【问题描述】：

我正在使用 ejabberd 作为 xmpp 服务器和 aSmack API 在 android 中创建聊天多用户聊天

我正在使用以下代码

public boolean createGroup(XMPPConnection connection, String groupName) 
        /*
         * if (connection == null) return false; try 
         * connection.getRoster().createGroup(groupName);
         * Log.v("Group created : ", groupName); return true;  catch (Exception
         * e)  e.printStackTrace(); return false; 
         */
        if (getConnection() == null) 
            try 
                connect();
             catch (XMPPException e) 
                // TODO Auto-generated catch block
                e.printStackTrace();
            
        
        //configure(ProviderManager.getInstance());
        SmackAndroid.init(getApplicationContext());
        MultiUserChat muc = new MultiUserChat(getConnection(),
                "[e-mail]");

        try 
            muc.create("chitchat");
            Form form = muc.getConfigurationForm();
            Form submitForm = form.createAnswerForm();
            for (Iterator<FormField> fields = form.getFields(); fields.hasNext();) 
                FormField field = (FormField) fields.next();
                if (!FormField.TYPE_HIDDEN.equals(field.getType())
                        && field.getVariable() != null) 
                    submitForm.setDefaultAnswer(field.getVariable());
                
            
            List<String> owners = new ArrayList<String>();
            // Log.i(TAG, "list of owners=====" +owners.toString());
            owners.add("akash");
            submitForm.setAnswer("muc#roomconfig_roomowners", owners);
            muc.sendConfigurationForm(submitForm);

                new AdHocCommandDataProvider.SessionExpiredError());
    

但我收到以下错误

07-10 23:18:07.733：E/AndroidRuntime(707)：原因：java.lang.IllegalArgumentException：找不到指定变量的字段。 07-10 23:18:07.733: E/AndroidRuntime(707): at org.jivesoftware.smackx.Form.setAnswer(Form.java:326) 07-10 23:18:07.733: E/AndroidRuntime(707): at com.akash.locationaware.XMPPChatDemoActivity.createGroup(XMPPChatDemoActivity.java:308) 07-10 23:18:07.733: E/AndroidRuntime(707): 在 com.akash.locationaware.MessageActivity.sendMessage(MessageActivity.java:90) 07-10 23:18:07.733: E/AndroidRuntime(707): ... 14 更多

我无法理解我错过了什么以及这条消息的含义。

【参考方案1】：

问题是因为下面这行代码

submitForm.setAnswer("muc#roomconfig_roomowners", owners);

删除它让我的房间创建工作。
