how do I change the style of a button in android?

Question

I want to change the style of a button in an android app. here is a picture that has both kinds of buttons, the one that I have now, and the one that I want to switch to:

the kinds of buttons that I am using now, look like any of the letters on that keyboard. the ones that I want to use like like the arrows. I would I go about changing this. I prefer to do it in xml but I can do it in java if that is the only way. Thanks

change the background of the Button to a png image with arrows! in XML use android:background="@drawable/yourimage"
