How can I make the spinner width same as largest available item width

Question

I realize even I use wrap_content for my spinner (I avoid using match_parent as I do not want the spinner overly long), and using match_parent

Answer 1

You should be able to get the effect you want by specifying the width of the dropdown as WRAP_CONTENT:

This will measure up to 15 items in the spinner's adapter to determine the width it should use.
