Fragments 中的 commit() 和 commitAllowingStateLoss() 有什么区别 [英] What is the difference between commit() and commitAllowingStateLoss() in Fragments

问题描述

我在我的项目中使用了 commit 方法，该方法使用片段构建它.

I was using the commit method in my project that built it with fragments.

无论如何，有时我会收到 IllegalStateException: Can not perform this action after onSaveInstanceState 错误，我找不到任何好的解决方案，但只有这个方法 commitAllowingStateLoss().我将提交函数更改为 commitAllowingStateLoss() 但没有使用它很长时间来测试所以这个函数可以帮助我吗?主要问题是，commit() 和 commitAllowingStateLoss() 之间有什么区别?

Anyway, sometimes I was getting IllegalStateException: Can not perform this action after onSaveInstanceState error and I couldn't find any good solution about it but just this method commitAllowingStateLoss(). I changed commit function to commitAllowingStateLoss() but didn't use it long time to test so may this function help me? And the main question, what is the difference between commit() and commitAllowingStateLoss()?

推荐答案

commit() 和 commitAllowingStateLoss() 之间只有一个区别:后者没有如果发生状态丢失，则抛出异常.除此之外，它们具有相同的行为.

There is only one difference between commit() and commitAllowingStateLoss(): the latter doesn't throw an exception if state loss occurs. Other than that, they have identical behavior.
