This is my xml I used:

Answer 1

Inspired by Gustavo's answer, here is my version of Spinner's background with DropDown arrow. Just the complete background, not only the arrow.

This is how it looks

Apply on spinner like

spinner_bg.xml

@color/InputBg should be replaced by the color you want as your background.

First it fills the background with desired color. Then a child layer-list makes a square and rotates it by 45 degrees and then a second Rectangle with background color covers the top part of rotated square making it look like a down arrow. (There is an extra stroke in rotated rectangle with is not really required)
