【问题标题】：Screen Layout doesn't scroll屏幕布局不滚动

【问题描述】：

我有一个外部 ScrollView，其中有一个 RecyclerView 和三个选项卡。每个选项卡都有一个片段，该片段使用 ViewPager 加载到相应的选项卡中，但外部 ScrollView 不会滚动我的布局。我使用了嵌套的 ScrollView，但它也不滚动。也许我做错了什么。有人有建议吗？请与我分享。这是我的xml代码结构

【问题讨论】：

尝试从滚动视图中移除布局权重，并使用线性布局作为滚动视图的直接子级而不是相对布局。
感谢您在我如上所述在布局外侧添加滚动视图时的回复，然后每个选项卡受尊重的片段不显示数据，但是当我将该外部布局更改为滚动视图时，它会显示数据
您能举例说明您希望查看的方式吗？通常水平选项卡在滚动视图之外，您的 UI 看起来更复杂。
是否可以在滚动视图中添加选项卡以使其可滚动，因为我的要求看起来就是这样
我希望在具有标签 recyleview 和每个标签交叉响应片段加载的 recyclerview 的屏幕中全屏滚动

标签： android android-layout android-fragments android-scrollview android-tablayout

【解决方案1】：

您违反了 Android 的 UI 标准，这就是您永远无法实现目标的原因。尝试坚持 Android UI 标准并简化 UI。

我改变了我的屏幕布局结构，最后 ScrollView 工作了这是解决方案：
