title: Drawer Layout in fragment
body: <p>I tried to implement a Drawer Layout in a fragment, however, if I use "android: layout_gravity="start" then my navigational just disappears.The same code works fine if I put it in an activity. 
  And if I try to swipe to the right, it also does not work (you can see it in the image I posted). For me, it looks like I can not swipe to the right and therefor the navigation view can not be opened?</p>
  
  <pre><code>&lt;android.support.v4.widget.DrawerLayout 
     xmlns:android="http://schemas.android.com/apk/res/android"
     android:layout_width="200dp"
     android:layout_height="match_parent"
     xmlns:app="http://schemas.android.com/apk/res-auto"&gt;
  
     &lt;android.support.design.widget.NavigationView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        app:menu="@menu/bottom_navigation"&gt;
      /&gt;
  
  &lt;/android.support.v4.widget.DrawerLayout&gt;
  </code></pre>
