작업환경 :
minSdkVersion 8 (Android 2.2 / Froyo)
targetSdkVersion 16 (Android 4.1.2 / IceCream
타겟을 허니컴(3.0) 이상으로 작업 할 때,
이전 버전(.../ 2.2 / 2.3 / 2.3.3 ... )에서 사용하던 기능들 구현방법이 다소 바꼈다.
크게 TabWidget 은 ActionBar 로,
Dialog 는 Fragment 를 이용하여 구현해야 한댄다.
아래 소스는
Dialog 창 띄우는 기능과
AlertDialog (확인 버튼 / 취소 버튼) 기능을 넣은 소스이다.
참고로, 3.0 이하에서도 구현되도록 작성됐음!
