// 添加XListView的上拉和下拉刷新监听器lv_main_reference.setPullLoadEnable(true);lv_main_reference.setPullRefreshEnable(true);lv_main_reference.setXListViewListener(this);


刷新的时候调用

SimpleDataExample.setFormat("dddddddddddd", getApplicationContext());
         SimpleDataExample.getFormat("dddddddddddd", getApplicationContext(), lv_main_reference);



XListView
