Android MVVMCross嵌套回收视图内存不足问题

我曾尝试结合mvvmcross框架创建嵌套的recyclerview，该框架实际上非常容易工作，但现在我遇到了内存不足的异常

脚本 我有一个大约3000个条目的列表，这些条目的名称复杂而冗长，分为8个类别。用户可以通过复选框选择条目，以便稍后将其分配给任务

即使听起来有太多的条目，如果用户有一些背景知识，实际上也很容易浏览它们，所以我现在不想更改它

代码 首先是类别和条目（通道）的简化数据模型：

然后是刚刚被MVVMCross映射的axml文件：

fragment_channels.axml

<?xml version="1.0" encoding="utf-8"?>

    xmlns:local="http://schemas.android.com/apk/res-auto"

    android:layout_height="fill_parent">
    <SearchView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text=""
        android:iconifiedByDefault="false"
        local:MvxBind="Query SearchString" />
    <MvxRecyclerView

        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:scrollbars="vertical"
        android:cacheColorHint="#00000000"
        android:choiceMode="singleChoice"
        local:MvxItemTemplate="@layout/listitem_channelcategory"
        local:MvxBind="ItemsSource Categories" />
</LinearLayout>

listitem_channelcategory.axml

 <?xml version="1.0" encoding="utf-8"?>
    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:local="http://schemas.android.com/apk/res-auto"

        android:layout_marginRight="5dp"
        android:padding="10dp"
        android:textColor="@color/black"
        android:textStyle="bold"
        local:MvxBind="Text (Name+Channels.Count)" />
  <MvxRecyclerView

        android:choiceMode="singleChoice"
        local:MvxItemTemplate="@layout/listitem_channel"
        local:MvxBind="ItemsSource Channels" />
</LinearLayout>

listitem_channel.axml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:local="http://schemas.android.com/apk/res-auto"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:background="@drawable/roundborder">
    <CheckBox
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:gravity="center_vertical"
        android:layout_gravity="center_horizontal"
        android:layout_marginRight="5dp"
        android:padding="10dp"
        android:textColor="@color/black"
        local:MvxBind="Text Name; Checked Selected" />
</LinearLayout>

问题 所以基本上我有一个ViewModel，它被分配给一个视图（片段\通道）显示一个类别列表（listitem \类别），其中每个类别显示一个通道列表（listitem \通道）。使用MVVMCross框架处理所有事情。它工作得很好，直到我向下滚动到另一个类别，然后它只是冻结了一段时间，几次之后它崩溃了，出现了内存不足异常。Atm我可以通过给内部的recyclerviews一个固定的大小来延迟它

有没有人知道我可以改变什么，或者我做错了什么？也许我不应该只是一个嵌套的recyclerview，但是到这一点的处理非常简单和直观

MVVMCross Android支持版本和Co为4.1.5，Xamarin Android支持库为23.3.0
