I have this XML :
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MapFragment">
<include
android:id="@+id/include_toolbar_map"
layout="@layout/toolbar_localizacao"
/>
<android.support.design.widget.FloatingActionButton
android:id="@+id/fab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/ic_localizacao_24dp"
android:theme="@style/FABTheme"
android:layout_alignParentBottom="true"
android:layout_alignParentEnd="true"
android:layout_marginBottom="13dp"
android:layout_marginEnd="13dp"
/>
<com.github.clans.fab.FloatingActionMenu
android:id="@+id/fab_menu"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignEnd="@+id/fab"
android:layout_alignParentBottom="true"
android:layout_marginBottom="73dp">
</com.github.clans.fab.FloatingActionMenu>
<!-- TODO: Update blank fragment layout -->
<fragment xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/map_fragment"
android:name="com.google.android.gms.maps.SupportMapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_alignParentStart="true"
android:layout_alignParentTop="true"
tools:context=".MapActivity" />
But it turns out that fab_menu is behind Fragment (as the image illustrates), and my goal is to get it ahead of Fragment .
