Android获取经纬度 Android简单获取经纬度的方法

public void getLoc() {
    // 位置
     LocationManager locationManager;
     LocationListener locationListener;
     Location location;
     String contextService = Context.LOCATION_SERVICE;
     String provider;
     double lat;
     double lon;
     locationManager = (LocationManager) getSystemService(contextService);
     Criteria criteria = new Criteria();
     criteria.setAccuracy(Criteria.ACCURACY_FINE);// 高精度
     criteria.setAltitudeRequired(false);// 不要求海拔
     criteria.setBearingRequired(false);// 不要求方位
     criteria.setCostAllowed(true);// 允许有花费
     criteria.setPowerRequirement(Criteria.POWER_LOW);// 低功耗
     // 从可用的位置提供器中，匹配以上标准的最佳提供器
     provider = locationManager.getBestProvider(criteria, true);
     // 获得最后一次变化的位置
     location = locationManager.getLastKnownLocation(provider);
     locationListener = new LocationListener() {
     public void onStatusChanged(String provider, int status,
     Bundle extras) {
     // TODO Auto-generated method stub
     }
     public void onProviderEnabled(String provider) {
     // TODO Auto-generated method stub
     }
     public void onProviderDisabled(String provider) {
     // TODO Auto-generated method stub
     }
     public void onLocationChanged(Location location) {
     lat = location.getLatitude();
     lon = location.getLongitude();
     Log.e("android_lat", String.valueOf(lat));
     Log.e("android_lon", String.valueOf(lon));
     }
     };
     // 监听位置变化，2秒一次，距离10米以上
     locationManager.requestLocationUpdates(provider, 2000, 10,
     locationListener);
