DataChangeObserver in SelectableAdapter

[lexius]

DataChangeObserver in SelectableAdapter must implement

public void onItemRangeChanged(int positionStart, int itemCount) public void onItemRangeChanged(int positionStart, int itemCount, Object payload) public void onItemRangeInserted(int positionStart, int itemCount) public void onItemRangeRemoved(int positionStart, int itemCount) public void onItemRangeMoved(int fromPosition, int toPosition, int itemCount)

These methods are already implemented, and left blank in the base class.

Sorry, I didn't understand the significance of the bug until now. At the moment I've implemented onItemRangeInserted, onItemRangeRemoved and onItemRangeMoved. I have not implemented the two variants of onItemRangeChanged because I don't see the point in doing it: a data change in a range of items should not affect the selection status of those items, nor modify the selected ArrayList size. I, at least, fail to see any potential use case.
