iam с использованием MVVMCross 4.1.6 (проверено в 4.1.4) и имеет проблему с свойством элемента в наблюдаемой коллекции. Это происходит, когда я многократно переключаюсь между двумя вкладками, каждый с MvxRecyclerView и списком элементов, которые соединены вместе. В основном это обычный список, а один - фаворитный.MvxNotifyPropertyChanged Application Crash on SetProperty
Оба из этих списков готовьтесь данными в фоновом режиме, когда фрагмент обнаруживается с помощью этого метода, чтобы не уверен, что получает отображаются все новые данные:
private void updateChannels()
{
foreach (var category in CalCategories)
{
if (string.IsNullOrEmpty(m_searchString))
{
var channels = category.Channels.Where(o => o.Task == null).ToList();
if (category.Count != channels.Count)
{
category.Count = channels.Count;
}
if (channels.Count > 0)
{
if (!CalChannelList.Contains(category))
{
CalChannelList.Add(category);
}
if (category.Expanded)
{
foreach (var channel in channels)
{
if (!CalChannelList.Contains(channel))
{
CalChannelList.Add(channel);
}
}
}
}
}
else
{
var channels = category.Channels.Where(o => o.Name.Contains(SearchString) && o.Task == null).ToList();
if (category.Count != channels.Count)
{
category.Count = channels.Count;
}
if (channels.Count > 0)
{
if (!CalChannelList.Contains(category))
{
CalChannelList.Add(category);
}
if (category.Expanded)
{
foreach (var channel in channels)
{
if (!CalChannelList.Contains(channel))
{
CalChannelList.Add(channel);
}
}
}
}
}
}
}
Ошибка возникает там после определенного количества времени просто переключаться между вкладками и обратно, и всегда происходит на линии при наборе category.Count.

, кажется, связаны с креплениями и обновлением элементов пользовательского интерфейса. Может быть, каким-то образом ссылки на элементы будут очищены или не полностью освобождены при удалении элемента? Atleast без MvxBindings, который изменяется во время этого процесса, он не сбой.

Update 3 Видимо updateChannels() создает все больше и больше данных объектов. Я просто не уверен, что может быть причиной этого? Связывание с пользовательским интерфейсом, команда LinQ? Или я просто слепой?
Update 4 теперь я создал отдельный проект с только MvxRecyclerView и ObservableCollection в фрагменте. Если я нажму кнопку, я добавлю X новых объектов в список после очистки списка. Наблюдая за ним с помощью DeviceMonitor, объекты просто увеличиваются, поэтому либо я делаю что-то ужасно неправильно, либо что-то не так с компонентами, которые я использую.
https://github.com/Noires/MvxRecyclerViewLeakTest
Update 5 Хотя это была проблема, она не была связана с исходной задачи. Поэтому на данный момент я просто изменил сам MVVMCross, чтобы предотвратить его, и потом проверю реальную проблему.
Update 6 Выпуск открыт https://github.com/MvvmCross/MvvmCross/issues/1379
Если я правильно помню, что «SIGSEGV» в основном связан с проблемами управления памятью. Этот метод называется каждый раз, когда фрагмент становится видимым? – arsena
Да, это так. Помимо двух вкладок, я получил диаграмму, которая часто обновляется, а метод, стоящий за ней, пока не оптимизирован. Таким образом, это иногда приводит к небольшим GC_Issues, возможно, это связано вместе? – Cyriac
Может быть. Я постараюсь отправить решение в качестве ответа. – arsena
