使用第三方类XListView，实现ListView的加载刷新，提示

    使用第三方类XListView，实现ListView的加载刷新，提示
    首先 ，file - new - new Module 新建一个Module，名字自定义
    java         workSpace -- project
    android      project -- Module
    在 Module 的 src 目录下有
    1. androidTest
    2. main
    3. test
    在mian 目录下面java 目录下有，新建一个包名，最好是按照路径来命名
    在此目录下引三个类
    XListView
    XListViewFooter
    XListViewHeader
    最后选择file--Progect Structure -- app---dependencies-- "+"
    这里有三个选项
    library dependencies--在线加载，输入加载的网站即可在线加载
    File dependency -- 引进lib 目录下的第三方包
    Module dependency -- 引进Module ,选他，弹出的对话框里有刚刚新建的Module，确认就行了

    使用第三方类XListView，实现ListView的加载刷新，提示
    首先 ，file - new - new Module 新建一个Module，名字自定义
    java         workSpace -- project
    android      project -- Module
    在 Module 的 src 目录下有
    1. androidTest
    2. main
    3. test
    在mian 目录下面java 目录下有，新建一个包名，最好是按照路径来命名
    在此目录下引三个类
    XListView
    XListViewFooter
    XListViewHeader
    最后选择file--Progect Structure -- app---dependencies-- "+"
    这里有三个选项
    library dependencies--在线加载，输入加载的网站即可在线加载
    File dependency -- 引进lib 目录下的第三方包
    Module dependency -- 引进Module ,选他，弹出的对话框里有刚刚新建的Module，确认就行了
