Условия использования IF в RecyclerView

Question

Мое приложение это Интернет-рынок. Я могу добавить товар в корзину. Я пытаюсь изменить значок из «добавить в корзину» на «в корзину». Но это работает неправильно. Если я добавлю только один продукт и прокручу вниз, изменится иконка других продуктов. В адаптере RecyclerView OnBindViewHolder я использую условие , если.

if (getTableBasket().contains(p.getId())) 
    prudactViewHolder.btn_buy.setBackgroundResource(R.drawable.tool); 
else 
    prudactViewHolder.btn_buy.setBackgroundResource(R.drawable.tool1); 

.... 

ArrayList<Integer> getTableBasket(){ 

     ArrayList<Integer> id_list = new ArrayList<>(); 
     dbHelper = new DBHelper(mContext); 
     SQLiteDatabase db = dbHelper.getWritableDatabase(); 
     Cursor c = db.query("basket", null, null, null, null, null, null); 
     if (c.moveToFirst()) { 
      int id_prudactColIndex = c.getColumnIndex("id_prudact"); 
      do { 
       id_list.add(c.getInt(id_prudactColIndex)); 

      } while (c.moveToNext()); 
     } else 
      Log.d(LOG_TAG, "In basket 0 rows"); 
     c.close(); 

     return id_list; 
    } 

EDIT Хорошо, я получить данные от сервера в формате JSON. И отобразите его в recyclerview. Я могу добавить прудакт в корзину, для этого я создаю таблицу «Букет». Когда пользователь добавляет товар в корзину, данные pudact добавляются в «Букет». И, например, пользователь закрывает приложение. И снова вернемся к приложению, он может найти, что его добавленный продукт в другой значок и не добавил продукт в другой значок.

моя дб структура

db.execSQL("create table basket (" 
       + "id integer primary key autoincrement," 
       + "id_prudact integer," 
       + "name text," 
       + "id_image integer," 
       + "count integer," 
       + "price integer," 
       + "priceOld integer," 
       + "nomer_zakaz text" + ");"); 

     db.execSQL("create table favorite (" 
       + "id integer primary key autoincrement," 
       + "id_prudact integer," 
       + "name text," 
       + "id_image text," 
       + "count integer," 
       + "price integer," 
       + "priceOld integer" + ");");

Answer 2

Лучше вы можете сохранить продукт в корзину или нет в классе модели например:

Product{ boolean isInCart; ..... }

и предоставить этот тип arraylist в адаптере для ресайклеров. то только одно условие:

if (getItem(position).isInCart()) 
prudactViewHolder.btn_buy.setBackgroundResource(R.drawable.tool); 
else 
prudactViewHolder.btn_buy.setBackgroundResource(R.drawable.tool1); 

в противном случае он будет делать forloop по каждому пункту, который плохо для пользовательского интерфейса, а также для памяти.

Если вы все еще не в состоянии получить его озираться по этой ссылке: http://amolsawant88.blogspot.in/2015/08/easy-way-to-highlight-selected-rowitem.html вещь отличается, но он меняется фон вы хотите изменить изображение только контекст отличается, но дело в том же.
