Adding Decorations Using Materialcalendarview Binding Library In Xamarin.android

I'm using the MaterialCalendarView library in my Xamarin.Android application, which works well for the most part except that I am unable add a span decoration to the calendar. Doc

Solution 1:

I am unable add a span decoration to the calendar.

The problem is that your ShouldDecorate always return false when you use dates.Contains(day) or dates.Exists(e => (e == day)).

It will compare HashCode firet so it will always return false, modify your code like below can solve this problem :

if (dates[0].ToString() == day.ToString() || dates[1].ToString() == day.ToString() || dates[2].ToString() == day.ToString() || dates[3].ToString() == day.ToString())
{
      returntrue;
}
else
{
       returnfalse;
}

Effect like this :
