title: View with Solid Background and Top+Bottom Inner Shadows
body: <p>Essentially, I am trying to create the following background:
  <img src="https://i.stack.imgur.com/Njmh5.jpg" alt="enter image description here"></p>
  
  <p>The traditional gradient which use in the drawable that I use for background only supports start color, middle color and end color.</p>
  
  <p>However, as you can see from the mockup, I am trying to create only a slight overlay/shadow at the top and bottom of the shape, with a <code>#50000000</code> color (black with 50% opacity).</p>
