Method Detail

onActionCanceled

void onActionCanceled(int action,
                      java.util.List<java.lang.Integer> positions)

Called when Undo event is triggered. Perform custom action after restoration.

Usually for a delete restoration you should call FlexibleAdapter#restoreDeletedItems().

Parameters:

action - one of UndoHelper.Action.REMOVE, UndoHelper.Action.UPDATE

positions - positions affected

onActionConfirmed

void onActionConfirmed(int action,
                       int event)

Called when Undo timeout is over and action must be committed in the user Database.

Due to Java Generic, it's too complicated and not well manageable if we pass the List<T> object.
So, to get deleted items, use FlexibleAdapter#getDeletedItems() from the implementation of this method.

Parameters:

action - one of UndoHelper.Action.REMOVE, UndoHelper.Action.UPDATE

event - one of Snackbar.Callback#DISMISS_EVENT_SWIPE, Snackbar.Callback#DISMISS_EVENT_MANUAL, Snackbar.Callback#DISMISS_EVENT_TIMEOUT, Snackbar.Callback#DISMISS_EVENT_CONSECUTIVE
