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，确切地说...... 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();

    }
}

}

将CurrentLocationGps类放在Main类中（使其成为inner class），这样您就可以访问Main活动中的所有字段。
