Hello Rincy,
Thank you for contacting the Android team.
I made a simple implementation of the screenshot you provided. Here is the code to get you started:
private RadCalendarView calendarView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.calendarView = new RadCalendarView(this);
this.calendarView.setAdapter(new CustomCalendarAdapter(this.calendarView));
this.calendarView.getEventAdapter().setRenderer(new CustomEventRenderer(this));
List<Event> events = new ArrayList<>();
events.add(new Event("Event", Calendar.getInstance().getTimeInMillis(), Calendar.getInstance().getTimeInMillis() + 1));
this.calendarView.getEventAdapter().setEvents(events);
this.calendarView.getAdapter().setStyle(CalendarStyles.light(this));
setContentView(this.calendarView);
}
private static class CustomCalendarAdapter extends CalendarAdapter {
public CustomCalendarAdapter(RadCalendarView owner) {
super(owner);
}
@Override
protected CalendarDayCell generateCalendarDayCell() {
return new CustomCalendarDayCell(this.owner);
}
}
private static class CustomCalendarDayCell extends CalendarDayCell {
public CustomCalendarDayCell(RadCalendarView owner) {
super(owner);
}
@Override
protected void drawEvents(Canvas canvas) {
if (this.getEvents() != null && this.getEvents().size() > 0)
this.owner.getEventAdapter().getRenderer().renderEvents(canvas, this);
}
}
private static class CustomEventRenderer extends EventRenderer {
private static final int COLOR_IDLE = Color.parseColor("#38b4db");
private static final int COLOR_SELECTED = Color.parseColor("#ffffff");
private float size;
private Paint paint;
public CustomEventRenderer(Context context) {
super(context);
this.size = Util.getDimen(TypedValue.COMPLEX_UNIT_DIP, 20);
this.paint = new Paint(Paint.ANTI_ALIAS_FLAG);
}
@Override
public void renderEvents(Canvas canvas, CalendarDayCell cell) {
Path path = new Path();
path.moveTo(cell.getRight() - this.size, cell.getBottom());
path.lineTo(cell.getRight(), cell.getBottom());
path.lineTo(cell.getRight(), cell.getBottom() - this.size);
path.close();
if (cell.isSelected())
this.paint.setColor(COLOR_SELECTED);
else
this.paint.setColor(COLOR_IDLE);
canvas.drawPath(path, this.paint);
}
}
This should be close to the desired result. Please let me know if you need some further assistance.
Thank you for your time and all best!
