• Android PreferenceActivity


    一、目标

    JumpToPreferenceActivity.java跳转到MyPreferenceActivity.java.

    MyPreferenceActivity.java是应用设置Activity.

    因为要和另一个项目关联,所以用了Intent,这里Intent纯粹鸡肋,关键是PreferenceActivity的使用

    二、工程文件结构

    JumpToPreferenceActivity.java引用main.xml;

    MyPreferenceActivity.java引用setting.xml;

    setting.xml中的ListPreference引用/res/values/array.xml中的string-array
