How to add buttons at top of map fragment API v2 layout

Question

I am trying to show maps in android using API v2.
I want UI some thing like this.But whenever I try to add button in layout it does not reflect in output
I am able to get maps without buttons.
I need buttons to integrate with map like below
code for Mylayout.xml:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"

Maybe a simpler solution is to set an overlay in front of your map using FrameLayout or RelativeLayout and treating them as regular buttons in your activity. You should declare your layers in back to front order, e.g., map before buttons. I modified your layout, simplified it a little bit. Try the following layout and see if it works for you:

<FrameLayout 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=".MapActivity" >

    <fragment xmlns:map="http://schemas.android.com/apk/res-auto"
        android:id="@+id/map"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:scrollbars="vertical"  
        class="com.google.android.gms.maps.SupportMapFragment"/>

    <RadioGroup 
        android:id="@+id/radio_group_list_selector"
        android:layout_width="match_parent"
        android:layout_height="48dp"
        android:orientation="horizontal" 
        android:background="#80000000"
        android:padding="4dp" >

        <RadioButton
            android:id="@+id/radioPopular"
            android:layout_width="0dp"
            android:layout_height="match_parent"
            android:text="@string/Popular"
            android:gravity="center_horizontal|center_vertical"
            android:layout_weight="1"
            android:background="@drawable/shape_radiobutton"
            android:textColor="@color/textcolor_radiobutton" />
        <View
            android:id="@+id/VerticalLine"
            android:layout_width="1dip"
            android:layout_height="match_parent"
            android:background="#aaa" />

        <RadioButton
            android:id="@+id/radioAZ"
            android:layout_width="0dp"
            android:layout_height="match_parent"
            android:gravity="center_horizontal|center_vertical"
            android:text="@string/AZ"
            android:layout_weight="1"
            android:background="@drawable/shape_radiobutton2"
            android:textColor="@color/textcolor_radiobutton" />

        <View
            android:id="@+id/VerticalLine"
            android:layout_width="1dip"
            android:layout_height="match_parent"
            android:background="#aaa" />

        <RadioButton
            android:id="@+id/radioCategory"
            android:layout_width="0dp"
            android:layout_height="match_parent"
            android:gravity="center_horizontal|center_vertical"
            android:text="@string/Category"
            android:layout_weight="1"
            android:background="@drawable/shape_radiobutton2"
            android:textColor="@color/textcolor_radiobutton" />
        <View
            android:id="@+id/VerticalLine"
            android:layout_width="1dip"
            android:layout_height="match_parent"
            android:background="#aaa" />

        <RadioButton
            android:id="@+id/radioNearBy"
            android:layout_width="0dp"
            android:layout_height="match_parent"
            android:gravity="center_horizontal|center_vertical"
            android:text="@string/NearBy"

            android:background="@drawable/shape_radiobutton3"
            android:textColor="@color/textcolor_radiobutton" />
    </RadioGroup>
</FrameLayout>

@de Almeida: Exactly what I wanted.Thanks Great Help Buddy.Hope one day I help you as you helped me — sandeep_jagtap, Feb 05 '13 at 17:01
its hiding one gps location symbol(the one on which when we click we camera focus to our gps location) and somehow gps location(blue dot) is missing in map view.. — sandeep_jagtap, Feb 05 '13 at 20:01
@sandeep: MapView does not interact with your GPS. It is only a map. If you want to create a navigation functionality, you have to capture your GPS position yourself and create the buttons, markers and functionality. MapView will, at its best, provide some methods for zooming in and moving map, such as `animateCamera(CameraUpdate update)`. More info in https://developers.google.com/maps/documentation/android/reference/com/google/android/gms/maps/GoogleMap — apenasVB, Feb 06 '13 at 10:11
de Almeida : Thanks a lot for Info ! :) .Since I m new ,dont know stuff in detail. — sandeep_jagtap, Feb 06 '13 at 13:33
This doesn't work for me. I get `Attribute is missing the Android namespace prefix` on `xmlns:map="http://schemas.android.com/apk/res-auto"` — W.K.S, Sep 21 '14 at 10:27
Hi, I know its late. There have been some changes in the API, I guess. While running the above code, it showing "Didn't find class "com.google.android.android.gms.maps.SupportMapFragment" error. I imported the package in the MapsActivity.java. But still I am unable to fix it. Your help required. — Pravinraj Venkatachalam, Oct 04 '16 at 14:06

Button Above The Map

If this is what you want ...simply add button inside the Fragment.

<fragment xmlns:android="http://schemas.android.com/apk/res/android"
    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="com.example.LocationChooser">


    <Button
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="right|top"
        android:text="Demo Button" 
        android:padding="10dp"
        android:layout_marginTop="20dp"
        android:paddingRight="10dp"/>

</fragment>

this works for me! is there anything about this that's bad practice? – yiwei Mar 17 '15 at 23:21
Add a closing tag of would complete this example. Otherwise you get "Error parsing XML: no element found". Thank you for the example. – Homer Wang May 31 '15 at 04:43
when im putting a button tag inside the map fragment, I am having a rendering problems in my xml design view and it's not showing my design view. How's that ? – dens14345 Jul 25 '15 at 05:01
@katwal-Dipak What if we are adding fragment in java code and button in xml? – Tushar Kathuria Dec 26 '15 at 08:14
can you please post the java portion. How am i defining the `map` variable in java? – TWeeKeD Jul 06 '17 at 01:00

Thanks! But in you example you missing this code android:textStyle="bold" android:textColor="#808080" android:alpha="0.5" – NoWar Dec 27 '17 at 06:58
To use that button, you need to set an ID to call it from Java.class like this: android:id="@+id/button1" – Bay Nov 04 '19 at 13:31

extending de Almeida's answer I am editing code little bit here. since previous code was hiding gps location icon I did following way which worked better.

You can use the below code to change the button to Left side.

<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="com.zakasoft.mymap.MapsActivity" >

    <Button
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="left|top"
        android:text="Send"
        android:padding="10dp"
        android:layout_marginTop="20dp"
        android:paddingRight="10dp"/>

</fragment>
