When to apply an onClickListener?

Author	Message
lbriggs Posts: 57	Posted 16:41 Apr 26, 2014 \| So I got my Swipe app working, but I had to hack it together a bit. I am setting an onClickListener to detect the swipe. To set the onClickListener I first have to find the widgets ID, then apply the listner. But when I try this on the Activities onCreate() method the find call returns null. I have to set it on another function that gets called after the view gets drawn (an onClick() method of an imageView). Is there a way I can call this on the onCreate() or onResume() method instead of this onClick method? Thanks
