我正在尝试获取用户在谷歌地图上单击的位置（纬度，经度），如何做到这一点？

我试着在网上找到它还没有运气..

关于下面提到的 HelloItemizedOverlay 类，具体实现请参考这个谷歌地图教程。这将在您单击标记的任何位置创建标记，并且还允许用户拖动地图并寻找可以窥视的地方。

class HelloGoogleMaps extends MapActivity
{
@Override
public void onCreate(Bundle savedInstanceState)
{
List<Overlays> mapOverlays = map.getOverlays();
//This is going to be your pointer (you can use whatever image you want as your indicator
final Drawable drawable = this.getResources().getDrawable(R.drawable.indicator);
map.setOnTouchListener(new View.OnTouchListener() {

    @Override
    public boolean onTouch(View v, MotionEvent event) {
        if(event.getAction() == MotionEvent.ACTION_UP)
        {
        HelloItemizedOverlay itemizedoverlay = new HelloItemizedOverlay(drawable, HelloGoogleMaps.this);
        GeoPoint p = mapView.getProjection().fromPixels(
            (int) event.getX(), (int) event.getY());
        String lat = Double.toString(p.getLatitudeE6() / (Math.pow(10,6)));
        String lon = Double.toString(p.getLongitudeE6() / (Math.pow(10,6)));
        OverlayItem overlayitem = new OverlayItem(p, "Title text", "Body Text");
        itemizedoverlay.addOverlay(overlayitem);
        mapOverlays.add(itemizedoverlay);
        map.postInvalidate();
        return true;
        }
    }
});
}
