Android: stop scrolling gallery without selecting an item

I am currently working with gallery browsing, and during onFling it scrolls pretty fast. My problem is that I configured onClick of each item to jump to a new action. But I would like it to work if the gallery is not currently scrolling. If the gallery scrolls, I want the first click to just stop scrolling at the current position.

Can someone use a code that allows me to check the scroll status of the gallery or my own gallery code that will stop the scroll action?

Thanks Josh
