带有2个没有viewpager的标签的片段
[英]A fragment with 2 tabs without viewpager
问题描述
[我的抽屉菜单图片] [1]我有一个带有碎片导航抽屉的应用程序。 现在我想要一个片段里面有两个标签，每个标签另一个片段。 我搜索了几天的例子，但没有在Kotlin Code中找到一个。 它总是一个带有片段标签的活动，但从不带有2个标签的片段，每个片段都有一个片段。 谁能帮我？
在几周内搜索一个例子。 我只想通过点击它来更改标签，而不是滑动。

你想要完成什么
从你的问题的描述来看，你想要完成的真实事情就是在片段中放置一个TabHost（而不是一个Activity），因为你的导航抽屉将你带到一个片段，可能会取代当前显示的片段。
有什么问题？
您可能已经看到大多数TabHost示例都实现为一个Activity，然后托管在点击时显示片段的标签。 事实上，你描述的内容并没有什么特别的疯狂。
我该怎么办？
我个人会使用ViewPager而不是TabHost（你说你不想要滑动手势，并且有办法做到这一点 ），但无论你的解决方案如何，片段都可以显示Child（也称为嵌套）片段。 最重要的是要记住使用正确的FragmentManager（有一个getChildFragmentManager()方法而不是通常的）。
方法（如文档所述 ）：
返回一个私有FragmentManager，用于放置和管理此Fragment中的Fragment。
希望这能够推动您朝着正确的方向前进，现在您需要测试，实施和调试您的解决方案; 这些是您可以使用的一些工具。
当您实现此功能时，如果发现某些内容无法按预期运行，请不要犹豫，发布有关您的实施的具体问题。
祝好运！
