一个代码较任何的Android机票预订客户端使用,实现了机票查询,酒店查询,订单管理,订单批阅,系统设置等功能,使用了LIB库ksoap2-android-assembly-2.3-jar-with-dependencies.jar,已放入下载包内,为自定义主界面而配有适配器。数据库部分:在SQLiteOepnHelper的子类傍边,必须有该框架函数,必须通过super调用父类傍边的框架函数,只有调用了DatabaseHelper对象的getReadableDatabase()方法,或者是getWritableDatabase()方法之后,才会创建,或打开一个数据库。

(A code is more used than any Android air ticket booking client, which realizes the functions of air ticket query, hotel query, order management, order review, system settings, etc. It uses the LIB library ksoap2-android-assembly-2.3-jar-with-dependencies.jar, which has been put into the download package, and is equipped with an adapter for self defining the main interface. Database part: The framework function must exist near the subclass of SQLiteOepnHelper, and the framework function near the parent class must be called through super. A database can be created or opened only after the getReadableDatabase() method or getWriteableDatabase() method of the DatabaseHelper object is called.)
