• 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

      1 package com.example.locationdemo;
      2 
      3 import android.app.Activity;
      4 import android.location.Location;

      6 import android.os.Handler;
      7 import android.os.Message;
      8 import android.view.View;
      9 import android.view.View.OnClickListener;
     10 import android.widget.Button;
     11 import android.widget.TextView;
     12 
     13 import com.amap.api.location.AMapLocation;
     14 import com.amap.api.location.AMapLocationListener;
     15 
     16 public class MainActivity extends Activity {
     17 
     18     private TextView mTextView;
     19     private Button amapBtn;
     20 
     21
