I have been able to customize the action bar’s background, logo image and text color using suggestions from these:
Android: How to change the ActionBar “Home” Icon to be something other than the app icon?
ActionBar text color
ActionBar background image
The last piece I want to customize is the back button image. It’s grey by default and I would like it to be white. Either changing the color, specifying a drawable or simply making it transparent (and adding the chevron to my customized logo image) would work. How do I go about that?
