我在我的应用上学习holoeverywhere库（https://github.com/Prototik/HoloEverywhere），但在与PullToRefresh库（https://github.com/johannilsson/android-pulltorefresh）结合使用时遇到问题，如何解决？
问题 无法启动活动ComponentInfo {com.droidersuin.project / com.droidersuin.project.app.ContentActivity}：java.lang.ClassCastException：com.markupartist.android.widget.PullToRefreshListView无法强制转换为org.holoeverywhere.widget .ListView
这个logcat
