Widgets can have margins //. As with CSS, // margins provide separation // between a
widget and anything adjacent to it (e.g., other widgets, edges of the screen). // Margins
are really designed // to help prevent widgets // from running right up next to each other,
// so they are visually distinct. // Some developers, however, // try to use margins as a way
to hack // “absolute positioning” into Android, // which is an anti-pattern that we will
examine later in this chapter.
