项目描述：
最近做项目，遇到一个问题，就是要求ListView既要有表头，点击表头从能够对特定的列进行排序，并且要求固定第一列，右边的其他列不固定，能够向左滑动的时候，收缩到左侧，向右滑动的时候，显示已经收缩的列，总之就是满足一个需求，一个表里面有很多个列的时候，单个屏幕显示不完所有的列，因此，就做一个可收缩的列表，用于在一个控件里面显示完表中所有的字段。
小的我参考了网上的代码，名字为demoHListView（大家可以到网上搜索下载，或者在我共享的代码中去下载），是用观察者模式来实现的效果，但是我对这个示例做了改造，因为它并不可以支持分页加载以及点击列头按当前列数据排序,还是直接把我的代码贴出来。
注意：
1、ListView是用的网上封装好的支持上下拉分页加载的控件（PullToRefreshListView）。这里边儿要注意把封装控件中的ListView对象声明为成员变量，然后通过get()方法返回出来。
改造部分的代码如下：

页面布局部分的代码：
注意布局这部分的代码很关键，要把示例中的最外层控件移除才可以保证点击列头的时候，每一页可以点击，不会抢占列头里层控件的焦点，这也才能保证点击列头排序功能的实现。
