Analysis of data storage method using SQLite developed by Android

This paper describes the method of storing data using SQLite in Android development. Share with you for your reference, as follows:

We have mentioned several file operations, such as shared reference and sdcard. In fact, Android also provides another storage method, SQLite. As long as you have studied the database, you can master this. Let's get this together with me.

1. Install a SQLite developer, which is used to open the database generated by Android. The software can be found by random search. Just open the software and click "database" -- > "registered database". It's best to explore by yourself

2. Write a business class into a database and database table, as shown below

When the database and tables are ready, you can do the next step

3. Prepare business categories for addition, deletion, modification and query

Note the usage of getreadabledatabase and getwritabledatabase. Getreadabledatabase is used for simple data query and the latter is used for data modification. In addition, it should be noted that the data type of SQLite has no effect, just for the mutual cooperation of programmers.

4. Write JUnit for Android

Data is generated after execution, and the record with ID 11 has been deleted
