Android中的偏好和共享偏好之间的差异 [英] Difference between preference and shared preference in Android

问题描述

Android中的偏好和共享偏好的概念对我来说很混乱。有什么区别？

解决方案

：这些用于在XML文件中存储值。 Android会为您创建，维护和删除这些文件。它们未加密，很容易当用户植根他/她的手机时改变了（很适合开发）。请勿将这些信息用于敏感信息。上面提到的首选项使用共享首选项作为底层系统。

The concept of preferences and shared preferences in Android are mixed up for me. What is the difference?

解决方案

Preferences: The user interface part of the settings. It contains different classes which allow to composes Settings screens from code or XML. They can look like this:

Shared Preferences: These are used to store values in XML files. These files are created, maintained and deleted by Android for you. They are not encrypted and can easily be changed when the user has rooted his/her phone (nice for development). Don't use these for sensitive information. The above mentioned Preferences use Shared Preferences as the underlying system.
