这是我的总体代码，当我第一次运行我的应用程序时，它可以正常工作，但是当我重置它并倾向于单击任何按钮时，应用程序就会卡住而不响应。单击重置后，我无法单击主窗口上的任何预设按钮，我必须将其强制关闭，因为它卡住了。我检测到重置游戏后，当我单击按钮时，它会生成事件以进入startgame（）函数，但正在开始循环并在同一函数中生成多个事件

答案 0 :(得分：0)
在测试验证中，您测试按钮是否等于一个空格：x.equal(" ")（startGame）
但是当您重置游戏时，会将ButtonText设置为空：A1.setText("");（resetGame）
"" != " "，因此您需要在重置的每个按钮中添加一个空格或确认其为空。
此外，您在startGame的else中调用startGame，所以由于条件为假，您将陷入无限循环
