带有选项卡和 Viewpager 的 Android fragment

Question

我们正在构建一个应用程序，如上所示，它嵌套了 fragment 。

1. 特色标签 - 详细信息标签和 MAps 标签
2. “详细信息”选项卡将有一个幻灯片 - 类似于“查看页面 slider ”和下方可滚动的信息。
3. 将显示 map 的“ map ”选项卡。

我已经实现了选项卡和 map 以及 slider ，如上所示。现在我很困惑如何在 slider 下方添加内容，这将使详细信息选项卡可滚动。

我尝试了什么？

在单击“详细信息”选项卡时，Fragment 将尝试在其中扩充两个 Fragment 布局。

Answer 1

请注意，从 Android 4.2 或最新的兼容库开始支持 Fragments 嵌套。以前它根本不受支持。至于下面的内容- 把它们都放在一个容器里就可以了
