Java insert data from database sqlite android

To insert data into an SQLite database in Android, you can use the SQLiteDatabase class and the ContentValues class.

Here is an example of how to insert data into an SQLite database in Android:

import android.content.ContentValues;
import android.database.sqlite.SQLiteDatabase;

public class MainActivity extends AppCompatActivity {
    private static final String TABLE_NAME = "users";

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        // Open the database
        SQLiteDatabase db = openOrCreateDatabase("app.db", MODE_PRIVATE, null);

        // Create the table if it doesn't exist
        db.execSQL("CREATE TABLE IF NOT EXISTS users (id INTEGER PRIMARY KEY, name TEXT, age INTEGER)");

        // Create a new ContentValues object
        ContentValues values = new ContentValues();

        // Insert data into the table
        values.put("id", 1);
        values.put("name", "John Smith");
        values.put("age", 30);
        long rowId = db.insert(TABLE_NAME, null, values);

        // Close the database
        db.close();
    }
}

In this example, the SQLiteDatabase class is used to open or create an SQLite database. The execSQL() method is used to create a table if it doesn't exist, and the ContentValues class is used to store the data to be inserted. The insert() method is then used to insert the data into the table.

For more information on working with SQLite databases in Android, you can refer to the Android documentation.
