AccelerateInterpolator

class AccelerateInterpolator : Interpolator


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

Summary

Public constructors

Creates a new instance of AccelerateInterpolator with y=x^2 parabola.

Creates a new instance of AccelerateInterpolator.

Creates a new instance of AccelerateInterpolator from XML.

Public functions

@FloatRange(from = 0, 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

AccelerateInterpolator

AccelerateInterpolator()

Creates a new instance of AccelerateInterpolator with y=x^2 parabola.

AccelerateInterpolator

AccelerateInterpolator(factor: Float)

Creates a new instance of AccelerateInterpolator.

Parameters
factor: Float

Degree to which the animation should be eased. Setting factor to 1.0f produces a y=x^2 parabola. Increasing factor above 1.0f exaggerates the ease-in effect (i.e., it starts even slower and ends evens faster)

AccelerateInterpolator

AccelerateInterpolator(context: Context, attrs: AttributeSet)

Creates a new instance of AccelerateInterpolator from XML.

Parameters
context: Context

The context.

attrs: AttributeSet

The AttributeSet from XML.

Public functions

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.
