Implementation of SQLite paging reading improved by Android

Generally speaking, Android itself includes SQLite, which is commonly used in embedded systems, which eliminates the need for developers to transplant and install themselves. SQLite supports most SQL92 standards. Many commonly used SQL commands can be used on SQLite. In addition, Android also provides a series of customized methods to simplify the operation of SQLite database. However, for programs with cross platform requirements, it is recommended to use standard SQL statements. After all, it is easy to migrate between multiple platforms.

First, post the result diagram of the program running in this paper:

The example program in this paper mainly explains the basic usage of SQLite, such as creating a database, querying data tables with SQL commands, inserting data, closing the database, and using GridView to realize a paging bar (about the usage of GridView) to display data in pages.

The source code of pagebuttons.xml of the page bar is as follows:

The source code of main.xml is as follows:

The Java program source code is as follows:

Interested readers can test this example code, hoping to play a certain reference role in Android project development.
