BaseGridView	An abstract base class for vertically and horizontally scrolling lists.
WearableRecyclerView	Wearable specific implementation of the `RecyclerView` enabling `setCircularScrollingGestureEnabled(boolean)` circular scrolling} and semi-circular layouts.

HorizontalGridView, VerticalGridView

HorizontalGridView	A `ViewGroup` that shows items in a horizontal scrolling list.

A flexible view for providing a limited window into a large data set.

Glossary of terms:

Adapter: A subclass of RecyclerView.Adapter responsible for providing views that represent items in a data set.
Position: The position of a data item within an Adapter.
Index: The index of an attached child view as used in a call to ViewGroup.getChildAt(int). Contrast with Position.
Binding: The process of preparing a child view to display data corresponding to a position within the adapter.
Recycle (view): A view previously used to display data for a specific adapter position may be placed in a cache for later reuse to display the same type of data again later. This can drastically improve performance by skipping initial layout inflation or construction.
Scrap (view): A child view that has entered into a temporarily detached state during layout. Scrap views may be reused without becoming fully detached from the parent RecyclerView, either unmodified if no rebinding is required or modified by the adapter if the view was considered dirty.
Dirty (view): A child view that must be rebound by the adapter before being displayed.

Positions in RecyclerView:

RecyclerView introduces an additional level of abstraction between the RecyclerView.Adapter and RecyclerView.LayoutManager to be able to detect data set changes in batches during a layout calculation. This saves LayoutManager from tracking adapter changes to calculate animations. It also helps with performance because all view bindings happen at the same time and unnecessary bindings are avoided.

For this reason, there are two types of position related methods in RecyclerView:

layout position: Position of an item in the latest layout calculation. This is the position from the LayoutManager's perspective.
adapter position: Position of an item in the adapter. This is the position from the Adapter's perspective.

These two positions are the same except the time between dispatching adapter.notify* events and calculating the updated layout.

Methods that return or receive *LayoutPosition* use position as of the latest layout calculation (e.g. RecyclerView.ViewHolder.getLayoutPosition(), findViewHolderForLayoutPosition(int)). These positions include all changes until the last layout calculation. You can rely on these positions to be consistent with what user is currently seeing on the screen. For example, if you have a list of items on the screen and user asks for the 5^th element, you should use these methods as they'll match what user is seeing.

The other set of position related methods are in the form of *AdapterPosition*. (e.g. RecyclerView.ViewHolder.getAdapterPosition(), findViewHolderForAdapterPosition(int)) You should use these methods when you need to work with up-to-date adapter positions even if they may not have been reflected to layout yet. For example, if you want to access the item in the adapter on a ViewHolder click, you should use RecyclerView.ViewHolder.getAdapterPosition(). Beware that these methods may not be able to calculate adapter positions if RecyclerView.Adapter.notifyDataSetChanged() has been called and new layout has not yet been calculated. For this reasons, you should carefully handle NO_POSITION or null results from these methods.

When writing a RecyclerView.LayoutManager you almost always want to use layout positions whereas when writing an RecyclerView.Adapter, you probably want to use adapter positions.

Presenting Dynamic Data

To display updatable data in a RecyclerView, your adapter needs to signal inserts, moves, and deletions to RecyclerView. You can build this yourself by manually calling adapter.notify* methods when content changes, or you can use one of the easier solutions RecyclerView provides:

List diffing with DiffUtil

If your RecyclerView is displaying a list that is re-fetched from scratch for each update (e.g. from the network, or from a database), DiffUtil can calculate the difference between versions of the list. DiffUtil takes both lists as input and computes the difference, which can be passed to RecyclerView to trigger minimal animations and updates to keep your UI performant, and animations meaningful. This approach requires that each list is represented in memory with immutable content, and relies on receiving updates as new instances of lists. This approach is also ideal if your UI layer doesn't implement sorting, it just presents the data in the order it's given.

The best part of this approach is that it extends to any arbitrary changes - item updates, moves, addition and removal can all be computed and handled the same way. Though you do have to keep two copies of the list in memory while diffing, and must avoid mutating them, it's possible to share unmodified elements between list versions.

There are three primary ways to do this for RecyclerView. We recommend you start with ListAdapter, the higher-level API that builds in List diffing on a background thread, with minimal code. AsyncListDiffer also provides this behavior, but without defining an Adapter to subclass. If you want more control, DiffUtil is the lower-level API you can use to compute the diffs yourself. Each approach allows you to specify how diffs should be computed based on item data.

List mutation with SortedList

If your RecyclerView receives updates incrementally, e.g. item X is inserted, or item Y is removed, you can use SortedList to manage your list. You define how to order items, and it will automatically trigger update signals that RecyclerView can use. SortedList works if you only need to handle insert and remove events, and has the benefit that you only ever need to have a single copy of the list in memory. It can also compute differences with SortedList.replaceAll(Object[]), but this method is more limited than the list diffing behavior above.

Paging Library

The Paging library extends the diff-based approach to additionally support paged loading. It provides the PagedList class that operates as a self-loading list, provided a source of data like a database, or paginated network API. It provides convenient list diffing support out of the box, similar to ListAdapter and AsyncListDiffer. For more information about the Paging library, see the library documentation.

Public constructors

RecyclerView

public RecyclerView (Context context)

Parameters
`context`	`Context`

RecyclerView

public RecyclerView (Context context, 
                AttributeSet attrs)

Parameters
`context`	`Context`
`attrs`	`AttributeSet`

RecyclerView

public RecyclerView (Context context, 
                AttributeSet attrs, 
                int defStyle)

Parameters
`context`	`Context`
`attrs`	`AttributeSet`
`defStyle`	`int`

Public methods

addFocusables

public void addFocusables (ArrayList<View> views, 
                int direction, 
                int focusableMode)

Parameters
`views`	`ArrayList`
`direction`	`int`
`focusableMode`	`int`

public void addItemDecoration (RecyclerView.ItemDecoration decor, 
                int index)

Add an RecyclerView.ItemDecoration to this RecyclerView. Item decorations can affect both measurement and drawing of individual item views.

Item decorations are ordered. Decorations placed earlier in the list will be run/queried/drawn first for their effects on item views. Padding added to views will be nested; a padding added by an earlier decoration will mean further item decorations in the list will be asked to draw/pad within the previous decoration's given area.

Parameters
`decor`	`RecyclerView.ItemDecoration`: Decoration to add
`index`	`int`: Position in the decoration chain to insert this decoration at. If this value is negative the decoration will be added at the end.

public void addItemDecoration (RecyclerView.ItemDecoration decor)

Add an RecyclerView.ItemDecoration to this RecyclerView. Item decorations can affect both measurement and drawing of individual item views.

Parameters
`decor`	`RecyclerView.ItemDecoration`: Decoration to add

public void addOnChildAttachStateChangeListener (RecyclerView.OnChildAttachStateChangeListener listener)
