XListView 下拉刷新上拉分页加载更多

Xlistview 项目主要是三部分：XlistView,XListViewHeader,XListViewFooter，分别是XListView主体、Header、Footer的实现。Header是通过设置height，Footer是通过设置BottomMargin来模拟拉伸效果。  
实现IXListViewListener接口中的onRefresh()和onLoadMore()方法。每个方法中还需要调用onLoad()方法，关闭刷新和加载。  
使用方法：  
1.获取XListView控件。  
2.上拉刷新setPullLoadEnable(true)。  
3.添加数据，适配器。  
4.给xListView设置监听setXListViewListener(this)。  
5.实现onRefresh()和onLoadMore()方法。  
6.调用onLoad()关闭刷新和加载。

7.layout中必须有header.xml和footer.xml。页面中加入XListView控件。
