(The project mainly includes the following primary files: 1. DbNews.java is the class corresponding to the database and database tables, including the internal class News, which corresponds to the news table. It mainly provides column name citation and table encapsulation. 2. DBHelper.java encapsulates the database operation class, including multiple operations on the database. Its internal class DBOpenHelper is inherited from SQLiteOpenHelper and serves as the creation and upgrade of databases. Five records are stored while initializing the database. 3. SQLiteDemo.java, inherited from ListActivity, is about displaying records in the database. 4、SeeDetailNews。 Java displays each detailed record. 5. Layout files are no longer introduced.
