Megha.....thanks.
Is there any sample code for handling Overlays in the new SDK?
I previously used OverlayController, which is now gone. I now add my
QuesterOverlay (extends Overlay) as follows:
QuesterOverlay qOverlay = new QuesterOverlay(this,
_mapView);
List<Overlay> overlays = _mapView.getOverlays();
overlays.add(qOverlay);
_mapView.postInvalidate();
Later, when I want qOverlay to (re)draw, I invoke
mapUpdateHandler.sendEmptyMessage(NEED_MAP_UPDATE);
where mapUpdateHandler is defined by:
private Handler mapUpdateHandler
= new Handler() {
public void handleMessage(Message msg) {
switch (msg.what) {
case Quester.NEED_MAP_UPDATE:
// We identified the Message by its
what-ID
if (running) {
// New data loaded; clear the old
overlay and display the new:
_mapView.invalidate();
}
break;
}
super.handleMessage(msg);
}
};
_mapView.invalidate() is clearly called -- the handset screen becomes
a nice light blue, and stays that way.
The code in qOverlay is not invoked -- I have a breakpoint right
inside the draw code (on super):
public synchronized void draw(Canvas canvas, boolean b)
{
super.draw(canvas, mapView, b);
.......etc......
but we never get there.
Hopefully a working example will help me sort it out.
Thanks,
Ken
