To show an Arrow on button, You need to have an Images for the Arrow. Usually when you use Image button, it keeps the background of the button as normal button so you can not have a look and feel like the one you have. The Best option is use ImageView instead of Button or ImageButton and Use Arrow Images to show Arrows.
