title: Android: Spinner background with a drop down shape
body: <p>Currently I am using this xml for the background of my spinner:</p>
  
  <pre><code>&lt;item android:state_pressed="true" &gt;
      &lt;shape&gt;
          &lt;gradient
              android:startColor="#008000"
              android:endColor="#7FFF00"
              android:angle="270" /&gt;
          &lt;stroke
              android:width="1dp"
              android:color="#A8A8A8" /&gt;
          &lt;corners
              android:radius="6dp" /&gt;
          &lt;padding
              android:left="10dp"
              android:top="10dp"
              android:right="10dp"
              android:bottom="10dp" /&gt;
      &lt;/shape&gt;
  &lt;/item&gt;
  
  &lt;item&gt;        
      &lt;shape&gt;
          &lt;gradient
              android:endColor="#ffc536"
              android:startColor="#ffe9b3"
              android:angle="270" /&gt;
          &lt;stroke
              android:width="1dp"
              android:color="#e4962d" /&gt;
          &lt;corners
              android:radius="6dp" /&gt;
          &lt;padding
              android:left="10dp"
              android:top="10dp"
              android:right="10dp"
              android:bottom="10dp" /&gt;
      &lt;/shape&gt;
  &lt;/item&gt;

  <p>And I like the color and the gradient however there is no indicator that there it is a drop down menu. Is there anyway to add a image or a shape to the right side to indicate a drop down menu? I found this easier then make 9-patch files.</p>
