。

注意：
我不是ummalqura日历的专家。但我会尽力解释。
我举一个例子来解释为什么会出现这个问题。


考虑到
年
=private fun showHijriDatePicker(
        editText: TextInputEditText,
        isFromDatePicker: Boolean = false
    ) {
        val datePicker = HijriDatePickerDialog.newInstance(
            { _, year, monthOfYear, dayOfMonth ->
                when (isFromDatePicker) {
                    true -> {
                        fromDateValue = formatHijriDate(year, monthOfYear, dayOfMonth)
                    }
                    false -> {
                        toDateValue = formatHijriDate(year, monthOfYear, dayOfMonth)
                    }
                }
                editText.setText(formatHijriDate(year, monthOfYear, dayOfMonth))
            },
            ummalquraCalendar.get(UmmalquraCalendar.YEAR),
            ummalquraCalendar.get(UmmalquraCalendar.MONTH),
            ummalquraCalendar.get(UmmalquraCalendar.DAY_OF_MONTH)
        )
}
，
月
=1600
那么，这个月就只有
Jumada al-Akhirah(جمادى الآخرة)
天了。但是如果你尝试使用日期
29
，那么你会得到异常：
30


具有正确数据的工作代码示例：


Exception in thread "main" com.github.msarhan.ummalqura.calendar.DateTimeException: Invalid Hijrah day of month: 30
    at com.github.msarhan.ummalqura.calendar.HijrahChronology.getEpochDay(HijrahChronology.java:255)
    at com.github.msarhan.ummalqura.calendar.HijrahChronology.toGregorian(HijrahChronology.java:697)
    at com.github.msarhan.ummalqura.calendar.UmmalquraCalendar.set(UmmalquraCalendar.java:259)
    at java.base/java.util.Calendar.set(Calendar.java:1932)
    at com.example.demo.Example.main(Example.java:39)



输出：


public static void main(String[] args) throws ParseException {
   UmmalquraCalendar calendar = new UmmalquraCalendar();
   calendar.set(1600, Calendar.JUNE, 30);
   String displayArabic = calendar.getDisplayName(Calendar.MONTH, Calendar.LONG, new Locale("ar"))
            + " " + calendar.get(Calendar.DAY_OF_MONTH) + ", " + calendar.get(Calendar.MONTH);
   String displayEnglish = calendar.getDisplayName(Calendar.MONTH, Calendar.LONG, Locale.ENGLISH)
            + " " + calendar.get(Calendar.DAY_OF_MONTH) + ", " + calendar.get(Calendar.MONTH);
   System.out.println(displayArabic);
   System.out.println(displayEnglish);
}



注意：
 如果您不知道日历日期和年份，jar 中有一个名为 hijrah-config.properties 的文件，用于查找正确的月、年和日。此属性定义了 Hijrah 日历变体。
属性文件的样子：


جمادى الآخرة 29, 5
Jumada al-Akhirah 29, 5



希望这有帮助。
