Usage

From source file:com.givewaygames.transition.Transition.java

/**
 * This method is called automatically by the Transition and
 * TransitionSet classes when a transition finishes, either because
 * a transition did nothing (returned a null Animator from
 * {@link com.hirevue.manager.tmp.transition.Transition#createAnimator(android.view.ViewGroup, android.transition.TransitionValues,
 * android.transition.TransitionValues)}) or because the transition returned a valid
 * Animator and end() was called in the onAnimationEnd()
 * callback of the AnimatorListener./*  ww  w  .j  av  a  2  s. c o m*/
 *
 * @hide
