我有一个 4 值的微调器

在此处输入图像描述

}

当我在微调器中选择最后一项“Petak 4”并使用按钮删除该项目时，

此代码在 onClick 按钮方法内工作，带有开关盒。

但是当我将代码放入 onActivityResult 时，应用程序被强制关闭

String myData = toList.getSelectedItem().toString();
              int position = dataAdapter.getPosition(myData);


               if(position >= 0){
                dataAdapter.remove(myData);
                dataAdapter.notifyDataSetChanged();
               }
               else {
                Toast.makeText(getBaseContext(), myData + " not in Spinner", Toast.LENGTH_LONG).show();
               }



            View b = findViewById(R.id.btnPupukQuit);
            b.setVisibility(View.GONE);
            onBackPressed();
            onAttachedToWindow();

这是我的日志猫

如何修复错误indexoutofboundsexception？

它是关于 ArrayList 的吗？

您正在调用dataAdapter.remove()而不更改微调器中选定的索引。然后spinner1.getSelectedItem()在您的SaveData()函数中调用，导致IndexOutOfBoundsException.

解决方案？将所选索引设置为从适配器中删除项目后仍然存在的内容。

如果您想获得 Spinner 选择的项目位置，那么只需使用

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

可以直接初始化

int position = toList.getSelectedItemPosition();

是的，它ArrayList与您的代码中的一个有关。在某些时候，您dataAdapter拥有 size 3，并且您试图访问 index 处的元素3，这是 throwing IndexOutOfBoundsException。永远记住，如果你的大小ArrayList是x，你只能访问到 index x-1。

例如：如果大小为4，则

list.get(3)-允许

list.get(4)-不允许
