问题
I am making a slot machine app and using kankan's wheel for the same. I want to modify the library such that when the rotation stops the item it will point shoud be the one that I set . I have done this but there is a glitch that shows that we have changed the actual image to the one that we want . How to achieve this?
Update:
I have researched a lot on this and if I am right , android scroll is based on duration and distance not items . From kankan's wheel library I can get current item .Now , I am trying to stop the animation as well as scroll , as soon as a certain duration has been reached and the item is the one that I want (through index) . But this is not working .Please help!!

This is the code. Through this code, when slot stops I want it to scroll some more untill it reaches the image position that I receaved from server. I can do this .But this is providing a lil glitch . Is there any way to stop scrolling when the image is reached as soon as certain duration is reached.
P.S. If you need anymore detail I can provide you. P.P.S. Screenshots wont give you any detailed insight about the issue.
回答1:
After days of searching I finally did it.All I had to do was set interpolater as LinearInterpolater and While setting setCurrentItem set animation as true.
