Public Constructors

public AnticipateInterpolator ()

Added in API level 4

public AnticipateInterpolator (float tension)

Added in API level 4

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

public AnticipateInterpolator (Context context, AttributeSet attrs)

Added in API level 4

Public Methods

public float getInterpolation (float t)

Added in API level 4

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
t 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
  • 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.
