title: Is there a clickable state for a StateListDrawable?
body: <p>I'm building a custom view that can optionally be clickable. I'd like to set a background that indicates the clickable state. Usually, I would do this with an <a href="http://developer.android.com/guide/topics/resources/drawable-resource.html#StateList" rel="nofollow">XML Drawable</a> implemented something like this:</p>
  
  <pre><code>&lt;selector xmlns:android="http://schemas.android.com/apk/res/android"&gt;
      &lt;item android:drawable="@android:color/white" android:state_enabled="false"/&gt;
      &lt;item android:drawable="@drawable/background_white_grey_spinner_pressed" android:state_pressed="true"/&gt;
      &lt;item android:drawable="@drawable/background_white_grey_spinner_normal"/&gt;
  &lt;/selector&gt;
  </code></pre>
  
  <p>Unfortunately, it doesn't look like there's an <code>android:state_clickable</code> or <code>android:state_pressable</code> attribute. This seems like a weird oversight considering there's an <code>android:state_long_pressable</code>. Am I missing something?</p>
