问题
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.
回答1:
Just put this in your button.onClick
spinner.performClick();
回答2:
Define a spinner in your activity with 0 height and 0 width in your xml, then the onItemSelected will work
