Android在首选项片段中按下后退按钮时会调用什么方法
[英]Android what method is called when back button is pushed in a Preference Fragment
问题描述
I have a preference fragment and it has an option to open another preference fragment that allows the user to select contacts. 
我有一个首选项片段，它有一个选项可以打开另一个首选项片段，允许用户选择联系人。 When I push the back button the values in the first preference fragment don't refresh. 当我按下后退按钮时，第一个首选项片段中的值不会刷新。 What method is invoked when I press the back button? 当我按下返回按钮时，调用什么方法？
