 <android.support.design.widget.BottomNavigationView
        android:id="@+id/bottom_navigation"
        android:background="#FF6936C3"
        android:layout_alignParentBottom="true"
        android:layout_width="match_parent"
        android:layout_height="48dp"

<LinearLayout>
  <android.support.design.widget.BottomNavigationView
   android:id="@+id/navigation"
   android:layout_width="match_parent"
   android:layout_height="wrap_content"
   android:layout_gravity="bottom"
   android:background="?android:attr/windowBackground"
   app:menu="@menu/navigation" />
</LinearLayout>

You can define a linear layout and put your bottom navigation in it with its gravity set to bottom. You can find the other details on: https://developer.android.com/reference/android/support/design/widget/BottomNavigationView.html
