Попытка переопределить getView в SimpleCursorAdapter дает NullPointerExceptio

Очень ценил бы любую справку, или подсказка на должны были пойти затем.

Я пытаюсь изменить содержание строки в ListView программно. В одной строке существует 3 TextView и ProgressBar. Я хочу анимировать ProgressBar, если столбец 'результата' текущей строки является нулем.

После чтения некоторых учебных руководств и документов, я пришел к выводу, что LayoutInflater должен использоваться и getView() - переопределенный. Возможно, я неправ в этом.

Если я возвращаюсь row = inflater.inflate(R.layout.row, null); от функции это дает NullPointerException.

Вот код:

    private final class mySimpleCursorAdapter extends SimpleCursorAdapter {

    private Cursor localCursor;
    private Context localContext;

    public mySimpleCursorAdapter(Context context, int layout, Cursor c, String[] from, int[] to) {
        super(context, layout, c, from, to);            
        this.localCursor = c;
        this.localContext = context;

    }

    /**
     *    1. ListView asks adapter "give me a view" (getView) for each item of the list
     *    2. A new View is returned and displayed
     */
    public View getView(int position, View  convertView, ViewGroup  parent) {
        View row = super.getView(position, convertView, parent);

        LayoutInflater inflater = (LayoutInflater)localContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

        String result = localCursor.getString(2);
        int resInt = Integer.parseInt(result);

        Log.d(TAG, "row " + row);

        // if 'result' column form the TABLE is 0, do something useful:
        if(resInt == 0) {           
            ProgressBar progress = (ProgressBar) row.findViewById(R.id.update_progress);
            progress.setIndeterminate(true);

            TextView edit1 = (TextView)row.findViewById(R.id.row_id);
            TextView edit2 = (TextView)row.findViewById(R.id.request);
            TextView edit3 = (TextView)row.findViewById(R.id.result);
            edit1.setText("1");
            edit2.setText("2");
            edit3.setText("3");
            row = inflater.inflate(R.layout.row, null);             
        }

        return row;
    }
