JFrame完全没有响应。 [英] JFrame doesn't responds at all.

问题描述

我使用java制作了一个语音呼叫应用程序。该帧由两个按钮组成，一个是呼叫，另一个是切断呼叫。我的问题是每当我按下呼叫按钮时线程开始运行并且数据（语音）连续传输，但其他操作（如剪切按钮或帧关闭按钮）根本不响应。就像框架挂起一样。有人可以帮我解决这个问题吗？



这是我的客户代码。没有使用任何框架的服务器。它只能在另一台机器上运行。

I made a voice call application using java. the frame consists of two buttons one is to call and another is to cut the call. My problem is whenever i press the call button the threads starts running and the data(voice) is transmitted continuously but the other operations such as the cut button or frame close button doesn't respond at all. it is as if the frame hangs. can someone help me out with this?

this is my client code. haven't used any frames for server. it just runs on another machine.

推荐答案

函数属于在单独的线程中调用并切断它，而不是在主线程中.....

functions belongs to call and cut wright it in separate threads,not in main threads.....
