Firstly, PrimeDatePicker is a tool that provides picking a single day, multiple days, and a range of days. Secondly, you can use internal elements like MonthView and CalendarView as stand-alone views in your projects.
| Multiple Days | Civil BottomSheet | Dark |
Range of Days | Persian BottomSheet | Light |
Single Day | Hijri Dialog | Light |
Goto Feature | Japanese Dialog | Dark |

PrimeDatePicker is available on MavenCentral to download using build tools systems. Add the following lines to your build.gradle file:
dependencies {
implementation 'com.aminography:primedatepicker:3.6.0'
implementation 'com.aminography:primecalendar:1.7.0'
}To enjoy PrimeDatePicker, create an instance using a builder pattern in simple 4 steps.
- Decide on BottomSheet or Dialog representation along with an initial calendar:
// To show a date picker with Civil dates, also today as the starting date
val today = CivilCalendar()
val datePicker = PrimeDatePicker.bottomSheetWith(today) // or dialogWith(today)- Decide on picking strategy along with passing a proper callback:
val callback = SingleDayPickCallback { day ->
// TODO
}
val today = CivilCalendar()
val datePicker = PrimeDatePicker.bottomSheetWith(today)
.pickSingleDay(callback) // or pickRangeDays(callback) or pickMultipleDays(callback)- Apply some optional configurations:
...
val datePicker = PrimeDatePicker.bottomSheetWith(today)
.pickSingleDay(callback)
.initiallyPickedSingleDay(pickedDay)
...- Build the date picker and show it:
val callback = SingleDayPickCallback { day ->
// TODO
}
val today = CivilCalendar()
val datePicker = PrimeDatePicker.bottomSheetWith(today)
.pickSingleDay(callback)
.initiallyPickedSingleDay(pickedDay)
.build()
datePicker.show(supportFragmentManager, "SOME_TAG")Java
SingleDayPickCallback callback = new SingleDayPickCallback() {
@Override
public void onSingleDayPicked(PrimeCalendar singleDay) {
// TODO
}
};
// To show a date picker with Japanese dates, also today as the starting date
PrimeCalendar today = new JapaneseCalendar();
PrimeDatePicker datePicker = PrimeDatePicker.Companion.dialogWith(today)
.pickSingleDay(callback)
.build();
datePicker.show(getSupportFragmentManager(), "SOME_TAG");There are several builder functions applying relevant configurations on the date picker.
| Function | Picking Strategy |
| • minPossibleDate(minDate: PrimeCalendar) | ALL |
| Specifies the minimum feasible date to be shown in date picker, which is selectable. | |
| • maxPossibleDate(maxDate: PrimeCalendar) | ALL |
| Specifies the maximum feasible date to be shown in date picker, which is selectable. | |
| • firstDayOfWeek(firstDayOfWeek: Int) | ALL |
| Specifies the day that should be considered as the start of the week. Possible values are: Calendar.SUNDAY, Calendar.MONDAY, etc. | |
| • disabledDays(disabledDays: List<PrimeCalendar>) | ALL |
| Specifies the list of disabled days, which aren't selectable. | |
| • applyTheme(themeFactory: ThemeFactory) | ALL |
| Specifies the theme. | |
| • initiallyPickedSingleDay(pickedDay: PrimeCalendar) | SingleDay |
| Specifies initially picked day when the date picker has just shown. | |
| • initiallyPickedRangeDays(startDay: PrimeCalendar, endDay: PrimeCalendar) | RangeDays |
| Specifies initially picked range of days when the date picker has just shown. | |
| • autoSelectPickEndDay(autoSelect: Boolean) | RangeDays |
| Specifies automatic selection of picking end day when the start day gets picked. | |
| • initiallyPickedMultipleDays(pickedDays: List<PrimeCalendar>) | MultipleDays |
| Specifies initially picked multiple days when the date picker has just shown. | |
In addition to the builder functions, PrimeDatePicker receives some configurations from the input calendar. For example:
// shows a Persian calendar, but in English language, which leads to LTR direction
val calendar = PersianCalendar(Locale.ENGLISH).also {
it.year = 1398 // determines starting year
it.month = 7 // determines starting month
it.firstDayOfWeek = Calendar.MONDAY // sets first day of week to Monday
}
val datePicker = PrimeDatePicker.bottomSheetWith(calendar)
...
.build()PrimeDatePicker is fully customizable and you can tailor it to what you desire.
Almost everything you see is customizable. For example:
- text sizes & colors
- background & element colors
- padding & distances
- font typeface
- string formatter
- calendar animations & transition parameters
- etc
In this way, a set of customizable theme factory classes are provided to specify theme parameters. By default, there are two concrete subclasses for the them factory:
You can override their parameters, or inherit a class from, or make your own theme factory.
Here is an example of how to override theme parameters to customize it:
val themeFactory = object : LightThemeFactory() {
override val typefacePath: String?
get() = "fonts/Righteous-Regular.ttf"
override val dialogBackgroundColor: Int
get() = getColor(R.color.yellow100)
override val calendarViewBackgroundColor: Int
get() = getColor(R.color.yellow100)
override val pickedDayBackgroundShapeType: BackgroundShapeType
get() = BackgroundShapeType.ROUND_SQUARE
override val calendarViewPickedDayBackgroundColor: Int
get() = getColor(R.color.green800)
override val calendarViewPickedDayInRangeBackgroundColor: Int
get() = getColor(R.color.green400)
override val calendarViewPickedDayInRangeLabelTextColor: Int
get() = getColor(R.color.gray900)
override val calendarViewTodayLabelTextColor: Int
get() = getColor(R.color.purple200)
override val calendarViewWeekLabelFormatter: LabelFormatter
get() = { primeCalendar ->
when (primeCalendar[Calendar.DAY_OF_WEEK]) {
Calendar.SATURDAY,
Calendar.SUNDAY -> String.format("%s😍", primeCalendar.weekDayNameShort)
else -> String.format("%s", primeCalendar.weekDayNameShort)
}
}
override val calendarViewWeekLabelTextColors: SparseIntArray
get() = SparseIntArray(7).apply {
val red = getColor(R.color.red300)
val indigo = getColor(R.color.indigo500)
put(Calendar.SATURDAY, red)
put(Calendar.SUNDAY, red)
put(Calendar.MONDAY, indigo)
put(Calendar.TUESDAY, indigo)
put(Calendar.WEDNESDAY, indigo)
put(Calendar.THURSDAY, indigo)
put(Calendar.FRIDAY, indigo)
}
override val calendarViewShowAdjacentMonthDays: Boolean
get() = true
override val selectionBarBackgroundColor: Int
get() = getColor(R.color.brown600)
override val selectionBarRangeDaysItemBackgroundColor: Int
get() = getColor(R.color.orange700)
}Using above theme, we can transform the light theme (left picture) to the right one.

Java Theme Customization Example
BaseThemeFactory themeFactory = new LightThemeFactory() {
@NotNull
@Override
public PrimeCalendarView.FlingOrientation getCalendarViewFlingOrientation() {
return PrimeCalendarView.FlingOrientation.HORIZONTAL;
}
@Override
public int getSelectionBarBackgroundColor() {
return super.getColor(R.color.green300);
}
// Other customizations...
};If you want to change some texts in PrimeDatePicker, such as a button text, the current solution is to
define some strings in your project's strings.xml with equal name defined in the library's strings.xml, to override them.
