android - 如何从片段中调用 PreferenceFragment

Question

我有一个扩展 PreferenceFragment 的类 profileFragment。我有另一个扩展片段的 myFragment 类。如何在 Fragment 类中调用 PreferenceFragment 类？这很重要，因为我使用基于片段的滑动菜单，因此我无法从片段中的其他任何地方调用 PreferenceFragment

I don't have enough information to give you a full answer, as it seems to me if you have a sliding menu based on fragments, you could just add a "Settings" option in your sliding menu, and navigate to it using the FragmentManager from the Activity.

A few things you may want to consider (I'd personally recommend looking at #3):

1. As I mentioned above, having a separate "Settings" Navigation item in your sliding menu.
2. Making a call from your normal fragment to your Activity to navigate to the PreferenceFragment. You'd want to read up on Fragment Communicationto learn how you should talk to your Activity though.
3. You might not even need a PreferenceFragment. It sounds like maybe a better use case for what you are trying to do might be a DialogPreference.
4. You could also look into using Child Fragments ( getChildFragmentManager() ), and having your PreferenceFragment be a child fragment of your other fragment. This is getting a bit complicated though.
