Android 周数对于手机而言错误，但模拟器则不然
我有一个程序，它在很大程度上依赖于识别一年中的周数。我已经完成了跑腿工作，找出了会导致的所有问题，并用这种方法解决了。我在 53 周之类的年份里工作得非常完美。我唯一的问题是，当我在 2.2 版模拟器上运行它时，它运行得很好，就像这是第 19 周，它是正确的。当我在手机 G1 上运行它时，周显示 20。我该如何解决这个问题？
这是我的周代码：
/**
* Format the date into a number that is the year*100 plus the week i.e. 2008 and its week 11
* would show as 811
* @param - String of a date to create a week id, must be in format of 2011-01-31 (YYYY-MM-DD)
* @return returns next weeks id
*/
public static int getWeekId(String date){
// Set the first day of week to Monday and set the starting new year weeks
// as a full first week in the new year.
Calendar c = Calendar.getInstance();
c.setFirstDayOfWeek(Calendar.MONDAY);
c.setMinimalDaysInFirstWeek(7);
if (!date.equalsIgnoreCase("")) {
String[] token = date.split("-", 3);
int year = Integer.parseInt(token[0]);
int month = Integer.parseInt(token[1])-1; // months are 0-11 stupid..
int day = Integer.parseInt(token[2]);
c.set(year, month, day);
}
int yearWeek = ( (c.get(Calendar.YEAR) - 2000)*100 + (c.get(Calendar.WEEK_OF_YEAR)));
Log.d("getWeekId()"," WEEK_OF_YEAR: " + c.get(Calendar.WEEK_OF_YEAR));
return yearWeek;
}
I have a program where it relies heavily on identifying the week number for the year. I have done the leg work and figured out all the problems that will cause and settle with this method. I works perfect for years that have 53 weeks and such. My only issue is that when I run it on my emulator for 2.2 it works perfect, like this is week 19 and its correct. when I run it on my phone a G1, the week shows 20. How do I fix this?
Here is my week code:
/**
* Format the date into a number that is the year*100 plus the week i.e. 2008 and its week 11
* would show as 811
* @param - String of a date to create a week id, must be in format of 2011-01-31 (YYYY-MM-DD)
* @return returns next weeks id
*/
public static int getWeekId(String date){
// Set the first day of week to Monday and set the starting new year weeks
// as a full first week in the new year.
Calendar c = Calendar.getInstance();
c.setFirstDayOfWeek(Calendar.MONDAY);
c.setMinimalDaysInFirstWeek(7);
if (!date.equalsIgnoreCase("")) {
String[] token = date.split("-", 3);
int year = Integer.parseInt(token[0]);
int month = Integer.parseInt(token[1])-1; // months are 0-11 stupid..
int day = Integer.parseInt(token[2]);
c.set(year, month, day);
}
int yearWeek = ( (c.get(Calendar.YEAR) - 2000)*100 + (c.get(Calendar.WEEK_OF_YEAR)));
Log.d("getWeekId()"," WEEK_OF_YEAR: " + c.get(Calendar.WEEK_OF_YEAR));
return yearWeek;
}

当使用 2011-01-01 调用时，代码当前返回 1152。这是预期的吗？
(I'd leave this in a comment, but my account does not yet have commenting permissions.)
When called with 2011-01-01, the code currently returns 1152. Is this as intended?
就其价值而言，它可能比您所写的更复杂。我这么说并不是刻薄的，只是可能有很多有趣的怪异案例你没有考虑过。有一个很好的 Java 库，它了解大量有关时间的内容，并且可能已经编写了此代码，请查看： http://joda-time.sourceforge.net/
For what it's worth, there is likely more intricacy to it than you've written. I don't say this to be mean, it's just that there are probably lots of interesting weird cases that you haven't considered. There is a good Java library that knows a ton of stuff about times, and may have this code written already, Check it out: http://joda-time.sourceforge.net/
显然这是 Android 手机中的一个错误...所以在使用 Android 1.6 时请注意这一点。
Apparently its a bug in the android phone...so watch out for this when using android 1.6.
