↳ | androidx.core.animation.DecelerateInterpolator |

Constructor
Parameters | |
---|---|
factor |
float : Degree to which the animation should be eased. Setting factor to 1.0f produces
an upside-down y=x^2 parabola. Increasing factor above 1.0f makes exaggerates the
ease-out effect (i.e., it starts even faster and ends evens slower)

Public methods
getInterpolation
public float getInterpolation (float input)
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 |
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 endValue is between 0.0 and 1.0 inclusive. |
Returns | |
---|---|
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.
Value is between 0.0 and 1.0 inclusive. |
