Android Google Analytics (R.id) 重命名按钮

Question

Button createEventButton = (Button)findViewById(R.id.NewEventButton);

Button createPageButton = (Button)findViewById(R.id.NewPageButton);

你好 我已经搜遍了，但我不明白。我应该将“NewEventButton”更改为“button01”之类的东西吗？ 问题是，如果我更改它，按钮将停止工作，正常单击按钮时，它会打开手机浏览器并导航到网站。

同样的情况也发生在“NewPageButton”上，例如 Eclipse 要求也更改为“button01”。

如果我让它们保持原样，我会出现“不能成为解析器或不是字段”之类的错误

提前致谢

更新 这是主要的xml文件，

听起来您正在重命名它但没有更改 XML 布局 ID 名称，因此 R.java 没有新名称。如果您也在更改 XML，那么您不会重新编译项目。确保在 Eclipse 环境中选择了自动编译。转到 Project -> Build Automatically 并确保它旁边有一个复选标记。

----备选建议---- 您使用的是什么版本的 eclipse 和 ADB...您可能必须升级到最新的并重新安装 ADB....我遇到了类似的编译错误，只有升级和重新安装才有效。你的代码对我来说编译得很好。不确定您将如何使用其中一些方法，并且您确实有 4 个听众在听同一个按钮 R.id.button01。这是您在我的 Eclipse 中运行的代码：
