title: How to apply shape and selector simultaneously for Button?
body: <p>I have applied a shape for a button like:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  
  &lt;shape xmlns:android="http://schemas.android.com/apk/res/android"
         android:shape="rectangle" &gt;
      &lt;gradient android:startColor="#DD000000" android:endColor="#DD2d2d2d"  android:angle="90"&gt;&lt;/gradient&gt;
      &lt;corners android:radius="15dip"&gt;&lt;/corners&gt;
  
  &lt;/shape&gt;
  </code></pre>
  
  <p>Now I want to use a selector like:</p>
  
  <pre><code>&lt;selector xmlns:android="http://schemas.android.com/apk/res/android"&gt;
  &lt;item android:drawable="@drawable/active"
        android:state_pressed="true" /&gt;
  &lt;item android:drawable="@drawable/passive"/&gt;
  </code></pre>
  
  <p></p>
  
  <p>for this Button as well. Is it possible ...???</p>
