Android具有多选功能的滚动抽签范例
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。

注意：本项目是基于android studio开发的，eclipse可能无法直接使用。
本项目是一个简单的基于安卓的记事本项目源码，添加或删除数据的时候会出现显示bug（实际数据不会受到影响），bug体现在添加或删除一条数据以后会在listview里面会展示复制一遍操作后的数据。而不会清除原有的列表文本。新手朋友可以拿这个项目来试试手感，顺便看看能不能独立解决这个问题。
本项目涉及的知识点有：
1、SQLite的基本使用，增删查改
2、listview，adapeter的基本使用
3、activity生命周期
4、intent、bundle传递参数
5、AlertDialog的基本使用(Note: this project is based on the development of studio eclipse, Android may not be able to directly use.
This project is a simple Notepad program source code based on Android, add or delete data will appear when the display bug (actual data will not be affected), bug reflected in add or remove a data will be in inside the listview will show copy again after the operation data. And will not clear the original list of text. Novice friends can take this project to try to feel, by the way to solve this problem can not be solved independently.
The knowledge points involved in this project are:
1, the basic use of SQLite, CRUD
2, listview, the basic use of adapeter
3, activity life cycle
4, intent, bundle transfer parameters
5, the basic use of AlertDialog)
