8 years ago @ashishoc Please post the adapter code you are using, if possible. Generally, adding an entry to the adapters data should always be accompanied by a call to notifyItemInserted(int position), but I'm not sure whether that solves your case.

8 years ago alternatively is there way to restore normal state while swiping left? Some time need to restore item rather then deletion.

8 years ago @ashishoc Try adding the following after inserting the item, so the code looks like this:
adapter.mDataset.add(getItem());
adapter.notifyItemInserted(adapter.mDataset.size() - 1);Currently there is no way of programmatically undoing a swipe, and I probably won't add this in the near future due to limited time. Pull Requests are welcome though 😃!

8 years ago Thanks, Btw I came to this solution for now..
if (direction == SWIPE_LEFT) {
//restore state
notifyItemChanged(position);
}
I'm trying to add new Item in list using adapter instance after setting adapter.
