Sie können FrameLayout verwenden, um acieve, was Sie wollen.

<?xml version="1.0" encoding="utf-8"?> 
<ScrollView 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" 
    android:fillViewport="true"> 
    <LinearLayout 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" 
     android:orientation="vertical" 
     android:weightSum="1"> 
     <android.support.v7.widget.CardView 
      android:layout_width="match_parent" 
      android:layout_height="wrap_content" 
      android:layout_marginTop="@dimen/margin_small"> 
      <fragment 
       android:id="@+id/autocomplete_fragment" 
       android:name="com.google.android.gms.location.places.ui.PlaceAutocompleteFragment" 
       android:layout_width="match_parent" 
       android:layout_height="wrap_content"/> 

     </android.support.v7.widget.CardView> 
     <FrameLayout 
      android:layout_width="match_parent" 
      android:layout_height="match_parent"> 
      <fragment 
       android:id="@+id/map" 
       android:name="com.google.android.gms.maps.SupportMapFragment" 
       android:layout_width="match_parent" 
       android:layout_height="match_parent" 
       tools:context="reminder.locrem.com.locationreminder.MapsActivity" /> 

      <android.support.design.widget.FloatingActionButton 
       android:layout_width="wrap_content" 
       android:layout_height="wrap_content" 
       android:layout_gravity="top|right" 
       android:layout_margin="16dp" 
       android:src="@drawable/done" 
       app:elevation="4dp" 
       app:layout_anchorGravity="bottom|right|end" /> 
     </FrameLayout> 

    </LinearLayout> 
</ScrollView>

Sie müssen nur die android ändern: layout_gravity = "top | ri ght“

<android.support.design.widget.CoordinatorLayout 
    android:id="@+id/main_content" 
    xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:app="http://schemas.android.com/apk/res-auto" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent"> 

      <com.google.android.gms.maps.MapView 
      android:id="@+id/mapView" 
      android:layout_width="match_parent" 
      android:layout_height="match_parent" 
      /> 

      <android.support.design.widget.FloatingActionButton 
       android:layout_width="wrap_content" 
       android:layout_height="wrap_content" 
       android:layout_gravity="top|right" 
       android:layout_margin="16dp" 
       android:src="@drawable/ic_done" 
       app:layout_anchor="@id/lvToDoList" 
       app:layout_anchorGravity="bottom|right|end" /> 
</android.support.design.widget.CoordinatorLayout>
