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

七、/res/xml/setting.xml
ListPreference中的属性
android:entries="@array/entries_repeat" 显示给用户的内容
android:entryValues="@array/entriesvalue_repeat" 实际传给java代码的值
在/res/values/array.xml中定义
