dependencies {
    compile 'jp.co.recruit_mp:LightCalendarView:1.0.1'
}

2) Add LightCalendarView into your layouts or view hierarchy.

<layout xmlns:android="http://schemas.android.com/apk/res/android">
    ...
        <jp.co.recruit_mp.android.lightcalendarview.LightCalendarView
            android:id="@+id/calendarView"
            android:layout_width="match_parent"
            android:layout_height="wrap_content" />
    ...
</layout>

Customization

Options

Lightweight Calendar View can be easily customized by setting properties in the layout XML file.

    <jp.co.recruit_mp.android.lightcalendarview.LightCalendarView
        android:id="@+id/calendarView"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:lcv_weekDayTextSize="18sp"
        app:lcv_dayTextSize="18sp"
        app:lcv_textColor="@color/calendar_day_text"
        app:lcv_selectionColor="@color/calendar_selection"
        app:lcv_accentColor="@color/calendar_accent"/>

The following properties are available:

property nametypedescription
app:lcv_weekDayTextSizedimensionThe text size of weekdays
app:lcv_dayTextSizedimensionThe text size of days
app:lcv_textColorcolor or resourceThe text color of weekdays and days
app:lcv_selectionColorcolor or resourceThe background color of selections
app:lcv_accentColorcolor or resourceThe color of accents
app:lcv_firstDayOfWeekintegerThe first day of the week (0 = Sunday, 1 = Monday, ..., 6 = Friday)

The customizations of text colors of selected days or today are done by setting <selector /> color resources to app:lcv_textColor, app:lcv_selectionColor, or app:lcv_accentColor with the following resource files for example.

NOTE that in all of the color resources, android:state_* are used to distinguish the state of each day view as follows:

statedescription
android:state_activeindicates whether the day view is for today (true) or other days (false)
android:state_selectedindicates whether the day view is selected (true) or not (false)

/res/color/calendar_day_text.xml

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <!-- the color of today when selected -->
    <item android:color="#ffd2d2" android:state_active="true" android:state_selected="true" />

    <!-- the color of today -->
    <item android:color="#c417ce" android:state_active="true" />

    <!-- the color of the selected day -->
    <item android:color="#ffffff" android:state_selected="true" />

    <!-- the color of other days -->
    <item android:color="#7c7c7c" />
</selector>

/res/color/calendar_selection.xml

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <!-- the background color of today when selected -->
    <item android:color="#3944ba" android:state_active="true" android:state_selected="true" />

    <!-- the background color of the other days when selected -->
    <item android:color="#565656" android:state_selected="true" />
</selector>

/res/color/calendar_accent.xml

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <!-- the color of accents in today when selected -->
    <item android:color="#ffd2d2" android:state_active="true" android:state_selected="true" />

    <!-- the color of accents in today -->
    <item android:color="#c417ce" android:state_active="true" />

    <!-- the color of accents in other days when selected -->
    <item android:color="#ffffff" android:state_selected="true" />

    <!-- the color of accents in other days -->
    <item android:color="#7c7c7c" />
</selector>

OnCalendarStateUpdatedListener

Add OnCalendarStateUpdatedListener to the calendar view to detect and handle the following events:

  • onSelectMonth(): the user swipes and changes the month
  • onSelectDay(): the user clicks one day in a month view

See the example implementation in MainActivity.kt of this listener on github.

Decorations

Use MonthView#setAccents(Date, Collection<Accent>) or MonthView#setAccents(Map<Date, Collection<Accent>>) to add decorations to each day.

Example:

calendarView.setOnStateUpdatedListener(object : LightCalendarView.OnStateUpdatedListener {
    override fun onMonthSelected(date: Date, view: MonthView) {
        val cal = Calendar.getInstance().apply { time = date }
        val monthEvents: Map<Date, List<Event>> = someApi.getMonthEvents(cal[Calendar.YEAR], cal[Calendar.MONTH])
        val monthAccents: Map<Date, List<Accent>> = monthEvents.mapValues { event -> DotAccent(radius = 10f, color = event.color, key = event) }
        view.setAccents(monthAccents)
    }
}

Coloring Day of The Week

Use LightCalendarView#setWeekDayFilterColor(weekDay: WeekDay, color: Int?) and LightCalendarView#setDayFilterColor(weekDay: WeekDay, color: Int?) to set the color scheme of day of the week in WeekDayView (e.g. Sunday, Monday, ...) and DayView (e.g. 1, 2, ...) respectively.

// coloring "sunday" (day of the week) in red
calendarView.setWeekDayFilterColor(WeekDay.SUNDAY, Color.RED)

// coloring sundays (days) in red
calendarView.setDayFilterColor(WeekDay.SUNDAY, Color.RED)

Note the library internally uses these color as ColorFilter, meaning it is overlayed on top of the text color set through LightCalendarView#setTextColor(color: Int).
