title: State list drawable and disabled state
body: <p>I have a button and I want it to have different background when I set:</p>
  
  <pre><code>android:enabled="false"
  </code></pre>
  
  <p>Here's resource file for background:</p>
  
  <pre><code>&lt;selector xmlns:android="http://schemas.android.com/apk/res/android"&gt;
      &lt;item android:state_pressed="false"
            android:drawable="@drawable/bttn_orange_normal" /&gt; &lt;!-- pressed --&gt;
      &lt;item android:state_pressed="true"
            android:drawable="@drawable/bttn_orange_selected" /&gt; &lt;!-- focused --&gt;
      &lt;item android:state_enabled="false" android:drawable="@drawable/bttn_grey_disabled"/&gt;
      &lt;item android:state_enabled="true" android:drawable="@drawable/bttn_orange_normal"/&gt;
  &lt;/selector&gt;
  </code></pre>
  
  <p>But button still has normal background when it is disabled.
  What am I missing?</p>
