title: Right drawer marginTop not being set
body: <p>I have a base activity with an layout defined like this:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;android.support.v4.widget.DrawerLayout
      android:id="@+id/drawer_layout"
      xmlns:android="http://schemas.android.com/apk/res/android"
      xmlns:app="http://schemas.android.com/apk/res-auto"
      xmlns:tools="http://schemas.android.com/tools"
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      android:fitsSystemWindows="true"
      tools:openDrawer="end"&gt;
  
      &lt;include
          layout="@layout/app_bar_base"
          android:layout_width="match_parent"
          android:layout_height="match_parent"/&gt;
  
      &lt;android.support.design.widget.NavigationView
          android:id="@+id/nav_view"
          android:layout_width="wrap_content"
          android:layout_height="match_parent"
          android:layout_gravity="start"
          android:fitsSystemWindows="true"
          app:headerLayout="@layout/nav_header_base"
          app:menu="@menu/activity_base_drawer"/&gt;
  
      &lt;FrameLayout
  
          android:id="@+id/right_drawer"
          android:layout_width="match_parent"
          android:layout_height="match_parent"
          android:layout_gravity="end"
          android:layout_marginTop="200dp"/&gt;
  
  &lt;/android.support.v4.widget.DrawerLayout&gt;
  </code></pre>
  
  <p>The <code>include</code> part is where I set my <code>toolbar</code> and have a container that will receive a <code>fragment</code>.</p>
  
  <p>Has you can see by the <code>id</code>, the <code>FrameLayout</code> will act as an <code>right drawer</code>.
  I want that this <code>drawer</code> is placed bellow the <code>toolbar</code>.
  I've tried to add an <code>android:layout_marginTop</code> to the drawer but  with no success (that <code>200dp</code> value is only for tests and the final value will be <code>56dp</code>). When I open the drawer it takes all the screen height (bellow status bar).</p>

  <p>How can I put the <code>frame layout</code> bellow the <code>toolbar</code>?</p>
