title: How to change background Color to MaterialButton from android.support.design programmatically
body: <p>I try change color to MaterialButton with this code:</p>
  
  <pre><code>var materialButton = findViewByid(R.id....) as MaterialButton
  materialButton.setBackgroundColor( ContextCompat.getColor(this@MyActivity, R.color.myCustomColor));
  </code></pre>
  
  <p>With a normal Button, it works.
  Anyone have any ideas?</p>
