android-查找两个日期之间的月份和日期差异

我想找到两个日期之间月份和日期的日期差异.一个是我系统的当前日期,另一个是将来的日期.

未来日期采用以下格式：

2014-02-06 21:26

我使用下面的代码来找到区别.

1.

currentCal = Calendar.getInstance();weddingCal = Calendar.getInstance();weddingCal.clear();DateFormat formatterResponseDate = new SimpleDateFormat("yyyy-MM-dd HH:mm");formatterResponseDate.setTimeZone(TimeZone.getTimeZone("GMT")); weddingCal.setTime(formatterResponseDate.parse(responseThis.trim()));long dateDiff = weddingCal.getTimeInMillis() -currentCal.getTimeInMillis();long months = dateDiff / (30 * 24 * 60 * 60 * 1000); long days = (dateDiff % (30 * 24 * 60 * 60 * 1000)) / (24 * 60 * 60 * 1000);

但这给了我错误的结果,我认为这并不方便,因为有时一个月中有31天.我也曾使用JODA – Time来找到差异,但这也无济于事.

2.

currentCal = Calendar.getInstance();startDate = new DateTime(currentCal.get(Calendar.YEAR),(currentCal.get(Calendar.MONTH)+1),currentCal.get(Calendar.DAY_OF_MONTH), currentCal.get(Calendar.HOUR),currentCal.get(Calendar.MINUTE));weddingCal = Calendar.getInstance();weddingCal.clear();weddingCal.setTime(formatterResponseDate.parse(responseThis.trim()));endDate = new DateTime(weddingCal.get(Calendar.YEAR), (weddingCal.get(Calendar.MONTH)+1),weddingCal.get(Calendar.DAY_OF_MONTH), weddingCal.get(Calendar.HOUR),weddingCal.get(Calendar.MINUTE));Period period = new Period(startDate, endDate);tvMonth.setText(String.valueOf(period.getMonths()));tvDays.setText(String.valueOf(period.getDays()));

两者均无法正常工作,请帮助我,如何找到它？
谢谢

解决方法:

我用下面的代码,它工作正常.

currentCal = Calendar.getInstance();startDate = new DateTime(currentCal.get(Calendar.YEAR),                         (currentCal.get(Calendar.MONTH)+1),                         currentCal.get(Calendar.DAY_OF_MONTH),                         currentCal.get(Calendar.HOUR),                         currentCal.get(Calendar.MINUTE));weddingCal = Calendar.getInstance();weddingCal.clear();weddingCal.setTime(formatterResponseDate.parse(responseThis.trim()));endDate = new DateTime(weddingCal.get(Calendar.YEAR),                       (weddingCal.get(Calendar.MONTH)+1),                       weddingCal.get(Calendar.DAY_OF_MONTH),                       weddingCal.get(Calendar.HOUR),                       weddingCal.get(Calendar.MINUTE));Period period = new Period(startDate, endDate, PeriodType.yearMonthDayTime());tvMonth.setText(String.valueOf(period.getMonths()));tvDays.setText(String.valueOf(period.getDays()));
