             LayoutInflater inflater = (LayoutInflater)getActivity().getSystemService
                      (Context.LAYOUT_INFLATER_SERVICE);
             View v1 =inflater.inflate(R.layout.dialog_layout, null);
            new AlertDialog.Builder(getActivity()).setTitle("Thank you")
            .setView(v1)
