Customize FlexibleCalendar using the CalendarView interface

calendarView.setCalendarView(new FlexibleCalendarView.CalendarView() {
    @Override
    public BaseCellView getCellView(int position, View convertView, ViewGroup parent, int cellType) {
        //customize the date cells
        BaseCellView cellView = (BaseCellView) convertView;
        if (cellView == null) {
            LayoutInflater inflater = LayoutInflater.from(CalendarActivity4.this);
            cellView = (BaseCellView) inflater.inflate(R.layout.calendar3_date_cell_view, null);
        }
        if (cellType == BaseCellView.TODAY){
            cellView.setTextColor(getResources().getColor(android.R.color.holo_red_dark));
            cellView.setTextSize(15);
        } else {
            cellView.setTextColor(getResources().getColor(android.R.color.white));
            cellView.setTextSize(12);
        }
        return cellView;
    }
    @Override
    public BaseCellView getWeekdayCellView(int position, View convertView, ViewGroup parent) {
        //customize the weekday header cells
        BaseCellView cellView = (BaseCellView) convertView;
        if (cellView == null) {
            LayoutInflater inflater = LayoutInflater.from(CalendarActivity4.this);
            cellView = (BaseCellView) inflater.inflate(R.layout.calendar3_week_cell_view, null);
            cellView.setBackgroundColor(getResources().getColor(android.R.color.holo_purple));
            cellView.setTextColor(getResources().getColor(android.R.color.holo_orange_light));
            cellView.setTextSize(18);
        }
        return cellView;
    }
    @Override
    public String getDayOfWeekDisplayValue(int dayOfWeek, String defaultValue) {
        return String.valueOf(defaultValue.charAt(0));
    }
});

Display events for a day using the EventDataProvider

calendarView.setEventDataProvider(new FlexibleCalendarView.EventDataProvider() {
    @Override
    public List<? extends Event> getEventsForTheDay(int year, int month, int day) {
        return getEventColorList(year,month,day);
    }
});

Track the month change event by setting the OnMonthChangeListener

calendarView.setOnMonthChangeListener(new FlexibleCalendarView.OnMonthChangeListener() {
    @Override
    public void onMonthChange(int year, int month, int direction) {
        //do things on month change
    }
});

Customizations:

Display events in different styles.

Customize the cells and events by extending the class BaseCellView.

Existing cells include CircularEventCellView, SquareCellView and EventCountCellView.

Choose whether to show dates outside month or not by setting the showDatesOutsideMonth flag, using FlexibleCalendarView#showDatesOutsideMonth() method.

Set the first day of the week using FlexibleCalendarView#setStartDayOfTheWeek method or through xml by setting the attribute startDayOfTheWeek.

Disable auto date selection on month change by using FlexibleCalendarView#disableAutoDateSelection method or through xml by using disableAutoDateSelection.

Navigate the calendar:
