推荐答案

LocationManager mLocManager = (LocationManager)getSystemService(Context.LOCATION_SERVICE);
                LocationListener mLocListener = new MyLocationListener();
                mLocManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, mLocListener);

public class MyLocationListener implements LocationListener{        

        public void onLocationChanged(Location loc) {           
            String message = String.format(
                        "New Location \n Longitude: %1$s \n Latitude: %2$s",
                        loc.getLongitude(), loc.getLatitude()
                );
                Toast.makeText(LbsGeocodingActivity.this, message, Toast.LENGTH_LONG).show();
        }
