Does not save the current state while scrolling instead stores previous state of image for specific type of scroll

Hi,
I was providing buttons to scroll image left or right. On click I set the speed and started the scrolling in selected direction for certain amount of time(used thread for this). Then when i scroll the image to other direction then it starts scrolling from image's start, actually it should scroll to other direction from the current position shown on UI.
