当“废弃或附加的视图可能无法回收"时，RecyclerView 崩溃 [英] RecyclerView crashes when "scrapped or attached views may not be recycled"

问题描述

我正在使用 StaggeredGridLayoutManager 从 Android 网站获取的 RecyclerView 的简单实现，但我不断收到导致我的应用程序崩溃的错误:

I'm using a simple implementation of RecyclerView taken from the Android website using a StaggeredGridLayoutManager and I keep getting this error that crashes my app:

java.lang.IllegalArgumentException: Scrapped or attached views may not be recycled. isScrap:false isAttached:true

简单来说，我的字面意思是它与 此页面中的实现相同在他们的网站上，唯一的区别是我的网格项目的布局是一个 ImageView 和几个 TextView，所以我不会费心重新发布我的代码.

By simple, I literally mean it's the same implementation taken from this page on their website, the only difference being is that my grid item's layout is an ImageView and a couple of TextViews, so I won't bother reposting my code.

还有其他人收到此错误并知道如何处理吗?

Anyone else getting this error and know how to deal with it?

推荐答案

如果在 XML 中将 android:animateLayoutChanges 设置为 true 并调用 notifyDataSetChanged() 在 Java 代码中 RecyclerView 的适配器上.

This error is caused if in your XML you have android:animateLayoutChanges set to true and you call notifyDataSetChanged() on the RecyclerView's adapter in the Java code.

因此，请避免将 android:animateLayoutChanges 与 RecyclerViews 一起使用.

So, just avoid using android:animateLayoutChanges with RecyclerViews.
