#Android 使用User Location获取当前经纬度

Ying-er — Sun, 25 Sep 2011 13:28:00 GMT

step1：声明权限

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

step2：获取LocationManager对象

LocationManager locationManager = (LocationManager)LocationTest.this.getSystemService(Context.LOCATION_SERVICE);

step3：选择LocationProvider，绑定LocationListener对象

locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, new MyLocationListener());

附：MyLocationListener

    private class MyLocationListener implements LocationListener{

        @Override
        public void onLocationChanged(Location location) {
            // TODO Auto-generated method stub
            System.out.println(location.getLatitude());
            System.out.println(location.getLongitude());
        }

        @Override
        public void onProviderDisabled(String provider) {
            // TODO Auto-generated method stub

        }

        @Override
        public void onProviderEnabled(String provider) {
            // TODO Auto-generated method stub

        }

        @Override
        public void onStatusChanged(String provider, int status, Bundle extras) {
            // TODO Auto-generated method stub

        }

    }
