Set selected item of spinner programmatically

I am working on an android project and I am using a spinner which uses an array adapter which is populated from the database. I can't find out how I can set the selected item programmatically from the list. For example if, in the spinner I have the following items: - Category 1 - Category 2 - Category 3 How would I programmatically make Category 2 the selected item when the screen is created. I was thinking it might be similar to c# I.E Spinner.SelectedText = "Category 2" but there doesn't seem to be any method similar to this for Android.
