Each list item has all those sub-views, but each of sub-views has a different atributes (text, text color, ...) set durring each ListAdapter.getView(). This means that your convertView reference passed into getView will have Tag object set with all your sub-views ready to be customised for the given list element. > Considerating that I don't know in advance how many Texts in gra, same > thing for Text in bold and Text normal.
