Known Direct Subclasses

Interpolator

An interpolator defines the rate of change of an animation.

Known Indirect Subclasses

AccelerateDecelerateInterpolator, AccelerateInterpolator, AnticipateInterpolator, AnticipateOvershootInterpolator, BaseInterpolator, BounceInterpolator, CycleInterpolator, DecelerateInterpolator, LinearInterpolator, OvershootInterpolator, PathInterpolator

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.
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.
BaseInterpolator	An abstract class which is extended by default interpolators.
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.
LinearInterpolator	An interpolator where the rate of change is constant
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)`.

A time interpolator defines the rate of change of an animation. This allows animations to have non-linear motion, such as acceleration and deceleration.

Summary

Public methods
abstract Float	`getInterpolation(input: Float)` Maps a value representing the elapsed fraction of an animation to a value that represents the interpolated fraction.

getInterpolation

Added in API level 11

abstract fun getInterpolation(input: Float): Float

Maps a value representing the elapsed fraction of an animation to a value that represents the interpolated fraction. This interpolated value is then multiplied by the change in value of an animation to derive the animated value at the current elapsed animation time.

Parameters
`input`	Float: A value between 0 and 1.0 indicating our current point in the animation where 0 represents the start and 1.0 represents the end

Return
`Float`	The interpolation value. This value can be more than 1.0 for interpolators which overshoot their targets, or less than 0 for interpolators that undershoot their targets.
