DecelerateInterpolator

public class DecelerateInterpolator
extends Object implements Interpolator

java.lang.Object
   ↳ androidx.core.animation.DecelerateInterpolator


An interpolator where the rate of change starts out quickly and and then decelerates.

Summary

Public constructors

DecelerateInterpolator()
DecelerateInterpolator(float factor)

Constructor

DecelerateInterpolator(Context context, AttributeSet attrs)

Public methods

float getInterpolation(float input)

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

DecelerateInterpolator

public DecelerateInterpolator (float factor)

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 end

Value 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.
