Android : Implementing a progressDialog

I want to implement a progessDialog when my class is called. I know how to implement a progressDialog for a fragment class that uses AsyncTask. But here i have a fragment class that doesn't use asyncTask.

What this fragment does is showing some news details when it is called. I want to show a progressDialog while the news is loading and stop the progressDialog when the news is loaded and ready to display.How can i do this? I'm a newbie so please help me

My fragment class

package com.fortuna.cinemalk;

public class NewsDetailFragment extends Fragment {

    private ViewPager view1;
    private ViewPageAdapter adapter;
    private Activity activity;
    private CommonVariable commonVariable;


    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {

        View view = inflater.inflate(R.layout.newsdetail_fragment, container,
                false);

        activity = this.getActivity();

        commonVariable = (CommonVariable) activity.getApplication();

        view1 = (ViewPager) view.findViewById(R.id.listviewpager);

        adapter = new ViewPageAdapter(commonVariable.getNewsDescription(),
                Element.NEWS_DETAIL.getType(), activity);

        view1.setAdapter(adapter);



        return view;
    }

}
