Question

我编辑这张票。

我仍然看到那些在生产中发生的崩溃。很少，但我想了解问题所在。

我的跟踪中没有数据可以指示它在我的代码中崩溃的位置。

我应该在基于堆栈跟踪的代码中查找什么？

我搜索了java.lang.IllegalStateException android.widget.ListView.layoutChildren这个术语，我发现大多数注释都与notifyDataSetChanged相关，其中doc说：

通知附加的观察者基础数据已被更改，反映数据集的任何视图都应自行刷新。

我正在使用大约10个列表视图。我动态添加项目，它们永远不会改变。如果他们这样做，我清除列表并从头开始重建。

这是堆栈跟踪：
