有人知道怎么解决吗？

Answer 1

从您的崩溃日志中，这里是相关行:

android.widget.AbsListView$RecycleBin.addScrapView(AbsListView.java:6588)

if (mViewTypeCount == 1) {
    mCurrentScrap.add(scrap);
} else {
    mScrapViews[viewType].add(scrap);
}

本质上，当您将 ListView 项滚动到屏幕之外并且回收器尝试回收它时，就会发生这种情况。此 View 的 View 类型(由 android.widget.Adapter#getItemViewType(int) 返回)抛出 java.lang.ArrayIndexOutOfBoundsException: length=2;索引=2。

参见android.widget.Adapter#getItemViewType(int) :

Note: Integers must be in the range 0 to getViewTypeCount() - 1.

我也遇到了同样的问题。检查 getItemViewType(int) 的重写方法，并确保返回连续的零索引号。由于您的 getViewTypeCount() 方法返回 2，因此项目类型常量必须为 0 和 1。
