[kenkosmowski]

On using MvxRecyclerView, NotSupportedException occurs:

Steps to reproduce

1. Use Android Support Library 23.3.0 and latest MvvmCross packages (4.1.6. / 4.1.7)
2. Create View and add MvxRecyclerView

MyView.axml

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
    <RelativeLayout
        android:orientation="vertical"
        android:layout_width="match_parent"
        android:layout_height="match_parent">
      <MvvmCross.Droid.Support.V7.RecyclerView.MvxRecyclerView
            android:id="@+id/RegistrationRegion_AddressSearchItems"
            android:layout_width="match_parent"
            android:layout_height="match_parent" />
  </RelativeLayout>
</ScrollView>

1. Exception will be thrown at SetContentView()

[kjeremy]

Give us some code. There should be more to the stacktrace if you continue on.

[kenkosmowski]

added axml and stacktrace to original post

[kjeremy]

Might be a dup of #244 . Can you try the workaround in that bug?

[tbalcom]

The workaround suggested by @kjeremy worked for me. The workaround consists of adding Resources\values\attrs.xml file to your Droid project with the following content:

<?xml version="1.0" encoding="utf-8" ?>
<resources>
  <declare-styleable name="MvxRecyclerView">
    <attr name="MvxItemTemplateSelector" format="string" />
  </declare-styleable>  
</resources>

[kenkosmowski]

Doesn't work for me. I get following error message during build:

Attribute "MvxItemTemplateSelector" has already been defined

[kenkosmowski]

Deleting bin & obj solved it. Workaround works for me now, too.

Hello, I am getting this error on using one of our custom control. The error is only reproducible if I run the app in debug mode on Android 6.0.1, In release mode the custom control is rendered fine.
