1、android.preference.Preference
Represents the basic Preference UI building block displayed by a PreferenceActivity in the form of a ListView. This class provides the View to be displayed in the activity and associates with a SharedPreferences to store/retrieve the preference data.
When specifying a preference hierarchy in XML, each element can point to a subclass of Preference, similar to the view hierarchy and layouts.
This class contains a key that will be used as the key into the SharedPreferences. It is up to the subclass to decide how to store the value.
通过PreferenceActivity以ListView的形式显示,这个类提供了在activity中显示View的方法,同时使用SharedPrederence对象来存储/检索preference data.
在实际的xml布局文件中,可以使用Preference的具体子类。
这个类包含了在SharedPreference中作为键值的key。一般由子类来决定如何存储值。

本文详细介绍了Android中的Preference类,它是PreferenceActivity的基本UI构建块,并通过ListView形式展示。Preference类负责提供在Activity中显示的View,并使用SharedPreferences来存储和检索偏好设置数据。在XML布局文件中,可以通过指定Preference的不同子类来实现具体的偏好设置。
