完成旧活动并开始新活动，反之亦然 [英] Finish old activity and start a new one or vice versa

问题描述

我知道，我用两个代码片段得到了相同的结果

I know, that I get the same result with both code snippets

finish();
startActivity(newActivity);

和

startActivity(newActivity);
finish();

我想知道你的意见，如果他们之间有很大的不同.这个比那个好吗?如果是，为什么?

I'd like to know your opinion, if there is a big difference between them. Is one better than the other? If so, why?

推荐答案

当您执行 startActivity() 时，所做的只是将您的意图发布到事件队列中.活动的实际启动在不久的将来异步发生.所以我看不出两者有什么大的区别.

When you do startActivity(), all that does is post your intent in a queue of events. The actual starting of the activity happens asynchronously in the near future. So I don't see a big difference between the two.
