title: Expandable Listview inside Navigation Drawer not reach bottom of system bar
body: <p>I am trying to implement 'Expandable Listview' inside Navigation Drawer like in the picture below. There are 4 groups, and each group has many children. My problem is, the height of expandable listview is "<strong>short</strong>". How can I make this height reach the bottom of system bar just like a normal navigation drawer using listview with 4 groups data? </p>
  
  <p><img src="https://i.stack.imgur.com/07Zuj.jpg" alt="expandable listview"></p>
  
  <p>this is my main_activity.xml :</p>
  
  <pre><code>&lt;android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
  android:id="@+id/drawer_layout"
  android:layout_width="fill_parent"
  android:layout_height="fill_parent"&gt;
  
  &lt;FrameLayout
      android:id="@+id/content_frame"
      android:layout_width="match_parent"
      android:layout_height="match_parent" &gt;
  &lt;/FrameLayout&gt;
  
  &lt;ExpandableListView
      android:id="@+id/left_drawer"
      android:layout_width="240dp"
      android:layout_height="match_parent"
      android:layout_gravity="start"
      android:choiceMode="singleChoice"
      android:divider="@android:color/black"
      android:dividerHeight="1dp" 
      android:indicatorRight="430dp"/&gt;
  
  &lt;/android.support.v4.widget.DrawerLayout&gt;
  </code></pre>
  
  <p>Any help would be greatly appreciated.
  Environment: Windows 7, ADT, Genymotion.</p>
