| With the intelligent mobile Internet has entered a new era, smart mobile, smart phones. as represented by terminal applications are changing all aspects of social life. In the smart phone terminal operating system, currently the fastest growing most representative of the operating system is the Android platform launchde by Google. The Android platform is integrated into the general purpose computing concept, with the rapid increase in handheld devices, Android platform. offers the possibility for handheld devices for complex and flexible mobile intelligent application, hardware configuration,.Increasingly serious urban pollution, vehicle emissions a serious impact on people’s quality of life, low-carbon environmental protection has become the slogan of the city. Bus as the most to promote environmentally friendly transport, should be the top choice of the people.Android platform-based design and development of Changchun City, public transportation (bus, light rail and subway) Query Module, realizes Changchun City, public transport (bus, light rail and subway) line, site, time, transfer and other information inquiries. provides Changchun Municipal People’s daily travel taccurate, detailed bus route information to facilitate the use of public transportation resources to enable people to travel more convenient, but also to actively encourage the public to use public transport, to participate in building green cities played a catalytic role.In this paper, the above problems and needs, based on the Android platform using the Android SDK and JAVA Eclipse as a development tool, design and development of Changchun City, public transportation (bus, light rail and subway) Query Module. This module can be provided by the Changchun City Public Transport Group of the latest bus information, using the framework of the XML language system, preparation of the corresponding code using the JAVA language, in order to achieve the query capabilities of the bus lines, the site, transfer, etc. For more information, for people in Changchun City, with easy access to travel.Experimental and test run information inquiry procedures of this article the development of Changchun city bus (bus, light rail and subway) in all stable operation, based on the Android platform for mobile phones and mobile devices for different users to provide accurate public transport (bus, light rail and subway) information services, has a good application prospects. At the same time, it has a certain reference for other similar development workThis paper chapters are arranged as following:Chapter1, Introduction part introduces the research background, purpose and meaning, as well as the main work and papers organizational structure.Chapter2introduces the Introduction of the module development of related technologies, respectively Android background, the Android system framework, and how the Windows platform, the Android development environment and other related content.Chapter3, the overall design of the given subject and demand analysis, including the main function of the system, the division of the system modules and each module to achieve specific functions. Meanwhile, the form of relations in the database design, database and system processes are described in detail.Chapter4, the concrete realization of the logical structure and programming. Code file structure and detailed design of the core code, and describes the technical details of the modules involved in a functional detailed design process and realization of the difficulty.Chapter5, given the subject of the actual running and debugging, including the running interface and a brief description of the main functional modules of this system, further evidence developed in this paper the feasibility and practical value.Chapter6, the summary of this article and pointed out the future direction of further work. |
