Just add this piece of code at your onLocationChanged

@Override
public void onLocationChanged(Location l) {
    // TODO Auto-generated method stub
    overlayList = mapView.getOverlays();
    MyLocationOverlay object = new MyLocationOverlay(yourclass.this, mapView);
    overlayList.add(myLocation); 
    myLocation.enableMyLocation();
}

I'm late to the party, but the reason you are getting the error:

The constructor HelloItemizedOverlay(Drawable, tryanabtry.MyLocationListener) is undefined

is because of your use of this when calling the constructor of HelloItemizedOverlay. In this context, this refers to the instance of MyLocationListener which the code is within, and not an instance of the class tryanabtry.

Replace this line:

itemizedOverlay11= new HelloItemizedOverlay(drawable11,this);

with this:

itemizedOverlay11= new HelloItemizedOverlay(drawable11,tryanabtry.this);

Please also note that by convention Java classes should start with a capital letter, so Tryanabtry instead of tryanabtry.
