Detecting touch area on Android

Question

Is it possible to detect every pixel being touched? More specifically, when the user touches the screen, is it possible to track all the x-y coordinates of the cluster of po

Answer 1

If you have a listener on your image it will respond that there was a touch within that bounding box, basically.

So, to get what you want, you could, but, I would never do this, create a box around every pixel, or small group of pixels, and listen for a touch.

Wherever you get a touch, it may fire off an event, then you can react accordingly.

I can't think of any other solution that will give you each pixel that a person touched, at one time.

You may want to read up on multitouch though, as there are some suggestions in here that my help you:
