Download

PrimeDatePicker
is available on bintray to download using build tools systems. Add the following lines to your

build.gradle
file:
repositories {
    jcenter()
}

dependencies { implementation 'com.aminography:primedatepicker:3.3.2' implementation 'com.aminography:primecalendar:1.3.2' }


Usage

To enjoy

PrimeDatePicker
, create an instance using a builder pattern in simple 4 steps.
  1. Decide on BottomSheet or Dialog representation along with an initial calendar: ```kotlin // 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) ```

  1. Decide on picking strategy along with passing a proper callback: ```kotlin val callback = SingleDayPickCallback { day -> // TODO }

val today = CivilCalendar()

val datePicker = PrimeDatePicker.bottomSheetWith(today) .pickSingleDay(callback) // or pickRangeDays(callback) or pickMultipleDays(callback) ```

  1. Apply some optional configurations:
...

val datePicker = PrimeDatePicker.bottomSheetWith(today) .pickSingleDay(callback) .initiallyPickedSingleDay(pickedDay) ...

  1. Build the date picker and show it: ```kotlin val callback = SingleDayPickCallback { day -> // TODO }

val today = CivilCalendar()

val datePicker = PrimeDatePicker.bottomSheetWith(today) .pickSingleDay(callback) .initiallyPickedSingleDay(pickedDay) .build()

datePicker.show(supportFragmentManager, "SOME_TAG") ```


Java Example

Java ```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"); ```


Builder Configurations

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.
• initiallyPickedStartDay(startDay: PrimeCalendar, pickEndDay: Boolean) RangeDays
Specifies initially picked start day when the date picker has just shown.
• initiallyPickedMultipleDays(pickedDays: List<PrimeCalendar>) MultipleDays
Specifies initially picked multiple days when the date picker has just shown.


Input Calendar Configurations

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()


Customizing Theme

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 -&gt;
        when (primeCalendar[Calendar.DAY_OF_WEEK]) {
            Calendar.SATURDAY,
            Calendar.SUNDAY -&gt; String.format("%s😍", primeCalendar.weekDayNameShort)
            else -&gt; 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.


Normal Light Theme Customized Light Theme


Java Theme Customization Example ```java 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...

}; ```


Customizing Texts

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.


Stand-Alone Views

To see how to use

PrimeMonthView
&
PrimeCalendarView
, refer to wiki page .
