title: How to add a shadow above a view in android
body: <p>I have a view that is to server as a footer title. It is just a view, that you may think of as a button or a textview or a layout (I am open to anything really). Here is the xml</p>
  
  <pre><code>&lt;RelativeLayout&gt;
     &lt;ScrollView &gt;… &lt;/ScrollView&gt; //match parent width and height
     &lt;MyBottomView/&gt; // align parent bottom
   &lt;/RelativeLayout&gt;
  </code></pre>
  
  <p>So as you can see the ScrollView does scroll below MyBottomView. I want to add a top shadow to the MyBottomView so it looks more like Material Design. How might I do that?</p>
