Android：如何在活动之间传递ArrayList ？(Android: How to pass ArrayList between Activities?)

我如何将Object：ArrayList从一个Activity传递到另一个？

似乎意图不能容纳除ArrayList外的自定义内容。

作为一种破解，我使用了一个静态成员：

staticResultList = new ArrayList<SingleExamResult>(m_examResults);

并通过以下方式获取以下活动：

m_examResults = DoExam.staticResultList;

这显然不是正确的方式，任何“常见”方法？ 非常感谢！

How can I pass a Object: ArrayList from one Activity to another?

Seems that intent cannot hold custom ones except ArrayList.

As a kind of hack, I use a static member:

staticResultList = new ArrayList<SingleExamResult>(m_examResults);

and Get it in the following Activity by:

m_examResults = DoExam.staticResultList;

It's not the correct way obviously, any 'common' approaches? Thanks a lot!

如果你想避免使用静态成员破解，你的自定义类SingleExamResult必须实现Parcelable接口：

If you want to avoid using the static member hack, your custom class, SingleExamResult, must implement the Parcelable interface:
