Из-за чего может вылетать программа на Android при прокрутке кастомизированного списка?
Я создал программу с несколькими вкладками. На одной из них - ListView с кастомной разметкой из xml файла. В портретном режиме никаких проблем не возникает, но в альбомном весь список на экран не помещается и его можно прокрутить вниз, а если затем попытаться прокрутить обратно вверх, программа вылетает. Что может вызвать такой баг?
Да, действительно нулл поинтер.
