A 라는 AlertDialog 와 B 라는 AlertDialog 가 있습니다. 둘다 AlertDialog.Builder 로 생성하였구요,

취하고있는 View 도 둘다 틀리구요. 각각의 View 는 Inflate 하엿습니다.

A 의 Positive 버튼을 누르면 B 의 AlertDialog 가 나오고

B 의 Positive 버튼을 누르면 A 의 AlertDialog 가 나오는 형식을 취하려고 합니다.

그런데 에러가 뜨고 마네요... setPositiveButton 의 onClick 메소드에서 B 의 Alertdialog 를 show() 하였고 B 에서도 마찬가지입니다.

왜그런것일까요?
