用到的一些方法

public static List<CanBie> allCanbie = new ArrayList();

根据当前的时间与数据库表存储时间来判断餐别

public static CanBie getCurrentCanbie() {
        long hour = Calendar.getInstance().get(Calendar.HOUR_OF_DAY);
        long minutes = Calendar.getInstance().get(Calendar.MINUTE);
        long seconds = Calendar.getInstance().get(Calendar.SECOND);
        long now = hour * 60 * 60 + minutes * 60 + seconds;
        for (int i = 0; i < allCanbie.size(); i++) {
            CanBie cb = allCanbie.get(i);
            if (now > cb.CB_StartTime && now < cb.CB_EndTime) {
                return cb;
            }
        }
        return null;
    }
