Interface IInterpolator
interface IInterpolator
Extends com.amazon.apmf.IStandard
Interface for interpolating the progress of an animation.
This interface allows customizing the pace of an animation by defining how the
animation progresses.
The user is expected to implement or customize this interface to
define the desired interpolation behavior for their animation and set it
via IAnimatorBuilder::interpolator.
Methods
getInterpolation()
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 fraction of animation. For example, consider an animation that changes the opacity of IView from 0.0 (fully transparent) to 1.0 (fully opaque) over a duration of 2 seconds. If the elapsed fraction is 0.25, and the interpolator returns 0.6, the animated opacity value at that point would be 0.6, which is 60% of the total change (1.0 - 0.0 = 1.0).floatgetInterpolation(floatelapsedFraction)
Parameters
elapsedFraction
float — Required
A value between 0.0 and 1.0 indicating our current point in the
animation where 0.0 represents the start and 1.0 represents the end.
Returns
float
The interpolation value. This value can be more than 1.0
for interpolator which overshoot its target, or less than 0.0 for
interpolator that undershoot its target.
