Java的eclipse实现Android编程开发app实现井字棋的功能，要求给出MainActivity和layout布局的代码，并且不要导入Androidx的包而是用Android的包，获取地址时要正常获取不要报错
好的，下面是一个简单的井字棋（Tic-Tac-Toe）游戏的实现，使用Java和Eclipse进行Android开发。我们将创建一个MainActivity和相应的布局文件activity_main.xml。为了避免使用Androidx的包，我们将使用传统的Android包。

请确保在Eclipse中创建一个新的Android项目，并将上述代码分别放入相应的文件中。这样，你就可以运行一个简单的井字棋游戏了。
