• A viewgroup can be something like LinearLayout, or FrameLayout
• Otherwise known as Layouts and Layout Managers
• layout_* is an attribute in a view that communicates to the parent viewgroup how it wants to be layed out.
  • layout_width
  • layout_height
  • can be in px, in, mm, dp, match_parent, or wrap_content
  • layout_weight can give each item a proportion of how big it'll be, in a LinearLayout. GridLayout is similar but in 2 dimensions.
  • RelativeLayout is my preferred layout. You describe it's position relative to another.
  • FrameLayout is for any dynamically added object (fragments or widgets)
