ListView 控件可使用四种不同视图显示项目。通过此控件，可将项目组成带有或不带有列标头的列，并显示伴随的图标和文本。
可使用 ListView 控件将称作 ListItem 对象的列表条目组织成下列四种不同的视图之一：1.大（标准）图标2.小图标3.列表4.报表 View 属性决定在列表中控件使用何种视图显示项目。
还可用 LabelWrap 属性控制列表中与项目关联的标签是否可换行显示。另外，还可管理列表中项目的排序方法和选定项目的外观。
相信有很人做的项目估计都用的到这个。就是ListView的下拉刷新上拉加载还有就是列的横向滚动;
PS：横向滚动带表头与固定列(相信蛮多人都有这样的需求吧？就是在ListView上支持很多列,然而设备屏幕宽度有限)
PS：这是我个人在网上找的两个示例demo结合而成的一个示例demo,还可以继续拓展,后续有时间就会更新,大家互相学习

接下来就是晒一下项目列表图
java代码
布局文件xml
效果图：
横向滚动过的图和下拉刷新,由于不会弄动态图只能这样了
下拉刷新
刷新中
上拉加载
接下来就是上代码了,请往下看
