Android中Context类情况说明。
作者其他创作
大纲/内容
是什么？
官方术语
<span style="font-size: 17px;">Interface to global information about an application environment</span>
通俗说明
如果一个Android APP是一部电影，那四大组件就是四个主演，其余组件就是配角，而Context就是摄像机。一部电影所有的场景录制离不开摄像机，一个APP中所有的交互离不开Context
类结构情况
Application、Service、Activity都是Context的子类
怎么用？
