I am a beginner in android development and would like to create a custom seekbar with two thumbs (not the range bar version).
My goal is to achieve something like this: two thumbs seekbar The red thumb cannot be greater than the yellow.
I found this article which seems to be a good starting point, however I don't understand how to make the thumbs moving around. Only the textviews are changing as I slide my fingers. http://kpbird.blogspot.in/2011/05/android-seek-bar-with-two-thumb.html
