DecelerateInterpolator

public class DecelerateInterpolator implements Interpolator


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

Summary

Public constructors

DecelerateInterpolator(float factor)

Constructor

DecelerateInterpolator(
    @NonNull Context context,
    @Nullable AttributeSet attrs
)

Public methods

@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 DecelerateInterpolator(float factor)

Constructor

Parameters
float factor

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 @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(from = 0, to = 1) 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.
