A material style progress wheel compatible with 2.3
I needed to keep a consistent (or as close as possible) look in an app across all Android Versions. The progress wheel is quite cool in Lollipop, and pretty horrible on Gingerbread.
So I created this. This view uses Progress Wheel as a base, but has been almost completely rewritten (the original view uses handlers for updating the wheel).
This implementation tries to follow as close as possible the guidelines for the circular progress as described here.
This is how it looks in indeterminate mode (the spinSpeed here is 0.64 which is the default, look below how to change it):
And in determinate mode (here the spinSpeed is set to 0.333):
You can also have a linear determinate progress mode if you don't like the animation.
