Greg Shackles and Johnathan Pryor have an article on the subject;
http://mono-for-android.1047100.n5.nabble.com/another-Java-versus-C-how-to-td4332736.html
"C# doesn't allow anonymous implementations like Java (ie: the listener
interfaces) so those get replaced by events/delegates in C#. If you wanted
you could still use the interface since SetItems has a bunch of overloads
[0] but you'd have to define a real class that implements it separately to
use it here. Here's an example of using a lambda to do it:"
var stuff = new string[] { "foo", "bar" };
new AlertDialog.Builder(this)
.SetTitle("Pick something")
.SetItems(stuff, (sender, args) =>
{
Toast
.MakeText(this, stuff[(int)args.Which], ToastLength.Short)
.Show();
})
.Show();
Since you mentioned wanting to avoid the lambda style of nesting the
method, you could define a separate callback method like this:
new AlertDialog.Builder(this)
.SetTitle("Pick something")
.SetItems(stuff, listItemClicked)
.Show();
private void listItemClicked(object sender,
Android.Content.DialogClickEventArgs args)
{
Toast
.MakeText(this, stuff[(int)args.Which], ToastLength.Short)
.Show();
}
