Android 当我插入线性布局时，我得到'；应用程序意外停止'；错误

我是一个android新手，最近开始学习

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

清理并重建你的应用程序

有时，在编辑资源XML文件并重新排序、添加或删除带有

@+id

标识符的元素时，生成的

R.java

和编译的二进制XML资源文件之间的id号会弄乱。当请求具有

findViewById（）

的视图时，该id与其他视图匹配，并且试图将结果强制转换为其他类型可能会导致

ClassCastException

---

这是使用ADT的Android开发人员必须了解的：构建依赖系统并不真正可靠，当与资源相关的东西不能正常工作时，首先清理并重新构建，看看它是否解决了问题。

你可以做得比“应用程序废话”更好。。发布正确的错误消息“应用程序激励我！意外地停止了。请再试一次。哈哈，分享你的logcat日志@SercanOzdemir我是这整件事的新人，我不知道如何向你展示我的logcat MSG，我已经编辑了这篇文章，希望能有所帮助。清理和重建。看起来您的资源标识符在生成的R.java和二进制资源XML文件之间不同步。
