class ViewPager2 : ViewGroup

↳	android.view.View
	↳	android.view.ViewGroup
		↳	androidx.viewpager2.widget.ViewPager2

ViewPager2 replaces androidx.viewpager.widget.ViewPager, addressing most of its predecessor’s pain-points, including right-to-left layout support, vertical orientation, modifiable Fragment collections, etc.

A note on WindowInsets: due to a bug in API 29 and before, WindowInsets were incorrectly dispatched to a View's children and siblings. ViewPager2 offers a fix to make sure that all pages receive the correct insets, but it comes at the cost of not dispatching insets to any siblings of ViewPager2 or siblings of its ancestors that haven't received the insets yet. If you want to handle insets on each page separately (instead of on ViewPager2 or one of its parents), you should install a WindowInsetsApplier by calling WindowInsetsApplier.install(viewPager2). If you don't handle insets on any of the pages, we recommend you don't use the WindowInsetsApplier.

Summary

Nested types
`abstract class ViewPager2.OnPageChangeCallback` Callback interface for responding to changing state of the selected page.
`interface ViewPager2.PageTransformer` A PageTransformer is invoked whenever a visible/attached page is scrolled.

Constants
`const Int`	`OFFSCREEN_PAGE_LIMIT_DEFAULT = -1` Value to indicate that the default caching mechanism of RecyclerView should be used instead of explicitly prefetch and retain pages to either side of the current page.
`const Int`	`ORIENTATION_HORIZONTAL = 0`
`const Int`	`ORIENTATION_VERTICAL = 1`
`const Int`	`SCROLL_STATE_DRAGGING = 1` Indicates that the ViewPager2 is currently being dragged by the user, or programmatically via fake drag functionality.
`const Int`	`SCROLL_STATE_IDLE = 0` Indicates that the ViewPager2 is in an idle, settled state.
`const Int`	`SCROLL_STATE_SETTLING = 2` Indicates that the ViewPager2 is in the process of settling to a final position.

Public functions

fun addItemDecoration(decor: RecyclerView.ItemDecoration): Unit

Add an ItemDecoration to this ViewPager2. 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

Added in 1.0.0

fun addItemDecoration(decor: RecyclerView.ItemDecoration, index: Int): Unit

Add an ItemDecoration to this ViewPager2. Item decorations can affect both measurement and drawing of individual item views.

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.

Throws
`java.lang.IndexOutOfBoundsException`	on indexes larger than `getItemDecorationCount`

beginFakeDrag

Added in 1.0.0

fun beginFakeDrag(): Boolean

Start a fake drag of the pager.

A fake drag can be useful if you want to synchronize the motion of the ViewPager2 with the touch scrolling of another view, while still letting the ViewPager2 control the snapping motion and fling behavior. (e.g. parallax-scrolling tabs.) Call fakeDragBy to simulate the actual drag motion. Call endFakeDrag to complete the fake drag and fling as necessary.

A fake drag can be interrupted by a real drag. From that point on, all calls to fakeDragBy and endFakeDrag will be ignored until the next fake drag is started by calling beginFakeDrag. If you need the ViewPager2 to ignore touch events and other user input during a fake drag, use setUserInputEnabled. If a real or fake drag is already in progress, this method will return false.

Returns
`Boolean`	`true` if the fake drag began successfully, `false` if it could not be started

`fakeDragBy`
`endFakeDrag`
`isFakeDragging`

canScrollHorizontally

fun canScrollHorizontally(direction: Int): Boolean

canScrollVertically

fun canScrollVertically(direction: Int): Boolean

endFakeDrag

Added in 1.0.0

fun endFakeDrag(): Boolean

End a fake drag of the pager.

Returns
`Boolean`	`true` if the fake drag was ended. If `false` is returned, it means there was no fake drag to end.

See also
`beginFakeDrag`
`fakeDragBy`
`isFakeDragging`

fakeDragBy

Added in 1.0.0

fun fakeDragBy(offsetPxFloat: @Px Float): Boolean

Fake drag by an offset in pixels. You must have called beginFakeDrag first. Drag happens in the direction of the orientation. Positive offsets will drag to the previous page, negative values to the next page, with one exception: if layout direction is set to RTL and the ViewPager2's orientation is horizontal, then the behavior will be inverted. This matches the deltas of touch events that would cause the same real drag.

If the pager is not in the fake dragging state anymore, it ignores this call and returns false.

Parameters
`offsetPxFloat: @Px Float`	Offset in pixels to drag by

Returns
`Boolean`	`true` if the fake drag was executed. If `false` is returned, it means there was no fake drag to end.

Added in 1.0.0

fun registerOnPageChangeCallback(callback: ViewPager2.OnPageChangeCallback): Unit

Add a callback that will be invoked whenever the page changes or is incrementally scrolled. See OnPageChangeCallback.

Components that add a callback should take care to remove it when finished.

Parameters
`callback: ViewPager2.OnPageChangeCallback`	callback to add

Added in 1.0.0

fun removeItemDecoration(decor: RecyclerView.ItemDecoration): Unit

Remove an ItemDecoration from this ViewPager2.

The given decoration will no longer impact the measurement and drawing of item views.

See also
`addItemDecoration`

removeItemDecorationAt

Added in 1.0.0

fun removeItemDecorationAt(index: Int): Unit

Removes the ItemDecoration associated with the supplied index position.

Parameters
`index: Int`	The index position of the ItemDecoration to be removed.

Throws
`java.lang.IndexOutOfBoundsException`	on invalid index

requestTransform

Added in 1.0.0

fun requestTransform(): Unit

Trigger a call to the registered PageTransformer's transformPage method. Call this when something has changed which has invalidated the transformations defined by the PageTransformer that did not trigger a page scroll.

Added in 1.0.0

fun setAdapter(adapter: RecyclerView.Adapter?): Unit

Set a new adapter to provide page views on demand.

If you're planning to use Fragments as pages, implement FragmentStateAdapter. If your pages are Views, implement RecyclerView.Adapter as usual.

If your pages contain LayoutTransitions, then those LayoutTransitions must have animateParentHierarchy set to false. Note that if you have a ViewGroup with animateLayoutChanges="true" in your layout xml file, a LayoutTransition is added automatically to that ViewGroup. You will need to manually call getLayoutTransition().setAnimateParentHierarchy(false) on that ViewGroup after you inflated the xml layout, like this:

View view = layoutInflater.inflate(R.layout.page, parent, false);
ViewGroup viewGroup = view.findViewById(R.id.animated_viewgroup);
viewGroup.getLayoutTransition().setAnimateParentHierarchy(false);

Parameters
`adapter: RecyclerView.Adapter?`	The adapter to use, or `null` to remove the current adapter

See also
`FragmentStateAdapter`
`setAdapter`

setCurrentItem

Added in 1.0.0

fun setCurrentItem(item: Int): Unit

Set the currently selected page. If the ViewPager has already been through its first layout with its current adapter there will be a smooth animated transition between the current item and the specified item. Silently ignored if the adapter is not set or empty. Clamps item to the bounds of the adapter.

Parameters
`item: Int`	Item index to select

setCurrentItem

Added in 1.0.0

fun setCurrentItem(item: Int, smoothScroll: Boolean): Unit

Set the currently selected page. If smoothScroll = true, will perform a smooth animation from the current item to the new item. Silently ignored if the adapter is not set or empty. Clamps item to the bounds of the adapter.

Parameters
`item: Int`	Item index to select
`smoothScroll: Boolean`	True to smoothly scroll to the new item, false to transition immediately

setLayoutDirection

fun setLayoutDirection(layoutDirection: Int): Unit

setOffscreenPageLimit

Added in 1.0.0

fun setOffscreenPageLimit(limit: Int): Unit

Set the number of pages that should be retained to either side of the currently visible page(s). Pages beyond this limit will be recreated from the adapter when needed. Set this to OFFSCREEN_PAGE_LIMIT_DEFAULT to use RecyclerView's caching strategy. The given value must either be larger than 0, or #OFFSCREEN_PAGE_LIMIT_DEFAULT.

Pages within limit pages away from the current page are created and added to the view hierarchy, even though they are not visible on the screen. Pages outside this limit will be removed from the view hierarchy, but the ViewHolders will be recycled as usual by RecyclerView.

This is offered as an optimization. If you know in advance the number of pages you will need to support or have lazy-loading mechanisms in place on your pages, tweaking this setting can have benefits in perceived smoothness of paging animations and interaction. If you have a small number of pages (3-4) that you can keep active all at once, less time will be spent in layout for newly created view subtrees as the user pages back and forth.

You should keep this limit low, especially if your pages have complex layouts. By default it is set to OFFSCREEN_PAGE_LIMIT_DEFAULT.

Parameters
`limit: Int`	How many pages will be kept offscreen on either side. Valid values are all values `>= 1` and `OFFSCREEN_PAGE_LIMIT_DEFAULT`

Throws
`java.lang.IllegalArgumentException`	If the given limit is invalid

See also
`getOffscreenPageLimit`

setOrientation

Added in 1.0.0

fun setOrientation(orientation: Int): Unit

Sets the orientation of the ViewPager2.

Parameters
`orientation: Int`	`ORIENTATION_HORIZONTAL` or `ORIENTATION_VERTICAL`

Added in 1.0.0

fun setPageTransformer(transformer: ViewPager2.PageTransformer?): Unit

Sets a PageTransformer that will be called for each attached page whenever the scroll position is changed. This allows the application to apply custom property transformations to each page, overriding the default sliding behavior.

Note: setting a PageTransformer disables data-set change animations to prevent conflicts between the two animation systems. Setting a null transformer will restore data-set change animations.

Parameters
`transformer: ViewPager2.PageTransformer?`	PageTransformer that will modify each page's animation properties

See also
`MarginPageTransformer`
`CompositePageTransformer`

setUserInputEnabled

Added in 1.0.0

fun setUserInputEnabled(enabled: Boolean): Unit

Enable or disable user initiated scrolling. This includes touch input (scroll and fling gestures) and accessibility input. Disabling keyboard input is not yet supported. When user initiated scrolling is disabled, programmatic scrolls through setCurrentItem still work. By default, user initiated scrolling is enabled.

Parameters
`enabled: Boolean`	`true` to allow user initiated scrolling, `false` to block user initiated scrolling

See also
`isUserInputEnabled`

Added in 1.0.0

fun unregisterOnPageChangeCallback(
    callback: ViewPager2.OnPageChangeCallback
): Unit

Remove a callback that was previously added via registerOnPageChangeCallback.

Parameters
`callback: ViewPager2.OnPageChangeCallback`	callback to remove
