interface TimeInterpolator

android.animation.TimeInterpolator

Known Direct Subclasses Interpolator 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.

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.
