AccelerateInterpolator

public class AccelerateInterpolator
extends Object implements Interpolator

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


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

Summary

Public constructors

AccelerateInterpolator()

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

AccelerateInterpolator(float factor)

Creates a new instance of AccelerateInterpolator.

AccelerateInterpolator(Context context, AttributeSet attrs)

Creates a new instance of AccelerateInterpolator from XML.

Public methods

float getInterpolation(float input)

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

Inherited methods

Public constructors

AccelerateInterpolator

public AccelerateInterpolator ()

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

AccelerateInterpolator

public AccelerateInterpolator (float factor)

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

public AccelerateInterpolator (Context context, 
                AttributeSet attrs)

Creates a new instance of AccelerateInterpolator from XML.

Parameters
context Context: The context.

attrs AttributeSet: The AttributeSet from XML.

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.
