java OutOfBoundsException [дубликат] - java, android, indexoutofboundsexception

проблемът ми е, че имам arrayList, когато щракнете върху SearchView за търсене на елемент, например когато пиша pepsi съобщението на системата за съжаление, вашето приложение е спряно.

Това е грешка в кода

            ImageLoader.getInstance().displayImage(ittList.get(position).getPic(), holder.ivPic1, new ImageLoadingListener()

Това е съобщение за грешка

Отговори:

Грешката, която получавате, е точно това, което казва, размерът на списъка е 3 и се опитвате да получите третия елемент, когато няма такъв. За да поправите това, направете

   ImageLoader.getInstance().displayImage(ittList.get(position-1).getPic(), holder.ivPic1, new ImageLoadingListener()

Кой ще получи елемента преди него, което вероятно е това, което сте искали. Не забравяйте, че той започва като 0 като индекс, а не 1. Така че трите елемента са в индекси 0, 1 и 2.
