ViewPager2

Kotlin |Java

public final class ViewPager2
extends ViewGroup

java.lang.Object
↳	android.view.View
	↳	android.view.ViewGroup
		↳	androidx.viewpager2.widget.ViewPager2

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

Summary

Nested classes
`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
`int`	`OFFSCREEN_PAGE_LIMIT_DEFAULT` 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.
`int`	`ORIENTATION_HORIZONTAL`
`int`	`ORIENTATION_VERTICAL`
`int`	`SCROLL_STATE_DRAGGING` Indicates that the ViewPager2 is currently being dragged by the user, or programmatically via fake drag functionality.
`int`	`SCROLL_STATE_IDLE` Indicates that the ViewPager2 is in an idle, settled state.
`int`	`SCROLL_STATE_SETTLING` Indicates that the ViewPager2 is in the process of settling to a final position.

Public methods

public void addItemDecoration (RecyclerView.ItemDecoration decor)

Add an RecyclerView.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

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

Add an RecyclerView.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
`IndexOutOfBoundsException`	on indexes larger than `getItemDecorationCount()`

beginFakeDrag

public boolean beginFakeDrag ()

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(float) 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(boolean). 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

See also:

canScrollHorizontally

public boolean canScrollHorizontally (int direction)

Parameters
`direction`	`int`

Returns
`boolean`

canScrollVertically

public boolean canScrollVertically (int direction)

Parameters
`direction`	`int`

Returns
`boolean`

endFakeDrag

public boolean endFakeDrag ()

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:

fakeDragBy

public boolean fakeDragBy (float offsetPxFloat)

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`	`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.

See also:

getAccessibilityClassName

public CharSequence getAccessibilityClassName ()

Returns
`CharSequence`

getAdapter

public Adapter getAdapter ()

Returns
`Adapter`

getCurrentItem

public int getCurrentItem ()

Returns the currently selected page. If no page can sensibly be selected because there is no adapter or the adapter is empty, returns 0.

Returns
`int`	Currently selected page

getItemDecorationAt

public RecyclerView.ItemDecoration getItemDecorationAt (int index)

Returns an RecyclerView.ItemDecoration previously added to this ViewPager2.

Parameters
`index`	`int`: The index position of the desired ItemDecoration.

Returns
`RecyclerView.ItemDecoration`	the ItemDecoration at index position

Throws
`IndexOutOfBoundsException`	on invalid index

getItemDecorationCount

public int getItemDecorationCount ()

Returns the number of RecyclerView.ItemDecoration currently added to this ViewPager2.

Returns
`int`	number of ItemDecorations currently added added to this ViewPager2.

getOffscreenPageLimit

public int getOffscreenPageLimit ()

Returns the number of pages that will be retained to either side of the current page in the view hierarchy in an idle state. Defaults to OFFSCREEN_PAGE_LIMIT_DEFAULT.

Returns
`int`	How many pages will be kept offscreen on either side

See also:

setOffscreenPageLimit(int)

getOrientation

public int getOrientation ()

Returns
`int`

getScrollState

public int getScrollState ()

Returns the current scroll state of the ViewPager2. Returned value is one of can be one of SCROLL_STATE_IDLE, SCROLL_STATE_DRAGGING or SCROLL_STATE_SETTLING.

Returns
`int`	The scroll state that was last dispatched to `ViewPager2.OnPageChangeCallback.onPageScrollStateChanged(int)`

invalidateItemDecorations

public void invalidateItemDecorations ()

Invalidates all ItemDecorations. If ViewPager2 has item decorations, calling this method will trigger a View.requestLayout() call.

isFakeDragging

public boolean isFakeDragging ()

Returns true if a fake drag is in progress.

Returns
`boolean`	`true` if currently in a fake drag, `false` otherwise.

See also:

isUserInputEnabled

public boolean isUserInputEnabled ()

Returns if user initiated scrolling between pages is enabled. Enabled by default.

Returns
`boolean`	`true` if users can scroll the ViewPager2, `false` otherwise

See also:

setUserInputEnabled(boolean)

onInitializeAccessibilityNodeInfo

public void onInitializeAccessibilityNodeInfo (AccessibilityNodeInfo info)

Parameters
`info`	`AccessibilityNodeInfo`

onViewAdded

public void onViewAdded (View child)

Parameters
`child`	`View`

performAccessibilityAction

public boolean performAccessibilityAction (int action, 
                Bundle arguments)

Parameters
`action`	`int`
`arguments`	`Bundle`

Returns
`boolean`

public void registerOnPageChangeCallback (ViewPager2.OnPageChangeCallback callback)

Add a callback that will be invoked whenever the page changes or is incrementally scrolled. See ViewPager2.OnPageChangeCallback.

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

Parameters
`callback`	`ViewPager2.OnPageChangeCallback`: callback to add

public void removeItemDecoration (RecyclerView.ItemDecoration decor)

Remove an RecyclerView.ItemDecoration from this ViewPager2.

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

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

See also:

addItemDecoration(ItemDecoration)

removeItemDecorationAt

public void removeItemDecorationAt (int index)

Removes the RecyclerView.ItemDecoration associated with the supplied index position.

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

Throws
`IndexOutOfBoundsException`	on invalid index

requestTransform

public void requestTransform ()

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.

public void setAdapter (Adapter adapter)

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`	`Adapter`: The adapter to use, or `null` to remove the current adapter

See also:

setCurrentItem

public void setCurrentItem (int item)

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

public void setCurrentItem (int item, 
                boolean smoothScroll)

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

public void setLayoutDirection (int layoutDirection)

Parameters
`layoutDirection`	`int`

setOffscreenPageLimit

public void setOffscreenPageLimit (int limit)

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
`IllegalArgumentException`	If the given limit is invalid

See also:

getOffscreenPageLimit()

setOrientation

public void setOrientation (int orientation)

Sets the orientation of the ViewPager2.

Parameters
`orientation`	`int`: `ORIENTATION_HORIZONTAL` or `ORIENTATION_VERTICAL`

public void setPageTransformer (ViewPager2.PageTransformer transformer)

Sets a ViewPager2.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 ViewPager2.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:

setUserInputEnabled

public void setUserInputEnabled (boolean enabled)

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()

public void unregisterOnPageChangeCallback (ViewPager2.OnPageChangeCallback callback)

Remove a callback that was previously added via registerOnPageChangeCallback(OnPageChangeCallback).

Parameters
`callback`	`ViewPager2.OnPageChangeCallback`: callback to remove
