AccelerateInterpolator

public class AccelerateInterpolator implements Interpolator


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

Summary

Public constructors

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

AccelerateInterpolator(float factor)

Creates a new instance of AccelerateInterpolator.

AccelerateInterpolator(
    @NonNull Context context,
    @NonNull AttributeSet attrs
)

Creates a new instance of AccelerateInterpolator from XML.

Public methods

@Override @FloatRange(from = 0, to = 1) float
getInterpolation(@FloatRange(from = 0, to = 1) float input)

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

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
float factor

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(
    @NonNull Context context,
    @NonNull AttributeSet attrs
)

Creates a new instance of AccelerateInterpolator from XML.

Parameters
@NonNull Context context

The context.

@NonNull AttributeSet attrs

The AttributeSet from XML.

Public methods

getInterpolation

@Override
public @FloatRange(from = 0, to = 1) float getInterpolation(@FloatRange(from = 0, to = 1) 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
@FloatRange(from = 0, to = 1) float 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
@FloatRange(f
