    SwipeDismissList.OnDismissCallback callback = new SwipeDismissList.OnDismissCallback() {
        // Gets called whenever the user deletes an item.
        public SwipeDismissList.Undoable onDismiss(AbsListView listView, final int position) {
            // Get your item from the adapter (mAdapter being an adapter for MyItem objects)
            final MyItem deletedItem = lviewAdapter.getItem(position);
            // Delete item from adapter
            lviewAdapter.remove(deletedItem);
            // Return an Undoable implementing every method
            return new SwipeDismissList.Undoable() {

                // Method is called when user undoes this deletion

You have the line: final MyItem deletedItem = lviewAdapter.getItem(position); I don't see an import to a MyItem class in the top of the file. If you store MyItem obejcts in the adapter you will need to import it. That is also what the error means. If a type cannot be found, you have forgotten to import it correctly (or it doesn't exist at all).

Please provide an example for this. How and where should I write it in my adapter?

This is a very, very basic java coding question not anyhow related to this library. Sorry, but I don't want to describe that in any more detail then I did above. If that wasn't understandable, I highly recommend reading some Java coding guides to get more known to the language.
