Java Android TCP/IP和GUI与其他线程通信-Tic Tac Toe多人游戏

这就是交易。我想用Android实现多人游戏Tic-Tac-Toe。我使用Java部署了多线程服务器，但在客户端上遇到了麻烦。据我所知，您应该使用后台线程来处理通信，而将UI线程留给UI处理。我在开发游戏循环和线程通信时遇到了一些问题。我决定使用处理程序而不是异步任务

我认为循环应该在后台线程中实现，看起来有点像这样： 使用处理程序从UI获取信息 将数据写入服务器的输出流 从服务器的输入流中读取数据 处理数据 使用其他处理程序将数据发送到UI

我正在使用Eclipse和仿真器作为客户机进行测试。问题是我无法设置处理程序。一个处理程序UIHandler作为参数发送给ClientThread构造函数，而Net处理程序则通过一个方法从客户端线程获取到UIThread

我读到我需要使用活套来处理传入的数据。我不能在一个无休止的循环中调用handleMessage方法吗？我真的不知道如何部署这个。我很乐意接受任何意见

代码尚未完成，因此某些方法可能看起来很奇怪。我对解决UIThread到BackGroundThread到服务器的通信很感兴趣。没有其他内容。

处理程序

线程内运行的
循环器
。您的后台线程需要创建自己的
活套
（或者使用
HandlerThread
为您处理
活套
），然后您的后台线程需要将其

传回主UI线程
