           loadControls();
           getPassingValue();


            ParserMethod parserMethod=new ParserMethod();
            //questionsObj=parserMethod.parseQuestionDetailsFor(passingFeature,numOfQuestion,passingSubject,passingChapter);

Using AsyncTask.. just like below.. code is not exactly right.. its just to give an idea..

classs backgrnd extends Asynctask{

protected object onPreExecute(){
//display dialog
}

protected object doInBackgroung(Object... arg){
//fetch data
}

protected object onPostExecute(Object result){
//dismiss dialog
}
}

You can Use AsyncTask class for this.The class is designed so that you can do something in the background.It has overridden method onPreExecute where you can show the ProgressDialog and on doInBackground method load your question.On preExecute method cancel the dialog and update your UI
