Fatal Exception при прокрутке списка ViewView

Приложение работает нормально, пока вы не прокрутите несколько раз в ListView.Fatal Exception при прокрутке списка ViewView

Это ошибка, которую я получил от LOGCAT. Код для настраиваемого базового адаптера, который я использовал, находится ниже него.

Что такое строка -> HomeScreen.java:485 – Atrix1987

Линия содержит holder.photoText.setText (timeStampHandler.get_dayFullLenght (unixTime)); – SARose

Исключение означает, что photoText == null. Это либо потому, что:

monthArray.get(position).photoThumbnailArrayList.size() != 3
или R.layout.photo_card_3 не имеет TextView с идентификатором @+id/photoText

Проверьте оба случая!

Я несколько исправил проблему, сделав 'convertView = null;' в методе getView до того, как какой-либо из кода будет запущен. – SARose

OK; проблема заключается в вашем 'TimeLineViewHolder', а затем: это означает, что при повторном использовании строки в ней нет (иногда) никакого' photoText'. Используйте либо разные ViewHolders, либо используйте один и тот же макет для всех строк, а некоторые поля видны/ушли. – etienne
