设置活动应使用哪个：首选项api或sharedpreferences？

Question

I have a settings activity for users in my application. I manually add the changes to a sharedpreferences file ( simple delete , edit , add operations ). It works fine but just now i heard of preferences activity . Should i use it instead?

Answer 1

PreferenceActivity and Fragment provide some advantages:

• Declare your UI through XML, where you can put preferences in categories, this makes your settings look and feel consistent with the system settings.
• Declaring preferences through xml associate each preference with a key and/or a default value, this saves you from writing the logic that handles such cases.

In the end you can achieve the same results with both approaches, but I recommend using the Preferences Activity/Fragment for the consistency with the system and avoiding boilerplate code or bugs that may appear from implementing the preferences yourself.
