Progress dialog not showing

Question

I have two spinners one named cuisine and other area. I m calling the new Thetask().execute on activity load with "init" as argument. And on that the spinners should be set from webservice with the cuisines available and arealist.(methods for that not included here). And initially the spinners will have "All " selected so the listview"restaurantlist" should have all the restaurants. And when the user changes the cuisine or the area from spinners, the restaurantlist listview should be updated with a progressdialog been displayed. Now My problem is that all the code is working but the progress dialog starts to display after the listview is populated and that progressdialog never stops until back button is pressed.Any solution for this will be a gr8 help. Thanks in advance.

public class Thetask extends AsyncTask {

     String flagdopost="",x,y;       
     @Override 
     public void onPreExecute() 
     {   
        pg =new ProgressDialog(Restaurantlistdisplay.this);
        pg.setMessage("fetching info....");
        pg.setIndeterminate(true);
        pg.setCancelable(true);
        Log.i("inside preexecute","in pre execute");
        pg.show();

     }   

     public Void doInBackground(String... params)
     {          
        if(params[0].equalsIgnoreCase("init"))
        {
            tempcuisinenamelist = getCuisines();    
            tempcuisinenamelist.add(0,"All");

            tempareanamelist=getAreanames(cid, sid, cityid);
            tempareanamelist.add(0,"All");

            flagdopost="init";  
            Log.i("inside doinbackground 1st",flagdopost);
        }

        else if(params[0].equalsIgnoreCase(""))
        {
            firequery();
            flagdopost="itemselected";

        }
        else if(params[0].equalsIgnoreCase("itemclick"))
        {
            //sendid=getRestaurantId(params[1],params[2]);

Answer 1

try this in postexecute

 if(pg.isShowing())
{
pg.dismiss();
}

and What is getCuisines();? do you have any ProgressDialog over there?

if its nested activity then try

  ProgressDialog dialogGoog = new ProgressDialog(getParent());
