I've written something like this before - you want a few icons arranged in a circle, and each icon is clickable?
I created a custom layout, extending the ViewGroup, overriding onMeasure and onLayout. In the Activity I made a listener that implements View.OnTouchListener. It checks if the area which you've touched is within the 'donut' which the icons circle around. I assume you want to click on the icon, if you touch the icon and have not moved more than 10 pixels (Pythagoras distance) when you detect MotionEvent.ACTION_UP. However I have not resumed work on this and it is closed source since it was developed for my employer. I'm not sure how you'd continue animating it when you fling it.
