ArrayIndexOutOfBounds使用ListAdapter时的异常

我正在使用一个.我不会动态更改任何内容（视图计数，视图类型，启用/禁用，我阅读了其他帖子，但他们从代码中更改了一些内容）。我必须执行以下操作来触发异常。向下滚动到列表底部，然后再次向上滚动。在滚动动画开始时，我得到了这个例外。ListAdapterListView

我从这里将源代码附加到Android 2.3.3库。我没有发现堆栈跟踪没有向我显示的任何其他内容。众所周知，回收视图。有一个集合可以保存这些回收视图。当一个视图消失时，它被添加到那里（我认为）。这发生在某处，它给了我一个例外，即某些东西超出了界限。我丝毫不知道是什么。但是我没有耐心调试另外1000行代码，所以我想我现在将使用ScrollView。ListViewat android.widget.AbsListView$RecycleBin.addScrapView(AbsListView.java:4540)

似乎是这样一行：（AbsListView.class：4540 mScrapViews是类型。它是类型列表的数组。我可以尝试观看和变量，但它说.可能太笨了，无法评估。mScrapViews[viewType].add(scrap);private ArrayList<View>[] mScrapViews;ViewviewTypescraperrors_during_evaluation
