将View 转化程数的过程 http://www.cnblogs.com/xiaoweiz/p/3787844.html
这个是下面的错误
java.lang.RuntimeException:Unable to start activity ComponentInfo{com.sensu.automall/com.sensu.automall.activity_main.MainActivity}: java.lang.RuntimeException: Unable to start activity ComponentInfo{com.sensu.automall/com.sensu.automall.activity_main.AutoMallMainActivity}: java.lang.IllegalArgumentException: Wrong state class, expecting View State but received class android.widget.AbsListView$SavedState instead. This usually happens when two views of different type have the same id in the same hierarchy. This view's id is id/pull_refresh_list. Make sure other views do not use the same id.
