title: Recyclerview with scrolling background
body: <p>I'm trying to create a RecyclerView with scrolling background, like the one shown below. 
  The idea is, as I scroll up/down the viewholders, the background (light-green) image should also move up/down in sync. Any clue as to how to accomplish this?</p>

  <p>Here is my basic RecyclerView configuration</p>
  
  <pre><code>&lt;android.support.v7.widget.RecyclerView
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:id="@+id/recycler_view"
  android:layout_width="match_parent"
  android:layout_height="match_parent"
  android:padding="@dimen/item_margin"
  android:clipToPadding="false"
  android:background="@drawable/ic_light_green_image"/&gt;
  </code></pre>
