Get a MapActivity from a MapView

Hi,

I would know how to get the current Activity ?
I have a MapActivity which displays a MapView which calls a method which extends Overlay, and I would get the MapActivity in the MapView and in the Overlay.

Thanks for reply

Hello nono,

I use the MapActivity (here DDMap, which extends MapActivity) in my Overlay, by passing it to the Constructor of the Overlay, like this:

Syntax: [ Download ] [ Hide ]

Using java Syntax Highlighting

public MyMapDrivingDirectionsOverlay(final DDMap aMapAct, final UnitSystem aUS) {
 
   //...
 
}
Parsed in 0.030 seconds,  using GeSHi 1.0.8.4

where adding the Overlay works like this (inside the DDMap-Class):

Syntax: [ Download ] [ Hide ]

Using java Syntax Highlighting

                /* Add a new instance of our fancy Overlay-Class to the MapView. */
 
                this.mOverlayController.add(new MyMapDrivingDirectionsOverlay(this, this.mUnitSystem), true);
Parsed in 0.030 seconds,  using GeSHi 1.0.8.4

Hope I could help you.

Regards,
plusminus

thanks for your reply plusminus,

but I don't call the constructor of the overlay in my MapActivity, I call this in my MapView, so I can retrieve the MapView in my Overlay, but I want to retrieve my MapActivity in my MapView and in my Overlay...
and I can't pass my mapActivity to the constructor of my MapView because I don't use a constructor, I use setContentView() to call my mapView in my mapActivity like this :

Syntax: [ Download ] [ Hide ]

Using java Syntax Highlighting

public class Map extends MapActivity {
 
        private MapLocationViewer mapView;
 
    public void onCreate(Bundle icicle) {
 
        super.onCreate(icicle);
 
        setContentView(R.layout.map);
 
        mapView = (MapLocationViewer)this.findViewById(R.id.map_location_viewer);
 
}
 
}
Parsed in 0.035 seconds,  using GeSHi 1.0.8.4

have you a solution for that ?
