Layer on map

Hello. I was wondering, if it's possible to create a layer above map, so normal map controls could still be used, like zooming with mouse and panning. It could be nice to create a button above map and still use normally map controls. Thanks in advance

Thank You for your answer.

I've been looking that FriendFinder for awhile, but it haven't been any help for me, or I'm just stupid

Might be time to take a break for couple of days, and look again with a "fresh mind". Anyways, if you have straight solution to my problem, I would really appreciate that.

Hello jarmohak,

From your posts i extracted that you want to do sth. like this...

... right

So you will need a class extending Overlay, like this one:

Syntax: [ Download ] [ Hide ]

Using java Syntax Highlighting

    protected class MyLocationOverlay extends Overlay {
        @Override
        public void draw(Canvas canvas, PixelCalculator calculator, boolean shadow) {
          super.draw(canvas, calculator, shadow);
          // Setup our "brush"/"pencil"/ whatever... 
 
          // Draw Circles, Bitmaps whatever...
Parsed in 0.031 seconds,  using GeSHi 1.0.8.4

So we create a new OverlayController from the MapView and set a new MyLocationOverlay to it, like this:

Syntax: [ Download ] [ Hide ]

Using java Syntax Highlighting

          /* With these objects we are capable of
           * drawing graphical stuff on top of the map */
          this.myOverlayController = this.myMapView.createOverlayController();
          MyLocationOverlay myLocationOverlay = new MyLocationOverlay();
          this.myOverlayController.add(myLocationOverlay, true); 
Parsed in 0.031 seconds,  using GeSHi 1.0.8.4

Hope this pushed you into the right direction.

Okay, might be really time for that break. But since I've tried like that wise, all those times map hasn't moved at all. Thank you anyways

Hello jarmohak,

should be moveable, as it also works with the FriendFinder
