Using date pickers

Before you can use Material date pickers, you need to add a dependency to the Material Components for Android library. For more information, go to the Getting started page.

Date pickers let users select a date or range of dates. They should be suitable for the context in which they appear.

Date pickers can be embedded into dialogs on mobile devices.

Usage

The following image shows a date picker and a range date picker.

API and source code:

MaterialDatePicker
- Class definition
- Class source
CalendarConstraints
- Class definition
- Class source

A date picker can be instantiated with MaterialDatePicker.Builder.datePicker():

val datePicker =
    MaterialDatePicker.Builder.datePicker()
        .setTitleText("Select date")
        .build()

A date range picker can be instantiated with MaterialDatePicker.Builder.dateRangePicker():

val dateRangePicker =
    MaterialDatePicker.Builder.dateRangePicker()
        .setTitleText("Select dates")
        .build()

To set a default selection:

// Opens the date picker with today's date selected.
MaterialDatePicker.Builder().datePicker()
      ...
    .setSelection(MaterialDatePicker.todayInUtcMilliseconds())

// Opens the date range picker with the range of the first day of
// the month to today selected.
MaterialDatePicker.Builder.dateRangePicker()
      ...
    .setSelection(
          Pair(
            MaterialDatePicker.thisMonthInUtcMilliseconds(),
            MaterialDatePicker.todayInUtcMilliseconds()
          )
        )

The picker can be started in text input mode with:

MaterialDatePicker.Builder().datePicker()
      ...
    .setInputMode(MaterialDatePicker.INPUT_MODE_TEXT)

A DayViewDecorator can be set allowing customizing the day of month views within the picker (example of a DayViewDecorator):

MaterialDatePicker.Builder().datePicker()
      ...
    .setDayViewDecorator(new CircleIndicatorDecorator())

To show the picker to the user:

 picker.show(supportFragmentManager, "tag");

Subscribe to button clicks or dismiss events with the following calls:

picker.addOnPositiveButtonClickListener {
    // Respond to positive button click.
}
picker.addOnNegativeButtonClickListener {
    // Respond to negative button click.
}
picker.addOnCancelListener {
    // Respond to cancel button click.
}
picker.addOnDismissListener {
    // Respond to dismiss events.
}

Finally, you can get the user selection with datePicker.selection.

Adding calendar constraints

To constrain the calendar from the beginning to the end of this year:

val today = MaterialDatePicker.todayInUtcMilliseconds()
val calendar = Calendar.getInstance(TimeZone.getTimeZone("UTC"))

calendar.timeInMillis = today
calendar[Calendar.MONTH] = Calendar.JANUARY
val janThisYear = calendar.timeInMillis

calendar.timeInMillis = today
calendar[Calendar.MONTH] = Calendar.DECEMBER
val decThisYear = calendar.timeInMillis

// Build constraints.
val constraintsBuilder =
   CalendarConstraints.Builder()
       .setStart(janThisYear)
       .setEnd(decThisYear)

To open the picker at a default month:

...
calendar[Calendar.MONTH] = Calendar.FEBRUARY
val february = calendar.timeInMillis

val constraintsBuilder =
   CalendarConstraints.Builder()
       .setOpenAt(february)

To set a validator:

// Makes only dates from today forward selectable.
val constraintsBuilder =
   CalendarConstraints.Builder()
       .setValidator(DateValidatorPointForward.now)

// Makes only dates from February forward selectable.
val constraintsBuilder =
   CalendarConstraints.Builder()
       .setValidator(DateValidatorPointForward.from(february))

You can also use DateValidatorPointBackward or customize by creating a class that implements DateValidator (example of a DateValidatorWeekdays in the MDC catalog).

Set the constraint to the picker's builder:

MaterialDatePicker.Builder().datePicker()
      ...
    .setCalendarConstraints(constraintsBuilder.build())

Making date pickers accessible

Material date pickers are fully accessible and compatible with screen readers. The title of your date picker will be read when the user launches the dialog. Use a descriptive title for the task:

val picker =
   MaterialDatePicker.Builder()
      ...
       .setTitleText("Select appointment date")
   ...

Calendar date picker

Calendar date pickers can be used to select dates in the near future or past, when it’s useful to see them in a calendar month format. They are displayed in a dialog.

Common use cases include:

Making a restaurant reservation
Scheduling a meeting

Date picker example

The following example shows a date picker with a date selected.

In code:

val datePicker =
    MaterialDatePicker.Builder.datePicker()
        .setTitleText("Select date")
        .setSelection(MaterialDatePicker.todayInUtcMilliseconds())
        .build()

datePicker.show()

Date range pickers

Mobile date range pickers allow selection of a range of dates. They cover the entire screen.

Common use cases include:

Booking a flight
Reserving a hotel

Date range picker example

The following example shows a date range picker with a date range selected.

In code:

val dateRangePicker =
    MaterialDatePicker.Builder.dateRangePicker()
        .setTitleText("Select dates")
        .setSelection(
          Pair(
            MaterialDatePicker.thisMonthInUtcMilliseconds(),
            MaterialDatePicker.todayInUtcMilliseconds()
          )
        )
        .build()

dateRangePicker.show()

Theming date pickers

Date pickers support Material Theming which can customize color, shape and typography.

Date picker theming example

API and source code:

MaterialDatePicker
- Class definition
- Class source
CalendarConstraints
- Class definition
- Class source

The following example shows a date picker with Material Theming.

Use theme attributes and styles in res/values/styles.xml, which apply to all date pickers and affect other components:

<style name="Theme.App" parent="Theme.Material3.*">
    ...
    <item name="colorPrimary">@color/shrine_pink_100</item>
    <item name="colorOnPrimary">@color/shrine_pink_900</item>
    <item name="shapeAppearanceSmallComponent">@style/ShapeAppearance.App.SmallComponent</item>
    <item name="shapeAppearanceMediumComponent">@style/ShapeAppearance.App.MediumComponent</item>
</style>

<style name="ShapeAppearance.App.SmallComponent" parent="ShapeAppearance.Material3.SmallComponent">
    <item name="cornerFamily">cut</item>
</style>

<style name="ShapeAppearance.App.MediumComponent" parent="ShapeAppearance.Material3.MediumComponent">
    <item name="cornerSize">16dp</item>
</style>

Use a default style theme attribute, styles and a theme overlay which apply to all date pickers but do not affect other components:

<style name="Theme.App" parent="Theme.Material3.*">
    ...
    <item name="materialCalendarTheme">@style/ThemeOverlay.App.DatePicker</item>
</style>

<style name="ThemeOverlay.App.DatePicker" parent="@style/ThemeOverlay.Material3.MaterialCalendar">
    <item name="colorPrimary">@color/shrine_pink_100</item>
    <item name="colorOnPrimary">@color/shrine_pink_900</item>
    <item name="shapeAppearanceSmallComponent">@style/ShapeAppearance.App.SmallComponent</item>
    <item name="shapeAppearanceMediumComponent">@style/ShapeAppearance.App.MediumComponent</item>
    <!-- Customize text field of the text input mode. -->
    <item name="textInputStyle">@style/Widget.App.TextInputLayout</item>
  </style>

Set the theme in code, which affects only this date picker:

val picker =
   MaterialDatePicker.Builder()
      ...
       .setTheme(.style.ThemeOverlay_App_DatePicker)
