android - Material Complex UI with Coordinate layout + Tablayout + Viewpager +recyclerview

Question

您好，我正在开发具有一些复杂 UI 功能的应用程序 ，我需要一些建议来使用新的 Material 设计来构建它 功能。但我遇到了一些问题。在此先感谢。

在横幅图像下方到 viewpager 我已经构建了它。但现在在横幅上方我正在使用回收 View 。当我单击该项目时需要根据顶部回收 View 更改整个布局包含单击..例如南印度单击更改整道菜都照着做...然后加上中文等等..

请建议我正确的方法。

代码是下面带有 Material Design 的红色标记内容设计..

Answer 1

您可以将 TabLayout 与 ViewPager 一起使用，并为选项卡的每一页放置 fragment 。每个 fragment 布局都可以包含您需要的 recyclerview

见:

https://github.com/codepath/android_guides/wiki/Google-Play-Style-Tabs-using-TabLayout

这将实现您的目的并且最容易处理
