title: Android BottomSheet: Is hiding under the toolbar
body: <p>I tried to use the new bottom sheet from the support library 23.2.0 to have a bottom sheet expand to full screen like suggested in the <a href="https://www.google.com/design/spec/components/bottom-sheets.html#bottom-sheets-behavior" rel="noreferrer">design guidelines</a></p>
  
  <p>This works very good but the bottom sheet goes <em>under my ActionBar</em> and under my tabs.</p>
  
  <p>How is it possible to let the bottom sheet go over the toolbar? My menu is structured like this:</p>
  
  <p>
      </p>
  
  <pre><code>    &lt;android.support.design.widget.AppBarLayout
          android:id="@+id/appbar"
          android:layout_width="match_parent"
          android:layout_height="wrap_content"
          android:paddingTop="@dimen/appbar_padding_top"&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:layout_scrollFlags="scroll|snap|enterAlways"
              app:popupTheme="@style/AppTheme.PopupOverlay"/&gt;
  
          &lt;android.support.design.widget.TabLayout
              android:id="@+id/tabs"
              android:layout_width="match_parent"
              android:layout_height="wrap_content"/&gt;
  
      &lt;/android.support.design.widget.AppBarLayout&gt;
  
      &lt;android.support.v4.view.ViewPager
          android:id="@+id/container"
          android:layout_width="match_parent"
          android:layout_height="match_parent"
          app:layout_behavior="@string/appbar_scrolling_view_behavior"/&gt;
  
      &lt;include
          android:id="@+id/playerLayout"
          layout="@layout/player_main"
          android:layout_width="match_parent"
          android:layout_height="match_parent"
          app:behavior_peekHeight="?attr/actionBarSize"
          app:layout_behavior="@string/bottom_sheet_behavior"
          app:model="@{model}"/&gt;
  
  &lt;/android.support.design.widget.CoordinatorLayout&gt;
