Android具有多选功能的滚动抽签范例

代码说明：

Android具有多选功能的滚动抽签范例，抽奖的候选名单可以从列表中选择，支持多选，然后进行抽签。抽签的候选名单本例中使用了数组，定义在String[] areas中，形如String[] areas = new String[]{"蔡瑞", "徐永浩", "范金端", "王源", "李英明", "刘宇阳","聂明炎","张启震","杨志爽","马玉炎","邢全伟","詹旭琛","刘津旭","陈琳","陈凯","谢冲","王辰","舒震","刘坚强","沈依铭","欧阳知雨","王晨","路少雯","王蕾","郭毛","宋蜜","刘琛","任梦萤","徐瑶","叶乔羽","董乐","孟燦"};，然后定义了多选列表中的数据、抽签等多个子函数来完成功能，代码还是比较简单的。
