[安卓初学者实验]AdapterView与Notification练习

1．  实验目的

 

理解掌握Android界面的AdapterView、ScrollView和Notification的使用

 

2．  实验工具

 

计算机，安装Eclipse、JDK、Android SDK、Genymotion等安卓开发环境

 

3．  实验题目

 

1)    以d) BaseAdapter实现以全国23省、4直辖市、5自治区和2特别行政区为列表项的ListView，并加上垂直滚动条。

2)     当点击列表项时，会在状态栏显示一条通知。通知要求具有以下属性：自动消失、通知提示信息、通知图标、标题、内容（为该列表项所显示省份名称以及对应的省会城市，如“您好！浙江省的省会是杭州市！”）、时间、自定义声音和振动。
