java - 如何获取 map 上点击位置的 GeoPosition？

Question

我在 android map Activity 中做一些数学计算，我需要找到用户在 map 上单击的 GeoPoint 的位置。我知道我需要使用 onTouch 事件处理程序。这是它现在的样子:

@Override
public boolean onTouch(View v, MotionEvent event) {

    int action = event.getAction();

    if(action == MotionEvent.ACTION_DOWN)
    {
        GeoPoint pGoal = mapView.getProjection().fromPixels(
                (int) event.getX(),
                (int) event.getY());

        DisplayInfoMessage("The screen has been touched!" + event.getX() + " AND " + event.getY() + "Latitude: "+ pGoal.getLatitudeE6());   // only for displaying test popup

    }
    super.onTouchEvent(event);

    return true;        

}  

虽然它没有做我想要的。至少非常感谢任何帮助或提示!

其实这已经是答案了:

@Override
    public boolean onTouch(View v, MotionEvent event) {

        int action = event.getAction();

        if(action == MotionEvent.ACTION_DOWN)
        {
            GeoPoint pGoal = mapView.getProjection().fromPixels(
                    (int) event.getX(),
                    (int) event.getY());

            DisplayInfoMessage("The screen has been touched!" + event.getX() + " AND " + event.getY() + "Latitude: "+ pGoal.getLatitudeE6());   // only for displaying test popup

        }
        super.onTouchEvent(event);

        return true;        

    }
