SetProperty上的MvxNotifyPropertyChanged应用程序崩溃

Question

iam使用MVVMCross 4.1.6(在4.1.4上也尝试过)，并且在可观察集合中的项的属性存在问题。当我在两个选项卡之间重复切换时，就会发生这种情况，每个选项卡都有一个MvxRecyclerView和一个连接在一起的项目列表。基本上一个是普通列表，一个是收藏夹。

当片段通过这种方法显示时，这两个列表都是由后台的数据准备的，以确定是否显示了所有新数据：

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);
}
}
}
}
}
}
}

在选项卡之间来回切换一段时间后，错误就会发生，并且总是发生在类别所在的行。计数已设置。

更新

似乎与绑定和更新ui元素有关。当项目被删除时，元素的引用可能会被清除，或者没有完全释放？至少没有在此过程中更改的MvxBindings，它不会崩溃。

更新2

public abstract class BaseCategory : MvxNotifyPropertyChanged, IChannelItem
{
public bool Expanded { get; set; }
public int FavoriteCount
{
get { return m_iFavoriteCount; }
set { SetProperty(ref m_iFavoriteCount, value); }
}
public int Count
{
get
{
return m_iCount; 
}
set
{
SetProperty(ref m_iCount, value);
}
}
public string Name { get; set; }
protected BaseCategory(string sName)
{
Expanded = false;
Count = 0;
FavoriteCount = 0;
Name = sName;
}
private int m_iCount;
private int m_iFavoriteCount;
public ChannelItemTypes CItemType { get { return ChannelItemTypes.Category; } }
}

而被选中的布局是我的一个多版本模板选择器：

</LinearLayout>

Update3显然updateChannels()方法创建了越来越多的数据对象。我只是不确定是什么原因造成的？绑定到UI元素，即LinQ命令？还是我只是瞎了眼？

更新4我现在创建了一个单独的项目，其中只有一个MvxRecyclerView和一个片段中的ObservableCollection。如果我点击按钮，我会在清除列表后将X个新对象添加到列表中。通过使用DeviceMonitor观察，对象不断增加，所以要么我做错了什么，要么我使用的组件出了问题。

https://github.com/Noires/MvxRecyclerViewLeakTest

更新5虽然这是一个问题，但与原始问题无关。因此，目前我只是自己更改了MVVMCross以防止它，并将在之后检查真正的问题。

更新6问题在上打开https://github.com/MvvmCross/MvvmCross/issues/1379

Answer 1

正如我在评论中提到的，SIGSEGV主要与内存管理问题有关。

RecyclerView的优点之一是可以添加元素，而无需刷新整个列表。这样可以节省大量内存。

在updateChannels方法中，您将清除列表(可能是recyclerView的来源)，然后再次读取元素。这是一个非常糟糕的解决方案，尤其是对于大名单来说。这样一来，每次更改选项卡时，整个recyclerView都会更新，这会严重影响性能。

您应该做的是检查是否有新数据，并且只添加新元素。

为此，您可能会找到一个更好的示例，但一个简单快速的解决方案是newList.Except(recyclerViewSourceList)。这将为您提供来自新来源的元素，而回收器视图不包含这些元素。查看此项以了解更多详细信息：https://stackoverflow.com/a/3944821/3423468

Answer 2

目前的问题是，在不同的视图模型中重用服务中的一个条目池似乎并不能正确地清除绑定，因为只有条目的引用被清除，而不是条目本身。

目前我的解决方案是为每个列表和每个条目添加一个额外的绑定项。因此，如果它被删除，我会确保绑定也被删除，或者至少在GC清理之前不再使用

仍然希望有一个更好的解决方案，因为我有点需要为每个条目添加一个额外的活页夹项目，但有关更多信息，请参阅：

更新：问题(https://github.com/MvvmCross/MvvmCross/issues/1379)解决了。感谢克杰雷米的辛勤工作
