我要实现群聊在我的应用程序，用于这一目的，我使用MUC聊天室实现相同的。

在这里我要添加成员的名单（我有JID的）房间。我想在内部将它们添加到列表中的所有成员。如何添加他们没有邀请他们。

和加入成员后，我希望实现的功能，每当聊天室的消息的用户或聊天，应该被传递到的所有其他用户

的主要问题是如何将成员添加到聊天室

code：

 私人无效createRoom（）{        MultiUserChat privateRoom =新MultiUserChat（连接testGroup@conference.abc.com）;        尝试{            privateRoom.join（高拉夫，123456）;            privateRoom.sendConfigurationForm（新表格（Form.TYPE_SUBMIT））;            的System.out.println（空间中创建的!!!）;            消息消息=新的消息（testGroup@conference.abc.com，Message.Type.normal）;            message.setBody（欢乐用户）;            privateRoom.sendMessage（消息）;        }赶上（XMPPException E）{            // TODO自动生成catch块            e.printStackTrace（）;        }    } 

解决方案

XEP-0045 不包含其中客户端被强制地作出的聊天室的参加者的情况。虽然你可以发送邀请联系人（或者直接到用户，或通过MUC服务器），接触实际上并没有加入该聊天室，直到接触的客户端请求加入聊天室。

因此​​，将用户添加到聊天室没有邀请他们需要在用户的客户端的特殊支持。可能的话，客户可以修改自动接受来自受信任的联系人聊天室邀请。

I want to implement Group Chat in my application, for that purpose i am using MUC chat rooms to implement the same.

Here I want to add a list of members( i have the JID's) to the room. I want to add them internally to all the members in the list. How can i add them without inviting them.

And after adding the members i want to implement a functionality that whenever a user of the chat room messages or chat, it should be delivered to all the other users.

The main problem is how to add members to the chat room

code:

private void createRoom(){

        MultiUserChat privateRoom = new MultiUserChat(connection, "testGroup@conference.abc.com");
        try {
            privateRoom.join("gaurav","123456");
            privateRoom.sendConfigurationForm(new Form(Form.TYPE_SUBMIT));
            System.out.println("Room Created!!!");

            Message message = new Message("testGroup@conference.abc.com", Message.Type.normal);
            message.setBody("Happy User");

            privateRoom.sendMessage(message);



        } catch (XMPPException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

    }

XEP-0045 doesn't contain a scenario where a client is forcibly made a participant of a chat room. While you can send an invite to a contact (either directly to the user, or through the MUC server), the contact doesn't actually join the chat room until the contact's client requests to join the room.

Thus, adding a user to a chat room without inviting them requires special support in the user's client. Possibly, the client could be modified to automatically accept chat room invites from trusted contacts.
