Question:

for swipe smoothly, How to Preload data in MonthDayBinder for previous and next month?

When i swipe the month then it lags some milliseconds. so what to do for preload views for some months?

  exFiveCalendar.dayBinder = object : MonthDayBinder<DayViewContainer> {
                override fun create(view: View) = DayViewContainer(view)

                override fun bind(container: DayViewContainer, data: CalendarDay) {
                    container.binding.tvDate.text = data.date.dayOfMonth.toString()
                    // Some code for event previews
                }
            }

This is a bit tricky but you'll need to override the internal layout manager and override calculateExtraLayoutSpace.

See documentation

how to add calculateExtraLayoutSpace for this?

<com.kizitonwose.calendar.view.CalendarView
        android:id="@+id/exFiveCalendar"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:cv_daySize="rectangle"
        android:background="@color/month_divider"
        app:cv_dayViewResource="@layout/item_month_day"
        app:cv_outDateStyle="endOfGrid" />

There's no way to do this via xml presently.

This is now possible in the latest snapshot:

calendarView.layoutHelper = object : LayoutHelper() {
    override val calculateExtraLayoutSpace = { _: RecyclerView.State, extraLayoutSpace: IntArray ->
        extraLayoutSpace[0] = calendarView.width // desired extra start space
        extraLayoutSpace[1] = calendarView.width // desired extra end space
    }
}
