How to define ListView in AsyncTask?

Question

I'm extending in my class AsyncTask and I have a context passed however from another activity. So I tried this:

        listview = (ListView) findViewById(R.id.listview1);

Error:

The method findViewById(int) is undefined for the type loadSomeStuff

I tried this also:

        listview = (ListView) ctx.findViewById(R.id.listview1);

Error:

The method findViewById(int) is undefined for the type Context

How can I get over this error?

it is either View.findViewById() or Activity.findViewById().

try

listview = (ListView) ((Activity)ctx).findViewById(R.id.listview1);

@AndroidArabia what do you mean? You can cast a Fragment to Fragment – Boris Mocialov Aug 03 '13 at 22:49
in your codes though you typed "Activity", i want fragment. what to do??? @MacialovBoris – Aug 03 '13 at 22:51
listview = (ListView) ((Fragment) ctx) .findViewById(R.id.listview1); doesn't work – Aug 03 '13 at 22:52
@AndroidArabia this is not your original question. Try take a look here: http://stackoverflow.com/a/6496013/1276374 (inflate your fragment and use findViewById on that view) – Boris Mocialov Aug 03 '13 at 22:56
but then, how can i initialize Container (ViewGroup)?? – Aug 03 '13 at 23:02
@AndroidArabia which ViewGroup? – Boris Mocialov Aug 03 '13 at 23:04
