Ich habe einen benutzerdefinierten Kalender, der von dem gesehenen geändert wurde here. Beim erstmaligen Laden zeigt es alles so wie es sein soll.Benutzerdefinierter Kalender und Kalenderadapter
Allerdings habe ich zwei Probleme.
1.) Auf der Schaltfläche für den vorherigen Monat geht es wie erwartet von August bis Juli, aber es löscht nicht alle Bilder.
2.) Von Juli bis August bleibt es im Juli und verschiebt die Daten neu.

Sie haben eine Menge Code geschrieben ... gibt es trotzdem können Sie es auf die Teile eingrenzen, die relevant sind ... – btse
Da ich nicht weiß, wo der Fehler liegt, ist es schwer, das zu tun ... die XML's gibt es nur zu Informationszwecken, so dass die beiden Klassen ein Schwerpunkt sein sollten. – jcaruso
