Java 不幸的是，Android Emulator中的应用程序已停止

我在模拟器上运行我的应用程序，当我点击俱乐部按钮时，它就会崩溃，并给出消息“不幸的是，应用程序在Android模拟器中停止了”。我已经查看了logcat，它说要检查它在清单文件中声明的。所以我不知道该怎么办。我将展示布局文件、java文件和清单文件的代码。任何帮助都将不胜感激

}您在清单中错误地声明了您的活动

比如你写的

<activity
        android:name="ie.gmit.pleasework.Societies"
        android:label="@string/airsoft" >
    </activity>

应该把

<activity
        android:name=".Societies"
        android:label="@string/airsoft" >
    </activity>

---

类的名称取自应用程序的根（

ie.gmit.pleasework

）。通过两次编写完整的程序包，你让Dalvik找到类

ie.gmit.pleasework/ie.gmit.pleasework.Societies

发布你的日志，而不是你对错误的解释是的，只是忘了把它和我试图了解的所有其他东西放在一起。现在该起床了。谢谢你的MainActivity代码。所以只需完全忽略包名，当我单击“赞助商”按钮时，它就可以工作了？总体而言，通过编写。Societies（例如）你告诉Dalvik查看应用程序整体包的根包（在这种情况下，你告诉它查找ie.gmit.pleasework.Societies类）。我不知道你说的赞助商按钮是什么意思；它似乎没有出现在您添加到问题中的代码中。好的，所以我更改了它，现在logcat中的新条目是04-29 20:28:07.264:E/AndroidRuntime（1144）：java.lang.RuntimeException:无法启动活动组件信息{ie.gmit.pleasework/ie.gmit.pleasework.Societies}：java.lang.ClassCastException:android.widget.ImageButton在运行后无法转换为android.widget.ButtonCreat。刚刚将Button的所有实例更改为ImageButton。谢谢你的帮助。感激
