Answer 2

全局

private GoogleMap googleMap; 

在OnCreate中

try{ 
     _SetMap(); 
}catch(Exception e){ 
    e.printStackTrace(); 
} 

外OnCreate中，作出新的方法_SetMap

private void _SetMap() { 
    if (googleMap == null) 
     googleMap = ((MapFragment) getFragmentManager().findFragmentById(
       R.id.map)).getMap(); 
    googleMap.setMapType(GoogleMap.MAP_TYPE_NORMAL); 
} 
} 

的Xml

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

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


</LinearLayout> 

清單文件之外的應用程序標記定義

<permission 
    android:name="YourPackageName.permission.MAPS_RECEIVE" 
    android:protectionLevel="signature" /> 
    <uses-permission android:name="YourPackageName.permission.MAPS_RECEIVE" /> 
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /> 
    <uses-permission android:name="android.permission.INTERNET" /> 
    <uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES" /> 
    <uses-feature 
    android:glEsVersion="0x00020000" 
    android:required="true" /> 

並在清單應用程序標記定義

<!-- Google API Key --> 
    <meta-data 
     android:name="com.google.android.maps.v2.API_KEY" 
     android:value="YOURAPIKEY" /> 
    <meta-data 
     android:name="com.google.android.gms.version" 
     android:value="@integer/google_play_services_version" /> 

現在

你必須輸入谷歌播放服務在您的工作從SDK /額外/谷歌
