问题
I am trying to create a circular seekbar with discrete non-linear values. I also want these values to appear outside the circle:
I looked at a number of versions from GitHub with the most promising being the one by JesusM However, I can't think of an easy way to put the values on the outside of the circle. Can anyone think of an easy way to put the "marks" outside the circle.
The one example I did find is the time-selector for the alarm in Marshmallow. Where can I find the source for that?
