Custom AlertDialog 구현하기.

설.현.아빠 2011. 7. 11. 16:56

CustomAlertDialog를 구현해 보았다.

AlertDIalog에 들어가는 버튼은 addButton 함수를 이용해서 계속 추가시킬 수 있도록 하였다.

즉, Activity마다 각자 AlertDialog를 구현하지 않고, CustomAlertDialog 를 계속해서 사용할 수 있는 것이다.

이때 CustomAlertDialog에는 interface를 구현해 두어 각각의 Activity에서 각자의 Button Control이 가능하도록 하였다.

interface를 사용하는 방법에 대해서는 두개의 Activity가 다른 방식을 사용해 보았다.

아래 예제가 있다^^
