Android-未找到片段的视图，正在更改片段
您好，目前我正在Android Studio上进行一个Android项目，我可以使用FragmentPagerAdapter切换片段，每个片段都使用根片段，因此当我使用一个片段时，它工作得非常好，但当我想要实现第二个片段时，它给了我以下错误：Android-未找到片段的视图，正在更改片段,android,android-fragments,Android,Android Fragments,您好，目前我正在Android Studio上进行一个Android项目，我可以使用FragmentPagerAdapter切换片段，每个片段都使用根片段，因此当我使用一个片段时，它工作得非常好，但当我想要实现第二个片段时，它给了我以下错误： java.lang.IllegalArgumentException: No view found for id 0x7f0c00ae (net.beardboy.aarcapp:id/root_frame_graphs) for fragment Gra

问题可能是因为您夸大了错误的布局（XML）-这意味着该布局文件中可能不存在
R.id.root\u frame\u图形。
您希望在布局文件中找到类似的内容（使用FrameLayout
）：
传递到FragmentTransaction.replace（）中的ID（R.ID.root\u frame\u graphs
）必须是setContentView（）中指定布局的子级，我建议您在问题中包含该布局。我怀疑您可能面临与已解决的问题相同的问题请您为Graph Fragments添加代码您可以为您的活动的onCreate添加代码，然后还包括您声明片段的XML吗？您好，感谢更新，请包括活动onCreate的代码。给你，谢谢@ishmaelMakitlaGreat！现在，就您的情况而言，请向我们展示布局的XMLactivity\u main
，虽然您可能认为错误布局文件的概念被夸大是正确的，但句子明确地说，您必须在XML文件中同时包含两个片段，在使用上下文中replace（）
，这将取消整体资格answer@MarcinOrlowski,我理解你的观点-但也许我被误导了，他指的是两个不同的ID-root\u frame\u actividades
和root\u frame\u graphs
-这让我觉得他两者都有“占位符”…我希望这是有意义的。但你的回答仍然是我引用的句子，这完全是错误的，由于您无法从代码中删除未添加的片段。
