    Is there a way to add a custom image to the background of an individual cell?  I was able to do this in iOS fairly easily by setting a custom delegate and overriding ViewForCellOfKind.

    Hello Jeff,

    Thank you for contacting the Android team!

    We don't support custom picture backgrounds by design, but we have a bitmap element in the cells, which can be modified to fill the cell thus become the background. This would be an example code:
    protected void onCreate(Bundle savedInstanceState) {
        final RadCalendarView calendarView = new RadCalendarView(this);
        calendarView.setAdapter(new Adapter(calendarView));
        final Bitmap bitmap = BitmapFactory.decodeResource(getResources(), R.drawable.my_pic);
        calendarView.setCustomizationRule(new Procedure<CalendarCell>() {
            Calendar calendar = Calendar.getInstance();
            public void apply(CalendarCell argument) {
                if (argument.getCellType() == CalendarCellType.Date) {
                    if (calendar.get(Calendar.DATE) == 5) {
                    } else {
    class Adapter extends CalendarAdapter {
        public Adapter(RadCalendarView owner) {
        protected CalendarDayCell generateCalendarDayCell() {
            return new Cell(this.owner);
        class Cell extends CalendarDayCell {
            public Cell(RadCalendarView owner) {
                setBitmapPosition(CalendarElement.TOP | CalendarElement.LEFT);
            protected void onArrange() {
                if (getBitmap() != null) {
                    this.setBitmap(Bitmap.createBitmap(getBitmap(), 0, 0, getWidth(), getHeight()));
    Please let me know if this is what you meant and if it suits your needs.

    Thank you for your time and all best!
