Adding a button to Google Maps fragment layout

Question

I want to add a button at the top left corner of the map.

This is my layout:

<?xml version="1.0" encoding="utf-8"?>
<fragment xmlns:android="http://schemas.android.com/apk/res/android"
          android:id="@+id/map"
          android:layout_width="match_parent"
          android:layout_height="match_parent"
          android:name="com.google.android.gms.maps.MapFragment"


          />

I have tried putting the fragment inside a relative layout, but the app crashes.

I have also seen other proposals, but i am not able to make work any of them.

I only need to put a button on the map.

EDITED:

I bet here is your problem:

Caused by: java.lang.ClassCastException: com.google.android.gms.maps.SupportMapFragment cannot be cast to android.app.Fragment

Try declaring SupportMapFragment in your xml instead of MapFragment. And also check that your Activity class extends FragmentActivity
