Java Android Listview autoscroll使项目不可见

我有进度项目的进度列表视图。每当项目完成时，我都勾选它

该进度项目分为几个阶段。每个阶段都可以包含步骤。完成所有步骤并用复选标记后，代码将整个阶段标记为完成

最后，我所做的只是呈现一个阶段的listview，并为每个阶段动态添加另一个listview。我最终得到了包含更多listview的listview

这个很好用，我没有任何问题

我的老板让我创建一个自动滚动程序，它将按照完成的步骤进行操作。我实现了这一点，并且很高兴看到它能够工作

问题：我很高兴它只在达到一半多一点的时候起作用。然后突然间，我的心碎了。当我触摸列表时，列表返回顶部，所有项目都可见

你知道什么会导致这种行为吗

这方面的代码相当大，因此我将只分享我认为需要的部分

如果（listviewBottom您的适配器代码在我的手机中不起作用。只显示部分子列表。此外，我认为您的要求更容易通过ExpandableListView实现。因此，我按照您的数据结构创建了以下使用ExpandableListView的演示代码。您可以启动一个新项目并尝试
