Hi Nick , Thanks a lot for your reply. I did the same you suggested but it had revealed few issues:
after implementing all three steps and when i did below step also *- After the animations have finished insert a new Row into the List at the insertion point, change the child view height back to a single row height and destroy the dummy row view.* * * *-*when i inserted Row into the insertion point and called notifyDatasetChanged for the list to update the row it showed some jerk because list's getview method called and repopulate the list again and i needed not to change the child view height back as getView changed its height back to original.Animation was not that smooth as its in the youtube video. If i misunderstood your stpes ,and if possible ,could u please create a demo project and send it to me to [email protected] ll be grateful to you.
