我把整个功能写成了一个类，在需要用的时候只需要new出这个类就可以直接使用了
该类目前的所有方法:
Java代码
  1. /**初始化带标题ListView.*/
  2. CListView(Context,String[],List<String[]>)
  3. /**整体有改变时，刷新显示.*/
  4. definedSetChanged()
  5. /**设置选中时的监听器.*/
  6. setOnItemClickListener(OnItemClickListener)
  7. /**设置行背景颜色,多个颜色可以作为间隔色.*/
  8. setItemBackgroundColor(int...)
  9. /**数据总数.*/
  10. getCount()
  11. /**当前选中数据.*/
  12. getItem(int)
  13. /**设置当前选中位置.*/
  14. setSelectedPosition(int)
  15. /**当前选中位置.*/
  16. getSelectedPosition()
  17. /**设置被选中时的背景色.*/
  18. setSelectedBackgroundColor(int)
  19. /**设置标题背景色.*/
  20. setTitleBackgroundColor(int)
  21. /**设置标题文字颜色.*/
  22. setTitleTextColor(int)
  23. /**设置内容文字颜色.*/
  24. setContentTextColor(int)
  25. /**设置标题字体大小.*/
  26. setTitleTextSize(float)
  27. /**设置内容字体大小.*/
  28. setContentTextSize(float)
  29. /**设定哪列自动列宽从0开始计算.*/
  30. setAutoColumnWidth(int)
