Android Q access非SDK接口-Landroid/widget/AbsListView-&燃气轮机；mSelectorPosition:I（greylist-max-p，反射，拒绝）

需要一个帮助，我们可以在Android Q中使用旧API

我面临着这个问题

一切正常，直到下午

如何启用对非SDK接口的访问

如何启用对非SDK接口的访问

这是不可能的

修复库，使其不尝试使用此隐藏字段。因为这个库已经五年没有更新了，所以最初的开发人员不太可能解决这个问题

或者，找到一个替换库并使用它

---

或者，创建您自己的替换UI。

您的代码没有问题，但您使用的是一个未更新的Android 10，其目标sdk KitKat（API 19）非常陈旧。您需要使用更更新的库替换此库，并且基于Android p上的

RecyclerView

，此库不起作用。您只需使用android

ExpandableListView

。这将是一对一可替换的

---

您可以尝试使用FloatingGroupExpandableListView存储库中的示例项目，只需使用

ExpandableListView

代替

com.diegocarloslima.fgelv.lib.FloatingGroupExpandableListView

。它应该可以工作。

现在，如果我们可以使用proguard规则，并且可以在android 10上访问，那么将非常感谢您的更新，那么是否有其他AbsListview的替代方案。我需要替换AbsListview吗？@Mahesh:您不能替换

AbsListview

。这是一个框架类。你不需要尝试通过反射来访问它的私有字段。如果可能的话，你能给我一些提示或例子，说明在什么地方这样做了，或者类似的，这样我可以尽快修复它。这在我的生产应用程序上造成了一个大问题。
