Hi Xamaranians,
I regularly get an unhandled exception in the emulator when I instantiate a
custom ArrayAdaptor. The top level of the call stack shows:
"Mono_UnhandledException":
System.Diagnostics.Debugger.Mono_UnhandledException (Parameters=) in
/home/jon/Development/xamarin/mono/mcs/class/corlib/System.Diagnostics/Debug
ger.cs:124
The line of code is:
var adapter = new CustomisedTypefaceArrayAdapter<String>
(_registry.CustomTypeface, this, Resource.Layout.list_item, suggestions);
The stacktrace is:
I/mono ( 8244): Stacktrace:

The class being instantiated is:
public class CustomisedTypefaceArrayAdapter<T> : ArrayAdapter<T>
{
Typeface _typeface;
public CustomisedTypefaceArrayAdapter (Typeface typeface, Context context,
int textViewResourceId, IList<T> objects)
: base(context, textViewResourceId, objects)
{
_typeface = typeface;
}
public override View GetView (int position, View convertView, ViewGroup
parent)
{
View v = base.GetView (position, convertView, parent);
if (v is TextView)
{
((TextView)v).SetTypeface (_typeface, 0);
}
return v;
}
}
I thought I'd post it, since I also get the stack traceless exception on my
device and I thought it might be related.
