How to set number picker value when the min and max are the same?

I can't seem to figure out how for a value into the numberpicker. It always shows 0 when the min and max are the same. Is there any way to ovveride it? Here is my code.

int min = cursor.getInt(cursor.getColumnIndex(RestaurantElementsTable.KEY_MIN_QUANITY));
                int max = cursor.getInt(cursor.getColumnIndex(RestaurantElementsTable.KEY_MAX_QUANITY));
                int defaultQuanity = cursor.getInt(cursor.getColumnIndex(RestaurantElementsTable.KEY_DEFAULT_QUANITY));

                if ( max - min == 0){

                    ((NumberPicker) view).setValue(defaultQuanity);

                }else {

                    ((NumberPicker) view).setMaxValue(max);
                    ((NumberPicker) view).setMinValue(min);
                    ((NumberPicker) view).setWrapSelectorWheel(false);

                    ((NumberPicker) view).setValue(defaultQuanity);


                }

By default maxValue and minValue in NumberPicker is 0. So you need to set maxValue and minValue before using setValue.

For example:

if ( max == min) {
    ((NumberPicker) view).setMaxValue(defaultQuanity);
    ((NumberPicker) view).setMinValue(defaultQuanity);

    ((NumberPicker) view).setValue(defaultQuanity);
}
