Question

I have an activity object, myAct. myAct creates and calls my httpGetter object which extends AsyncTask

httpGetter does a great job! My progress bars work great. It gets the HTML data. I put a toast in the httpGetter.onPostExecute….. There’s the HTML!!!!

How do I pass that data back to the activity from the onPostExecute? I don’t even know what to google for this. I tried a few things, and all of the examples I saw either updated a textView or just showed the data in a toast, right in the onPostExecute. I want to resume things back in the calling Activity. In my httpGetter class, I created a method to set a handle to the calling Activity thinking I could call a method with the result String. No luck.

Answer 1

OK, so a bit more googling came up with the following solution.

myAct needed an interface

   public interface WebServiceListener 
{
    public void onHTTPGetComplete (ArrayList<String> arrayList);
}
public void onHTTPGetComplete  (ArrayList<String> arrayList) {
      String Response = arrayList.get(0);
      Toast worked = Toast.makeText(mainPage.this, Response, Toast.LENGTH_LONG);
      worked.show();
}

and the Async in the onPostExecute needed to call it

listener.onHTTPGetComplete (myList);
