生日數據在更新後被刪除

Question

我一直試圖在我的聯繫人列表中添加/更新生日。我可以添加生日，但是我更新生日時遇到問題。

更新後等待幾秒鐘，生日數據消失/被刪除。

我注意到，剛剛更新的生日後，「髒」字段被設置爲「1」，我猜觸發同步機制（我剛開始帶觸點）

下面是摘錄我使用

INSERT/ADD BIRTHDAY

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(); 
    } 

UPDATE BIRTHDAY

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(); 
    }

我發現問題了！

由於格式不正確，數據被刪除。

看起來，月份和日期字段中的前導零是重要的。我注意到的一件事是，當插入新的生日時，如果沒有前導零，則無關緊要。

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