How do I get the Floating button to stay at bottom of the layout?

I'm using coordinator layout, recycler view and floating button. Somehow, the fab button doesn't stay at the bottom of the layout. I would like the button to stay at the bottom even in scrolling. What I do know, is that the fab button takes the bottom position of the last item in recycler view.

list-activity.xml

<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout
    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">

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent">

        <android.support.v7.widget.RecyclerView
            tools:listitem="@layout/activity_sample_05borangb_parent"
            android:id="@+id/recyclerView2"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:scrollbars="vertical"/>

    </RelativeLayout>

    <android.support.design.widget.FloatingActionButton
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:foregroundGravity="bottom"
        android:layout_gravity="bottom|end"/>
