title: Android spinner view
body: <p>Iam new to android development..
  I had a doubt that while using spinner view, we are including an attribute as <strong>android:drawSelectorOnTop="true"</strong> . Can anyone explain me the reason for use of this attribute</p>
  
  <pre><code>             &lt;Spinner android:id="@+id/spinner" 
           android:layout_width="fill_parent" 
           android:layout_height="wrap_content"
           android:drawSelectorOnTop="true"
      /&gt;
  </code></pre>
