何时调用AnimationListener的onPauseAnimation？

Question

何时调用AnimationListener的onPauseAnimation？我们如何使用onPauseAmimation来使用任何其他动画来执行和恢复以前的动画？

＆＃39;

animator.addListener(new AnimatorListenerAdapter() {
            @Override
            public void onAnimationStart(Animator animation) {
                Log.e("Testing : ", "onStart");
                super.onAnimationStart(animation);
            }

            @Override
            public void onAnimationEnd(Animator animation) {
                Log.e("Testing : ", "OnStop");

                super.onAnimationEnd(animation);
            }

            @Override
            public void onAnimationPause(Animator animation) {
                Log.e("Testing : ", "OnPause" + "it will never get called..");
                super.onAnimationPause(animation);
            }
        });
        animator.start();
