AnticipateInterpolator


public class AnticipateInterpolator implements Interpolator


An interpolator where the change starts backward then flings forward.

Summary

Public constructors

Creates a new instance of AnticipateInterpolator.

AnticipateInterpolator(float tension)

Creates a new instance of AnticipateInterpolator.

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

Creates a new instance of AnticipateInterpolator from XML.

Public methods

@FloatRange(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

AnticipateInterpolator

public AnticipateInterpolator()

Creates a new instance of AnticipateInterpolator.

AnticipateInterpolator

public AnticipateInterpolator(float tension)

Creates a new instance of AnticipateInterpolator.

Parameters
float tension

Amount of anticipation. When tension equals 0.0f, there is no anticipation and the interpolator becomes a simple acceleration interpolator.

AnticipateInterpolator

public AnticipateInterpolator(
    @NonNull Context context,
    @Nullable AttributeSet attrs
)

Creates a new instance of AnticipateInterpolator from XML.

Parameters
@NonNull Context context

The context.

@Nullable AttributeSet attrs

The AttributeSet from the XML.

Public methods

getInterpolation

public @FloatRange(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(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.
