android - 更新后生日数据被删除

Question

我一直在尝试在我的联系人列表中添加/更新生日。我可以添加生日，但是更新生日时遇到问题。

更新后等待几秒钟，生日数据消失/被删除。

我注意到在更新生日之后，“dirty”字段被设置为“1”，我猜这会触发同步机制(我只是从联系人开始)

这是我正在使用的 fragment

插入/添加生日

    long rawContactId = -1;
    String[] projection = new String[]{ContactsContract.CommonDataKinds.Event.RAW_CONTACT_ID};
    String selection = ContactsContract.CommonDataKinds.Event.CONTACT_ID + "=?";

    String[] selectionArgs = new String[]{
        String.valueOf(bdayContact.getId())
    };

    Cursor c = getContentResolver().query(ContactsContract.Data.CONTENT_URI,
          projection,
          selection,
          selectionArgs, null);
    try {
        if (c.moveToFirst()) {
            rawContactId = c.getLong(0);
        }
    } finally {
        c.close();
    }

     ArrayList<ContentProviderOperation> ops = new ArrayList<ContentProviderOperation>();
     ops.add(ContentProviderOperation.newInsert(Data.CONTENT_URI)
         .withValue(ContactsContract.Data.RAW_CONTACT_ID, rawContactId)
         .withValue(ContactsContract.Data.MIMETYPE, ContactsContract.CommonDataKinds.Event.CONTENT_ITEM_TYPE)
         .withValue(ContactsContract.CommonDataKinds.Event.START_DATE, bday)
         .withValue(ContactsContract.CommonDataKinds.Event.TYPE, ContactsContract.CommonDataKinds.Event.TYPE_BIRTHDAY)
         .build());

     try {
        getContentResolver().applyBatch(ContactsContract.AUTHORITY, ops);
    } catch (RemoteException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (OperationApplicationException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

更新生日

String selection = ContactsContract.CommonDataKinds.Event.CONTACT_ID+"=? AND " +
ContactsContract.CommonDataKinds.Event.MIMETYPE+"=? AND " +
ContactsContract.CommonDataKinds.Event.TYPE+"=?"
                ;
String[] selectionArgs = new String[]{
                           String.valueOf(contacts.get(position).getId()),
                        String.valueOf(ContactsContract.CommonDataKinds.Event.CONTENT_ITEM_TYPE),
                        String.valueOf(ContactsContract.CommonDataKinds.Event.TYPE_BIRTHDAY)
                };

                Cursor cursor = managedQuery(ContactsContract.Data.CONTENT_URI, null, selection, selectionArgs, null);

                if(cursor.moveToFirst()){ 
                    int index = cursor.getColumnIndex(ContactsContract.CommonDataKinds.Event._ID);
                    String eventId = cursor.getString(index);

                    String bday = year+"-"+(monthOfYear+1)+"-"+dayOfMonth;
                }

ArrayList<ContentProviderOperation> ops = new ArrayList<ContentProviderOperation>();
     ops.add(ContentProviderOperation.newUpdate(Data.CONTENT_URI)
         .withSelection(ContactsContract.Data._ID + " = ?", new String[] {eventId})
         .withValue(ContactsContract.Data.MIMETYPE, ContactsContract.CommonDataKinds.Event.CONTENT_ITEM_TYPE)
         .withValue(ContactsContract.CommonDataKinds.Event.START_DATE, bday)
         .withValue(ContactsContract.CommonDataKinds.Event.TYPE, ContactsContract.CommonDataKinds.Event.TYPE_BIRTHDAY)
         .build());

     try {
        getContentResolver().applyBatch(ContactsContract.AUTHORITY, ops);
    } catch (RemoteException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (OperationApplicationException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

我找到问题了!

数据因格式不正确而被删除。

看来月份和日期字段中的前导零很重要。不过我注意到一件事，即在插入新生日时，如果没有前导零并不重要。

String bday = year+"-"+String.format("%02d", (monthOfYear+1))+"-"+String.format("%02d", dayOfMonth);
