Android：onRetainNonConfigurationInstance（）已弃用？

[英]Android: onRetainNonConfigurationInstance() deprecated?

原文 2013-11-14 00:40:18 5 1 android/ android-fragments/ android-activity/ deprecated

Inside my Activity I am instantiating an object which is responsible to query, process and store the data needed by the fragments. 在我的Activity里面我实例化一个对象，它负责查询，处理和存储片段所需的数据。 I was about to use onRetainNonConfigurationInstance() in order to retain the object after configuration changes, but I just realized the method has been deprecated. 我准备使用onRetainNonConfigurationInstance()以便在配置更改后保留对象，但我刚刚意识到该方法已被弃用。

I can see that the new recommended way is to use Fragment's setRetainInstance() , but it doesn't look like it's what I need, because my object doesn't deal with just 1 fragment. 我可以看到新推荐的方法是使用Fragment的setRetainInstance() ，但它看起来不像我需要的，因为我的对象不处理只有1个片段。

Do you have any suggestions? 你有什么建议吗？

because my object doesn't deal with just 1 fragment 因为我的对象只处理1个片段

No, but your fragment can deal with whatever the object is. 不，但你的片段可以处理任何对象。

onRetainNonConfigurationInstance() requires you to package everything into one object. onRetainNonConfigurationInstance()要求您将所有内容打包到一个对象中。 Consider the retained fragment strategy to be requiring that this "one object" be a fragment, on which you call setRetainInstance() . 考虑保留的片段策略要求这个“一个对象”是一个片段，在其上调用setRetainInstance() 。 Anything you could do with onRetainNonConfigurationInstance() should be doable with a retained fragment. 你可以用onRetainNonConfigurationInstance()做的任何事都应该对保留的片段onRetainNonConfigurationInstance() 。
