/**

/**

 * MATCH_PARENT means that the view wants to be as big as its parent,

 * minus the parent's padding, if any. Introduced in API Level 8.

 public static final int MATCH_PARENT = -1;

FILL_PARENT와 MATCH_PARENT는 정의된 값이 -1로 같다.

FILL_PARENT는 API8 부터 deprecated가 된다. 하위 호환을 위해 FILL_PARENT가 남았있는 것이고 가독성과 일관성이 있는 MATCH_PARENT 가 앞으로 사용될 예정이다.
