如何在android数据库中插入数据后按顺序更改文本视图

// 创建数据库帮助类
public class DBHelper 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_ID = "id";
    private static final String COLUMN_TEXT = "text";

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

    @Override
    public void onCreate(SQLiteDatabase db) {
        String createTableQuery = "CREATE TABLE " + TABLE_NAME + " (" +
                COLUMN_ID + " INTEGER PRIMARY KEY AUTOINCREMENT, " +
                COLUMN_TEXT + " TEXT)";
        db.execSQL(createTableQuery);
    }

    @Override
    public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
        // 数据库升级操作
    }
}

// 在Activity中插入数据并更新文本视图
public class MainActivity extends AppCompatActivity {
    private TextView textView;
    private DBHelper dbHelper;

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

        textView = findViewById(R.id.textView);
        dbHelper = new DBHelper(this);

        // 插入数据
        SQLiteDatabase db = dbHelper.getWritableDatabase();
        ContentValues values = new ContentValues();
        values.put(DBHelper.COLUMN_TEXT, "Hello");
        db.insert(DBHelper.TABLE_NAME, null, values);

        // 查询并按顺序排序
        Cursor cursor = db.query(DBHelper.TABLE_NAME, null, null, null, null, null, DBHelper.COLUMN_ID + " ASC");

        // 更新文本视图
        StringBuilder stringBuilder = new StringBuilder();
        while (cursor.moveToNext()) {
            String text = cursor.getString(cursor.getColumnIndex(DBHelper.COLUMN_TEXT));
            stringBuilder.append(text).append("\n");
        }
        textView.setText(stringBuilder.toString());

        // 关闭数据库和游标
        cursor.close();
        db.close();
    }
}
