Android Volley and the usage of Tasks or Threads in the response

Issue

in my App i do different requests to get the HTML code of a website. After that, the App parses the HTML, maybe another request will performed and parsed. At the end a ListView is filled with the parsed data.

Now i read that Volley runs all code in the onResponse method on the UI Thread. So maybe it is better to do the parsing in a new thread. I implemented it as follows.

new Thread(new HTMLSiteParsingTask(response)).start();

class HTMLSiteParsingTask implements Runnable {
  String mResponse;
  HTMLSiteParsingTask(String response) {
    mResponse = response;
  }
  public void run() {
  //do something...
  callerActivity.addData(dataHashMap);
  }
}

At the end of the processing i call a method of the MainActivity to add the data to the Listview "callerActivity.addData(dataHashMap);". This Method does the following:

runOnUiThread(new AddItemsTask(ItemList));

Is there a difference between AsyncTask and Thread so that i should use one of them? Or doesn't matter? Is there maybe a better way to do that stuff?

Thank you for your answers

Solution

Implement a custom request. Place your parsing logic in the parseNetworkResponse method - it will be called by Volley from a worker thread.
