相关疑难解决方法(0)

我有一个ListView,里面有一些可聚焦的组件(主要是EditTexts).是的,我知道这不是完全推荐的,但总的来说,几乎所有东西都工作正常,重点放在必须去的地方(我需要进行一些调整代码).无论如何,我的问题是,当用手指滚动列表然后在显示IME键盘时突然使用轨迹球时,存在一种奇怪的竞争条件.有些东西必须超出范围并得到回收,此时该offsetRectBetweenParentAndChild()方法必须启动并抛出IllegalArgumentException.

问题是这个异常被抛出我可以插入try/catch的任何块之外(据我所知).所以这个问题有两个有效的解决方案:

1. 有人知道为什么抛出这个异常以及如何阻止它发生
2. 有人知道如何在某个地方放置一个try/catch块,至少让我的应用程序存活下来.据我所知,问题是焦点,所以它绝对不应该杀死我的应用程序(这是它正在做的).我尝试重写了ViewGroup这些方法,但这两种offset*方法被标记为final.

版图设计:

HorizontalScrollView-parent, holding RV[
    RecyclerView=>(GridLayoutManager) (orientation verticle)]

哪个基本上会做双向滚动.此UI适用于电视.此网格中的焦点行将显示额外的细节,而其他行则不会.所以,每当有从一行的焦点变化到另一个onFocusChange我修改dataset的Adapter,并调用notifyItemRangeChanged().

当行长度超过屏幕的垂直长度,即垂直可滚动时,这可以正常工作.发生崩溃就像是行数较少(如4).

当我尝试使用 Intent 或 Finish() 返回此视图时会发生此错误；另一个视图中的方法。当我使用后退按钮时，这不是问题。

所以我不知道为什么我有这个错误。谢谢你的帮助。
