使用代码

 override fun lazyInit() {
    viewBinding.flStartDay.click { viewBinding.calendarView.pickType = PickType.RANGE_START }
    viewBinding.flEndDay.click { viewBinding.calendarView.pickType = PickType.RANGE_END }
    val calendarView = viewBinding.calendarView
    calendarView.typeface = ResourcesCompat.getFont(mContext, R.font.roboto_medium)
    calendarView.calendarType = CalendarType.CIVIL
    calendarView.pickType = PickType.SINGLE
    calendarView.flingOrientation = PrimeCalendarView.FlingOrientation.HORIZONTAL
    calendarView.locale = Locale.getDefault()
    calendarView.animateSelection = false
    calendarView.pickedDayLabelTextColor = Color.WHITE
    calendarView.firstDayOfWeek = Calendar.SUNDAY
    calendarView.todayLabelTextColor = Color.parseColor("#c62430")
    calendarView.dayLabelTextColor = Color.parseColor("#333333")
    calendarView.disabledDayLabelTextColor = Color.parseColor("#C5C5C5")
    calendarView.pickedDayBackgroundColor = Color.parseColor("#c62430")
    calendarView.weekLabelTextColor = Color.parseColor("#333333")
    calendarView.monthLabelTextColor = Color.parseColor("#333333")
    calendarView.dividerColor = Color.TRANSPARENT
    calendarView.dividerInsetBottom = 0
    calendarView.dividerInsetTop = 0
    calendarView.dividerInsetLeft = 0
    calendarView.dividerInsetRight = 0
    calendarView.dayLabelTextSize = 14.dp2px()
    calendarView.weekLabelTextSize = 12.dp2px()
    calendarView.monthLabelTextSize = 12.dp2px()
    calendarView.minDateCalendar = CalendarFactory.newInstance(CalendarType.CIVIL).also { it[Calendar.MONTH] -= 12 }
    calendarView.maxDateCalendar = CalendarFactory.newInstance(CalendarType.CIVIL)
    calendarView.onDayPickedListener = OnDayPickedListener { _, _, startDay, endDay, _ ->
      if (startDay != null) viewBinding.tvStartDay.text = "${startDay.year}-${startDay.month + 1}-${startDay.dayOfMonth}"
      if (endDay != null) viewBinding.tvEndDay.text = "${endDay.year}-${endDay.month + 1}-${endDay.dayOfMonth}"
    }
}
