Hi, Well, first of all RelativeLayout ignores layout_gravity. Then you need to know that gravity means "apply gravity to the content of this view" whereas layout_gravity means "apply gravity to this view within its parent." So on a TextView, gravity will align the text within the bounds of the TextView whereas layout_gravity will align the TextView within the bounds of its parent.
