Shamsi/Jalali date picker with material design (Google Material Components Date Picker)

This library is based on Googles Material Date Picker. I reimplemented everything in Kotlin.

Minimum SDK: 21

Add this to your gradle file

    implementation 'com.xdev.arch.persiancalendar.datepicker:datepicker:0.3.2'

The picker can be customized via the MaterialDatePicker.Builder and the CalendarConstraints.Builder. These classes allow you to

• Select the mode: single date or range of dates.
• Select the bounds: bounds can be restricted to any contiguous set of months. Defaults Farvardin, 1388. to Esfand, 1409.
• Select valid days: valid days can restrict selections to weekdays only. Defaults to all days as valid.
• Set a title.
• Set the month to which the picker opens (defaults to the current month if within the bounds otherwise the earliest month within the bounds).
• Set a default selection (defaults to no selection).

First you can define a CalendarConstraints to limit dates You can use PersianCalendar class to set a Persian/Shamsi date or a java.util.Calendar instance

        val calendar = PersianCalendar()
        calendar.setPersian(1340, Month.FARVARDIN, 1)

        val start = calendar.timeInMillis
        
        calendar.setPersian(1409, Month.ESFAND, 29)
        val end = calendar.timeInMillis
        
        val openAt = PersianCalendar.getToday().timeInMillis
        
        val constraints = CalendarConstraints.Builder()
            .setStart(start)
            .setEnd(end)
            .setOpenAt(openAt)
            .setValidator(DateValidatorPointForward.from(start)).build()

Then we should create MaterialDatePicker

        val datePicker = MaterialDatePicker.Builder
            .datePicker()
            .setTitleText("تاریخ را انتخاب کنید.")
            .setCalendarConstraints(constraints).build()

        val rangePicker = MaterialDatePicker.Builder
            .dateRangePicker()
            .setTitleText("محدوده را انتخاب کنید.")
            .setCalendarConstraints(constraints).build()

And finaly call show()

            datepicker.show(supportFragmentManager, "aTag")
            rangePicker.show(supportFragmentManager, "aTag")

There are 4 listeners:

• OnPositiveButtonClickListener
• OnNegetiveButtonClickListener
• OnCancelListener
• OnDismissListener
