Android OPEN spinner with single button click

Question

I have implemented button which clicks and opens dialog with spinner inside as described here

However this is two clicks. One to open dialog and one to open spinner. I want the spinner to open with a single click of the button? How can this be done?

Is there anyway to just open spinner from button click w/o going to dialog. If not how can I open dialog view and have the spinner open at same time.

Answer 1

Just put this in your button.onClick

spinner.performClick();
