Unfortunately, I no longer have the time to continue developing this library and my focus has shifted. If you are switching to Flutter, you might be interested in my timetable package as a replacement.

This library provides a Material Design CalendarView for Android (week and day view; more coming soon!). The default style is copied from the Google Calendar app, but almost everything is customizable.

Features

Usage

  1. Add the library to your gradle script

    implementation 'com.jonaswanke.calendar:calendar:0.1.1'
  2. Add CalendarView in you layout

    <com.jonaswanke.calendar.CalendarView
      android:id="@+id/calendar"
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      app:range="week" />

    Currently supported ranges are week and day. More coming soon!

  3. Provide events to the view

    calendar.eventRequestCallback = { week ->
      // Retrieve events synchronously or asynchronously
      val events: List<Event> = // ...
      calendar.setEventsForWeek(week, events)
    }

    CalendarView currently caches two views for either side of the current view (e.g. two weeks to the left and two to the right) for smooth swiping. When a new view is loaded, eventRequestCallback will be called with the new week.
    You should then supply events starting in that week by calling calendar.setEventsForWeek() (multi-day and multi-week events are always stored where they begin and will then be distributed to where they are required).

    You can call calendar.setEventsForWeek() anytime you want. The events will be cached and used when required. Old events starting in that week are overridden.

    Events implement the following properties:

    val title: String // Displayed in bold
    val description: String? // Optional; shown in a second line
    @get:ColorInt
    val color: Int? // Optional background color
    val start: Long // Start time
    val end: Long // End time
    val allDay: Boolean // Whether the event takes all day. If so, start and end are just used to determine the day
  4. Add your listeners (optional)

    calendar.onEventClickListener = { event ->
      // Event was clicked
      Toast.makeText(this, "${event.title} clicked", Toast.LENGTH_LONG).show()
    }
    calendar.onEventLongClickListener = { event ->
      // Event was long clicked
      Toast.makeText(this, "${event.title} long clicked", Toast.LENGTH_LONG).show()
    }

    As shown in screenshot 3 (above), the user can add events by tapping empty space inside CalendarView. This only works when an onAddEventListener is set.

    calendar.onAddEventListener = { addEvent ->
      // User tried to create a new event. addEvent is an event with populated start and end.
      Toast.makeText(this, "Add event at ${start}", Toast.LENGTH_SHORT).show()
      // Return true to remove the placeholder
      true
    }

Sample

There is also a sample app to get you started.
