我对不同的布局和设备配置更改有问题

应用程序有3个feed_活动布局（默认、横向和平板电脑）

默认值：

    <?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:id="@+id/feeds_fragment_container">

</FrameLayout>

这里有一个例外：

当我将设备方向从横向更改为纵向时，会出现此异常。所以，当第一次启动它时，一切都很好，将设备旋转到横向模式也很好，但当我将其旋转回纵向模式时，它会崩溃，只有一个例外

以下是我的布局结构：

我在调试它，发现feed活动布局正确膨胀，甚至

子节点碎片的布局也正确膨胀，但比它崩溃了，我无法确定它崩溃的确切位置。
如果您的子节点碎片上有setRetainInstance（true）
，则会导致此错误。结果是：
活动开始，创建您的FeedsFragment
并将其添加到feeds\u fragment\u容器中
——我们不在横向视图中，因此没有子节点fragment
旋转屏幕（销毁活动）——FeedsFragment
被保留或重新创建，以及新的子节点Fragment
，因为我们现在处于横向
再次旋转屏幕（回到纵向-活动被破坏）。之所以会出现异常，是因为在子节点片段上设置了setRetainInstanceState（true）
。片段将被还原到其放入的原始视图ID中（R.ID.subnodes\u fragment\u container
），该视图ID不存在；导致异常

在子节点片段上删除setRetainInstance（true）
将防止发生此异常。
@Alex Townsend的答案是正确的，以防您不打算setRetainInstance（true）

如果您打算使用setRetainInstance（true），以便片段实例/状态可以在UI的不同时间/状态（如方向更改）显示在不同的视图（容器）中，那么我们需要手动处理片段的实例或状态。
这需要完成，因为片段管理器不允许2个用例：
已附加到视图A的片段不能直接附加到其他视图/容器。在这种情况下，将引发以下异常：IllegalStateException:无法更改片段的容器ID

“FragmentManager”无法管理其视图/容器已销毁的片段（比如配置更改），并引发java.lang.IllegalArgumentException:在活动的启动上未找到id XXXXX的片段YYYY
在我的例子中，我想在纵向模式和横向模式下在表格布局（viewpager）中使用相同的片段，这应该从表格布局移到不同的视图中
修复方法：您需要一个事务来从FragmentManager中删除片段，同时保留片段实例/状态，并创建一个新的add/replace事务来将实例/状态设置为新的（相同/不同）视图。有关代码解决方案，您可以参考答案。如果您正在跟踪，请记住您拥有的片段实例是新的，因此需要在片段的onCreate中手动读取保存的状态，并将UI状态重置为previous。您是否将布局放置在适当的文件夹中，如6英寸平板电脑的layout-sw600dp等。您的资源目录是什么平板电脑的横向/平板电脑布局？布局-sw600dp，平板电脑的横向和仅为默认布局@Raghunandanlayout-sw600dp，平板电脑的横向布局和仅为默认布局@AlexTownsend，发生错误的设备是什么？我找了这么多小时。它救了我一天…谢谢你@Alex Townsend虽然你的答案是正确的，但万一我打算设置restaininstance（true），该怎么办？
