上回再写了《Android中使用ListView绘制自定义表格》后,很多人留言代码不全和没有数据样例。但因为项目原因,没法把源码全部贴上来。近两天,抽空简化了一下,做了一个例子。
效果图如
一、功能:
1、支持列合并
2、考虑了界面刷新优化
3、预留部分接口
4、支持左右滚动
1、枚举类:CellTypeEnum
package csdn.danielinbiti.custometableview.item; public enum CellTypeEnum { STRING //字符 ,DIGIT //数字 ,LABEL //标签 }该类定义了表格支持的样式,可以根据需要扩充,扩充了新类型,注意同时修改CustomeTableItem中新类型样式的创建方式
2、核心代码CustomeTableItem,该类对应ListView的一行item。类支持列合并,没有实现行合并(行合并样式控制上会比较复杂些,如有需要自己改写吧)
rowtype:该值主要表示表格中不同行的样式,如果合并的列都一样的行,则可以复用,不需要再创建了。
