        android:id="@+id/agenda_calendar_view"
        android:layout_width="match_parent"
        android:layout_height="match_parent"

        agendaCalendar:cellNowadaysDayColor="@color/white"
        tools:layout_editor_absoluteY="8dp"
        tools:layout_editor_absoluteX="8dp" />

Implement your activity/fragment from CalendarController

    fun getEmptyEventLayout(): Int

    fun getEventLayout() : Int

    fun onDaySelected(dayItem: IDayItem)

    fun onScrollToDate(calendar: Calendar)

Create your Model class:

    class SampleEvent(name: String, description: String) {
        var id: Long = 0
        var name: String = name
        var desciption: String = description
    }

Create model wrapper class for calendar widget:

    class MyCalendarEvent: BaseCalendarEvent {

    override lateinit var startTime: Calendar
    override lateinit var endTime: Calendar
    override var event: Any? = null

    override lateinit var instanceDay: Calendar


    override lateinit var dayReference: IDayItem

    override lateinit var weekReference: IWeekItem

    override fun setEventInstanceDay(instanceDay: Calendar): MyCalendarEvent {
        this.instanceDay = instanceDay
        this.instanceDay.set(Calendar.HOUR, 0)
        this.instanceDay.set(Calendar.MINUTE, 0)
        this.instanceDay.set(Calendar.SECOND, 0)
        this.instanceDay.set(Calendar.MILLISECOND, 0)
        this.instanceDay.set(Calendar.AM_PM, 0)
        return this
    }

    constructor(calendarEvent: CalendarEvent) {
    }


    constructor(startTime: Calendar,
                endTime: Calendar,
                dayItem: DayItem,
                event: SampleEvent?)  {
        this.startTime = startTime
        this.endTime = endTime
        this.dayReference = dayItem
        this.event = event
    }


    override
    fun copy(): MyCalendarEvent {
        return MyCalendarEvent(this)
    }

    override fun hasEvent(): Boolean {
        return event != null
    }

    override
    fun toString(): String {
        return super.toString()
     }
    }

Create adapter:

    class SampleEventAgendaAdapter(var context: Context) : DefaultEventAdapter() {
        private var format: SimpleDateFormat? = null

    init {
        format = SimpleDateFormat(context.getString(com.ognev.kotlin.agendacalendarview.R.string.header_date),
                Locale.ENGLISH)
    }

    override fun getHeaderLayout(): Int {
        return R.layout.view_agenda_header
    }

    override fun getHeaderItemView(view: View, day: Calendar) {
        val txtDayOfMonth = view.findViewById(R.id.view_agenda_day_of_month) as TextView
        val today = CalendarManager.instance!!.today

        if (DateHelper.sameDate(day, today)) {
            txtDayOfMonth.setTextColor(context.resources.getColor(R.color.main_blue))
        } else{
            txtDayOfMonth.setTextColor(context.resources.getColor(R.color.text_light_color))
        }

        txtDayOfMonth.text = format!!.format(day.time)
    }

    override fun getEventItemView(view: View, event: CalendarEvent, position: Int) {
        val myEvent = event as MyCalendarEvent
        val myObject: SampleEvent? = myEvent.event as SampleEvent?

        if(myEvent.hasEvent()) {
            (view.findViewById(R.id.name)
                    as TextView).text = myObject!!.name

            (view.findViewById(R.id.description)
                    as TextView).text = myObject.desciption
        }

        view.setOnClickListener {
            Toast.makeText(view.context, "Item: ".plus(position), Toast.LENGTH_SHORT).show()
        }
    }

    override fun getEventLayout(hasEvent: Boolean): Int {
        return if(hasEvent) R.layout.view_agenda_event else R.layout.view_agenda_empty_event
     }
    }

Configure calendar in your code with a CalendarContentManager:

        minDate = Calendar.getInstance()
        maxDate = Calendar.getInstance()
        minDate.add(Calendar.MONTH, -10)
        minDate.add(Calendar.YEAR, -1)
        minDate.set(Calendar.DAY_OF_MONTH, 1)
        maxDate.add(Calendar.YEAR, 1)

        eventList = ArrayList()

        contentManager = CalendarContentManager(this, agenda_calendar_view, SampleEventAgendaAdapter(applicationContext))

        contentManager.locale = Locale.ENGLISH
        contentManager.setDateRange(minDate, maxDate)

Add events to calendar from start

        contentManager.loadItemsFromStart(eventList!!)

Add events to calendar to End of list

        contentManager.loadFromEndCalendar(eventList!!)
