SwipeRefreshLayout中的RecyclerView不是"wrap_content" [英] RecyclerView in SwipeRefreshLayout not "wrap_content"

问题描述

我有一个 RecyclerView 作为 SwipeRefreshLayout 的唯一子代，我想要RecyclerView wrap_content .当我将它们都设置为"wrap_content"时，它不起作用.内容较少的 RecyclerView 也是 match_parent .当我删除 SwipeRefreshLayout 时， RecyclerView 将 wrap_content .谁能帮我?我的英语不好，也许你听不懂.有人可以帮助我吗?非常感谢.

I have a RecyclerView as the only child of SwipeRefreshLayout, I want the RecyclerView wrap_content. When I set both of them "wrap_content", it doesn't work. The RecyclerView with fewer items also match_parent. When i delete SwipeRefreshLayout, the RecyclerView will wrap_content. Can anyone help me? My English is poor, Maybe you cann't understand. Anyone can help me? Thank you very much.
