ConcatAdapter.Config.StableIdMode

Kotlin |Java

public static final enum ConcatAdapter.Config.StableIdMode
extends Enum<ConcatAdapter.Config.StableIdMode>

java.lang.Object
↳	java.lang.Enum<androidx.recyclerview.widget.ConcatAdapter.Config.StableIdMode>
	↳	androidx.recyclerview.widget.ConcatAdapter.Config.StableIdMode

Defines how ConcatAdapter handle stable ids (RecyclerView.Adapter.hasStableIds()).

Summary

Enum values
`ConcatAdapter.Config.StableIdMode`	`ISOLATED_STABLE_IDS` In this mode, `ConcatAdapter` will return `true` from `RecyclerView.Adapter.hasStableIds()` and will require all added `RecyclerView.Adapter`s to have stable ids.
`ConcatAdapter.Config.StableIdMode`	`NO_STABLE_IDS` In this mode, `ConcatAdapter` ignores the stable ids reported by sub adapters.
`ConcatAdapter.Config.StableIdMode`	`SHARED_STABLE_IDS` In this mode, `ConcatAdapter` will return `true` from `RecyclerView.Adapter.hasStableIds()` and will require all added `RecyclerView.Adapter`s to have stable ids.

Enum values

ISOLATED_STABLE_IDS

public static final ConcatAdapter.Config.StableIdMode ISOLATED_STABLE_IDS

In this mode, ConcatAdapter will return true from RecyclerView.Adapter.hasStableIds() and will require all added RecyclerView.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 RecyclerView.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 RecyclerView.ViewHolder.getItemId() might differ from the value returned from RecyclerView.Adapter.getItemId(int). Adding an adapter without stable ids will result in an IllegalArgumentException.

NO_STABLE_IDS

public static final ConcatAdapter.Config.StableIdMode NO_STABLE_IDS

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

SHARED_STABLE_IDS

public static final ConcatAdapter.Config.StableIdMode SHARED_STABLE_IDS

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