获取星期几的GregorianCalendar的 [英] Get day of the week from GregorianCalendar

问题描述

我有个约会，我需要知道星期几，所以我用一个GregorianCalendar对象，但我取回一些日期是不正确。

 的GregorianCalendar日历=新的GregorianCalendar（年，月，日）;
INT I = calendar.get（Calendar.DAY_OF_WEEK）;
 

我是什么做错了吗？

谢谢！

编辑答案：

  mont--;
GregorianCalendar的日历=新的GregorianCalendar（年，月，日）;
INT I = calendar.get（Calendar.DAY_OF_WEEK）;

    如果（ⅰ== 2）{
        dayOfTheWeek =星期一;
    }否则，如果（我== 3）{
        dayOfTheWeek =星期二;
    }否则，如果（我== 4）{
        dayOfTheWeek =星期三;
    }否则，如果（我== 5）{
        dayOfTheWeek =星期四;
    }否则，如果（我== 6）{
        dayOfTheWeek =星期五;
    }否则，如果（我== 7）{
        dayOfTheWeek =星期六;
    }否则如果（ⅰ== 1）{
        dayOfTheWeek =太阳报;
    }
 

解决方案

 时区时区= TimeZone.getDefault（）;
台历挂历=新的GregorianCalendar（时区）;
calendar.set（年，月，日，时，分，秒）;

串MONTHNAME = calendar.getDisplayName（Calendar.MONTH，Calendar.SHORT，Locale.getDefault（））; // Locale.US）;
串DAYNAME = calendar.getDisplayName（Calendar.DAY_OF_WEEK，Calendar.SHORT，Locale.getDefault（））; // Locale.US）;
 

I have a date and I need to know the day of the week, so I used a GregorianCalendar object but I get back some dates that are incorrect.

GregorianCalendar calendar = new GregorianCalendar(year, month, day);
int i = calendar.get(Calendar.DAY_OF_WEEK);

What am I doing wrong?

Thanks!

EDIT SOLUTION:

mont--;
GregorianCalendar calendar = new GregorianCalendar(year, month, day);
int i = calendar.get(Calendar.DAY_OF_WEEK);

    if(i == 2){
        dayOfTheWeek = "Mon";           
    } else if (i==3){
        dayOfTheWeek = "Tue";
    } else if (i==4){
        dayOfTheWeek = "Wed";
    } else if (i==5){
        dayOfTheWeek = "Thu";
    } else if (i==6){
        dayOfTheWeek = "Fri";
    } else if (i==7){
        dayOfTheWeek = "Sat";
    } else if (i==1){
        dayOfTheWeek = "Sun";
    }

解决方案

TimeZone timezone = TimeZone.getDefault();
Calendar calendar = new GregorianCalendar(timezone);
calendar.set(year, month, day, hour, minute, second);

String monthName=calendar.getDisplayName(Calendar.MONTH, Calendar.SHORT, Locale.getDefault());//Locale.US);
String dayName=calendar.getDisplayName(Calendar.DAY_OF_WEEK, Calendar.SHORT, Locale.getDefault());//Locale.US);
