android asynctask 回调,Android，我可以将AsyncTask放在单独的类中并进行回调吗？

我只是在学习AsyncTask，并希望将其用作单独的类，而不是子类。

例如，

class inetloader extends AsyncTask {

@Override

protected String doInBackground(String... urls) {

String response = "";

DefaultHttpClient client = new DefaultHttpClient();

HttpGet httpGet = new HttpGet(urls[0]);

try {

HttpResponse execute = client.execute(httpGet);

InputStream content = execute.getEntity().getContent();

BufferedReader buffer = new BufferedReader(

new InputStreamReader(content));

String s = "";

while ((s = buffer.readLine()) != null) {

response += s;

}

} catch (Exception e) {

e.printStackTrace();

}

return response;

}

@Override

protected void onPostExecute(String result) {

Log.e("xx",result);

// how do I pass this result back to the thread, that created me?

}

}

和main(ui)线程：

inetloader il = new inetloader();

il.execute("http://www.google.com");

//il.onResult()

//{

///do something...

//}

谢谢！
