Creating a "dots" inspired game, need help with a touch concept.

I am trying to develop a game that uses touch between multiple objects. I need to detect when multiple items are touched on one swipe of the finger. The game is similar to "Dots" if you have ever played it. So I need to detect when a dot is pressed and then from there when the finger is dragged to detect the next dot that is touched. I need to keep this going until the finger is lifted. Using dispatchtouchevent and viewgroups is on the right track I think, but that is the furthest I have gotten.
