如何在Android SQLite中插入多行？

// 创建SQLiteOpenHelper子类
public class MyDatabaseHelper extends SQLiteOpenHelper {
    private static final String DATABASE_NAME = "mydatabase.db";
    private static final int DATABASE_VERSION = 1;
    private static final String TABLE_NAME = "mytable";
    private static final String COLUMN_NAME = "name";
    private static final String COLUMN_AGE = "age";

    public MyDatabaseHelper(Context context) {
        super(context, DATABASE_NAME, null, DATABASE_VERSION);
    }

    @Override
    public void onCreate(SQLiteDatabase db) {
        // 创建表格
        String createTableQuery = "CREATE TABLE " + TABLE_NAME + " (" +
                COLUMN_NAME + " TEXT, " +
                COLUMN_AGE + " INTEGER)";
        db.execSQL(createTableQuery);
    }

    @Override
    public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
        // 升级数据库
        String dropTableQuery = "DROP TABLE IF EXISTS " + TABLE_NAME;
        db.execSQL(dropTableQuery);
        onCreate(db);
    }
}

// 在适当的位置插入多行数据
MyDatabaseHelper dbHelper = new MyDatabaseHelper(context);
SQLiteDatabase db = dbHelper.getWritableDatabase();

ContentValues values = new ContentValues();
values.put(COLUMN_NAME, "John");
values.put(COLUMN_AGE, 25);
db.insert(TABLE_NAME, null, values);

values.clear();
values.put(COLUMN_NAME, "Jane");
values.put(COLUMN_AGE, 30);
db.insert(TABLE_NAME, null, values);

// 插入更多行数据...

db.close();
