获取星期几

public String getWeekOfDate(Date date) { 
        String[] weekDaysName = { "周日", "周一", "周二", "周三", "周四", "周五", "周六" }; 
        Calendar calendar = Calendar.getInstance(); 
        calendar.setTime(date); 
        int intWeek = calendar.get(Calendar.DAY_OF_WEEK) - 1; 
        return weekDaysName[intWeek]; 
    }

可以说 非常好用了
