Is it good practice to put same action button in both Action Bar and screen content? Let's say I have following screen structure:
On object list screen user can navigate to the object overview by clicking list item. Following screen contains title, image and some text. At first I only used Action Bar icon to let user go to the detail screen but lately I realized that the icon meaning may not be clear enough for all of the users. So I've decided to put a button inside the screen as well. Now I don't know if I should keep both icon and button or if I should use only the button. Does it matter or I'm just overthinking here?
