Android, can I put AsyncTask in a separate class and have a callback?

Question

I\'m just learning about AsyncTask and want to use it as a separate class, rather then a subclass.

For example,

class inetloader extends AsyncTask&l

Use a interface. Something like:

interface CallBackListener{
  public void callback();
}

Then do this in your UI thread:

inetloader il = new inetloader();
li.setListener(this);
il.execute("http://www.google.com");

In inetloader, add:

   CallBackListener mListener;

   public void setListener(CallBackListener listener){
     mListener = listener;
   }

then In postExecute(), do:

   mListener.callback();
