如何将我的数据库连接到我的android应用

public class DBHelper extends SQLiteOpenHelper {
    private static final String DATABASE_NAME = "mydatabase.db";
    private static final int DATABASE_VERSION = 1;

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

    @Override
    public void onCreate(SQLiteDatabase db) {
        // 创建表结构
        String createTableQuery = "CREATE TABLE mytable (id INTEGER PRIMARY KEY, name TEXT)";
        db.execSQL(createTableQuery);
    }

    @Override
    public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
        // 升级数据库版本时执行的操作
        if (oldVersion < 2) {
            // 添加新的表或字段
            String alterTableQuery = "ALTER TABLE mytable ADD COLUMN age INTEGER";
            db.execSQL(alterTableQuery);
        }
    }

    public void insertData(String name) {
        SQLiteDatabase db = getWritableDatabase();
        ContentValues values = new ContentValues();
        values.put("name", name);
        db.insert("mytable", null, values);
        db.close();
    }

    public List<String> getAllData() {
        List<String> data = new ArrayList<>();
        SQLiteDatabase db = getReadableDatabase();
        Cursor cursor = db.rawQuery("SELECT * FROM mytable", null);
        if (cursor.moveToFirst()) {
            do {
                String name = cursor.getString(cursor.getColumnIndex("name"));
                data.add(name);
            } while (cursor.moveToNext());
        }
        cursor.close();
        db.close();
        return data;
    }
}
