Title Design and Implementation an Intelligent Train Schedule Software based on Android Platform
Abstract
This pager designs and realizes an intelligent train schedule software based on Android platform. This application is designed for the query of the train schedule based mainly on an offline database. Its main function modules include: station-to-station query，station query, and train number query, favorites, database updates, system settings (style, language, background), transfer query. The software is developed by development platform Eclipse with integrating ADT plug-in. Implement switching the main interface by using the view ViewPager. The association input function in station query and train number query is implemented by rewriting the method SimpleCursorAdapter. Jumping and parameter passing from one to another are completed by Intent and additional Bundle. The embedded SQLite database is used for query of the local data. The unlimited switch between station query and train number query is achieved under the help of the key values stored in the Stack. The sorting and filtering of the query results are completed by Collections tool class, and the SQL statements is optimized to shorten the time consumed by transfer query.
