在底部导航视图中组合FAB

Question

我目前正在使用Fab和BottomNavigationView。我想要的是像这样将两者结合在一起

这是我尝试过的代码，看起来不太好

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity">

<android.support.design.widget.FloatingActionButton
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentBottom="true"
    android:layout_centerHorizontal="true"
    android:layout_gravity="center|bottom"
    android:layout_marginBottom="46dp" />

<android.support.design.widget.BottomNavigationView
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_alignParentStart="true"
    android:layout_alignParentBottom="true"
    android:background="@color/colorPrimaryDark"
    app:menu="@menu/nav_items"></android.support.design.widget.BottomNavigationView> </RelativeLayout>

非常感谢任何指导。
