android - RecyclerView 在 "scrapped or attached views may not be recycled"时崩溃

Question

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

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

简单来说，我的意思是它与 this page on their website 中的实现相同。 ，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。

还有其他人收到此错误并知道如何处理吗？

Answer 1

如果在您的 XML 中将 android:animateLayoutChanges 设置为 true，并且您在 Java 代码中调用 RecyclerView 的适配器上的 notifyDataSetChanged()，则会导致此错误。

所以，请避免将 android:animateLayoutChanges 与 RecyclerViews 一起使用。
