使用Calendar类

/**Calendar类中的.get(Calendar.DAY_OF_WEEK)可以获取当前日期是星期几

* 获取当前日期是星期几<br>

*

* @param dt

* @return 当前日期是星期几

*/

public static String getWeekOfDate(Date dt) {

String[] weekDays = {"星期日", "星期一", "星期二", "星期三", "星期四", "星期五", "星期六"}

Calendar cal = Calendar.getInstance()

cal.setTime(dt)

int w = cal.get(Calendar.DAY_OF_WEEK) - 1

if (w <0)

w = 0

return weekDays[w]

}
