AccelerateDecelerateInterpolator

class AccelerateDecelerateInterpolator : Interpolator


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

@FloatRange(from = 0, to = 1) Float

getInterpolation

fun getInterpolation(input: @FloatRange(from = 0, to = 1) Float): @FloatRange(from = 0, to = 1) 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: @FloatRange(from = 0, to = 1) 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

Returns
@FloatRange(from = 0, to = 1) 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.
