Every Button is styled using the system's default button background, which is often different from one device to another and from one version of the platform to another. If you're not satisfied with the default button style and want to customize it to match the design of your application, then you can replace the button's background image with a state list drawable. A state list drawable is a drawable resource defined in XML that changes its image based on the current state of the button. Once you've defined a state list drawable in XML, you can apply it to your Button with the android:background attribute.

RelativeLayout is a view group that displays child views in relative positions. The position of each view can be specified as relative to sibling elements (such as to the left-of or below another view) or in positions relative to the parent RelativeLayout area (such as aligned to the bottom, left or center).
