                                FragmentDialog newFragment = new FragmentDialog();
                                newFragment.setArguments(args);
                                newFragment.show(getActivity().getSupportFragmentManager(), "TAG");

                                showTheDialog();
                     }
             });
 }
protected void showTheDialog() {
    FragmentManager fm = getActivity().getSupportFragmentManager();
    FragmentDialog overlay = new FragmentDialog();
    overlay.show(fm, "FragmentDialog");

 }

FragmentDialog

   public class FragmentDialog extends DialogFragment {

    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {
        Dialog dialog = super.onCreateDialog(savedInstanceState);
        dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
        //dialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.YELLOW));
        dialog.getWindow().setLayout(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);

        return dialog;
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle
            savedInstanceState) {
        View view = inflater.inflate(R.layout.prompt_quantity, container);

        // tab slider
        sectionsPagerAdapter = new SectionsPagerAdapter(getChildFragmentManager());

        // Set up the ViewPager with the sections adapter.
        viewPager = (ViewPager) view.findViewById(R.id.modifierpager);
        viewPager.setAdapter(sectionsPagerAdapter);

        Bundle mArgs = getArguments();
        pName = mArgs.getString("key","asdasd");

        final TextView tpn = (TextView)getView().findViewById(R.id.gtestproductname);
        tpn.setText(pName);
}

Answer 1

  newFragment.show(getActivity().getSupportFragmentManager(), "TAG");

                            showTheDialog();

you need not call show twice, this logic draws the view twice. That is why you have the anomaly. Remove the second one.
