Maven Central Travis branch

A Material design back port of Android's CalendarView. The goal is to have a Material look and feel, rather than 100% parity with the platform's implementation.

Demo Screen Capture


  1. Add compile 'com.prolificinteractive:material-calendarview:1.4.3' to your dependencies.
  2. Add MaterialCalendarView into your layouts or view hierarchy.
  3. Set a OnDateSelectedListener or call MaterialCalendarView.getSelectedDates() when you need it.

Javadoc Available Here




CalendarMode.WEEK and all week mode functionality is officially marked @Experimental. All APIs marked @Experimental are subject to change quickly and should not be used in production code. They are allowed for testing and feedback.

Major Change in 1.4.0

  • Breaking Change: setFirstDayOfWeek, setMin/MaxDate, and setCalendarDisplayMode are moved to a State object. This was necessary because it was unclear that these were not simple setters--individually, they were side effecting and triggered full adapter/date range recalculations. Typical usage of the view involves setting all these invariants up front during onCreate and it was unknown to the user that setting all 4 of these would create a lot of waste. Not to mention certain things were side effecting--some would reset the current day or selected date. As a result, the same 4 methods called in a different order could result in a different state, which is bad.

    For most cases you will simply need to replace setting those invariants with:

      .setMinimumDate(CalendarDay.from(2016, 4, 3))
      .setMaximumDate(CalendarDay.from(2016, 5, 12))

    mcv.state().edit() will retain previously set values; mcv.newState() will create a new state using default values. Calling commit will trigger the rebuild of adapters and date ranges. It is recommended these state changes occur as the first modification to MCV (before configuring anything else like current date or selected date); we make no guarantee those modifications will be retained when the state is modified.

    See CUSTOMIZATION_BUILDER for usage details.

  • New: setSelectionMode(SELECTION_MODE_RANGE) was added to allow 2 dates to be selected and have the entire range of dates selected. Much thanks to papageorgiouk for his work on this feature.

See other changes in the CHANGELOG.

Major Change in 1.3.0

  • Breaking change: getTileSize is deprecated. Use getTileWidth or getTileHeight.
  • Added goToNext and goToPrevious API to programmatically trigger paging
  • Allow users to click on dates outside of current month with setAllowClickDaysOutsideCurrentMonth
  • Set tile width/height separately rather than single tile size with setTileWidth and setTileHeight
  • Attributes: mcv_tileWidth, mcv_tileHeight, mcv_calendarMode
  • TalkBack APIs: setContentDescriptionArrowPast, ArrowFuture, Calendar

One of the aims of this library is to be customizable. The many options include:

Events, Highlighting, Custom Selectors, and More!

All of this and more can be done via the decorator api. Please check out the decorator documentation.

Custom Selectors and Colors

If you provide custom drawables or colors, you'll want to make sure they respond to state. Check out the documentation for custom states.
