Hopefully a Googler will correct the mess I may make with this reply... Any time you see an attribute in layout XML that begins with android:layout_, ignore the widget class (in your case, Button). Those attributes are layout parameters (hence, the layout_ prefix) and they are documented on the container class, not on the widget class. Your list of attributes shown above appears to be from a widget that is a child of a RelativeLayout. If you look at the RelativeLayout.LayoutParams documentation: http://tinyurl.com/2bsw97 You will see that: -- android:layout_below and android:layout_alignParentRight belong to RelativeLayout.LayoutParams -- android:layout_marginTop and android:layout_marginRight belong to the ViewGroup.MarginLayoutParams superclass -- android:layout_width and android:layout_height belong to the ViewGroup.LayoutParams superclass Layout XML attributes that do not begin with android:layout_ are (usually) attributes of the widget itself and should be documented on the widget class or one of its superclasses. I've made a note to add an appendix to my book that maps out what all these layout XML attributes belong to. -- Mark Murphy (a Commons Guy) http://commonsware.com Android Training on the Ranch in September! http://www.bignerdranch.com --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Android Beginners" group.
