Question

当我以编程方式创建日历事件时，我遇到了一个奇怪的问题它总是被称为生日日历（类型）我没有任何线索为什么它注意到这一点。

我使用的代码如下：Xamarin C＃

ContentResolver cr = ((Activity)Forms.Context).ContentResolver;
ContentValues values = new ContentValues();
String eventUriString = "content://com.android.calendar/events";

//Insert Events in the calendar...
values.Put(CalendarContract.Events.InterfaceConsts.CalendarId, 1);
values.Put(CalendarContract.Events.InterfaceConsts.Title, title);
values.Put(CalendarContract.Events.InterfaceConsts.Status, 1);
values.Put(CalendarContract.Events.InterfaceConsts.Description, description);
values.Put(CalendarContract.Events.InterfaceConsts.Dtstart, GetDateTimeMS(year, month, day, hour, minute));
values.Put(CalendarContract.Events.InterfaceConsts.Dtend, GetDateTimeMS(year, month, day, hour, minute));
values.Put(CalendarContract.Events.InterfaceConsts.AllDay, allday ? "1" : "0");
values.Put(CalendarContract.Events.InterfaceConsts.HasAlarm, hasalarm ? "1" : "0");
values.Put(CalendarContract.Events.InterfaceConsts.EventColor, Android.Graphics.Color.Green);
values.Put(CalendarContract.Events.InterfaceConsts.EventTimezone, "GMT+" + zone + ":00");
values.Put(CalendarContract.Events.InterfaceConsts.EventEndTimezone, "GMT+" + zone + ":00");
cr.Insert(Android.Net.Uri.Parse(eventUriString), values);

请某人有任何提示或想法可以指向正确的方向吗？

提前致谢。

有些设备使用日历ID = 1作为生日，但通常不会。因此，要获取特定设备的正确日历ID（对应于使用日历应用程序配置的电子邮件ID），请使用以下代码：

private int getCalendarId(Context context){

  Cursor cursor = null;
  ContentResolver contentResolver = context.getContentResolver();
  Uri calendars = CalendarContract.Calendars.CONTENT_URI;

  String[] EVENT_PROJECTION = new String[] {
        CalendarContract.Calendars._ID,                           // 0
        CalendarContract.Calendars.ACCOUNT_NAME,                  // 1
        CalendarContract.Calendars.CALENDAR_DISPLAY_NAME,         // 2
        CalendarContract.Calendars.OWNER_ACCOUNT,                 // 3
        CalendarContract.Calendars.IS_PRIMARY                     // 4
};

  int PROJECTION_ID_INDEX = 0;
  int PROJECTION_ACCOUNT_NAME_INDEX = 1;
  int PROJECTION_DISPLAY_NAME_INDEX = 2;
  int PROJECTION_OWNER_ACCOUNT_INDEX = 3;
  int PROJECTION_VISIBLE = 4;

  cursor = contentResolver.query(calendars, EVENT_PROJECTION, null, null, null);

  if (cursor.moveToFirst()) {
    String calName;
    long calId = 0;
    String visible;

    do {
        calName = cursor.getString(PROJECTION_DISPLAY_NAME_INDEX);
        calId = cursor.getLong(PROJECTION_ID_INDEX);
        visible = cursor.getString(PROJECTION_VISIBLE);
        if(visible.equals("1")){
            return (int)calId;
        }
        Log.e("Calendar Id : ", "" + calId + " : " + calName + " : " + visible);
    } while (cursor.moveToNext());

    return (int)calId;
  }
  return 1;
}

注意事项： IS_PRIMARY_COLOUM，如果是电子邮件ID，则返回1，而不是bithdays和假日。

请参阅：https://developer.android.com/reference/android/provider/CalendarContract.CalendarColumns.html#IS_PRIMARY了解详情。

Pkosta指向正确的方向。您必须采用VISIBLE和IS_PRIMARY的第一个日历。

long calId = 0;
String selection = CalendarContract.Calendars.VISIBLE + " = 1 AND " 
+ CalendarContract.Calendars.IS_PRIMARY + " = 1";

Uri calendarUri = CalendarContract.Calendars.CONTENT_URI;
Cursor cur = cr.query(calendarUri, null, selection, null, null);

if (cur != null && cur.moveToFirst()) {
  Get the field values
  calID = cur.getLong(CalendarContract.Calendars._ID);
}
if (cur != null) {
  cur.close();
}

return calId;

下面回答的问题已经过时了，请参阅Pkosta's答案，该答案提供了更准确的答案......

您必须将CalendarId值设为3而不是1，这是默认的生日日历。例如

 values.Put(CalendarContract.Events.InterfaceConsts.CalendarId, 1);

将其更改为

values.Put(CalendarContract.Events.InterfaceConsts.CalendarId, 3);

它为我解决了同样的问题。
