问题描述
我已将我的 Android Studio 更新到 3.1 稳定版.我注意到调色板窗口中的所有"选项卡被删除并引入了传统"选项卡.该选项卡包含以下内容:
I've updated my Android Studio to 3.1 stable channel. I've noticed that "All" tabs in palette window are removed and "Legacy" tab is introduced. That tab contains the following:
- 列表视图
- TabHost
- 相对布局
- 网格视图
我没有提到 GridLayout 因为它是可下载的依赖项，而不是来自 Android API 的视图.
I didn't mention the GridLayout because it's a downloadable dependency rather than a View from the Android APIs.
哪些新视图取代了上面提到的视图?
Which new Views have replaced the views mentioned above?
我知道 ConstraintLayout 替换了 RelativeLayout，但是什么替换了 ListView、GridView 或 标签主机?我想了解最新情况.
I know ConstraintLayout replaces RelativeLayout, but what replaces the ListView, the GridView or the TabHost? I want to be up-to-date.
推荐答案
ListView - 替换为 RecyclerView
TabHost - 替换为 TabLayout
RelativeLayout - 替换为 ConstraintLayout
GridView - 替换为 ConstraintLayout
主要是因为新的性能更好.
Mostly due to the new ones having better performance.
RecyclerView.Adapter 实现了流行和推荐的持有者模式，并支持现代布局转换.它还接受布局管理器，允许您轻松实现网格.
RecyclerView.Adapter has implemented the popular and recommended holder pattern and supports modern layout transitions. It also accepts a layout manager allowing you to easily implement a grid.
