ListView Animation not working on first/top 3-4 visible list items

Question

someone already asked a similar question here But my animation works fine for all other list items except top 3-4 list items that are visible after the listview is created. Basically, i call NotifyDataSetChanged() and then based on a condition implemented in getView() i start valueAnimation on TextView. I have no idea why its listview behaving like this.. and What could be the reason behind this?
And how can i handle this issue without calling InvalidaeViews().
I have double/triple checked my logic and even asked someone else so lets assume my logic is working fine. Thanks.

I had a similar problem, and instead of

NotifyDataSetChanged()

Which didn't change anything, I tried with creating a new adapter, and set it to the listview.

userAdapter = new UserCustomAdapter(.....);
userList.setAdapter(userAdapter);

Hope it helps.

EDIT : check these lines too

  if (row == null) {
       LayoutInflater inflater = ((Activity) context).getLayoutInflater();
       row = inflater.inflate(layoutResourceId, parent, false);
       holder = new UserHolder();
      } else {
       holder = (UserHolder) row.getTag();
      }

Thanks. it totally works but is there a way that i could do it using `notifyDataSetChanged()`? And why list view is behaving like this? – Taimur Amjad Dec 30 '14 at 08:59
You should check the else case of your "if (row == null)" in your adapter's get View. Accept plz answer if OK ;-) – Stéphane GROSSMANN Dec 30 '14 at 09:32
^well it definitely work (so does `invalidateView()`) but this isn't what i am looking for. i need to do it without recreating the list. – Taimur Amjad Dec 30 '14 at 10:21
U didn't have to recreate the list, just to update the adpter with the two lines. I although updated the answer. – Stéphane GROSSMANN Dec 30 '14 at 10:43

Finally i have solved it using [RecyclerView][1].
Now i don't have to invalidateViews() or reset the new MyAdapter(...).
Also another issue i was facing was when i run animation on a textview (in a list item) and on scrolling (listview) your viewHolder recycle/reuses that list item then the animation might be running on textview. So i have to handle this as well. Thanks
