Anzeigen bestimmter Ereignisse in bestimmten Monaten?

Question

Ich benutze CalenderView, um das Datum anzuzeigen und unter CalenderView Ich habe ListView verwendet, um das Datum (Tag) mit Ereignissen anzuzeigen. Ich bin in der Lage, alle Ereignisse mit Tag zu analysieren, aber was ich will ist, dass bestimmten Tag und Ereignisse anzeigen Spezifischer Monat. Wie kann dies erreicht werden?

Wie die Ereignisse auf der Listenansicht auf den basais des Kalendermonats von bestimmten Monat angezeigt werden?

Answer 1

Sie können diese Bibliothek verwenden, um Ereignisse im Kalender anzuzeigen. Die Dots werden unter den Daten angezeigt. MaterialCalendarView
Suchen Sie nach Decorator Sie können wth Daten in dieser Bibliothek verwenden.

materialCalendarView.setDateTextAppearance() 
materialCalendarView.addDecorator(new OpenSansDecorator(getActivity())); 
     materialCalendarView.setHeaderTextAppearance(R.style.TextAppearance_ProfileCalenderHeader); 

Dies kann verwendet werden Punkte in den Kalender anzuzeigen und u eine logische recylerview implementieren können in Kalender basierend auf Datum klicken zu zeigen.
