android - 日历与android中的自定义添加帐户同步

Question

我想在日历中添加事件，我可以添加帐户，但我不知道如何与日历同步。

我应该创建一个新的日历 ID 吗？如何验证事件是否已在日历上创建？

看看这个 Google code project 这将指导您。

在该项目中，有一种方法可以为您提供与 Calender 关联的帐户 ID。

private int ListSelectedCalendars() {
        int result = 0;
        String[] projection = new String[] { "_id", "name" };
        String selection = "selected=1";
        String path = "calendars";

        Cursor managedCursor = getCalendarManagedCursor(projection, selection,
                path);

        if (managedCursor != null && managedCursor.moveToFirst()) {

            Log.i(DEBUG_TAG, "Listing Selected Calendars Only");

            int nameColumn = managedCursor.getColumnIndex("name");
            int idColumn = managedCursor.getColumnIndex("_id");

            do {
                String calName = managedCursor.getString(nameColumn);
                String calId = managedCursor.getString(idColumn);
                Log.i(DEBUG_TAG, "Found Calendar '" + calName + "' (ID="
                        + calId + ")");
                // You have to give email id in below line, right now i puted my email id
                if (calName != null && calName.contains("vimalrajpara2006@gmail.com")) {
                    result = Integer.parseInt(calId);
                }
            } while (managedCursor.moveToNext());
        } else {
            Log.i(DEBUG_TAG, "No Calendars");
        }

        return result;

    }

您可以根据该 ID 添加事件以及进行搜索。

private Uri MakeNewCalendarEntry(int calId/*Value received from ListSelectedCalendars function*/) {
        ContentValues event = new ContentValues();

        event.put("calendar_id", calId);
        event.put("title", "Today's Event [TEST]");
        event.put("description", "2 Hour Presentation");
        event.put("eventLocation", "Online");

        long startTime = System.currentTimeMillis() + 1000 * 60 * 60;
        long endTime = System.currentTimeMillis() + 1000 * 60 * 60 * 2;

        event.put("dtstart", startTime);
        event.put("dtend", endTime);

        event.put("allDay", 0); // 0 for false, 1 for true
        event.put("eventStatus", 1);
        event.put("visibility", 0);
        event.put("transparency", 0);
        event.put("hasAlarm", 0); // 0 for false, 1 for true

        Uri eventsUri = Uri.parse(getCalendarUriBase()+"events");

        Uri insertedUri = getContentResolver().insert(eventsUri, event);
        return insertedUri;
    }
