I have used the code of RecyclingPagerAdapter from android-demo/src/com/jakewharton/salvage/RecyclingPagerAdapter.java and RecyleBin from android-demo/src/com/jakewharton/salvage/RecycleBin.java but when I try to see the last page from first page before all the pages have been cycled through the app crashes.

在使用下拉刷新及滚动到底部加载更多的ListView的时候，项目中只能包括一个包，不能在项目包含多个包的时候使用，否则会提示：

listViewAttr:isAutoLoadOnBottom="true"
listViewAttr:isDropDownStyle="true"
listViewAttr:isOnBottomStyle="true"

这些属性不存在。
