你发送了太多的代码，这就是为什么你没有得到答案。阅读日志并过滤代码，然后提出问题。我们无法为你做所有事情。 –

提示：查看Home.java中的第23行（注意LogCat的一部分？），然后尝试弄清楚为什么要将'RelativeLayout'投射到'Button'。正如塞尔吉奥所说，我们无法做到这一切。 – Eric

答

首先，请尝试清洁您的项目（例如，项目>从Eclipse主菜单清洁）。如果这没有帮助，显然中的RelativeLayout的值有错误的android:id值。使用哪个ID将根据您的Home.java类的第23行，无论哪一行。

你可能更具体，因为main-page.xml是另一个java文件。我的home.java应该链接到home.xml，所以我有点糊涂？ – user1890159

答

你不值得，但是：

12-11 11:36:27.291: E/AndroidRuntime(336): Caused by: java.lang.ClassCastException: android.widget.RelativeLayout 
    12-11 11:36:27.291: E/AndroidRuntime(336): at com.example.decrypter.Home.onCreate(Home.java:23)

这意味着......在com.example.decrypter.Home.OnCreate，上线23所强制转换的东西RelativeLayout的，而且相对不布局！

学会阅读，你必须，年轻padwan！

“你不值得”如果你不想帮助人们学习，不要参与。没有必要对此发表任何暗示。 – Sam

我对这个领域非常陌生，我读过它们，但我不明白。我要投射到相对不相对的布局。我定义一个按钮，并将其链接到xml页面，这是相对布局 – user1890159

似乎该行是'btn_about =（Button）findViewById（R.id.btn_about）;'按钮可能会在内部使用相对布局，如果你想检查来源。可能你的XML布局或视图ID有问题。 – Budius
