如果不在数据库中，Android Studio SQLite保存标题？

// 创建SQLite数据库类
public class MyDatabaseHelper extends SQLiteOpenHelper {
    private static final String DATABASE_NAME = "my_database.db";
    private static final int DATABASE_VERSION = 1;
    
    public MyDatabaseHelper(Context context) {
        super(context, DATABASE_NAME, null, DATABASE_VERSION);
    }
    
    @Override
    public void onCreate(SQLiteDatabase db) {
        // 创建表结构
        String createTableSql = "CREATE TABLE titles (_id INTEGER PRIMARY KEY AUTOINCREMENT, title TEXT)";
        db.execSQL(createTableSql);
    }
    
    @Override
    public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
        // 数据库升级时的操作
        String dropTableSql = "DROP TABLE IF EXISTS titles";
        db.execSQL(dropTableSql);
        onCreate(db);
    }
}

// 在Activity中保存标题到数据库
public class MainActivity extends AppCompatActivity {
    private MyDatabaseHelper dbHelper;
    
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        
        dbHelper = new MyDatabaseHelper(this);
        
        // 打开数据库连接
        SQLiteDatabase db = dbHelper.getWritableDatabase();
        
        // 定义数据模型
        ContentValues values = new ContentValues();
        values.put("title", "Hello World");
        
        // 插入数据
        db.insert("titles", null, values);
        
        // 关闭数据库连接
        db.close();
    }
}
