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.

Recent Changes

Major Change in 2.0

Material CalendarView 2.0 comes in with a major change into the core of it's API, we transitioned from using

java.util.Calendar
to
java.time.LocalDate
. Also that should not impact the public api (we are still using
CalendarDay
), both
Calendar
and
LocalDate
function a little bit differently. One example of that: Months are now indexed from 1 (January) to 12 (December). You can access from the
LocalDate
from
CalendarDay
using
getDate()
.

Major Change in 1.6.0

Also this release doesn't have any break changes, it provides significant improvements to the widget. More customization have been added for the user (custom fonts, long click listener, show/hide weekdays) as well as various fixes, improvements to the sample app, and general cleanup. Make sure to check the CHANGELOG and the release section for more details.

Major Change in 1.5.0

We recently updated to the latest gradle and decided to move over our libraries to the hosting service Jitpack. Please refer to the installation section for more details.

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:

java
  mcv.state().edit()
    .setFirstDayOfWeek(Calendar.WEDNESDAY)
    .setMinimumDate(CalendarDay.from(2016, 4, 3))
    .setMaximumDate(CalendarDay.from(2016, 5, 12))
    .setCalendarDisplayMode(CalendarMode.WEEKS)
    .commit();

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.
