used for my own concern..change according to your wish
its a simple object Animator type... use your own image for the animation... to place a degree calculation in Mainactivity.java it is tough to understand,,, i will try to explain
in this image...has 10 sectors. total spin wheel degree= 360. for each sector it is=360/10 => 36 degree. for example, its not a actual content consider first,sector as position (5) in my wheel image its starts from half the sector as 36 degree that means 36/2=18 degree. so i keep my factor as 18 degree and i increasing by the real numbers upto 10 for my sectors to complete. only 0 degree is little different, it starts from 360 degree (-) factor and ends with 0 degree (+) factor.
kindly, make sure about setting the degree correctly....
