Currently you have 1 variable per activity to store the quantity. If you want to store it per item, you should add: int qty; to be a member in FeedItem class.

Remove:

convertView.setTag(Integer.valueOf(id));

and similar to plus, you'll need to add:

minus.setTag(item.getId());

Then instead of qty++; or basically in every place in the onClick instead of qty you'll need to use item.qty:

Integer id = view.getTag();
FeedItem item = filteredfeedItems.get(id);
item.qty++;
location.setText(String.valueOf(item.qty));

Update:

I think you're mixing FeedItem.id with position. If you're not changing the order / amount of items in the list then you could ALWAYS use position. Instead of:

minus.setTag(item.getId());

try:

minus.setTag(position);

and the same for plus
