AnticipateInterpolator

class AnticipateInterpolator : Interpolator


An interpolator where the change starts backward then flings forward.

Summary

Public constructors

Creates a new instance of AnticipateInterpolator.

Creates a new instance of AnticipateInterpolator.

Creates a new instance of AnticipateInterpolator from XML.

Public functions

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

Maps a value representing the elapsed fraction of an animation to a value that represents the interpolated fraction.

Public constructors

AnticipateInterpolator

AnticipateInterpolator()

Creates a new instance of AnticipateInterpolator.

AnticipateInterpolator

AnticipateInterpolator(tension: Float)

Creates a new instance of AnticipateInterpolator.

Parameters
tension: Float

Amount of anticipation. When tension equals 0.0f, there is no anticipation and the interpolator becomes a simple acceleration interpolator.

AnticipateInterpolator

AnticipateInterpolator(context: Context, attrs: AttributeSet?)

Creates a new instance of AnticipateInterpolator from XML.

Parameters
context: Context

The context.

attrs: AttributeSet?

The AttributeSet from the XML.

Public functions

getInterpolation

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