本文在上文基础上加入GPS定位功能，实现实时定位，代码如下：

Activity：

package com.home;import android.app.Activity;
import android.content.Context;
import android.graphics.Bitmap;
import android.location.Location;
import android.location.LocationListener;
import android.location.LocationManager;

import android.widget.Toast;import com.baidu.mapapi.BMapManager;
import com.baidu.mapapi.map.MKMapViewListener;
import com.baidu.mapapi.map.MapController;
import com.baidu.mapapi.map.MapPoi;
import com.baidu.mapapi.map.MapView;
import com.baidu.platform.comapi.basestruct.GeoPoint;public class LocationActivity extends Activity {/** 定义LocationManager对象 */private LocationManager locationManager;/** 定义当前Location对象 */private Location currentLocation;/** 显示地图的View */private MapView mMapView = null;/*** 用MapController完成地图控制*/private MapController mMapController = null;/*** MKMapViewListener 用于处理地图事件回调*/MKMapViewListener mMapListener = null;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);/*** 使用地图sdk前需先初始化BMapManager.

}

Application类与上文完全一样。

Manifest里面比上文多加一个如下权限：

 <!-- 使用GPS需要的权限 --><uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

布局文件也和上文完全一样。
