我什么时候应该实例化Activity类? [英] When am I supposed to instantiate Activity class?

问题描述

我看到可以通过new关键字实例化Activity.

I see that it is allowed to instantiate Activity via new keyword.

new MainActivity();

这样做时，我立即可以访问其所有字段，事件等.

When I do that, I immediately get access to all its fields, events, etc.

那么，我何时应该以这种方式实例化某些Activity类?我的意思是在哪种情况下.

So, when should I ever need to instantiate some Activity class in such a way? I mean in which situations.

谢谢.

推荐答案

从不.创建Activity实例应始终由ActivityManager单独处理，具体取决于您发送的Intent项目.

Never. Creating Activity instances should always be handled by the ActivityManager alone based on the Intent items you send.
