我得到例外，但没有行号来指向我的班级。那么我怎样才能找到异常呢？感谢您的建议

Answer 1

HeaderViewListAdapter.java：164

它显示您在 HeaderViewListAdapter.java 类中的第 164 行有错误。

Answer 2

这里

可能发生的是以下其中之一：

• 将数组传递给适配器，并在显示之前对其进行修改
• 覆盖适配器以返回与数组大小不匹配的 getCount(( 值

Answer 3

在应用程序启动时放置一个断点，例如在 onCreate(( 中，并在调试模式下启动。但是，IndexOutOfBoundsException应该为您提供一些指导，例如，在代码中的何处访问ArrayList对象的值？

Answer 4

java.lang.IndexOutOfBoundsException： 索引无效 1，大小为 1这意味着您的数组大小为 1，你尝试获取数组[1]而不是数组[0]

请发送代码。
