in your onLocationChanged() of your Location Listener you need to write the same code again,

     List<Overlay> mapOverlays = mapView.getOverlays(); 
     mapOverlays.clear() // add this to remove previous
     Drawable drawable = this.getResources().getDrawable(resID); 
     HelloItemizedOverlay itemizedoverlay = new        HelloItemizedOverlay(drawable,this); 
     GeoPoint point = new GeoPoint((int)latd,(int)lond); 
     OverlayItem overlayitem = new OverlayItem(point, name, name); 
     itemizedoverlay.addOverlay(overlayitem); 
     mapOverlays.add(itemizedoverlay);
