Universal Image Loader has this feature that makes sure to avoid lag during scrolling, but the problem is PauseOnScrollListener can't be casted to MultiColumnListView or the .PLA_AbsListView.setOnScrollListener. Is there many way to have a work around on this?

Well, you have the code here. So just use PLA_AbsListView.setOnScrollListener and do pausing/resuming yourself.
