public interface TimingTarget
This interface provides the methods which
are called by Animator during the course of a timing
sequence. Applications
that wish to receive timing events will either create a subclass
of TimingTargetAdapter and override or they can create or use
an implementation of TimingTarget. A TimingTarget can be passed
into the constructor of Animator or set later with the
Animator.addTarget(TimingTarget)
method. Any Animator may have multiple TimingTargets.-

timingEvent
void timingEvent(float fraction) This method will receive all of the timing events from an Animator during an animation. The fraction is the percent elapsed (0 to 1) of the current animation cycle.- Parameters:
fraction
- the fraction of completion between the start and end of the current cycle. Note that on reversing cycles (Animator.Direction.BACKWARD
) the fraction decreases from 1.0 to 0 on backwards-running cycles. Note also that animations with a duration ofINFINITE
will call timingEvent with an undefined value for fraction, since there is no fraction that makes sense if the animation has no defined length.- See Also:
