Android ListView实现Table行列效果

先来看运行效果:

就两个类，放上去运行就可以看到效果。

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)
