android - Calendar.WEEK_OF_MONTH 在两种不同的设备上给出不同的结果

Question

我有两台设备 HTC Android 2.3.5 和三星 2.3.6现在我面临的问题是我需要日期在一个月中的星期几。

所以我编写了这段代码并安装在两部手机上。并将系统日期设置为

27th Jan 2013

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

现在在 HTC 上输出是

 weekOfMonth = 5

在三星上运行相同的代码会产生

 weekOfMonth = 4

这真的是在搞砸我的逻辑 n 提前计算。

我做错了什么吗？

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);

给你

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