androidx.core.animation

An animation listener receives notifications from an animation.

A pause listener receives notifications from an animation when the animation is paused or resumed.

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.

An interpolator defines the rate of change of an animation.

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.

Interface for use with the setEvaluator function.

An interpolator where the rate of change starts and ends slowly but accelerates through the middle.

An interpolator where the rate of change starts out slowly and then accelerates.

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

This class is used to instantiate animator XML files into Animator objects.

This adapter class provides empty implementations of the methods from Animator.AnimatorListener.

This class plays a set of Animator objects in the specified order.

The Builder object is a utility class to facilitate adding animations to a AnimatorSet along with the relationships between the various animations.

JUnit TestRule that can be used to run Animators without actually waiting for the duration of the animation.

An interpolator where the change starts backward then flings forward.

An interpolator where the change starts backward then flings forward and overshoots the target value and finally goes back to the final value.

This evaluator can be used to perform type interpolation between integer values that represent ARGB colors.

Abstract base class used convert type T to another type V and back again.

An interpolator where the change bounces at the end.

Repeats the animation for a specified number of cycles.

An interpolator where the rate of change starts out quickly and then decelerates.

This evaluator can be used to perform type interpolation between float[] values.

This evaluator can be used to perform type interpolation between float values.

An implementation of android.util.Property to be used specifically with fields of type float.

This evaluator can be used to perform type interpolation between int[] values.

This evaluator can be used to perform type interpolation between int values.

An implementation of android.util.Property to be used specifically with fields of type int.

This class holds a time/value pair for an animation.

An interpolator where the rate of change is constant

This subclass of ValueAnimator provides support for animating properties on target objects.

An interpolator where the change flings forward and overshoots the last value then comes back.

An interpolator that can traverse a Path that extends from Point(0, 0) to (1, 1).

This evaluator can be used to perform type interpolation between PointF values.

This class holds information about a property and the values that that property should take on during an animation.

This evaluator can be used to perform type interpolation between Rect values.

This class provides a simple callback mechanism to listeners that is synchronized with all other animators in the system.

Abstract base class used convert type T to another type V.

This class provides a simple timing engine for running animations which calculate animated values and set them on target objects.
