安卓：什么是捆绑VS java.util中的集合类似的HashMap的区别 [英] Android: what is the difference between Bundle Vs java.util collections like HashMap

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.
