Answer 2

Check out this small project here: https://github.com/serzhby/MultiselectGridViewSample. It's far from perfect, but I think the idea of implementation should be clear. You should change the code for your particular need.

The main idea is to use GridView class as a base class. By overriding the onTouchEvent method we can detect which element was selected. Further processing is pretty staightforward.

Feel free to ask if you have any questions.
