Когда я открыл искомый элемент, он открывает первый элемент ListView, а не искомый. Даже если поиск и найти элементы успешно.
Я настраиваю адаптер с помощью Filterable и включаю Listview с помощью .setTextFilterEnabled(true), но это не работает.
Я видел, что должен реализовать публичный фильтр getFilter(), но понятия не имею, как это сделать.
Когда я набираю некоторые слова в EditText, например cel или 12, фильтр срабатывает, но результат всегда один и тот же: первые два элемента в Listview, независимо от того, что находится в Listview (содержимое списка случайно).
