二进制XML文件行#8:膨胀类片段时出错，原因是：android.view.InflateException:

我已经读了很多关于stackoverflow异常的文章（如果您出于同样的原因来到这里，您可以查看提示，或者。我的应用程序在纵向模式下运行正常，但在横向模式下我会出现此错误。根据其他帖子，原因可能会有所不同。一种流行的方法是使用

支持库

，但我不确定这是否是解决方案，因为我的

问题在于试图借助

getActivity（）.findViewById（…）

获取视图。我使用了基于支持库的代码示例，该库没有

getView（）

方法。使用

getView（）

解决了问题。

发布xml布局。@JDev My bad，意外发布未完成的java代码。@Mike M是的，这是我获取适配器列表的地方。它在纵向上运行良好，但我不明白为什么它在景观中不起作用，有些地方使用的是未初始化的视图引用\
