You are supposed to specify the color you want to set to the background. It should be a integer value so if you have HEX value convert it to integer using Color.parseColor method to convert it to integer and then set inside those paranthesis

Yes, but in android studio auto complete gives me this: 

image.setBackground(Drawable background)

Thats alright. Just delete that and insert your integer value and try.

I'm trying to set a background image not a background color.

winner.setBackground(Color.WHITE); // This  does not work because .setBackground() is asking for a drawable image!

winner.setBackgroundColor(Color.WHITE); // this is the way to set a Background Color

pathName = "/drawable/img1"
winner.setBackground(Drawable.createFromPath(pathName));

Only problem now is the path name! The Java file and the activity.xml file are in completely different folders!
