title: How to use apply a custom drawable to RadioButton?
body: <p>It looks like we can use the following in a RadioButton:</p>
  
  <pre><code>android:button="@drawable/myCustomStateBackground"
  </code></pre>
  
  <p>but that drawable only occupies the spot where the radio drawable would normally go. Ideally I want my entire button background to be stateful. So when pushed, I want the entire button to look like its stuck in the pressed state. To do that, I was hoping I could do something like:</p>
  
  <pre><code>android:button="null"
  android:background="@drawable/myCustomStateBackground"
  </code></pre>
  
  <p>but then the background drawable doesn't know about push state, like the button attribute does. Is there a way around it?</p>
