title: How to properly combine NavigationView and BottomNavigationView
body: <p>I need to use both elements and this is what I have at the moment:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
      xmlns:app="http://schemas.android.com/apk/res-auto"
      android:layout_width="match_parent"
      android:layout_height="match_parent"&gt;
  
      &lt;android.support.v4.widget.DrawerLayout xmlns:tools="http://schemas.android.com/tools"
          android:id="@+id/drawer_layout"
          android:layout_width="match_parent"
          android:layout_height="match_parent"
          android:fitsSystemWindows="true"
          tools:openDrawer="start"&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_main"
              app:menu="@menu/activity_main_drawer" /&gt;
  
      &lt;/android.support.v4.widget.DrawerLayout&gt;
  
      &lt;android.support.design.widget.BottomNavigationView
          android:id="@+id/bottom_navigation_view"
          android:layout_width="match_parent"
          android:layout_height="wrap_content"
          android:layout_alignParentBottom="true"
          android:background="@color/colorAccent"
          app:menu="@menu/menu_bottom" /&gt;
  &lt;/RelativeLayout&gt;
  </code></pre>
  
  <p>My problem here is that the <code>BottomNavigationView</code> is in front of the <code>NavigationView</code>, which should not be the case (I'm talking about the y-index). I also tried using a <code>CoordinatorLayout</code> instead, but then the <code>BottomNavigationView</code> is stuck at the display's top.</p>
