ListView实现带标题栏效果（附源码）

我的实现思路是重写一个LinearLayout，在里面放一个标题栏，再在下面放一个ListView存放数据 ，  目前实现了文字列宽自动适应， 自动排版内容等功能 。

 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:
/** 初始化带标题ListView. */
CListView(Context, String[], List<String[]>)
/** 整体有改变时，刷新显示. */
definedSetChanged()
/** 设置选中时的监听器. */
setOnItemClickListener(OnItemClickListener)
/** 设置行背景颜色, 多个颜色可以作为间隔色. */
setItemBackgroundColor(int...)
/** 数据总数. */
getCount()
/** 当前选中数据. */
getItem(int)
/** 设置当前选中位置. */
setSelectedPosition(int)
/** 当前选中位置. */
getSelectedPosition()
/** 设置被选中时的背景色. */
setSelectedBackgroundColor(int)
/** 设置标题背景色. */
setTitleBackgroundColor(int)
/** 设置标题文字颜色. */
setTitleTextColor(int)
/** 设置内容文字颜色. */
setContentTextColor(int)
/** 设置标题字体大小. */
setTitleTextSize(float)
/** 设置内容字体大小. */
setContentTextSize(float)
/** 设定哪列自动列宽 从0开始计算. */
setAutoColumnWidth(int)

这是我的代码，希望各位如果有什么好的建议都提出来，或者大家对其有修改也希望发给我一份：
