/*
LayoutInflater 클래스의 inflate메소드는 xml로 정의된 Layout을 View로 전개할 때 사용하며 정의된
layout xml의 resouce의 id를 함수 파라메터로 전달하면 전개된 View를 리턴한다.
전개할 View를 root에 붙일지에 따라 호출하는 파라메터가 달라지는데 root에 붙이지 않고
전개된 View만 얻고 싶을 때는 아래 두 가지 코드를 이용 할 수 있다.
View view = inflater.inflate(R.layout.layout_xxxx, null);
View view = inflater.inflate(R.layout.layout_xxxx, root, false);
첫번째 코드는 동작은 하지만 View를 전개할 때 참고할 parameter 정보가 없어 경고가 발생된다.
Avoid passing null as the view root
(needed to resolve layout parameters on the inflated layout's root element)
두번 째 샘플은 두번째 파라메터로 전달된 root의 레이아웃의 파라메터 정보를
참고해서 View를 전개하고 마지막 파라메터가 false이므로 root에 붙이지 않는다.
물론 경고도 발생하지 않는다.
전개된 View를 root에 attach하기
전개와 동시에 root에 붙이고 싶다면 아래 샘플 중에서 하나를 선택해서 사용한다.
View view = inflater.inflate(R.layout.layout_xxxx, root);
View view = inflater.inflate(R.layout.layout_xxxx, root, true);
Android 소스를 보면 inflate(int, ViewGoup)은 inflate(int, ViewGroup, boolean) 함수를 호출하므로 결과는 동일하다.
View inflate(int resource, ViewGroup root) {
return inflate(resource, root, root != null);
