You are absolutely right. When I removed the setBackgroundColor() the Spinner did display a drop-down button. My app still had an option to change the background color and when that button was clicked it changed the background color and the drop-down arrow also disappeared. Who would have thought. I was changing the background as an exercise in learning the capability of all the widgets. Thank you for your answer, it was driving me nuts.
