StableIdMode

In this mode, ConcatAdapter ignores the stable ids reported by sub adapters. This is the default mode. Adding an Adapter with stable ids will result in a warning as it will be ignored.

In this mode, ConcatAdapter will return true from hasStableIds and will require all added Adapters to have stable ids. As two different adapters may return same stable ids because they are unaware of each-other, ConcatAdapter will isolate each Adapter's id pool from each other such that it will overwrite the reported stable id before reporting back to the RecyclerView. In this mode, the value returned from getItemId might differ from the value returned from getItemId. Adding an adapter without stable ids will result in an IllegalArgumentException.

In this mode, ConcatAdapter will return true from hasStableIds and will require all added Adapters to have stable ids. Unlike ISOLATED_STABLE_IDS, ConcatAdapter will not override the returned item ids. In this mode, child Adapters must be aware of each-other and never return the same id unless and item is moved between Adapters. Adding an adapter without stable ids will result in an IllegalArgumentException.

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Returns an array containing the constants of this enum type, in the order they're declared. This method may be used to iterate over the constants.
