android - 错误的交易状态(没有 Activity 的交易、错误的交易类型或交易已经在进行中)

Question

我目前正在为我的应用程序使用 Realm 但是当我读 n 写这个错误显示时，我已经检查了 beginTransaction() 和 commitTransaction() 也被正确使用但仍然显示

错误:

io.realm.exceptions.RealmError: Unrecoverable error. Wrong transactional state (no active transaction, wrong type of transaction, or transaction already in progress) in io_realm_internal_SharedGroup.cpp line 157

代码 fragment 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);
        }

我用 --> 标记了实际发生的地方。

n 当我记录 resultForProfileInfo 类时，它不是空的

Answer 1

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了主键，它又被保存了。所以，我创建了一个新的 realmClass 对象，然后更新了它在里面。

 -->     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();
