title: How to set AppBarLayout overlaying the content?
body: <p>This is my current XML:</p>
  
  <pre><code>&lt;android.support.design.widget.CoordinatorLayout
      android:layout_width="match_parent"
      android:layout_height="match_parent"&gt;
  
      &lt;android.support.design.widget.AppBarLayout
          android:layout_width="match_parent"
          android:layout_height="wrap_content"&gt;
  
          &lt;include layout="@layout/some_layout" /&gt;
  
      &lt;/android.support.design.widget.AppBarLayout&gt;
  
      &lt;android.support.v7.widget.RecyclerView
          android:id="@+id/recycler_view"
          android:layout_width="match_parent"
          android:layout_height="match_parent"
          app:layout_behavior="@string/appbar_scrolling_view_behavior"/&gt;
  &lt;/android.support.design.widget.CoordinatorLayout&gt;
  </code></pre>
  
  <p>Right now "some_layout" is above the "recycler_view" and scrolls together with it. I want to change it in such way that "some_layout" overlays the recycler view but the scrolling behavior remains (basically both views should be top-aligned when there is no scrolling and "some_layout" should be gone after some scrolling). Is it possible to do with CoordinatorLayout?</p>
