title: How use two fragment in Android DrawerLayout
body: <p>I try to use Android NavigationDrawe - <a href="http://developer.android.com/training/implementing-navigation/nav-drawer.html" rel="nofollow">http://developer.android.com/training/implementing-navigation/nav-drawer.html</a>
  I have one activity and two fragments.
  My main problem is layout in android.support.v4.widget.DrawerLayout. 
  One fragment use -content_frame and other - content_footer. This element would be in bottom (height - wrap_content). I have tried different variations, but did not work. All examples is with one fragment. What I am doing wrong? thank you<br>
  My main layout file. With this show one fragment.</p>
  
  <pre><code>&lt;android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
  xmlns:tools="http://schemas.android.com/tools"
  android:id="@+id/drawer_layout"
  android:layout_width="match_parent"
  android:layout_height="match_parent" &gt;
  
   &lt;FrameLayout
      android:id="@+id/content_frame"
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      android:layout_gravity="start"
      &gt;    
   &lt;/FrameLayout&gt;
  
   &lt;FrameLayout
      android:id="@+id/content_footer"
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      android:layout_gravity="end"
      &gt;    
   &lt;/FrameLayout&gt;
  
  &lt;ListView
      android:id="@+id/left_drawer"
      android:layout_width="240dp"
      android:layout_height="match_parent"
      android:layout_gravity="start"
      android:background="@color/abs__bright_foreground_disabled_holo_light"
      android:choiceMode="singleChoice"
      android:divider="@android:color/transparent"
      android:dividerHeight="0dp" /&gt; 
   &lt;/android.support.v4.widget.DrawerLayout&gt;  
  </code></pre>
  
  <p>When change to:
      </p>
  
  <pre><code>     &lt;RelativeLayout
          android:id="@+id/content_frame"
          android:layout_width="match_parent"
          android:layout_height="match_parent"
           android:layout_gravity="start"
          &gt;    
       &lt;/RelativeLayout&gt;
  
       &lt;RelativeLayout
          android:id="@+id/content_footer"
          android:layout_width="match_parent"
          android:layout_height="match_parent"
          android:layout_gravity="end"
          &gt;    
       &lt;/RelativeLayout&gt;
   &lt;/FrameLayout&gt; 
  </code></pre>
