Drag & Drop OnTouch irregular shaped images

Question

I am working on a simple app, which will allow moving one ImageView & dropping it on another ImageView. I am having problems with how onTouch works. It seems that it always takes rectangular input.

Let's say I have a shape like that: Link

All small dots represent places which will trigger onTouch. But only green ones should... So in other words, I do not want Drag to be triggered when I am touching transparent part of the image.

Is this possible?
