问题描述

java.util中像HashMap的?

What is the difference between Bundle Vs java.util collections like HashMap?

推荐答案

一个区别,我可以很容易地看到的是,一个包可以让你把整型,布尔型,等等,把它当一个HashMap似乎要求你将它们转换到/从对象

One difference I can see easily is that a Bundle allows you to put int, boolean, etc., into it while a HashMap seems to require you to convert them to/from objects.

有一个更重要的区别是,一个包,每个对象包含的parcelable。这使得束被用作服务参数,也可以附连到意图/传递到活动

A more important difference is that with a Bundle, every object it contains is parcelable. This allows Bundles to be used as service parameters and to be attached to intents / passed into activities.
