Android开发ListView中下拉刷新上拉加载及带列的横向滚动实现方法

2019/7/7 19:42:43

本文主要是介绍Android开发ListView中下拉刷新上拉加载及带列的横向滚动实现方法,对大家解决编程问题具有一定的参考价值,需要的程序猿们随着小编来一起学习吧!

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

@Override

@Override
protected void onScrollChanged(int l, int t, int oldl, int oldt) {
// 当当前的CHSCrollView被触摸时,滑动其它
