Mam bazę danych dat, w której mam więcej niż jedną datę, więc chcę podkreślić tło wszystkich dat, które dostałem z bazy danych i wypróbowałem logika, ale nie udało się tutaj umieścić mój kod idzie w nieskończoną pętlę.i chcesz uzyskać wynik podobny do tego przypuszczam, że mam daty takie jak w bazie danych 5/3/2013 i 9/3/2013, to dwa tła powinny być tłem wyróżnij w widoku kalendarza. Kiedyś ten link http://www.androidhub4you.com/2012/10/custom-calendar-in-android.html tutaj jest mój kod:Jak podświetlić daty kalendarza, które daty pochodzą z bazy danych
tutaj w printmonth() funkcja zrobiłem zmiany
