  Calendar c = Calendar.getInstance();  Date date = c.getTime();    String s = DateToWeek(date); Log.e("ssssss", "ssss" + s);  public static String[] WEEK = {"星期天","星期一","星期二","星期三","星期四","星期五","星期六"};    public static final int WEEKDAYS = 7;    public static String DateToWeek(Date date) {        Calendar calendar = Calendar.getInstance();        calendar.setTime(date);        int dayIndex = calendar.get(Calendar.DAY_OF_WEEK);        if (dayIndex < 1 || dayIndex > WEEKDAYS) {            return null;        }        return WEEK[dayIndex - 1];    }

这样就可以很简单的把当前的时间转化成星期几了!!
当然我们也可以通过这个类Calendar 得到当前的年月日小时,分钟,秒都可以得到下面看代码

         Calendar c = Calendar.getInstance();        Date date = c.getTime();        int year = c.get(Calendar.YEAR);        int month = c.get(Calendar.MONTH);//        int date = c.get(Calendar.DATE);        int hour = c.get(Calendar.HOUR_OF_DAY);        int minute = c.get(Calendar.MINUTE);        int second = c.get(Calendar.SECOND);
