Animator

Kotlin |Java

abstract class Animator : Cloneable

kotlin.Any
↳	androidx.core.animation.Animator

Known Direct Subclasses

AnimatorSet, ValueAnimator

AnimatorSet	This class plays a set of `Animator` objects in the specified order.
ValueAnimator	This class provides a simple timing engine for running animations which calculate animated values and set them on target objects.

Known Indirect Subclasses

ObjectAnimator, TimeAnimator

ObjectAnimator	This subclass of `ValueAnimator` provides support for animating properties on target objects.
TimeAnimator	This class provides a simple callback mechanism to listeners that is synchronized with all other animators in the system.

This is the superclass for classes which provide basic support for animations which can be started, ended, and have AnimatorListeners added to them.

Summary

Nested classes
abstract	`AnimatorListener` An animation listener receives notifications from an animation.
abstract	`AnimatorPauseListener` A pause listener receives notifications from an animation when the animation is `paused` or `resumed`.
abstract	`AnimatorUpdateListener` Implementors of this interface can add themselves as update listeners to an `ValueAnimator` instance to receive callbacks on every animation frame, after the current frame's values have been calculated for that `ValueAnimator`.

Constants
static Long	`DURATION_INFINITE` The value used to indicate infinite duration (e.g. when Animators repeat infinitely).

Public constructors
`<init>()` This is the superclass for classes which provide basic support for animations which can be started, ended, and have `AnimatorListeners` added to them.

Public methods
open Unit	`addListener(@NonNull listener: Animator.AnimatorListener)` Adds a listener to the set of listeners that are sent events through the life of an animation, such as start, repeat, and end.
open Unit	`addPauseListener(@NonNull listener: Animator.AnimatorPauseListener)` Adds a pause listener to this animator.
open Unit	`addUpdateListener(@NonNull listener: Animator.AnimatorUpdateListener)` Adds a listener to the set of listeners that are sent update events through the life of an animation.
open Unit	`cancel()` Cancels the animation.
open Animator	`clone()`
open Unit	`end()` Ends the animation.
abstract Long	`getDuration()` Gets the duration of the animation.
open Interpolator?	`getInterpolator()` Returns the timing interpolator that this animation uses.
abstract Long	`getStartDelay()` The amount of time, in milliseconds, to delay processing the animation after `start()` is called.
open Long	`getTotalDuration()` Gets the total duration of the animation, accounting for animation sequences, start delay, and repeating.
open Boolean	`isPaused()` Returns whether this animator is currently in a paused state.
abstract Boolean	`isRunning()` Returns whether this Animator is currently running (having been started and gone past any initial startDelay period and not yet ended).
open Boolean	`isStarted()` Returns whether this Animator has been started and not yet ended.
open Unit	`pause()` Pauses a running animation.
open Unit	`removeAllListeners()` Removes all `listeners` and `pauseListeners` from this object.
open Unit	`removeAllUpdateListeners()` Removes all listeners from the set listening to frame updates for this animation.
open Unit	`removeListener(@NonNull listener: Animator.AnimatorListener)` Removes a listener from the set listening to this animation.
open Unit	`removePauseListener(@NonNull listener: Animator.AnimatorPauseListener)` Removes a pause listener from the set listening to this animation.
open Unit	`removeUpdateListener(@NonNull listener: Animator.AnimatorUpdateListener)` Removes a listener from the set listening to frame updates for this animation.
open Unit	`resume()` Resumes a paused animation, causing the animator to pick up where it left off when it was paused.
abstract Animator	`setDuration(@IntRange(0) duration: Long)` Sets the duration of the animation.
abstract Unit	`setInterpolator(@Nullable value: Interpolator?)` The interpolator used in calculating the elapsed fraction of the animation.
abstract Unit	`setStartDelay(@IntRange(0) startDelay: Long)` The amount of time, in milliseconds, to delay processing the animation after `start()` is called.
open Unit	`setTarget(@Nullable target: Any?)` Sets the target object whose property will be animated by this animation.
open Unit	`setupEndValues()` This method tells the object to use appropriate information to extract ending values for the animation.
open Unit	`setupStartValues()` This method tells the object to use appropriate information to extract starting values for the animation.
