有趣的是，这个日历返回一周的第一天作为下一个星期日，这是完全不合逻辑的。
所以我做了索引转换函数来排序天。1月份的时候还行，但我一搬到2月份，不知怎么的，2月份的第一周就成了1月份的最后一周。
所以天现在很好，但是由于某种原因，周不正常了。甚至Calendar.DAY_OF_WEEK也为特定的Calendar.WEEK_OF_MONTH返回错误的数据。在这个原生Calendar中没有逻辑，我不能在一年中所有的日子里制作简单的迭代器来为我的自定义日历形成一些可用的结构。
代码:
private fun loadDatePickerYear(year: Int): DatePickerYear{
val cal = Calendar.getInstance(Locale.forLanguageTag("cs"))
cal.set(Calendar.YEAR, year)
val months = mutableListOf<DatePickerMonth>()
(0..11).forEach { month->
months.add(loadDatePickerMonth(cal, month))
}
return DatePickerYear(months, year)
}
private fun loadDatePickerMonth(cal: Calendar, month: Int): DatePickerMonth{
App.log("DatePickerNew: loadDatePickerMonth: $month")
cal.set(Calendar.MONTH, month)
val firstWeek = cal.getActualMinimum(Calendar.WEEK_OF_MONTH)
val lastWeek = cal.getActualMaximum(Calendar.WEEK_OF_MONTH)
val weeks = mutableListOf<DatePickerWeek>()
(firstWeek..lastWeek).forEach { week->
weeks.add(loadDatePickerWeek(cal, week))
}
return DatePickerMonth(weeks, month)
}
private fun loadDatePickerWeek(cal: Calendar, week: Int): DatePickerWeek{
App.log("DatePickerNew: loadDatePickerWeek: $week")
cal.set(Calendar.WEEK_OF_MONTH, week)
val firstDay = cal.getActualMinimum(Calendar.DAY_OF_WEEK)
val lastDay = cal.getActualMaximum(Calendar.DAY_OF_WEEK)
val days = mutableListOf<DatePickerDay>()
(firstDay..lastDay).forEach { day->
days.add(loadDatePickerDay(cal, day))
}
days.sortBy { it.dayOfWeek }
days.forEach {
App.log("DatePickerNew: loadDatePickerWeek: sorted: ${it.dayOfWeek}, ${it.dayAsDate}")
}
return DatePickerWeek(days, week)
}
private fun loadDatePickerDay(cal: Calendar, day: Int): DatePickerDay{
cal.set(Calendar.DAY_OF_WEEK, day)
val date = Date(cal.timeInMillis)
//return day
App.log("DatePickerNew: loadDatePickerDay: $day $date")
return DatePickerDay(date, getEuropeanDayIndex(day)!!)
}
//2, 3, 4, 5, 6, 7, 1
fun getEuropeanDayIndex(dayOfWeek: Int): Int?{
return when(dayOfWeek){
1 -> 7
2 -> 1
3 -> 2
4 -> 3
5 -> 4
6 -> 5
7 -> 6
else -> null
}
}

if you are making custom calendar then make the layout start from "Monday" and
get week start day as monday like:
Actually you have not shared your customcalender code so this is what i
get from current question
Calendar calendar = Calendar.getInstance();
calendar.add(Calendar.DAY_OF_MONTH, Calendar.MONDAY-
calendar.get(Calendar.DAY_OF_WEEK));
Log.w(TAG, "first day of week" + calendar.getTime());
要固定周数，您可以执行
cal.setFirstDayOfWeek(Calendar.MONDAY);
就在你创建它之后
