Android——高德地图简单定位小工具

1.首先需要下载高德的jar包，放在libs目录下

2.LocationUtill.java

 1 import android.content.Context;
 2 
 3 import com.amap.api.location.AMapLocationListener;
 4 import com.amap.api.location.LocationManagerProxy;
 5 import com.amap.api.location.LocationProviderProxy;
 6 
 7 
 8 public class LocationUtil{
 9 
10     //amap
11     private static LocationManagerProxy aMapManager;
12     
13     /**
14      * 开启定位是调用
15      * @param context
16      * @param mAMapLocationListener
17      */
18     public static void startAmap(Context context , AMapLocationListener mAMapLocationListener){
19         aMapManager = LocationManagerProxy.getInstance(context);
20         aMapManager.requestLocationUpdates(LocationProviderProxy.AMapNetwork, 2000, 10, mAMapLocationListener);
21         
22     }
23     /**
24      * 结束定位是调用
25      * @param mAMapLocationListener 根据需要实现这个Listener
26      */
27     public static  void stopAmap(AMapLocationListener mAMapLocationListener) {
28         if (aMapManager != null) {
29             aMapManager.removeUpdates(mAMapLocationListener);
30             aMapManager.destory();
31         }
32         aMapManager = null;
33     }
34     

使用举例：

 MainActivity.java
