위에 코드는 뷰 플립퍼의 끝과 끝을 정의한 것.

소스에서는 interface로 정의한 상수 부분이 빠져있다. interface를 활용한 상수 부분을 참고.

뷰 플리퍼의 레이아웃은 <include>를 레이아웃 xml에 정의하여 사용하고

각 액티비티의 LinearLayout은 id를 부여하여 다음과 같이 버튼을 만든다.

LinearLayout linear = new LinearLayout();
Button btnTest = (Button) linear.findViewById(R.id.testButton);

context를 받아와서는 getClass()를 한 뒤 equal 비교
