Issue with Layout Android

Issue

I want to create a simple interface with a MapView on top and a Button on bottom to refresh said MapView. Both the elements should fill_parent in width, but I want them to not overlap in height. My problem is that my mapview seems to overlap with my Button and hide it. This is my layout.xml:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
     android:orientation="vertical"
     android:layout_width="fill_parent"
     android:layout_height="fill_parent" >

     <com.google.android.maps.MapView
          android:id="@+id/mapview"
          android:layout_width="fill_parent"
          android:layout_height="match_parent"
          android:enabled="true"
          android:clickable="true"
          android:apiKey="my_api_key" /> 

     <Button 
          android:id="@+id/close"
          android:layout_width="fill_parent"
          android:layout_height="fill_parent"
          android:layout_alignParentBottom="true"
          android:text="@string/title_close" /> 
</LinearLayout>

Thanks in advance.

Solution

1. Use a RelativeLayout
2. Place a button as a first child with layout_alignParentBottom="true", make it layout_width="fill_parent" and layout_height="wrap_content"
3. Place MapView second with layout_above="@id/close"
4. Make it layout_width="fill_parent" and layout_height="fill_parent"
