  <pre><code>&lt;LinearLayout
      android:layout_width="match_parent"
      android:layout_height="36dp"
      android:background="@drawable/shadow"
      android:layout_gravity="bottom"&gt;
  
      &lt;ImageView
          android:layout_width="wrap_content"
          android:layout_height="wrap_content"
          android:src="@mipmap/ic_add_white_24dp" /&gt;
  &lt;/LinearLayout&gt;
  
  &lt;LinearLayout
      android:id="@+id/bottom_sheet"
      android:layout_width="match_parent"
      android:layout_height="wrap_content"
      android:background="#ff0000"
      app:behavior_hideable="true"
      app:layout_behavior="android.support.design.widget.BottomSheetBehavior"
      android:layout_marginBottom="36dp"&gt;
  
      &lt;Button
          android:layout_width="match_parent"
