How do I update a map dynamically either as the user moves the map.
I tried to use the below code but the map does not display the data
from server
protected class SitesOverlay extends ItemizedOverlay<OverlayItem> {
private List<OverlayItem> items = new ArrayList<OverlayItem>();
private Drawable marker = null;
public SitesOverlay(Drawable marker) {
super(marker);
this.marker = marker;
populateFriends();
}
@Override
protected OverlayItem createItem(int i) {
return (items.get(i));
}
public synchronized void populateFriends() {
// get it from server
items = //Getting data from server here
super.populate();
}
@Override
public void draw(Canvas canvas, MapView mapView, boolean
shadow) {
super.draw(canvas, mapView, shadow);
boundCenterBottom(marker);
}
@Override
protected boolean onTap(int i) {
showDialog(i);
return (true);
}
@Override
public int size() {
return (items.size());
}
}
