Как создать панель инструментов на макете googlemaps

Question

Мне интересно, как создать панель инструментов, как показано ниже. Мне было интересно, как создать панель инструментов на самом фрагменте googlemaps, но вместо того, чтобы быть в стороне от фрагмента, мне было интересно, может ли он быть центрирован. Я не хочу отображать вкладки. Я новичок в разработке макетов в андроиде, может кто-то поможет?

<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=".MapsActivity" > 

<fragment 
    android:id="@+id/map" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" 
    class="com.google.android.gms.maps.SupportMapFragment" /> 



</RelativeLayout>

Вы можете попробовать это.

<?xml version="1.0" encoding="utf-8"?> 
<android.support.design.widget.CoordinatorLayout 
    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:fitsSystemWindows="true" 
    tools:context=".MapsActivity"> 

    <android.support.design.widget.AppBarLayout android:layout_height="wrap_content" 
     android:layout_width="match_parent" android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar" 
     android:id="@+id/view"> 

     <android.support.v7.widget.Toolbar android:id="@+id/****" 
      android:layout_width="match_parent" android:layout_height="?attr/actionBarSize" 
      android:background="?attr/colorPrimary" app:popupTheme="@style/ThemeOverlay.AppCompat.Light" /> 

    </android.support.design.widget.AppBarLayout> 



    <fragment xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:map="http://schemas.android.com/apk/res-auto" 
    xmlns:tools="http://schemas.android.com/tools" 
    android:id="@+id/map" 
    android:name="com.google.android.gms.maps.SupportMapFragment" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    tools:context="*****" /> 

</android.support.design.widget.CoordinatorLayout>
