        <attr name="ptrScrollingWhileRefreshingEnabled" format="reference|boolean" />

        <!--
                Whether PullToRefreshListView has it's extras enabled. This allows the user to be

                Header and/or Footer Views to the ListView.
        -->
        <attr name="ptrListViewExtrasEnabled" format="reference|boolean" />

        <!--

</resources>

1.1、ptr:ptrMode
disabled       不刷新
pullFromStart  下拉刷新
pullFromEnd    上拉加载
both           上拉和下拉

2、ptr:ptrAnimationStyle
参考：https://github.com/chrisbanes/Android-PullToRefresh/wiki/Customisation
控制下拉刷新—>松开刷新时的 progress的变化
rotate 旋转，类似于圆形的progress那种
flip  最常见的那种，箭头翻转一下

3、ptr:ptrDrawable
就是上面提到的那个progress的图片

4、ptr:ptrHeaderBackground
就是header的背景图

一般常用到的也就这四个，其他的用到了 再补充
