Java Android方向改变崩溃

我在

LinearLayout

中编写了由

TextView

和

EditText

组成的自定义视图

但是在

方向改变时

我得到了这个错误：

感谢您的建议。

我找到了问题的

解决方案

正如
错误告诉我的那样，问题出在
糟糕的演员阵容中

正如我所说，我有许多
自定义视图
，它们都由两个组件组成：
TextView
和一些
输入类型视图
。所有
文本视图
和所有
输入类型视图
具有相同的
Id
-s，尽管其类型不同

例如，如果我有两个
自定义视图
，
编辑文本类型
和
微调器类型
，在方向更改时，android试图
将
编辑文本
保存状态
转换为
微调器
保存状态
，应用程序崩溃

所以我只是更改了
Id
-s，一切都很顺利

感谢大家的帮助。
使用onSavedInstanceState恢复方向更改时的活动是否将布局显示为微调器中的一项？活动代码缺失，从堆栈跟踪中我看到您试图执行错误操作cast@SherifelKhatib不，我只是在主布局中使用
