I don't know it's the best way or not but this is the way I know.

First, create your picture as you wish and save it.
Start to design your screen. Create a scrollview on main layout. Scrollview's and the picture's dimension should be equal.
Draw picture bitmap to scrollview's panel.
Use array to save fixed points. In scrollview Touch action, check click point in order to equal one of the fixed points. To check scrollview touch position use scrollview Offset points.
