Slice

Kotlin |Java

class Slice : Parcelable

kotlin.Any
↳	android.app.slice.Slice

A slice is a piece of app content and actions that can be surfaced outside of the app.

They are constructed using Builder in a tree structure that provides the OS some information about how the content should be displayed.

Summary

Nested classes
	`Builder` A Builder used to construct `Slice`s

Constants
static String	`EXTRA_RANGE_VALUE` Key to retrieve an extra added to an intent when the value of an input range is changed.
static String	`EXTRA_TOGGLE_STATE` Key to retrieve an extra added to an intent when a control is changed.
static String	`HINT_ACTIONS` Hint that this slice contains a number of actions that can be grouped together in a sort of controls area of the UI.
static String	`HINT_ERROR` A hint to indicate that this slice represents an error.
static String	`HINT_HORIZONTAL` Hint that list items within this slice or subslice would appear better if organized horizontally.
static String	`HINT_KEYWORDS` A hint to indicate that the contents of this subslice represent a list of keywords related to the parent slice.
static String	`HINT_LARGE` Hint that this content is important and should be larger when displayed if possible.
static String	`HINT_LAST_UPDATED` Hint indicating an item representing when the content was created or last updated.
static String	`HINT_LIST` Hint that all sub-items/sub-slices within this content should be considered to have `HINT_LIST_ITEM`.
static String	`HINT_LIST_ITEM` Hint that this item is part of a list and should be formatted as if is part of a list.
static String	`HINT_NO_TINT` Hint to indicate that this content should not be tinted.
static String	`HINT_PARTIAL` Hint to indicate that this slice is incomplete and an update will be sent once loading is complete.
static String	`HINT_PERMISSION_REQUEST` A hint to indicate that this slice represents a permission request for showing slices.
static String	`HINT_SEE_MORE` A hint representing that this item should be used to indicate that there's more content associated with this slice.
static String	`HINT_SELECTED` Hint indicating that this item (and its sub-items) are the current selection.
static String	`HINT_SHORTCUT` Hint to indicate that this content should only be displayed if the slice is presented as a shortcut.
static String	`HINT_SUMMARY` Hint indicating this content should be shown instead of the normal content when the slice is in small format.
static String	`HINT_TITLE` Hint that this content is a title of other content in the slice.
static String	`HINT_TTL` Hint indicating an item representing a time-to-live for the content.
static String	`SUBTYPE_COLOR` Subtype to tag an item as representing a color.
static String	`SUBTYPE_CONTENT_DESCRIPTION` Subtype to tag an item to use as a content description.
static String	`SUBTYPE_LAYOUT_DIRECTION` Subtype to indicate that this item indicates the layout direction for content in the slice.
static String	`SUBTYPE_MAX` Subtype to tag an item as representing the max int value for a `SUBTYPE_RANGE`.
static String	`SUBTYPE_MESSAGE` Subtype to indicate that this is a message as part of a communication sequence in this slice.
static String	`SUBTYPE_MILLIS` Subtype to tag an item as representing a time in milliseconds since midnight, January 1, 1970 UTC.
static String	`SUBTYPE_PRIORITY` Subtype to tag an item representing priority.
static String	`SUBTYPE_RANGE` Subtype to tag an item as representing a range.
static String	`SUBTYPE_SOURCE` Subtype to tag the source (i.e. sender) of a
static String	`SUBTYPE_TOGGLE` Subtype to indicate that this content has a toggle action associated with it.
static String	`SUBTYPE_VALUE` Subtype to tag an item as representing the current int value for a `SUBTYPE_RANGE`.

Inherited constants

From class Parcelable

Int

CONTENTS_FILE_DESCRIPTOR

Descriptor bit used with describeContents(): indicates that the Parcelable object's flattened representation includes a file descriptor.

Int

PARCELABLE_WRITE_RETURN_VALUE

Flag for use with writeToParcel: the object being written is a return value, that is the result of a function such as "Parcelable someFunction()", "void someFunction(out Parcelable)", or "void someFunction(inout Parcelable)". Some implementations may want to release resources at this point.

Protected constructors
`Slice(in: Parcel!)`

Public methods
Int	`describeContents()`
MutableList<String!>!	`getHints()`
MutableList<SliceItem!>!	`getItems()`
SliceSpec?	`getSpec()`
Uri!	`getUri()`
Boolean	`isCallerNeeded()` Returns whether the caller for this slice matters.
Unit	`writeToParcel(dest: Parcel, flags: Int)`

Properties
static Parcelable.Creator<Slice!>	`CREATOR`

Parameters
`dest`	Parcel: The Parcel in which the object should be written. This value cannot be `null`.
`flags`	Int: Additional flags about how the object should be written. May be 0 or `PARCELABLE_WRITE_RETURN_VALUE`. Value is either `0` or a combination of `android.os.Parcelable#PARCELABLE_WRITE_RETURN_VALUE`, and android.os.Parcelable.PARCELABLE_ELIDE_DUPLICATES
