小弟最近自學於Android上開發,常常遇到需要傳遞Context類別參數傳遞,
對於Context類別敘述原文如下 :
Class Overview
Interface to global information about an application environment.
This is an abstract class whose implementation is provided by
the Android system. It allows access to application-specific
resources and classes, as well as up-calls for application-level
operations such as launching activities, broadcasting and
receiving intents, etc
依小弟認知,他是指這類別靠Android系統實現,去允許存取特殊應用的資源跟類別,
要求應用層級操作，如啟動activities、broadcasting和接收intents等,但是
還是有點難以理解,是否有人可以白話一點解釋Context的作用?
另外,傳遞Context context這種參數時(如PendingIntent.getActivity
(Context context, int requestCode, Intent intent, int flags)
...等等)為什麼可以用this傳遞?
謝謝大家~~
