摘要
随着城市人口的急剧膨胀导致交通超载负荷,城市地铁的建设极大的缓解了城市交通问题,然而由于众多出入口,往往导致人们出行的困扰,本文以Android为开发平台,以区域电子地图为基础开发了地铁出口导航系统,实现了地铁站各站点出口及周边道路、公交信息等的查询,并通过集成SQLite及Google Map实现数据库管理及地图服务应用。首先介绍了android智能操作系统的基本情况,然后通过分析软件运用的各项技术展现了android平台的强大开放性和兼容性,在引入这些类库的同时又对Android通用框架下应用软件的开发进行了总结,最后以上海南站作为应用背景,通过实例可视化地展示了系统应用的实用性、时效性,为人们的方便快捷出行提供了辅助决策支持。
Android platform not only contained many open source warehouse and class, but also providing a convenient environment for application developers. The article use Android as develop platform, beginning system general design base on electronic map in Shanghai achieving reference of each export, road, public traffic information and so on among subway stations, then realize database management and Map serve application through integrate SQLite and Google Map. An exit and export inquires system in subway which convenient for traffic has been designed based on the features of the Android platform for mobile phone and the performance requirements. First introduces basic information of the android smart phone operating systems, and then the analysis of application software show that the characteristics of android platform are remarkable compatibility, and good expansibility, it also makes the summary of software development under Android common framework while importing these libraries. At last use Shanghai south station as application background, through example visual showing the availability, timeliness, of system application, supplying aid decision support of convenience trip for people.The innovation point of software design is use the initial coordinate independent design to solve the matching of subway station coordinates with the success.
