The Design And Implementation Of The Taohai System Based On Geographic Location Under The Android Platform

In recent years,with the rapid development of the mobile phone industry,a variety of mobile applications have emerged.The location-based service(LBS cloud service)application has become the development trend of the mobile Internet.This paper combines LBS technology to design and implement a geographic location-based Taohai system under the Android platform.This system uses the user behavior in MVC mode as an entry point to provide geographic location-based seafood trading services.And it has good function,friendly interface and good user experience.Firstly,this paper focuses on the geographic location-based Taohai system under the Android platform,and studies the related technologies of LBS service,the system architecture of Android platform and functional components such as Map View and the application of each technology.In addition,key technologies such as positioning technology and GIS related technologies are also analyzed.Then,after in-depth study on the development necessity of the geographic location-based Taohai system and the sales characteristics of seafood products under the Android platform,this paper determines the specific development requirements of the system and preliminarily designs the working principle and system application architecture.According to the functional requirements of the geographic location-based Taohai system under the Android platform,the system is divided into four functional modules: registration/login module,system function module,personal center module and commodity transaction module.And the article analyzes and designs each functional module and database structure and database table in detail.Finally,based on the detailed design of the system,the paper presents in detail the various functional modules of the system implementation,such as: LBS service positioning,spatial computing function,and specific implementation of Android client user login registration,product map,publishing transaction,query Products,auctions,group purchases,early adopters,payment orders,evaluations,etc.,the article has detailed the above functions.In addition,the system has made a brief summary and a good expectation for the future development and improvement of the system.The geographic location-based Taohai system under the Android platform is developed based on the high-tech LBS open platform and adopts a new development method of LBS service.The purpose is to provide users with a time-and space-free platform for publishing transaction information,purchasing nearby seafood products in various procurement methods,and timely evaluation.Its application can greatly reduce the waste of marine resources,respondto the sociology for revenue and expenditure,and reduce the trend of spending.
