Since you provided woefully incomplete information. we have to guess. You
shouldn't be shouting at me for that. You never said anyhthing about
casting a 'String[]' because you didn't say what type 'bar' is. So get off
your bloody high horse, bubba.
Since you didn't tell us at all yet, what is the type of 'bar'?

Boy, you love to be rude, don't you?
Do you think a smiley makes your comment less obnoxious?
I ask again, what was the type of 'bar'?
You cop all this attitude, bu you leave out the vital datum.

Yes, you said and quoted again, "A simple switch() in onItemClicked will
determine which type of settings are in effect".
What kind of "type" did you mean?
