使用ThreadFactory在队列中堆栈Runnables

Question

我有一个方法需要4秒才能执行，如果用户在结束之前再次调用它而不是刷新，我想只在最后一个完成后启动新的，将它们放入队列中。 / p>

我已经阅读了documentation，但我仍然不知道如何实现它，有人可以提供一个例子吗？

代码

我的方法：

    public void popClassAdded(int amount){

    classAddedText.setText(getString(R.string.you_earned) + amount + " ");
    setIn = new AnimatorSet();
    setIn.playTogether(
            Glider.glide(Skill.QuintEaseOut, 200, ObjectAnimator.ofFloat(classAddedLayout, "translationY", -50, 165))
    );
    setIn.setDuration(1200);
    classAddedLayout.setVisibility(View.VISIBLE);
    setIn.start();
    classAddedLayout.postDelayed(new Runnable(){
        public void run(){
            AnimatorSet set = new AnimatorSet();
            set.playTogether(Glider.glide(Skill.CubicEaseInOut, 200, ObjectAnimator.ofFloat(classAddedLayout, "translationY", 165, -50)));
            set.setDuration(1200);
            set.start();
            set.addListener(new Animator.AnimatorListener() {
                @Override
                public void onAnimationStart(Animator animation) {                    }
                @Override
                public void onAnimationEnd(Animator animation) {
                    classAddedLayout.setVisibility(View.GONE);
                }
                @Override
                public void onAnimationCancel(Animator animation) {                  }
                @Override
                public void onAnimationRepeat(Animator animation) {                    }
            });
        }
    },2000);

    shopPrefs.edit().putInt("coins", amount + shopPrefs.getInt("coins", 0)).apply();

}

致电：

    add.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                //may get clicked more than once in an interval or 4 seconds
                ((Activity_Main)getActivity()).popClassAdded(100);
            }
        });
