Question

我有一些问题。当我更改任何xml文件时，我在主布局初始化时遇到错误（我确定只有小布局）。例如，如果我在安装向导片段上再添加一个字段，则会出现该错误：

我可以在哪里获取有关我做错的信息？

更新1

StatusFragment.java中的第80行

statusText = (TextView) view.findViewById(R.id.statusText);

它真的是TextView。此外，我甚至不接触那些文件。

初学者：

您可以从git中获取代码：

git clone git://git.linphone.org/linphone-android.git

如果您想要整个项目，请准备好构建，请使用--recursive标记。

Answer 1

转到Project-＆gt;在Eclipse中清理，让它完成然后再次运行你的应用程序，一切都会正常工作。

Eclipse根据布局中视图的顺序缓存您的资源ID。如果你改变它可能会得到classcastexception。清理项目会强制Eclipse正确地重新缓存所有ID。

更改的布局会引发运行时错误
