TextView value changes back to previous value after scroll in base adapter

When I click on the holder.feedUpVoteButton , the text changes +=1 correctly. However, when I scroll down and scroll back up, the text value is reverted to the value it had before it was clicked. I refuse to use notifyDatasetChanged because I am not adding anything or removing anything from the list. public class CustomFeedListViewAdapter extends BaseAdapter{ CustomFeedListViewAdapter customFeedListViewAdapter; Date createdAt, currentDate; int num; static HashMap
