Question

I need to pass two params (lv and position) to a Asynctask doInBackground method but I don’t know how do it…

LoadSound.execute(lv,position)
class LoadSound extends AsyncTask<**[ListView,int]**, String, String>

thanks!

EDIT:

I have a listView. If you click in an item play sound (from Internet).

I would like show a progressDialog with Asynctask.

In the doInBackground method I have the itemOnClick:

HashMap<String, String> o = (HashMap<String, String>) lv.getItemAtPosition(position);

for this reason I need to pass lv and position.

try creating a constructor within your AsyncTask and whenever you create your object you can pass the parameters.
Something like this:

MyAsyncTask asynctask = new MyAsyncTask(10, true, myObject);
//this is how you create your object

 public class MyAsyncTask extends AsyncTask<Void, Void, Void>{

        int a;
        boolean b;
        Object c;

        public MyAsyncTask(int a, boolean b, Object c){
            this.a = a;
            this.b = b;
            this.c = c;
        }

        @Override
        protected Void doInBackground(Void... params) {
            if(b)
                c = a;
            return null;
        }

    }

and then you can just call asynctask.execute();

Edit: After reading your updated question I agree to Squonk to use a Service for example to play a background sound; also you can show a progress dialog before launching your AsynkTask (if this one is indefinetly) and dismiss it on your postexecute.
