout_width="match_parent"
      android:layout_height="match_parent"&gt;
