如何显示在AsyncTask的doInBackground中运行的BufferReader中存在的数据

public class MyAsyncTask extends AsyncTask<Void, String, Void> {

    @Override
    protected Void doInBackground(Void... voids) {
        try {
            // 从某个数据源读取数据，例如从网络连接中读取数据
            URL url = new URL("http://example.com/data.txt");
            HttpURLConnection connection = (HttpURLConnection) url.openConnection();
            BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream()));

            String line;
            while ((line = reader.readLine()) != null) {
                // 将读取到的数据作为参数传递给onProgressUpdate方法
                publishProgress(line);
            }

            reader.close();
            connection.disconnect();
        } catch (IOException e) {
            e.printStackTrace();
        }

        return null;
    }

    @Override
    protected void onProgressUpdate(String... values) {
        // 更新UI界面来显示读取到的数据
        String data = values[0];
        textView.setText(data); // 假设textView是一个TextView组件
    }
}
