title: Floating Action Button on top of Snackbar. How?
body: <p>I'm trying to show my FloatingActionButton on top of the SnackBar but I just can't make it as I have done on other screens. My current layout is this one:</p>
  
  <pre><code>&lt;android.support.v4.widget.DrawerLayout
      android:id="@+id/drawer_layout"
      xmlns:android="http://schemas.android.com/apk/res/android"
      xmlns:app="http://schemas.android.com/apk/res-auto"
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      android:fitsSystemWindows="true"&gt;
  
      &lt;android.support.design.widget.AppBarLayout
          android:layout_width="match_parent"
          android:layout_height="wrap_content"&gt;
  
          &lt;android.support.v7.widget.Toolbar
              android:id="@+id/toolbar"
              android:layout_width="match_parent"
              android:layout_height="wrap_content"
              android:background="?attr/colorPrimary"
              android:elevation="@dimen/toolbar_elevation"
              android:minHeight="?attr/actionBarSize"
              app:popupTheme="@style/AppTheme.ToolbarPopUp"
              app:theme="@style/AppTheme.Toolbar"/&gt;
  
          &lt;android.support.design.widget.TabLayout
              android:id="@+id/sliding_tabs"
              style="@style/Feed.TabLayout"
              android:layout_width="match_parent"
              android:layout_height="wrap_content"
              android:elevation="4dp"/&gt;
  
          &lt;android.support.design.widget.CoordinatorLayout
              android:id="@+id/coordinator_fab"
              android:layout_width="match_parent"
              android:layout_height="match_parent"&gt;
  
              &lt;android.support.v4.view.ViewPager
                  android:id="@+id/view_pager"
                  android:layout_width="match_parent"
                  android:layout_height="match_parent"/&gt;
  
              &lt;android.support.design.widget.FloatingActionButton
                  android:id="@+id/fab"
                  style="@style/FloatingActionButton"
                  android:layout_width="wrap_content"
                  android:layout_height="wrap_content"
                  android:layout_gravity="bottom|end"
                  android:src="@drawable/ic_start"
                  app:backgroundTint="@color/h19_green"
                  app:elevation="6dp"
                  app:pressedTranslationZ="12dp"/&gt;
          &lt;/android.support.design.widget.CoordinatorLayout&gt;
      &lt;/android.support.design.widget.AppBarLayout&gt;
  
      &lt;include layout="@layout/navdrawer"/&gt;
  
  &lt;/android.support.v4.widget.DrawerLayout&gt;
  </code></pre>
  
  <p>And my Snackbar code is this one:</p>
  
  <pre><code>@Override
  public void alertNoInternetConnection() {
     CoordinatorLayout coordinatorLayout =    ButterKnife.findById(getActivity(), R.id.coordinator_fab);
       Snackbar.make(coordinatorLayout, R.string.connection_offline, Snackbar.LENGTH_INDEFINITE).show();
  }
  </code></pre>
  
  <p>How should I reorganize my layout so that when I display the Snackbar, the Floating Action Button hovers above it?</p>
