<?xml version="1.0" encoding="utf-8"?> <linearlayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" >  <linearlayout     android:layout_width="match_parent"     android:layout_height="match_parent"     android:layout_weight="1.0"     android:orientation="vertical" >       <fragment         xmlns:map="http://schemas.android.com/apk/res-auto"         android:id="@+id/map"         android:name="com.google.android.gms.maps.supportmapfragment"         android:layout_width="match_parent"         android:layout_height="match_parent"/> </linearlayout>  <linearlayout     android:layout_width="match_parent"     android:layout_height="match_parent"     android:layout_weight="1.0"     android:orientation="vertical" >      <listview          android:layout_width="match_parent"         android:layout_height="match_parent"         android:id="@+id/list">               </listview> </linearlayout>  </linearlayout>
