Android的，如何活动现场从LocationListener.onlocationchanged变化（）？ [英] Android, how to change activity field from LocationListener.onlocationchanged()?

问题描述

我如何从LocationListener.onlocationchanged更改活动场（）？我想我必须使用一个处理程序，但不知道怎么办呢，到底...
我的code是这样的：

How do I change an activity field from LocationListener.onlocationchanged() ? I suppose I have to use a handler, but don't know how to do it, exactly... My code is like this:

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();
>>>>>>>>---<<<<<<<<< How do I pass this values to Main activity fields?
    }
}

}

推荐答案

将主类中CurrentLocationGps类（使它成为一个的内部类），这样你就可以访问主要活动的所有领域。

Place the CurrentLocationGps class inside the Main class (making it an inner class), this way you can access all the fields in Main activity.
