LeanbackViewPager

A viewpager with touch and key event handling disabled by default.

Layout manager that allows the user to flip left and right through pages of data. You supply an implementation of a PagerAdapter to generate the pages that the view shows.

ViewPager is most often used in conjunction with android.app.Fragment, which is a convenient way to supply and manage the lifecycle of each page. There are standard adapters implemented for using fragments with the ViewPager, which cover the most common use cases. These are androidx.fragment.app.FragmentPagerAdapter and androidx.fragment.app.FragmentStatePagerAdapter; each of these classes have simple code showing how to build a full user interface with them.

Views which are annotated with the DecorView annotation are treated as part of the view pagers 'decor'. Each decor view's position can be controlled via its android:layout_gravity attribute. For example:

<androidx.viewpager.widget.ViewPager
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <androidx.viewpager.widget.PagerTitleStrip
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_gravity="top" />

</androidx.viewpager.widget.ViewPager>

For more information about how to use ViewPager, read Creating Swipe Views with Tabs.

You can find examples of using ViewPager in the API 4+ Support Demos and API 13+ Support Demos sample code.

Summary

Nested types
`@Retention(value = RetentionPolicy.RUNTIME) @Target(value = ElementType.TYPE) @Inherited public annotation ViewPager.DecorView` Annotation which allows marking of views to be decoration views when added to a view pager.
`public class ViewPager.LayoutParams extends ViewGroup.LayoutParams` Layout parameters that should be supplied for views added to a ViewPager.
`public interface ViewPager.OnAdapterChangeListener` Callback interface for responding to adapter changes.
`public interface ViewPager.OnPageChangeListener` Callback interface for responding to changing state of the selected page.
`public interface ViewPager.PageTransformer` A PageTransformer is invoked whenever a visible/attached page is scrolled.
`public class ViewPager.SavedState extends AbsSavedState` This is the persistent state that is saved by ViewPager.
`public class ViewPager.SimpleOnPageChangeListener implements ViewPager.OnPageChangeListener` Simple implementation of the `OnPageChangeListener` interface with stub implementations of each method.

Constants
`static final int`	`SCROLL_STATE_DRAGGING = 1` Indicates that the pager is currently being dragged by the user.
`static final int`	`SCROLL_STATE_IDLE = 0` Indicates that the pager is in an idle, settled state.
`static final int`	`SCROLL_STATE_SETTLING = 2` Indicates that the pager is in the process of settling to a final position.

Indicates that the pager is currently being dragged by the user.

SCROLL_STATE_IDLE

Added in 1.1.0

public static final int SCROLL_STATE_IDLE = 0

Indicates that the pager is in an idle, settled state. The current page is fully in view and no animation is in progress.

Indicates that the pager is in the process of settling to a final position.

Public constructors

ViewPager

Added in 1.1.0

public ViewPager(@NonNull Context context)

ViewPager

Added in 1.1.0

public ViewPager(@NonNull Context context, @Nullable AttributeSet attrs)

Public methods

addFocusables

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

We only want the current page that is being shown to be focusable.

Added in 1.1.0

public void addOnAdapterChangeListener(
    @NonNull ViewPager.OnAdapterChangeListener listener
)

Add a listener that will be invoked whenever the adapter for this ViewPager changes.

Parameters
`@NonNull ViewPager.OnAdapterChangeListener listener`	listener to add

Added in 1.1.0

public void addOnPageChangeListener(
    @NonNull ViewPager.OnPageChangeListener listener
)

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

Components that add a listener should take care to remove it when finished. Other components that take ownership of a view may call clearOnPageChangeListeners to remove all attached listeners.

Parameters
`@NonNull ViewPager.OnPageChangeListener listener`	listener to add

addTouchables

public void addTouchables(ArrayList<View> views)

We only want the current page that is being shown to be touchable.

addView

public void addView(View child, int index, ViewGroup.LayoutParams params)

arrowScroll

Added in 1.1.0

public boolean arrowScroll(int direction)

Handle scrolling in response to a left or right arrow click.

Parameters
`int direction`	The direction corresponding to the arrow key that was pressed. It should be either `FOCUS_LEFT` or `FOCUS_RIGHT`.

Returns
`boolean`	Whether the scrolling was handled successfully.

beginFakeDrag

Added in 1.1.0

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 ViewPager with the touch scrolling of another view, while still letting the ViewPager 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.

During a fake drag the ViewPager will ignore all touch events. If a real 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`

canScrollHorizontally

public boolean canScrollHorizontally(int direction)

Check if this ViewPager can be scrolled horizontally in a certain direction.

Parameters
`int item`	Item index to select

setCurrentItem

Added in 1.1.0

public void setCurrentItem(int item, boolean smoothScroll)

Set the currently selected page.

Parameters
`int item`	Item index to select

setDragInGutterEnabled

Added in 1.1.0

public void setDragInGutterEnabled(boolean enabled)

Set whether ViewPager should consume drag events if they are within the gutter (left and right edges) of the ViewPager. The default value false.

Parameters
`boolean enabled`	true if ViewPager should allow drag in gutter, false otherwise

setOffscreenPageLimit

Added in 1.1.0

public void setOffscreenPageLimit(int limit)

Set the number of pages that should be retained to either side of the current page in the view hierarchy in an idle state. Pages beyond this limit will be recreated from the adapter when needed.

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. This setting defaults to 1.

Parameters
`int limit`	How many pages will be kept offscreen in an idle state.

Added in 1.1.0

Deprecated in 1.1.0

public void setOnPageChangeListener(ViewPager.OnPageChangeListener listener)

Set a listener that will be invoked whenever the page changes or is incrementally scrolled. See OnPageChangeListener.

Parameters
`ViewPager.OnPageChangeListener listener`	Listener to set

setPageMargin

Added in 1.1.0

public void setPageMargin(int marginPixels)

Set the margin between pages.

Parameters
`int marginPixels`	Distance between adjacent pages in pixels

See also
`getPageMargin`
`setPageMarginDrawable`
`setPageMarginDrawable`

setPageMarginDrawable

Added in 1.1.0

public void setPageMarginDrawable(@Nullable Drawable d)

Set a drawable that will be used to fill the margin between pages.

Parameters
`@Nullable Drawable d`	Drawable to display between pages

setPageMarginDrawable

Added in 1.1.0

public void setPageMarginDrawable(@DrawableRes int resId)

Set a drawable that will be used to fill the margin between pages.

Parameters
`@DrawableRes int resId`	Resource ID of a drawable to display between pages

Added in 1.1.0

public void setPageTransformer(
    boolean reverseDrawingOrder,
    @Nullable ViewPager.PageTransformer transformer
)

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: By default, calling this method will cause contained pages to use LAYER_TYPE_HARDWARE. This layer type allows custom alpha transformations, but it will cause issues if any of your pages contain a android.view.SurfaceView and you have not called setZOrderOnTop to put that android.view.SurfaceView above your app content. To disable this behavior, call setPageTransformer and pass LAYER_TYPE_NONE for pageLayerType.

Parameters
`boolean reverseDrawingOrder`	true if the supplied PageTransformer requires page views to be drawn from last to first instead of first to last.
`@Nullable ViewPager.PageTransformer transformer`	PageTransformer that will modify each page's animation properties

Added in 1.1.0

public void setPageTransformer(
    boolean reverseDrawingOrder,
    @Nullable ViewPager.PageTransformer transformer,
    int pageLayerType
)

Parameters
`boolean reverseDrawingOrder`	true if the supplied PageTransformer requires page views to be drawn from last to first instead of first to last.
`@Nullable ViewPager.PageTransformer transformer`	PageTransformer that will modify each page's animation properties
`int pageLayerType`	View layer type that should be used for ViewPager pages. It should be either `LAYER_TYPE_HARDWARE`, `LAYER_TYPE_SOFTWARE`, or `LAYER_TYPE_NONE`.

Protected methods

canScroll

Added in 1.1.0

protected boolean canScroll(@NonNull View v, boolean checkV, int dx, int x, int y)

Tests scrollability within child views of v given a delta of dx.

Parameters
`@NonNull View v`	View to test for horizontal scrollability
`boolean checkV`	Whether the view v passed should itself be checked for scrollability (true), or just its children (false).
`int dx`	Delta scrolled in pixels
`int x`	X coordinate of the active touch point
`int y`	Y coordinate of the active touch point

Returns
`boolean`	true if child views of v can be scrolled by delta of dx.

Parameters
`int position`	Position index of the first page currently being displayed. Page position+1 will be visible if positionOffset is nonzero.
`float offset`	Value from [0, 1) indicating the offset from the page at position.
`int offsetPixels`	Value in pixels indicating the offset from position.

onRequestFocusInDescendants

protected boolean onRequestFocusInDescendants(int direction, Rect previouslyFocusedRect)

We only want the current page that is being shown to be focusable.
