Android，如何从LocationListener.onlocationchanged（）更改活动字段？

Question

如何从LocationListener.onlocationchanged（）更改活动字段？我想我必须使用一个处理程序，但不知道该怎么做，到底... 我的代码是这样的：

public class Main extends Activity { 
    private Double lat, lon; 
    private LocationManager locationManager; 

    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.main); 

     locationManager = (LocationManager)getSystemService(Context.LOCATION_SERVICE); 
     LocationListener locationListenerGps = new CurrentLocationGps(); 
     locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, locationListenerGps); 
    } 
} 

public class CurrentLocationGps implements LocationListener { 
    @Override 
    public void onLocationChanged(Location loc) { 
     lat = loc.getLatitude(); 
     lon = loc.getLongitude();

    } 
} 

}

放置CurrentLocationGps类主类中（使其成为inner class），这样您就可以访问主要活动中的所有字段。
