我希望有人可以提供帮助。
我有点难以解释活动,它是一个经典的视图寻呼机,但在操作栏中有一个按钮,使视图向右移动并显示菜单(原始隐藏在屏幕外)。这是一个类似Facebook的菜单。我有2个布局(菜单和寻呼机),我使用自定义ScrollView来获取我寻找的行为。
当我改变方向时,我希望菜单每次都出来。所以我创建了一个不同的布局,并测试了onCreate方法的方向。
我有几次尝试: 在清单中没有configChange的情况下,应用程序崩溃时出现“IllegalStateException:Activity已被破坏”,指向“mPager.setAdapter(mAdapter);”这一行。
配置更改时,应用程序在旋转时会执行废话,它不会将布局更改为布局中的布局...
配置更改和“onConfigurationChanged”上onCreate的内容从纵向到横向是好的,但反向出错(视图很大,因为它应该很高,而且应该很大)
我希望你们中的一个人不会感到困惑。
如果你愿意,我可以发布代码,但是有很多代码,我不知道哪个特定部分可以帮助你(只是问我)。
谢谢!

这就是清单中没有配置更改的代码,我抓住了错误,以便我的应用程序不会崩溃
答案 0 :(得分:0)
当屏幕方向改变时,Android会破坏您的活动并再次创建它。 因此,如果您的适配器持有对Activity的引用(可能是片段管理器),则会导致错误。
