暂停后如何保存View的状态？

Question

When my app completes some async tasks, it notifies UI about it.

For example:

1. user clicks on "Do work" button inside of my application -> async work started
2. and switches to another app -> state is saved
3. then "work" inside my app is finished and View-s updated -> async work finished (note that my activity is paused)
4. User rotates the phone and then navigating back to my app
5. problem: state is restored and View's state updated in 3 step is gone while work was finished!

How to deal with such cases? Is there any way to save settings after app is paused?

Answer 1

考虑使用MvpQueuingBasePresenter或Model-View-Intent，它可以更好地处理与生命周期相关的事情。

Answer 2

I think you should update the state of the view in onResume method from that activity.
