23.2.0 后具有大空白空间的 RecyclerView 项目 [英] RecyclerView items with big empty space after 23.2.0

问题描述

在我的 RecyclerView 中更新到 v23.2.0 后，我的项目之间有巨大的垂直空白空间.

After update to v23.2.0 in my RecyclerView I have items with huge empty vertical space, between the items.

我的项目布局非常简单:

My item layout is very simple:

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

推荐答案

根据 文档

在 23.2.0 版本中，LayoutManager API 有一个令人兴奋的新功能:自动测量！
这允许 RecyclerView 根据其内容的大小调整自身的大小.这意味着以前不可用的场景，例如将 WRAP_CONTENT 用于 RecyclerView 的维度，现在可以实现.
您会发现所有内置的 LayoutManager 现在都支持自动测量.

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视图的布局参数:以前忽略的布局参数(例如 MATCH_PARENT在滚动方向)将现在完全尊重.

Due to this change, make sure to double check the layout parameters of your item views: previously ignored layout parameters (such as MATCH_PARENT in the scroll direction) will now be fully respected.

在您的项目布局中，您必须更改:

In your item layout you have to change:

android:layout_height="match_parent"

与

android:layout_height="wrap_content"
