我已经使用 aSmack 实现了一个聊天应用程序。我使用 openfire 服务器作为聊天服务器。所有这些应用程序都在同一台机器上运行。但是当我尝试在两个模拟器之间发送消息时，只有一个模拟器成功接收到消息。其他客户端不会收到任何消息。但是从两个模拟器我都能够向 pigin（IM clinet）发送消息。此外，如果我使用 gmail.com 作为聊天服务器，一切正常。

用于登录jayamal suchith的用户名（openfire表示用户在线）

用于发送消息的名称 jayamal@elearn （elearn 是我使用 openfire 在我的机器中创建的域）suchith@elearn
（但在 openfire 档案中显示一个名称为 jayamal@elearn/Smack，尝试向该名称发送消息但它也不成功）

请帮助纠正这个问题。非常感谢您的帮助。

抱歉，这有点晚了。

您可以发送到 IM 客户端 (pidgin) 的一个用户可以发送回您的模拟器。即您可以在任一模拟器中接收吗？

消息接收是基于事件的，因此您无需单击按钮即可将其关闭。

看看这个很好的例子。达瓦努姆·斯里尼瓦斯

我已经对其进行了广泛的修改以供我使用，但基本代码仍然非常有用。
