 import android.os.Bundle;

 public class Map2Activity extends MapActivity {

@Override

    setContentView(R.layout.main);
    map = (MapView)findViewById(R.id.mvMain);
    map.setBuiltInZoomControls(true);

清单文件

<uses-sdk android:minSdkVersion="8"/>
<uses-permission android:name="android.permission.INTERNET"/>

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>

  <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>

<application
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name" >
    <uses-library android:name="com.google.android.maps" />

主要的.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" >

<com.google.android.maps.MapView
             android:layout_width="fill_parent"
             android:layout_height="fill_parent"
             android:apiKey="01VR0PIBfyfgbR5DlOlcEBPG9F5WfE7ZBPg"
             android:tag="@+id/mvMain"
             android:enabled="true"
             android:clickable="true" />

</LinearLayout>

我没有使用这两个语句获取地图（强制关闭应用程序）map = (MapView)findViewById(R.id.mvMain); map.setBuiltInZoomControls(true);
如果它必须工作，我需要付出什么？

android:tag="@+id/mvMain"

到

使用它：--main.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">
    <RelativeLayout 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="fill_parent" android:enabled="true"
                android:clickable="true" android:apiKey="0zWsBUUrp7PHyoVnmV5qN5nHhXhZ-VJHhlnjYig" />
            <LinearLayout android:id="@+id/zoom"
                android:layout_width="wrap_content" android:layout_height="wrap_content"
                android:layout_alignParentBottom="true"
                android:layout_centerHorizontal="true" />
        </RelativeLayout>
 </LinearLayout>

在你的活动中使用它——

  LinearLayout zoomLayout = (LinearLayout)findViewById(R.id.zoom);  
    View zoomView = mapView.getZoomControls(); 

    zoomLayout.addView(zoomView, 
        new LinearLayout.LayoutParams(
            LayoutParams.WRAP_CONTENT, 
            LayoutParams.WRAP_CONTENT)); 
    mapView.displayZoomControls(true);

希望它会帮助你..
