Answer

This should work! use

android:layout_alignParentRight="true"
android:layout_alignParentBottom="true"

.

<android.support.design.widget.FloatingActionButton
                android:layout_alignParent="true"
                android:layout_alignParentRight="true"
                android:layout_alignParentBottom="true"
                android:id="@+id/fab"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_gravity="right"
                android:layout_margin="@dimen/fab_margin"
                app:srcCompat="@drawable/ic_directions_car_white_48dp"
                app:layout_anchorGravity="bottom|right" />
