It is possible to specify/reduce the onTap area of the items on a mapview?

Issue

I have a mapview, with itemizedoverlay, like on Android developers example. But now I have a problem. When the user presses 1 or 2 cm out of the 32x32 image of the item on the map, the dialog of the item opens. I don't want that. I want to reduce the "press" area of the item to the 32x32 proportions of the image of the item on the map

How can I do that?

Solution

finally i remove the ontap area by clearing the ontap method
