# RecyclerView
| This package is part of the Android[support library](https://developer.android.com/topic/libraries/support-library)which is no longer maintained. The support library has been superseded by[AndroidX](https://developer.android.com/jetpack/androidx)which is part of[Jetpack](https://developer.android.com/jetpack). We recommend using the AndroidX libraries in all new projects. You should also consider[migrating](https://developer.android.com/jetpack/androidx/migrate)existing projects to AndroidX. To find the AndroidX class that maps to this deprecated class, see the AndroidX support library[class mappings](https://developer.android.com/jetpack/androidx/migrate/class-mappings).

*** ** * ** ***
A flexible view for providing a limited window into a large data set.
### Glossary of terms:
- *Adapter:* A subclass of[RecyclerView.Adapter](https://developer.android.com/reference/android/support/v7/widget/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[getChildAt(int)](https://developer.android.com/reference/android/view/ViewGroup.html#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](https://developer.android.com/reference/android/support/v7/widget/RecyclerView.Adapter)and[RecyclerView.LayoutManager](https://developer.android.com/reference/android/support/v7/widget/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.[getLayoutPosition()](https://developer.android.com/reference/android/support/v7/widget/RecyclerView.ViewHolder#getLayoutPosition()),[findViewHolderForLayoutPosition(int)](https://developer.android.com/reference/android/support/v7/widget/RecyclerView#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.[getAdapterPosition()](https://developer.android.com/reference/android/support/v7/widget/RecyclerView.ViewHolder#getAdapterPosition()),[findViewHolderForAdapterPosition(int)](https://developer.android.com/reference/android/support/v7/widget/RecyclerView#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[getAdapterPosition()](https://developer.android.com/reference/android/support/v7/widget/RecyclerView.ViewHolder#getAdapterPosition()). Beware that these methods may not be able to calculate adapter positions if[notifyDataSetChanged()](https://developer.android.com/reference/android/support/v7/widget/RecyclerView.Adapter#notifyDataSetChanged())has been called and new layout has not yet been calculated. For this reasons, you should carefully handle[NO_POSITION](https://developer.android.com/reference/android/support/v7/widget/RecyclerView#NO_POSITION)or`null`results from these methods.
When writing a[RecyclerView.LayoutManager](https://developer.android.com/reference/android/support/v7/widget/RecyclerView.LayoutManager)you almost always want to use layout positions whereas when writing an[RecyclerView.Adapter](https://developer.android.com/reference/android/support/v7/widget/RecyclerView.Adapter), you probably want to use adapter positions.

void addItemDecoration (RecyclerView.ItemDecoration decor)
```
Add an[RecyclerView.ItemDecoration](https://developer.android.com/reference/android/support/v7/widget/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
|
### addItemDecoration

```
void addOnChildAttachStateChangeListener (RecyclerView.OnChildAttachStateChangeListener listener)
```
Register a listener that will be notified whenever a child view is attached to or detached from RecyclerView.
This listener will be called when a LayoutManager or the RecyclerView decides that a child view is no longer needed. If an application associates expensive or heavyweight data with item views, this may be a good place to release or free those resources.
| Parameters ||
|------------|------------------------------------------------------------------------------|
| `listener` | `RecyclerView.OnChildAttachStateChangeListener`: Listener to register
|
### addOnItemTouchListener
added in[version 22.1.0](https://developer.android.com/topic/libraries/support-library/revisions)
```
void addOnItemTouchListener (RecyclerView.OnItemTouchListener listener)
```
Add an[RecyclerView.OnItemTouchListener](https://developer.android.com/reference/android/support/v7/widget/RecyclerView.OnItemTouchListener)to intercept touch events before they are dispatched to child views or this view's standard scrolling behavior.
Client code may use listeners to implement item manipulation behavior. Once a listener returns true from[onInterceptTouchEvent(RecyclerView, MotionEvent)](https://developer.android.com/reference/android/support/v7/widget/RecyclerView.OnItemTouchListener#onInterceptTouchEvent(android.support.v7.widget.RecyclerView, android.view.MotionEvent))its[onTouchEvent(RecyclerView, MotionEvent)](https://developer.android.com/reference/android/support/v7/widget/RecyclerView.OnItemTouchListener#onTouchEvent(android.support.v7.widget.RecyclerView, android.view.MotionEvent))method will be called for each incoming MotionEvent until the end of the gesture.
| Parameters ||
|------------|------------------------------------------------------------|
| `listener` | `RecyclerView.OnItemTouchListener`: Listener to add
|

### addOnScrollListener
added in[version 22.1.0](https://developer.android.com/topic/libraries/support-library/revisions)
```
void addOnScrollListener (RecyclerView.OnScrollListener listener)
```

### findViewHolderForAdapterPosition
added in[version 22.1.0](https://developer.android.com/topic/libraries/support-library/revisions)
```
RecyclerView.ViewHolder findViewHolderForAdapterPosition (int position)
```
Return the ViewHolder for the item in the given position of the data set. Unlike[findViewHolderForLayoutPosition(int)](https://developer.android.com/reference/android/support/v7/widget/RecyclerView#findViewHolderForLayoutPosition(int))this method takes into account any pending adapter changes that may not be reflected to the layout yet. On the other hand, if[notifyDataSetChanged()](https://developer.android.com/reference/android/support/v7/widget/RecyclerView.Adapter#notifyDataSetChanged())has been called but the new layout has not been calculated yet, this method will return`null`since the new positions of views are unknown until the layout is calculated.
This method checks only the children of RecyclerView. If the item at the given`position`is not laid out, it*will not*create a new one.
When the ItemAnimator is running a change animation, there might be 2 ViewHolders representing the same Item. In this case, the updated ViewHolder will be returned.
| Parameters ||
|------------|-----------------------------------------------------------------------|
| `position` | `int`: The position of the item in the data set of the adapter
|
| Returns ||
|----------------------------------------------------------------------------------------------------------------------|--------------------------------------------------------------------|

|
### findViewHolderForItemId
added in[version 22.1.0](https://developer.android.com/topic/libraries/support-library/revisions)
```
RecyclerView.ViewHolder findViewHolderForItemId (long id)
```
Return the ViewHolder for the item with the given id. The RecyclerView must use an Adapter with[stableIds](https://developer.android.com/reference/android/support/v7/widget/RecyclerView.Adapter#setHasStableIds(boolean))to return a non-null value.
This method checks only the children of RecyclerView. If the item with the given`id`is not laid out, it*will not*create a new one. When the ItemAnimator is running a change animation, there might be 2 ViewHolders with the same id. In this case, the updated ViewHolder will be returned.
| Parameters ||
|------|----------------------------------------------|
| `id` | `long`: The id for the requested item
|
| Returns ||
|----------------------------------------------------------------------------------------------------------------------|--------------------------------------------------------------------------|
| [RecyclerView.ViewHolder](https://developer.android.com/reference/android/support/v7/widget/RecyclerView.ViewHolder) | The ViewHolder with the given`id`or null if there is no such item
|
### findViewHolderForLayoutPosition
added in[version 22.1.0](https://developer.android.com/topic/libraries/support-library/revisions)
```
RecyclerView.ViewHolder findViewHolderForLayoutPosition (int position)
```
Return the ViewHolder for the item in the given position of the data set as of the latest layout pass.
This method checks only the children of RecyclerView. If the item at the given`position`is not laid out, it*will not*create a new one.
Note that when Adapter contents change, ViewHolder positions are not updated until the next layout calculation. If there are pending adapter updates, the return value of this method may not match your adapter contents. You can use #[getAdapterPosition()](https://developer.android.com/reference/android/support/v7/widget/RecyclerView.ViewHolder#getAdapterPosition())to get the current adapter position of a ViewHolder.
When the ItemAnimator is running a change animation, there might be 2 ViewHolders with the same layout position representing the same Item. In this case, the updated ViewHolder will be returned.
| Parameters ||
|------------|-----------------------------------------------------------------------|
| `position` | `int`: The position of the item in the data set of the adapter
|
| Returns ||
|----------------------------------------------------------------------------------------------------------------------|--------------------------------------------------------------------|

### focusSearch
```
View focusSearch (View focused,
int direction)
```
Since RecyclerView is a collection ViewGroup that includes virtual children (items that are in the Adapter but not visible in the UI), it employs a more involved focus search strategy that differs from other ViewGroups.
It first does a focus search within the RecyclerView. If this search finds a View that is in the focus direction with respect to the currently focused View, RecyclerView returns that child as the next focus target. When it cannot find such child, it calls[onFocusSearchFailed(View, int, Recycler, State)](https://developer.android.com/reference/android/support/v7/widget/RecyclerView.LayoutManager#onFocusSearchFailed(android.view.View, int, android.support.v7.widget.RecyclerView.Recycler, android.support.v7.widget.RecyclerView.State))to layout more Views in the focus search direction. If LayoutManager adds a View that matches the focus search criteria, it will be returned as the focus search result. Otherwise, RecyclerView will call parent to handle the focus search like a regular ViewGroup.
When the direction is[FOCUS_FORWARD](https://developer.android.com/reference/android/view/View.html#FOCUS_FORWARD)or[FOCUS_BACKWARD](https://developer.android.com/reference/android/view/View.html#FOCUS_BACKWARD), a View that is not in the focus direction is still valid focus target which may not be the desired behavior if the Adapter has more children in the focus direction. To handle this case, RecyclerView converts the focus direction to an absolute direction and makes a preliminary focus search in that direction. If there are no Views to gain focus, it will call[onFocusSearchFailed(View, int, Recycler, State)](https://developer.android.com/reference/android/support/v7/widget/RecyclerView.LayoutManager#onFocusSearchFailed(android.view.View, int, android.support.v7.widget.RecyclerView.Recycler, android.support.v7.widget.RecyclerView.State))before running a focus search with the original (relative) direction. This allows RecyclerView to provide better candidates to the focus search while still allowing the view system to take focus from the RecyclerView and give it to a more suitable child if such child exists.
| Parameters ||
|-------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| `focused` | `View`: The view that currently has focus
|
| `direction` | `int`: One of[FOCUS_UP](https://developer.android.com/reference/android/view/View.html#FOCUS_UP),[FOCUS_DOWN](https://developer.android.com/reference/android/view/View.html#FOCUS_DOWN),[FOCUS_LEFT](https://developer.android.com/reference/android/view/View.html#FOCUS_LEFT),[FOCUS_RIGHT](https://developer.android.com/reference/android/view/View.html#FOCUS_RIGHT),[FOCUS_FORWARD](https://developer.android.com/reference/android/view/View.html#FOCUS_FORWARD),[FOCUS_BACKWARD](https://developer.android.com/reference/android/view/View.html#FOCUS_BACKWARD)or 0 for not applicable.

### isComputingLayout
added in[version 24.1.0](https://developer.android.com/topic/libraries/support-library/revisions)
```
boolean isComputingLayout ()
```
Returns whether RecyclerView is currently computing a layout.
If this method returns true, it means that RecyclerView is in a lockdown state and any attempt to update adapter contents will result in an exception because adapter contents cannot be changed while RecyclerView is trying to compute the layout.
It is very unlikely that your code will be running during this state as it is called by the framework when a layout traversal happens or RecyclerView starts to scroll in response to system events (touch, accessibility etc).
This case may happen if you have some custom logic to change adapter contents in response to a View callback (e.g. focus change callback) which might be triggered during a layout calculation. In these cases, you should just postpone the change using a Handler or a similar mechanism.
| Returns ||
|-----------|-------------------------------------------------------------------------------|

```
void onChildAttachedToWindow (View child)
```

Subclasses of RecyclerView may want to perform extra bookkeeping or modifications of child views as they become attached. This will be called before a[RecyclerView.LayoutManager](https://developer.android.com/reference/android/support/v7/widget/RecyclerView.LayoutManager)measures or lays out the view and is a good time to perform these changes.
| Parameters ||
|---------|-----------------------------------------------------------------------------------------------|
| `child` | `View`: Child view that is now attached to this RecyclerView and its associated window
|
### onChildDetachedFromWindow
added in[version 22.1.0](https://developer.android.com/topic/libraries/support-library/revisions)
```
void onChildDetachedFromWindow (View child)
```
Called when an item view is detached from this RecyclerView.
Subclasses of RecyclerView may want to perform extra bookkeeping or modifications of child views as they become detached. This will be called as a[RecyclerView.LayoutManager](https://developer.android.com/reference/android/support/v7/widget/RecyclerView.LayoutManager)fully detaches the child view from the parent and its window.
| Parameters ||
|---------|-------------------------------------------------------------------------------------------------|
| `child` | `View`: Child view that is now detached from this RecyclerView and its associated window

|
### onScrollStateChanged
added in[version 22.1.0](https://developer.android.com/topic/libraries/support-library/revisions)
```
void onScrollStateChanged (int state)
```
Called when the scroll state of this RecyclerView changes. Subclasses should use this method to respond to state changes instead of an explicit listener.
This method will always be invoked before listeners, but after the LayoutManager responds to the scroll state change.
| Parameters ||
|---------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| `state` | `int`: the new scroll state, one of[SCROLL_STATE_IDLE](https://developer.android.com/reference/android/support/v7/widget/RecyclerView#SCROLL_STATE_IDLE),[SCROLL_STATE_DRAGGING](https://developer.android.com/reference/android/support/v7/widget/RecyclerView#SCROLL_STATE_DRAGGING)or[SCROLL_STATE_SETTLING](https://developer.android.com/reference/android/support/v7/widget/RecyclerView#SCROLL_STATE_SETTLING)
|
### onScrolled
added in[version 22.1.0](https://developer.android.com/topic/libraries/support-library/revisions)
```
void onScrolled (int dx,
int dy)
```
Called when the scroll position of this RecyclerView changes. Subclasses should use this method to respond to scrolling within the adapter's data set instead of an explicit listener.
This method will always be invoked before listeners. If a subclass needs to perform any additional upkeep or bookkeeping after scrolling but before listeners run, this is a good place to do so.
This differs from[onScrollChanged(int, int, int, int)](https://developer.android.com/reference/android/view/View.html#onScrollChanged(int, int, int, int))in that it receives the distance scrolled in either direction within the adapter's data set instead of absolute scroll coordinates. Since RecyclerView cannot compute the absolute scroll position from any arbitrary point in the data set,`onScrollChanged`will always receive the current[getScrollX()](https://developer.android.com/reference/android/view/View.html#getScrollX())and[getScrollY()](https://developer.android.com/reference/android/view/View.html#getScrollY())values which do not correspond to the data set scroll position. However, some subclasses may choose to use these fields as special offsets.
| Parameters ||
|------|------------------------------------------------------|
| `dx` | `int`: horizontal distance scrolled in pixels
|
| `dy` | `int`: vertical distance scrolled in pixels
|
### onTouchEvent
```
boolean onTouchEvent (MotionEvent e)

| Parameters ||
|-----|----------------------|
| `e` | `MotionEvent`
|
| Returns ||
|-----------|--------|
| `boolean` |
|

added in[version 27.1.0](https://developer.android.com/topic/libraries/support-library/revisions)
```
void setEdgeEffectFactory (RecyclerView.EdgeEffectFactory edgeEffectFactory)
```
Set a[RecyclerView.EdgeEffectFactory](https://developer.android.com/reference/android/support/v7/widget/RecyclerView.EdgeEffectFactory)for this[RecyclerView](https://developer.android.com/reference/android/support/v7/widget/RecyclerView).
When a new[RecyclerView.EdgeEffectFactory](https://developer.android.com/reference/android/support/v7/widget/RecyclerView.EdgeEffectFactory)is set, any existing over-scroll effects are cleared and new effects are created as needed using[createEdgeEffect(RecyclerView, int)](https://developer.android.com/reference/android/support/v7/widget/RecyclerView.EdgeEffectFactory#createEdgeEffect(android.support.v7.widget.RecyclerView, int))
| Parameters ||
|---------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| `edgeEffectFactory` | `RecyclerView.EdgeEffectFactory`: The[RecyclerView.EdgeEffectFactory](https://developer.android.com/reference/android/support/v7/widget/RecyclerView.EdgeEffectFactory)instance.
|
### setHasFixedSize
added in[version 22.1.0](https://developer.android.com/topic/libraries/support-library/revisions)
```
void setHasFixedSize (boolean hasFixedSize)
```
RecyclerView can perform several optimizations if it can know in advance that RecyclerView's size is not affected by the adapter contents. RecyclerView can still change its size based on other factors (e.g. its parent's size) but this size calculation cannot depend on the size of its children or contents of its adapter (except the number of items in the adapter).
If your use of RecyclerView falls into this category, set this to`true`. It will allow RecyclerView to avoid invalidating the whole layout when its adapter contents change.
| Parameters ||
|----------------|---------------------------------------------------------------------------------------|
| `hasFixedSize` | `boolean`: true if adapter changes cannot affect the size of the RecyclerView.
|
### setItemAnimator
added in[version 22.1.0](https://developer.android.com/topic/libraries/support-library/revisions)
```
void setItemAnimator (RecyclerView.ItemAnimator animator)
```
Sets the[RecyclerView.ItemAnimator](https://developer.android.com/reference/android/support/v7/widget/RecyclerView.ItemAnimator)that will handle animations involving changes to the items in this RecyclerView. By default, RecyclerView instantiates and uses an instance of[DefaultItemAnimator](https://developer.android.com/reference/android/support/v7/widget/DefaultItemAnimator). Whether item animations are enabled for the RecyclerView depends on the ItemAnimator and whether the LayoutManager[supports item animations](https://developer.android.com/reference/android/support/v7/widget/RecyclerView.LayoutManager#supportsPredictiveItemAnimations()).
| Parameters ||
|------------|---------------------------------------------------------------------------------------------------------------------------------------------------------|
| `animator` | `RecyclerView.ItemAnimator`: The ItemAnimator being set. If null, no animations will occur when changes occur to the items in this RecyclerView.
|
### setItemViewCacheSize
added in[version 22.1.0](https://developer.android.com/topic/libraries/support-library/revisions)
```
void setItemViewCacheSize (int size)
```
Set the number of offscreen views to retain before adding them to the potentially shared[recycled view pool](https://developer.android.com/reference/android/support/v7/widget/RecyclerView#getRecycledViewPool()).
The offscreen view cache stays aware of changes in the attached adapter, allowing a LayoutManager to reuse those views unmodified without needing to return to the adapter to rebind them.
| Parameters ||
|--------|----------------------------------------------------------------------------------------------------------|
| `size` | `int`: Number of views to cache offscreen before returning them to the general recycled view pool
|
### setLayoutFrozen
added in[version 24.1.0](https://developer.android.com/topic/libraries/support-library/revisions)
```
void setLayoutFrozen (boolean frozen)
```
Enable or disable layout and scroll. After`setLayoutFrozen(true)`is called, Layout requests will be postponed until`setLayoutFrozen(false)`is called; child views are not updated when RecyclerView is frozen,[smoothScrollBy(int, int)](https://developer.android.com/reference/android/support/v7/widget/RecyclerView#smoothScrollBy(int, int)),[scrollBy(int, int)](https://developer.android.com/reference/android/support/v7/widget/RecyclerView#scrollBy(int, int)),[scrollToPosition(int)](https://developer.android.com/reference/android/support/v7/widget/RecyclerView#scrollToPosition(int))and[smoothScrollToPosition(int)](https://developer.android.com/reference/android/support/v7/widget/RecyclerView#smoothScrollToPosition(int))are dropped; TouchEvents and GenericMotionEvents are dropped;[onFocusSearchFailed(View, int, Recycler, State)](https://developer.android.com/reference/android/support/v7/widget/RecyclerView.LayoutManager#onFocusSearchFailed(android.view.View, int, android.support.v7.widget.RecyclerView.Recycler, android.support.v7.widget.RecyclerView.State))will not be called.
`setLayoutFrozen(true)`does not prevent app from directly calling[scrollToPosition(int)](https://developer.android.com/reference/android/support/v7/widget/RecyclerView.LayoutManager#scrollToPosition(int)),[smoothScrollToPosition(RecyclerView, State, int)](https://developer.android.com/reference/android/support/v7/widget/RecyclerView.LayoutManager#smoothScrollToPosition(android.support.v7.widget.RecyclerView, android.support.v7.widget.RecyclerView.State, int)).
[setAdapter(Adapter)](https://developer.android.com/reference/android/support/v7/widget/RecyclerView#setAdapter(android.support.v7.widget.RecyclerView.Adapter))and[swapAdapter(Adapter, boolean)](https://developer.android.com/reference/android/support/v7/widget/RecyclerView#swapAdapter(android.support.v7.widget.RecyclerView.Adapter, boolean))will automatically stop frozen.
Note: Running ItemAnimator is not stopped automatically, it's caller's responsibility to call ItemAnimator.end().
| Parameters ||
|----------|-------------------------------------------------------------------------|
| `frozen` | `boolean`: true to freeze layout and scroll, false to re-enable.
|
### setLayoutManager
added in[version 22.1.0](https://developer.android.com/topic/libraries/support-library/revisions)
```
void setLayoutManager (RecyclerView.LayoutManager layout)
```
Set the[RecyclerView.LayoutManager](https://developer.android.com/reference/android/support/v7/widget/RecyclerView.LayoutManager)that this RecyclerView will use.
In contrast to other adapter-backed views such as[ListView](https://developer.android.com/reference/android/widget/ListView.html)or[GridView](https://developer.android.com/reference/android/widget/GridView.html), RecyclerView allows client code to provide custom layout arrangements for child views. These arrangements are controlled by the[RecyclerView.LayoutManager](https://developer.android.com/reference/android/support/v7/widget/RecyclerView.LayoutManager). A LayoutManager must be provided for RecyclerView to function.
Several default strategies are provided for common uses such as lists and grids.
| Parameters ||
|----------|-----------------------------------------------------------|
| `layout` | `RecyclerView.LayoutManager`: LayoutManager to use
|
### setNestedScrollingEnabled
```
void setNestedScrollingEnabled (boolean enabled)
```
| Parameters ||
|-----------|------------------|
| `enabled` | `boolean`

### setOnFlingListener
added in[version 25.1.0](https://developer.android.com/topic/libraries/support-library/revisions)
```
void setOnFlingListener (RecyclerView.OnFlingListener onFlingListener)
```
Set a[RecyclerView.OnFlingListener](https://developer.android.com/reference/android/support/v7/widget/RecyclerView.OnFlingListener)for this[RecyclerView](https://developer.android.com/reference/android/support/v7/widget/RecyclerView).
If the[RecyclerView.OnFlingListener](https://developer.android.com/reference/android/support/v7/widget/RecyclerView.OnFlingListener)is set then it will receive calls to[fling(int, int)](https://developer.android.com/reference/android/support/v7/widget/RecyclerView#fling(int, int))and will be able to intercept them.
| Parameters ||
|-------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

### setPreserveFocusAfterLayout
added in[version 24.1.0](https://developer.android.com/topic/libraries/support-library/revisions)
```
void setPreserveFocusAfterLayout (boolean preserveFocusAfterLayout)
```
Set whether the RecyclerView should try to keep the same Item focused after a layout calculation or not.
Usually, LayoutManagers keep focused views visible before and after layout but sometimes, views may lose focus during a layout calculation as their state changes or they are replaced with another view due to type change or animation. In these cases, RecyclerView can request focus on the new view automatically.
| Parameters ||
|----------------------------|---------------------------------------------------------------------------------------------------------------------|
| `preserveFocusAfterLayout` | `boolean`: Whether RecyclerView should preserve focused Item during a layout calculations. Defaults to true.
|
**See also:**
- [getPreserveFocusAfterLayout()](https://developer.android.com/reference/android/support/v7/widget/RecyclerView#getPreserveFocusAfterLayout())
### setRecycledViewPool
added in[version 22.1.0](https://developer.android.com/topic/libraries/support-library/revisions)
```
void setRecycledViewPool (RecyclerView.RecycledViewPool pool)
```
Recycled view pools allow multiple RecyclerViews to share a common pool of scrap views. This can be useful if you have multiple RecyclerViews with adapters that use the same view types, for example if you have several data sets with the same kinds of item views displayed by a[ViewPager](https://developer.android.com/reference/android/support/v4/view/ViewPager).
| Parameters ||
|--------|---------------------------------------------------------------------------------------------------------------------|
| `pool` | `RecyclerView.RecycledViewPool`: Pool to set. If this parameter is null a new pool will be created and used.

### setRecyclerListener
added in[version 22.1.0](https://developer.android.com/topic/libraries/support-library/revisions)
```
void setRecyclerListener (RecyclerView.RecyclerListener listener)
```
Register a listener that will be notified whenever a child view is recycled.
This listener will be called when a LayoutManager or the RecyclerView decides that a child view is no longer needed. If an application associates expensive or heavyweight data with item views, this may be a good place to release or free those resources.
| Parameters ||
|------------|--------------------------------------------------------------------------------|
| `listener` | `RecyclerView.RecyclerListener`: Listener to register, or null to clear
|
### setScrollingTouchSlop
added in[version 22.1.0](https://developer.android.com/topic/libraries/support-library/revisions)

### smoothScrollToPosition
added in[version 22.1.0](https://developer.android.com/topic/libraries/support-library/revisions)
```
void smoothScrollToPosition (int position)
```
Starts a smooth scroll to an adapter position.
To support smooth scrolling, you must override[smoothScrollToPosition(RecyclerView, State, int)](https://developer.android.com/reference/android/support/v7/widget/RecyclerView.LayoutManager#smoothScrollToPosition(android.support.v7.widget.RecyclerView, android.support.v7.widget.RecyclerView.State, int))and create a[RecyclerView.SmoothScroller](https://developer.android.com/reference/android/support/v7/widget/RecyclerView.SmoothScroller).
[RecyclerView.LayoutManager](https://developer.android.com/reference/android/support/v7/widget/RecyclerView.LayoutManager)is responsible for creating the actual scroll action. If you want to provide a custom smooth scroll logic, override[smoothScrollToPosition(RecyclerView, State, int)](https://developer.android.com/reference/android/support/v7/widget/RecyclerView.LayoutManager#smoothScrollToPosition(android.support.v7.widget.RecyclerView, android.support.v7.widget.RecyclerView.State, int))in your LayoutManager.
| Parameters ||
|------------|-------------------------------------------------|
| `position` | `int`: The adapter position to scroll to
|
**See also:**
- [smoothScrollToPosition(RecyclerView, State, int)](https://developer.android.com/reference/android/support/v7/widget/RecyclerView.LayoutManager#smoothScrollToPosition(android.support.v7.widget.RecyclerView, android.support.v7.widget.RecyclerView.State, int))
### startNestedScroll
```
boolean startNestedScroll (int axes)
```
| Parameters ||
|--------|--------------|
| `axes` | `int`
|
| Returns ||
|-----------|--------|
| `boolean` |
|
### startNestedScroll
added in[version 26.1.0](https://developer.android.com/topic/libraries/support-library/revisions)
```
boolean startNestedScroll (int axes,
int type)
```
Begin a nestable scroll operation along the given axes, for the given input type.
A view starting a nested scroll promises to abide by the following contract:
The view will call startNestedScroll upon initiating a scroll operation. In the case of a touch scroll type this corresponds to the initial[ACTION_DOWN](https://developer.android.com/reference/android/view/MotionEvent.html#ACTION_DOWN). In the case of touch scrolling the nested scroll will be terminated automatically in the same manner as[requestDisallowInterceptTouchEvent(boolean)](https://developer.android.com/reference/android/view/ViewParent.html#requestDisallowInterceptTouchEvent(boolean)). In the event of programmatic scrolling the caller must explicitly call[stopNestedScroll(int)](https://developer.android.com/reference/android/support/v4/view/NestedScrollingChild2#stopNestedScroll(int))to indicate the end of the nested scroll.
If`startNestedScroll`returns true, a cooperative parent was found. If it returns false the caller may ignore the rest of this contract until the next scroll. Calling startNestedScroll while a nested scroll is already in progress will return true.
At each incremental step of the scroll the caller should invoke[dispatchNestedPreScroll](https://developer.android.com/reference/android/support/v4/view/NestedScrollingChild2#dispatchNestedPreScroll(int, int, int[], int[], int))once it has calculated the requested scrolling delta. If it returns true the nested scrolling parent at least partially consumed the scroll and the caller should adjust the amount it scrolls by.
After applying the remainder of the scroll delta the caller should invoke[dispatchNestedScroll](https://developer.android.com/reference/android/support/v4/view/NestedScrollingChild2#dispatchNestedScroll(int, int, int, int, int[], int)), passing both the delta consumed and the delta unconsumed. A nested scrolling parent may treat these values differently. See[onNestedScroll(View, int, int, int, int, int)](https://developer.android.com/reference/android/support/v4/view/NestedScrollingParent2#onNestedScroll(android.view.View, int, int, int, int, int)).
| Parameters ||
|--------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| `axes` | `int`: Flags consisting of a combination of[SCROLL_AXIS_HORIZONTAL](https://developer.android.com/reference/android/support/v4/view/ViewCompat#SCROLL_AXIS_HORIZONTAL)and/or[SCROLL_AXIS_VERTICAL](https://developer.android.com/reference/android/support/v4/view/ViewCompat#SCROLL_AXIS_VERTICAL).
|
| `type` | `int`: the type of input which cause this scroll event
|
| Returns ||
|-----------|--------------------------------------------------------------------------------------------------------------|
| `boolean` | true if a cooperative parent was found and nested scrolling has been enabled for the current gesture.
|
### stopNestedScroll
```
void stopNestedScroll ()
```
### stopNestedScroll
added in[version 26.1.0](https://developer.android.com/topic/libraries/support-library/revisions)
```
void stopNestedScroll (int type)
```

Calling this method when a nested scroll is not currently in progress is harmless.
| Parameters ||
|--------|---------------------------------------------------------------|
| `type` | `int`: the type of input which cause this scroll event
|
### stopScroll
added in[version 22.1.0](https://developer.android.com/topic/libraries/support-library/revisions)
```
void stopScroll ()
```
Stop any current scroll in progress, such as one started by[smoothScrollBy(int, int)](https://developer.android.com/reference/android/support/v7/widget/RecyclerView#smoothScrollBy(int, int)),[fling(int, int)](https://developer.android.com/reference/android/support/v7/widget/RecyclerView#fling(int, int))or a touch-initiated fling.
### swapAdapter
added in[version 22.1.0](https://developer.android.com/topic/libraries/support-library/revisions)
```
void swapAdapter (Adapter adapter,
boolean removeAndRecycleExistingViews)
```
Swaps the current adapter with the provided one. It is similar to[setAdapter(Adapter)](https://developer.android.com/reference/android/support/v7/widget/RecyclerView#setAdapter(android.support.v7.widget.RecyclerView.Adapter))but assumes existing adapter and the new adapter uses the same[RecyclerView.ViewHolder](https://developer.android.com/reference/android/support/v7/widget/RecyclerView.ViewHolder)and does not clear the RecycledViewPool.
Note that it still calls onAdapterChanged callbacks.
| Parameters ||
|---------------------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| `adapter` | `Adapter`: The new adapter to set, or null to set no adapter.
|
| `removeAndRecycleExistingViews` | `boolean`: If set to true, RecyclerView will recycle all existing Views. If adapters have stable ids and/or you want to animate the disappearing views, you may prefer to set this to false.
