这与如何在android中的列表视图上永久保存列表项 [ ^ ]。你是什​​么意思这段代码不起作用？



正如我昨天解释的那样你需要花时间调试你的调试器有关代码运行时出现的情况以及出错的信息。没有mor信息就无法提供帮助。



只是转储代码并期望其他人为你调试它是没有用的。

This looks like the same issue as How to save list items permanently on list view in android[^]. And what do you mean by "this code does not work"?

As I explained yesterday you need to spend time with your debugger collecting information about what happens when your code runs and where things go wrong. Without mor information it is impossible to offer help.

It is no use just dumping your code and expecting other people to debug it for you.
