Were u able to resolve this problem?
If not, u can always try the following technique that basically
creates a new xparent map overlay that contains an invisible object
that tracks your cellphone location.:
1. create a transparent PNG of same shape/size as your
MyLocationOverlay bitmap;
2. extend the ItemizedOverlay class and override the "draw(Canvas
canvas, MapView mapView, boolean shadow)" method.
In this method, position your xparent PNG at the coordinates as
your location (you can extract your coordinates easily
from your custom MyLocationOverlay class);
3. in the ItemizedOverlay "ontap(int index)" method, respond to the
tap event whenever the correct index is detected. Here
is where you apply whatever actions you want to have performed for
tapping;
4. in your MapActivity "onCreate(Bundle b)" method, create a new
instance of your ItemizedOverlay subclass and append it
to your mapviews' overlays Collection.
**Make sure you first specify the bounds of your Drawable object
BEFORE appending it to the overlays Collection (using
the 'Drawable.setBounds()' method ).
