淘宝抢购倒计时（时、分、秒）

private Runnable timeRunnable = new Runnable() {

        @Override
        public void run() {
            toDataCount();
        }

    };

private void toDataCount() {
 SimpleDateFormat df = new SimpleDateFormat("MM-dd HH:mm:ss");
        
        try {
            String date = df.format(new Date());
            Date d2 = df.parse(date);//系统时间
            Date d1 = df.parse(AppConfig.getTmLongToStr_(gameInfo.getStartDateUnix() * 1000));//服务器获取时间
           long  diff = d1.getTime() - d2.getTime();//这样得到的差值是微秒级别
           
            long days = diff / (1000 * 60 * 60 * 24);
            long hours = (diff - days * (1000 * 60 * 60 * 24)) / (1000 * 60 * 60);
            long minutes = (diff - days * (1000 * 60 * 60 * 24) - hours * (1000 * 60 * 60)) / (1000 * 60);
            long second = (diff - days * (1000 * 60 * 60 * 24) - hours * (1000 * 60 * 60) - minutes * (1000 * 60)) / 1000;


            if (days <= 0 && hours <= 0 && minutes <= 0 & second <= 0) {           
                time_tv.setText(hours + ":" + minutes + ":" + second);
                handler.removeCallbacks(timeRunnable);
            } else {
                time_tv.setText(hours + ":" + minutes + ":" + second);
                handler.postDelayed(timeRunnable, 1000);
            }
            
        } catch (Exception e) {
        }
}

 handler.post(timeRunnable);//调用倒计时
