我的应用程序在启动时停止
所以我刚开始用java编程，并尝试制作一个TicTicToeGame，它成功了:)问题是，你只能玩1个TicTacToe游戏，所以我想制作一个按钮来重启游戏和一个按钮退出比赛。由于我添加了这个并尝试在我的手机上运行它，它在我启动时崩溃了。这是我的MainActivity.java：

答案 0 :(得分：0)
您需要这样做才能MainActivity实现View.OnClickListener：
public class MainActivity extends ActionBarActivity implements View.OnClickListener { ...
然后单击按钮时将调用onClick方法。

它在这里工作，因为我不使用appcompact 7进行开发，我使用activity来扩展你的类，我也没有使用你的menu.xml，首先删除那个文件并尝试构建你的代码，如果这不起作用这个文件在游戏重启和应用程序关闭时工作正常。
谢谢使用此功能，如果有任何问题，请回来。
看到它在这里工作
