Super Special Checkboxes-Android

I have problem with checkboxes. I know how to use listviews with checkboxes. But I need something special. I need solution, or more precisely advice. I have 4 checkboxes. When I check checkbox 1 + checkbox 2 and click DONE I want to start another activity(activity 1). Then when I check checkbox 1 + checkbox 3 and click DONE I want to start another activity(activity 2) and so on. Any advice? Maybe it´s easy but I´m still beginner. Sorry. Thank you.
