expandablerecyclerview's Issues

Updating a list item

Thank you very much for the example of RecyclerViev implementation. I want to ask how can I implement updating the list without redrawing all or one of the elements, for example, if I want to change only the price of an item. Is there a way to implement DiffUtil or something else?
