了解重复的日历活动

Question

我正在尝试将事件添加到Android上的日历中。添加工作正常，但每次调用add事件方法时，都会创建重复项。我尝试更新事件，并删除具有特定标题的所有事件，但没有成功。

我的导入方法：

public static boolean importToCalendar(@NonNull Activity activity, CalendarEvent calendarEvent) {
        if (ActivityCompat.checkSelfPermission(activity, Manifest.permission.WRITE_CALENDAR)
                != PackageManager.PERMISSION_GRANTED)
            return false;

        removeExistingEvent(activity, calendarEvent);

        ContentValues event = new ContentValues();
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M)
            event.put(Events.CALENDAR_ID, 3);
        else
            event.put(Events.CALENDAR_ID, 1);

        event.put(Events.TITLE, calendarEvent.getTitle());
        event.put(Events.DESCRIPTION, calendarEvent.getDescription());
        event.put(Events.DTSTART, calendarEvent.getStartTime());
        event.put(Events.DTEND, calendarEvent.getEndTime());
        event.put(Events.STATUS, calendarEvent.getEventStatus());
        event.put(Events.HAS_ALARM, calendarEvent.getHasAlarm());
        event.put(Events.EVENT_TIMEZONE, TimeZone.getDefault().getID());

        Uri uri = activity.getContentResolver().insert(Events.CONTENT_URI, event);
        Log.d("calendar: ", "inserted " + uri);

//        long eventId = getLastEventId(uri);
        return true;
    }

其中removeExistingEvent是：

public static void removeExistingEvent(@NonNull Activity activity, CalendarEvent calendarEvent) {
        String[] proj =
                new String[]{
                        CalendarContract.Instances._ID,
                        CalendarContract.Instances.BEGIN,
                        CalendarContract.Instances.END,
                        CalendarContract.Instances.EVENT_ID};

        ContentResolver contentResolver = activity.getContentResolver();
        Cursor cursor = CalendarContract.Instances.query(
                contentResolver,
                proj,
                calendarEvent.getStartTime(),
                calendarEvent.getEndTime(),
                calendarEvent.getTitle());

        while (cursor.moveToNext()) {
            long id = cursor.getLong(cursor.getColumnIndex("_id"));
            Uri eventUri = ContentUris.withAppendedId(Events.CONTENT_URI, id);
            contentResolver.delete(eventUri, null, null);
            Log.d("calendar: ", "deleted" + id);
        }
    }

日志说：

W / ContentResolver：无法获取以下类型：content：//com.android.calendar（未知URL内容：//com.android.calendar）06-15 12：03：22.872 9934-9934 / com.ptr D / calendar :: deleted482 06-15 12：03：22.899 6312-6325 / com.android.providers.calendar W / ContentResolver：无法获取类型：content：//com.android.calendar（未知URL内容：// com。 android.calendar）06-15 12：03：22.918 9934-9934 / com.ptr D / calendar :: inserted content：//com.android.calendar/events/299

任何帮助将不胜感激。

尝试通过eventId删除，而不是按标题删除。你可以在Events: delete尝试。

service.events().delete(calendarId='primary', eventId='eventId').execute()
