Сбой приложения при прокрутке вверх или вниз

Question

Я новичок в Android Studio и столкнулся с проблемой. У меня есть андроид приложение, которое происходит сбой, если я прокрутки вверх или вниз, первые 12 изображений отображаются нормально, но я не могу показаться, чтобы прокрутить, чтобы увидеть другие изображения, которые я закодированы в

Answer 1

Вы получаете в OutOfMemoryException. Это именно то, что он говорит. Содержимое элементов ListView, вероятно, слишком много для обработки. Убедитесь, что вы не используете изображения с большим размером файла.
