android - RecyclerView 23.2.0 后有大空间的项目

Question

在我的 RecyclerView 中更新到 v23.2.0 后，我的项目之间的垂直空间很大。

我的项目布局很简单:

 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
       android:layout_width="match_parent"
       android:layout_height="match_parent"                                    
       android:orientation="vertical" >

Answer 1

根据doc

With the release 23.2.0 there is an exciting new feature to the LayoutManager API: auto-measurement!
This allows a RecyclerView to size itself based on the size of its contents. This means that previously unavailable scenarios, such as using WRAP_CONTENT for a dimension of the RecyclerView, are now possible.
You’ll find all built in LayoutManagers now support auto-measurement.

由于此更改，请务必仔细检查项目 View 的布局参数:以前忽略的布局参数(例如 MATCH_PARENT滚动方向)将现在得到充分尊重。

在你的项目布局中你必须改变:

android:layout_height="match_parent"

与

android:layout_height="wrap_content"
