Android,我可以把AsyncTask放在一个单独的类中并有一个回调吗?

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<String, Void, String> {
@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?
}
}
和主(ui)线程:
inetloader il = new inetloader();
il.execute("http://www.google.com");
//il.onResult()
//{
///do something...
//}
谢谢!
