Interface Interpolator

All Known Implementing Classes:

AccelerateDecelerateInterpolator, AccelerateInterpolator, CycleInterpolator, DecelerateInterpolator, LinearInterpolator

public interface Interpolator

An interpolator defines the rate of change of an animation. This allows the basic animation effects (alpha, scale, translate, rotate) to be accelerated, decelerated, repeated, etc.

Method Summary

float

getInterpolation(float input) Maps a point on the timeline to a multiplier to be applied to the transformations of an animation.

Method Detail

getInterpolation

float getInterpolation(float input)

Maps a point on the timeline to a multiplier to be applied to the transformations of an animation.

Parameters:

input - 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:

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.
