RecyclerView in Fragment of ViewPager results in InflateException - xamarin.android

Question

I have a TabLayout with Fragments. In one of the Fragments, I want to add a RecyclerView. I have implemented the code for it and deployed it, but when I start the app I get the following error at tabLayout.SetupWithViewPager(viewPager):
Android.Views.InflateException: Binary XML file line #15: android.support.v7.widget.AppCompatTextView cannot be cast to android.widget.Button
and sometimes just
Android.Views.InflateException: Timeout exceeded getting exception details
I tried to copy the same code for the RecyclerView in a new Project but there just in the MainActivity and it worked. So I'm doing something else wrong...
My Code:
Main.axml:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.design.widget.TabLayout
android:id="#+id/tablayout_navigation"
android:layout_width="match_parent"
app:tabTextColor="#ffffff"
app:tabSelectedTextColor="#08aeab"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:background="?attr/colorPrimary"
android:elevation="4dp" />
<android.support.v4.view.ViewPager
android:id="#+id/pager"
android:layout_width="match_parent"
android:layout_height="fill_parent"
android:layout_margin="0dp" />
</LinearLayout>
Overview.axml:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"

android:minWidth="25px"
android:minHeight="25px">
<android.support.v7.widget.RecyclerView
android:id="#+id/recyclerView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scrollbars="vertical">
</android.support.v7.widget.RecyclerView>
</LinearLayout>
AppointmentListItem.axml:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<TextView
android:text="Name"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/txtName"
android:textColor="#fff"/>
</LinearLayout>
RecyclerAdapter.cs:

public class MyView : RecyclerView.ViewHolder

return view;
}
public override void OnBindViewHolder(RecyclerView.ViewHolder holder, int position)
{
MyView myHolder = holder as MyView;
myHolder.mName.Text = mAppointments[position].Name;
}
public override int ItemCount
{
get { return mAppointments.Count; }
}
}
