我正在尝试建立一个安卓应用程序的calenderView使用库https://github.com/alamkanak/Android-Week-View和这个库https://github.com/mangstadt/biweekly来解析ICS。然而，我在创建具有重复性的事件时遇到了问题，就像在示例中一样。

protected  TreeMap<Integer,TreeMap<Integer,List<WeekViewEvent>>>  doInBackground(String... params) {
        ICalendar ical = Biweekly.parse(params[0]).first();
        List<VEvent> le = ical.getEvents();
        for(VEvent ev: le){
            Calendar startTime = Calendar.getInstance();
            startTime.setTimeInMillis(ev.getDateStart().getValue().getTime());
            if(ev.getRecurrenceRule()!=null){
                //Don't know what do I do here

            }

            int year = startTime.get(Calendar.YEAR);
            int month = startTime.get(Calendar.MONTH);
            //Log.v("Calendar",year+" Ano " + month +" Mes");
            Calendar endTime = Calendar.getInstance();
            if(ev.getDateEnd()==null){
                continue;
            }
            endTime.setTimeInMillis(ev.getDateEnd().getValue().getTime());
            WeekViewEvent we = new WeekViewEvent(0,ev.getSummary().getValue(),startTime,endTime);
            if(eventos.get(we.getStartTime().get(Calendar.YEAR))==null){
                TreeMap<Integer,List<WeekViewEvent>> as = new TreeMap<>();
                List<WeekViewEvent> listEv = new ArrayList<>();
                listEv.add(we);
                as.put(we.getStartTime().get(Calendar.MONTH),listEv);
                eventos.put(we.getStartTime().get(Calendar.YEAR),as);
            }
            else {
                TreeMap<Integer, List <WeekViewEvent>> as = eventos.get(we.getStartTime().get(Calendar.YEAR));
                if(as.containsKey(we.getStartTime().get(Calendar.MONTH))){
                    as.get(we.getStartTime().get(Calendar.MONTH)).add(we);
                }else {
                    List<WeekViewEvent> listEv= new ArrayList<>();
                    listEv.add(we);
                    as.put(we.getStartTime().get(Calendar.MONTH),listEv);
                }
            }
        }
        return eventos;
    }

任何帮助都是非常感谢的。

也许你应该在http://jfxtras.org/上尝试一下iCalendarAgenda

它利用了一种新的Java，称为iCalendarFX。虽然我还没有在安卓上使用过它，但我知道Tom Eugelink已经得到了Agenda控件( iCalendarAgenda扩展)，可以在安卓上运行。

我写了iCalendarFx，它可以很容易地解析你那里的VEVENT。
