Abstract
Containers pour a collection of widgets (and possibly child containers) into specific layouts you like. If you want a form with labels on the left and fields on the right, you will need a container. If you want OK and Cancel buttons to be beneath the rest of the form, next to one another, and flush to the right side of the screen, you will need a container. From a pure XML perspective, if you have multiple widgets (beyond RadioButton widgets in a RadioGroup), you will need a container just to have a root element to place the widgets inside.
