Only speculate your layout problem
android: layout_width = "match_parent"
android: layout_height = "match_parent"
android: paddingBottom = "@ dimen / activity_vertical_margin"
android: paddingLeft = "@ dimen / activity_horizontal_margin"
android: paddingRight = "@ dimen / activity_horizontal_margin"
android: paddingTop = "@ dimen / activity_vertical_margin"
