我目前正在为我的应用程序使用领域，但是当我读取 n 写入此错误显示时，我已经检查了两者beginTransaction()并且commitTransaction()也正确使用但它仍然显示

错误：

代码片段是：

 HashMap<String,String> msg = (HashMap)dataSnapshot.getValue();
        Message message = new Message();
        message.setSender(msg.get(COLUMN_SENDER));
        message.setText(msg.get(COLUMN_TEXT));
        message.setTime(msg.get(COLUMN_TIME));
        message.setStatus(msg.get(COLUMN_STATUS));

        try {
            Realm realm = Realm.getInstance(realmConfig);
            Realm realm2 = Realm.getInstance(realmConfig);

            message.setDate(sDateFormat.parse(SnapshotKey));
          //  Hawk.put(SnapshotKey, message);
            RealmResults<MessageRealm> result = realm.where(MessageRealm.class)
                    .equalTo("key", SnapshotKey)
                    .findAll();
            if (result.size()==0){
                realm.beginTransaction();
                MessageRealm messageRealm=realm.createObject(MessageRealm.class);
                messageRealm.setSender(msg.get(COLUMN_SENDER));
                messageRealm.setText(msg.get(COLUMN_TEXT));
                messageRealm.setStatus(msg.get(COLUMN_STATUS));
                messageRealm.setTime(msg.get(COLUMN_TIME));
                messageRealm.setKey(SnapshotKey);
                messageRealm.setChatWith(ReciOtherEmail);
                realm.commitTransaction();

                String userEmailKeyY=ReciOtherEmail;
                String keyEmail=userEmailKeyY;
                Log.e("SahajLOG5", "KeyEmail  " + userEmailKeyY);
                Log.e("SahajLOG", "REALM ADDED TRANSACTION  INITIATED   ");
                RealmResults<ToTal_ProfileModelRealmClass> resultForProfileInfo = realm2.where(ToTal_ProfileModelRealmClass.class)
                        .equalTo("userEmailKey", keyEmail)
                        .findAll();
                Log.e("SahajLOGL", "REALM REsult <--CorrectionLegacy--> " + resultForProfileInfo);
                if(resultForProfileInfo.size()!=0){
   -->                 realm2.beginTransaction();
   -->                 currentChatRealmModelClass obj=realm.createObject(currentChatRealmModelClass.class);
   -->                 obj.setUserEmailKey(keyEmail);
   -->                 obj.setMessage(msg.get(COLUMN_TEXT));
   -->   obj.setHashname(resultForProfileInfo.get(0).getHashname());
   -->  obj.setUserNAME(resultForProfileInfo.get(0).getUserNAME());
   -->  obj.setPicOfllineName(resultForProfileInfo.get(0).getPicOfflineName());
   -->                 obj.setPicurl(resultForProfileInfo.get(0).getPicurl());
   -->                     realm2.commitTransaction();
                }

            }



        }catch (Exception e){
            Log.d(TAG, "Couldn't parse data in MessageDataSource Class   " + e);
        }
        if(callbacks != null){
            callbacks.onMessageAdded(message);
        }

我已经标记了-->它实际发生的位置。

n 当我登录resultForProfileInfo课程时，它不为空

所以，我解决了这个问题，当我更清楚地查看 logcat 时，还有一个错误指出我已经有主键，它正在再次保存.. 所以，我创建了一个 realmClass 的新对象，然后在其中更新了它.

 -->     currentChatRealmModelClass obj=new currentChatRealmModelClass();//realm.createObject(currentChatRealmModelClass.class);
                    obj.setUserEmailKey(keyEmail);
                    obj.setMessage(msg.get(COLUMN_TEXT));
                    obj.setHashname(resultForProfileInfo.get(0).getHashname());
                    obj.setUserNAME(resultForProfileInfo.get(0).getUserNAME());
                    obj.setPicOfllineName(resultForProfileInfo.get(0).getPicOfflineName());
                    obj.setPicurl(resultForProfileInfo.get(0).getPicurl());
       -->          realm2.beginTransaction();
       -->          realm.copyToRealmOrUpdate(obj);
       -->          realm2.commitTransaction();
