title: selector is in different size than a "normal" image
body: <p>I have a weird problem. When I am doing this:</p>
  
  <pre><code>btnSleeping.setImageDrawable(getResources().getDrawable(
                          R.drawable.selector_sleeping_on));
  </code></pre>
  
  <p>the image is smaller than when I am doing this: <code>btnSleeping.setImageDrawable(getResources().getDrawable(
                              R.drawable.sleeping_on));</code></p>
  
  <p>sleeping_on is an image and selector_sleeping_on is a selector.
  this is my selector:</p>
  
  <pre><code>&lt;selector xmlns:android="http://schemas.android.com/apk/res/android"&gt;
  
  &lt;item android:drawable="@drawable/btn_sleeping_on" android:state_pressed="false"/&gt;
  &lt;item android:drawable="@drawable/btn_sleeping" android:state_pressed="true"/&gt; &lt;!-- default --&gt;
  </code></pre>
  
  <p></p>
  
  <p>I have the sleeping_on and sleeping_off images only in "drawable-xhdpi".
  Why is it that the selector is not appearing the same size as a normal imageViewand how can I make them the same size?</p>
