title: Change color of floating action menu
body: <p>I am using this library for floating action button</p>
  
  <pre><code>https://github.com/futuresimple/android-floating-action-button
  </code></pre>
  
  <p>If anyone is aware about it, we know that we can change the background color of floating action menu with this line in XML:</p>
  
  <pre><code>fab:fab_addButtonColorNormal="@color/floating_action_menu"
  </code></pre>
  
  <p>Is there a way to do so programmatically?</p>
  
  <pre><code>floating&lt;enu.setBackgroundColor(color)
  </code></pre>
  
  <p>Doesn't work......</p>
