Description

When the user opens the Picker on Android it will show an alert dialog with the options to select but it's not showing the currently selected option. I think this is a UX issue given that if the dialog covers the picker EditText then the user needs to cancel the action to check what was currently selected.
I think the problem is that on the PickerHandler.Android implementation SetItems is being used as you can see here but in my opinion SetSingleChoiceItems should be used which would enrich the dialog displaying the current selected option.
I guess something like this should work:

builder.SetSingleChoiceItems(items, VirtualView.SelectedIndex, (s, e) =>
{
	var selectedIndex = e.Which;
	VirtualView.SelectedIndex = selectedIndex;
	base.PlatformView?.UpdatePicker(VirtualView);
});

If the change can't directly be added because is a change in current UI/UX behavior and everyone may not be in favor of this, could a Mode be added there so we can choose how to show the items?

Steps to Reproduce

Just add a Picker to some page with options to select.

Is this a regression from previous behavior?

Yes, this used to work in Xamarin.Forms on the non-AppCompat version but using a NumberPicker which IMO is not ideal.
