Changing color of single day in calendarview, android

Question

I've got the calendarview in eclipse and now I'm trying to change the appearance of a single day to highlight dates. I didn't find any useful method here, only changes of appearances of whole weekdates or monthdates. So is there a possibility to highlight a single day?

Also i know there are like 3 posts with the same issue, but none of them got answered.

If I interpret this right, he changes the appearance of all dates too, so this wouldn't be a solution to me, if I understood it wrong please correct me. — Werdli, Apr 08 '13 at 08:38

You could extend the native CalenderView to create your own CustomCalendarView and make any desired changes in appearance.

You can find the code for the native CalendarView here.

Thanks, didn't know the native CalendarView. Still android should maybe implement a method for changing single day colors in CalendarView! – Werdli Apr 08 '13 at 09:14
I find the calendar view very confusing to use. I don't understand why the user wants to scroll vertically or horizontally as if you are reading a foot-long text document. I find this not ergonomic at all. I am looking for ways on how to prevent calendar from being scrolled and to show only one month per view. – Neon Warge Apr 09 '15 at 14:16

The CalendarView source link is dead. – Colin Basnett Aug 20 '15 at 22:57

You may do it by obtain the child views of the CalendarView and change there configuations:

    final CalendarView calendar = new CalendarView(this);       
    java.lang.reflect.Field field = null;

    Class<?> cvClass = calendar.getClass();
    try {
        field = cvClass.getDeclaredField("mDayNamesHeader");    
        field.setAccessible(true);
    } catch (NoSuchFieldException e) {
    }

    ViewGroup tv = null;
    try {
        tv = (ViewGroup) field.get(calendar);
    } catch (IllegalAccessException e) {} 
      catch (IllegalArgumentException ){}

    TextView k =  (TextView) tv.getChildAt(1);
    k.setTextColor(Color.RED);

Here You can find all declarations:
