Calendar.WEEK_OF_MONTH在两个不同的设备上提供不同的结果

Question

我有两个设备HTC与Android 2.3.5和三星与2.3.6现在我面临的问题是我需要日期的一个月的一周.

所以我写了这段代码并安装在两部手机上.并将系统日期设置为

2013年1月27日

  Calendar calendar = Calendar.getInstance();
  int weekOfMonth =  calendar.get(Calendar.WEEK_OF_MONTH);
  Log.i(TAG,"weekOfMonth = "+weekOfMonth);

现在关于HTC的输出是

 weekOfMonth = 5

而在三星运行相同的代码产生

 weekOfMonth = 4

这真的是搞砸了我的逻辑计算.

难道我做错了什么 ？

Answer 1

这可能是由于Locales.在Java中

        Calendar calFr = Calendar.getInstance(TimeZone.getTimeZone("Europe/Paris"), Locale.FRANCE);
        Calendar calUs = Calendar.getInstance(TimeZone.getTimeZone("US/Eastern"), Locale.US);
        Calendar calUk = Calendar.getInstance(TimeZone.getTimeZone("GMT"), Locale.UK);
        calFr.set(2013, Calendar.JANUARY, 27);
        calUs.set(2013, Calendar.JANUARY, 27);
        calUk.set(2013, Calendar.JANUARY, 27);

        int weekOfMonthFr = calFr.get(Calendar.WEEK_OF_MONTH);
        int weekOfMonthUs = calUs.get(Calendar.WEEK_OF_MONTH);
        int weekOfMonthUk = calUk.get(Calendar.WEEK_OF_MONTH);
        System.out.println("France week of month is " + weekOfMonthFr);
        System.out.println("USA week of month is " + weekOfMonthUs);
        System.out.println("UK week of month is " + weekOfMonthUk);

会给你

France week of month is 4
USA week of month is 5
UK week of month is 4
