Interfaces

AnimatorListener	An animation listener receives notifications from an animation.
AnimatorPauseListener	A pause listener receives notifications from an animation when the animation is `paused` or `resumed`.
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`.
Interpolator	An interpolator defines the rate of change of an animation.
TimeListener	Implementors of this interface can set themselves as update listeners to a `TimeAnimator` instance to receive callbacks on every animation frame to receive the total time since the animator started and the delta time since the last frame.
TypeEvaluator	Interface for use with the `ValueAnimator#setEvaluator(TypeEvaluator)` function.

Classes

AccelerateDecelerateInterpolator	An interpolator where the rate of change starts and ends slowly but accelerates through the middle.
AccelerateInterpolator	An interpolator where the rate of change starts out slowly and and then accelerates.
Animator	This is the superclass for classes which provide basic support for animations which can be started, ended, and have `AnimatorListeners` added to them.
AnimatorInflater	This class is used to instantiate animator XML files into Animator objects.
AnimatorListenerAdapter	This adapter class provides empty implementations of the methods from `Animator.AnimatorListener`.
AnimatorSet	This class plays a set of `Animator` objects in the specified order.
AnimatorTestRule	JUnit `TestRule` that can be used to run `Animator`s without actually waiting for the duration of the animation.
AnticipateInterpolator	An interpolator where the change starts backward then flings forward.
AnticipateOvershootInterpolator	An interpolator where the change starts backward then flings forward and overshoots the target value and finally goes back to the final value.
ArgbEvaluator	This evaluator can be used to perform type interpolation between integer values that represent ARGB colors.
BidirectionalTypeConverter	Abstract base class used convert type T to another type V and back again.
BounceInterpolator	An interpolator where the change bounces at the end.
CycleInterpolator	Repeats the animation for a specified number of cycles.
DecelerateInterpolator	An interpolator where the rate of change starts out quickly and and then decelerates.
FloatArrayEvaluator	This evaluator can be used to perform type interpolation between `float[]` values.
FloatEvaluator	This evaluator can be used to perform type interpolation between `float` values.
FloatProperty	An implementation of `android.util.Property` to be used specifically with fields of type `float`.
IntArrayEvaluator	This evaluator can be used to perform type interpolation between `int[]` values.
IntEvaluator	This evaluator can be used to perform type interpolation between `int` values.
IntProperty	An implementation of `android.util.Property` to be used specifically with fields of type `int`.
Keyframe	This class holds a time/value pair for an animation.
LinearInterpolator	An interpolator where the rate of change is constant
ObjectAnimator	This subclass of `ValueAnimator` provides support for animating properties on target objects.
OvershootInterpolator	An interpolator where the change flings forward and overshoots the last value then comes back.
PathInterpolator	An interpolator that can traverse a Path that extends from `Point(0, 0)` to `(1, 1)`.
PointFEvaluator	This evaluator can be used to perform type interpolation between `PointF` values.
PropertyValuesHolder	This class holds information about a property and the values that that property should take on during an animation.
RectEvaluator	This evaluator can be used to perform type interpolation between `Rect` values.
TimeAnimator	This class provides a simple callback mechanism to listeners that is synchronized with all other animators in the system.
TypeConverter	Abstract base class used convert type T to another type V.
ValueAnimator	This class provides a simple timing engine for running animations which calculate animated values and set them on target objects.

Extension functions summary

For android.animation.Animator
AnimatorListener	`Animator.addListener(crossinline onEnd: (animator: Animator) -> Unit = {}, crossinline onStart: (animator: Animator) -> Unit = {}, crossinline onCancel: (animator: Animator) -> Unit = {}, crossinline onRepeat: (animator: Animator) -> Unit = {})` Add a listener to this Animator using the provided actions.
AnimatorPauseListener	`Animator.addPauseListener(crossinline onResume: (animator: Animator) -> Unit = {}, crossinline onPause: (animator: Animator) -> Unit = {})` Add a pause and resume listener to this Animator using the provided actions.
AnimatorListener	`Animator.doOnCancel(crossinline action: (animator: Animator) -> Unit)` Add an action which will be invoked when the animation has been cancelled.
AnimatorListener	`Animator.doOnEnd(crossinline action: (animator: Animator) -> Unit)` Add an action which will be invoked when the animation has ended.
AnimatorPauseListener	`Animator.doOnPause(crossinline action: (animator: Animator) ->`
