Thanks for logging the bug, Jon. I went ahead and used ArrayAdapter<String>. Then for my DeviceList, I created this extension method that just takes the value I wanted to display as a string in my list.
// Extension method
public static String[] Names(this DeviceList inList)
{
string[] deviceList = new string[inList.count];
for (int i = 0; i < inList.count; i++)
{
deviceList[i] = inList.Devices[i].DeviceName;
}
return deviceList;
}
Then here is the first part of my DeviceArrayAdapter where you see what I did.
public class DeviceNameArrayAdapter : ArrayAdapter<String>
{
DeviceList _DeviceList;
private int mResID;
public DeviceNameArrayAdapter(Context c, int resID, DeviceList inDeviceList)
: base(c, resID, inDeviceList.Names())
{
mResID = resID;
_DeviceList = inDeviceList;
}
....
It seems to be a good workaround for me, so I thought I would share it.
