indexoutofboundsexception它是关于ArrayList的？是的，它是关于代码中的
ArrayList的。在某个时刻，您的数据适配器的大小为3
，您正试图访问索引3
处的元素，这会引发IndexOutOfBoundsException
。请始终记住，如果ArrayList
的大小为x
，则只能访问索引x-1
例如：如果大小为4
，则
列表。获取（3）
-是允许的
列表。获取（4）
-是不允许的是的，它是关于代码中的数组列表。在某个时刻，您的数据适配器的大小为3

。请始终记住，如果ArrayList

例如：如果大小为4

列表。获取（3）
-是允许的
list.get（4）
-不允许调用dataAdapter.remove（）
，而不更改微调器中选定的索引。然后在SaveData（）
函数中调用spinner1.getSelectedItem（）
，从而产生IndexOutOfBoundsException
解决方案是什么？将所选索引设置为从适配器中删除项目后仍然存在的索引。您正在调用dataAdapter.remove（）
，而不更改微调器中的所选索引。然后在SaveData（）
函数中调用spinner1.getSelectedItem（）
，从而产生IndexOutOfBoundsException
解决方案是什么？将所选索引设置为从适配器中删除项目后仍然存在的索引。如果要获得微调器所选项目位置，只需使用
spinner.getSelectedItemPosition() which gives integer value..
为什么要使用
String myData = toList.getSelectedItem().toString();
int position = dataAdapter.getPosition(myData); // I think the problem is here
您可以直接初始化
int position = toList.getSelectedItemPosition();

是的，我错了，现在我在删除项之前放置了SaveData（）
方法。而且有效。谢谢，我错了，现在我把SaveData（）。而且有效。谢谢
