回答1:

private int UpdateCalendarEntry(int entryID) {
    int iNumRowsUpdated = 0;

    ContentValues event = new ContentValues();

    event.put("title", "Changed Event Title");
    event.put("hasAlarm", 1); // 0 for false, 1 for true

    Uri eventsUri = Uri.parse(getCalendarUriBase()+"events");
    Uri eventUri = ContentUris.withAppendedId(eventsUri, entryID);

    iNumRowsUpdated = getContentResolver().update(eventUri, event, null,
            null);

    Log.i(DEBUG_TAG, "Updated " + iNumRowsUpdated + " calendar entry.");

    return iNumRowsUpdated;
}
