Deprecated.

Called by the DiffUtil when it wants to check whether two items have the same data. DiffUtil uses this information to detect if the contents of an item has changed.

DiffUtil uses this method to check equality instead of Object.equals(Object) so that you can change its behavior depending on your UI.

This method is called only if #areItemsTheSame(T, T) returns true for these items.

Parameters:

oldItem - The old item.

newItem - The new item which replaces the old item.

Returns:

True if the contents of the items are the same or false if they are different.
