我有一个 listView，它是通过 SQL 数据库中的自定义游标加载的。它用于从不同活动的主列表中删除项目。每一行都有一个复选框，当用户单击“删除行”的删除按钮时，该行的“一行”复选框出现了一个隐藏的删除按钮。
在我运行 2.3.5 的 HTC Desire HD 上，它运行良好，我没有任何问题，但是在我朋友的手机、Galaxy Note 和 S3 上，运行 Ice cream sandwhich 会发生错误。在运行 icecream sandwhich 的手机上，如果他们选中每一行的复选框，然后单击最后一行的删除按钮，则应用程序会因arrayIndexOutOfBounds错误而崩溃。此块中出现错误
if ( isChecked )
{
// Make deleteButton appear
RelativeLayout ll = (RelativeLayout) buttonView.getParent();
deleteButton = (Button) ll.findViewById(R.id.deleteButton);
checked[position] = 1;
deleteButton.setVisibility(0);
}
在这一行：checked[position] = 1;在第 98 行。
任何人都可以解释为什么会这样吗？
错误日志在下面，我的代码在下面。
