How to use Clickable span?

Hi

Please share some links for using clickable span. I am not getting any solution from internet.

This is for normal Android, but in Xamarin how to use it? Where i should write onclick function of that clickable span?

Android.Text.SpannableString s = new Android.Text.SpannableString("Click here to open activity");

Clickable text is not url, by clicking it will open another activity
