title: Display content under toolbar
body: <p>Hello I'm attempting to simply put my content below the toolbar but at the moment when I run my application some of the content is hidden behind it when it should be below it.</p>
  
  <p>I have read up about using a frame layout to attempt to separate it but I have come a little stuck. I'm currently using a basic android studio navigation drawer template provided with the software and was wondering what changes I have to make.</p>
  
  <p>My coordinator layout</p>
  
  <pre><code>&lt;android.support.design.widget.AppBarLayout
      android:layout_width="match_parent"
      android:layout_height="wrap_content"
      android:theme="@style/AppTheme.AppBarOverlay"&gt;
  
      &lt;android.support.v7.widget.Toolbar
          android:id="@+id/toolbar"
          android:layout_width="match_parent"
          android:layout_height="?attr/actionBarSize"
          android:background="?attr/colorPrimary"
          app:popupTheme="@style/AppTheme.PopupOverlay" /&gt;
  
  &lt;/android.support.design.widget.AppBarLayout&gt;
  
  &lt;FrameLayout
      android:id="@+id/fragment_container"
      android:layout_width="match_parent"
      android:layout_height="match_parent"/&gt;
  
  &lt;/android.support.design.widget.CoordinatorLayout&gt;
  </code></pre>

  <p>My drawer layout</p>

  &lt;include

  <p>What changes do I need to make?</p>
