Kotlin：添加到列表视图

Question

我创建了一个列表视图，并用数据填充了它。我在列表中添加了一个点击侦听器，它将使列表减少2个项目并显示新列表。

但是，当我显示新列表时，我得到了ArrayIndexOutOfBoundsException。

要纠正此问题，我建立了一个if查询，询问是否已经到达列表的末尾，在这种情况下，返回模板行。有没有一种方法，我只是得到一条线而不是模板线？我认为现在插入显示的空模板行是错误的。如果我展开它们，则列表是否显示所有项目也将是一个问题。

java.lang.ArrayIndexOutOfBoundsException: length=3; index=3
    at com.example.evpic.ui.main.RightFragment$MyAdapter.getView(RightFragment.kt:33)
    at android.widget.AbsListView.obtainView(AbsListView.java:3271)
