사용자 정의 OnTouch
구현을 사용하여 ViewFlipper
을 사용하는 응용 프로그램을 개발 중입니다. ViewFlipper
에는 사용자가 넘기도록 약 20 개의 이미지가 있습니다. 이것은 잘 작동하지만 시리즈의 20 번째 이미지에서 화면을 넘길 경우 첫 번째 이미지로 돌아갑니다.ViewFlipper가 루핑되는 것을 방지하는 방법
ViewFlipper
이 첫 번째 이미지로 돌아 가지 않게하고 싶습니다. 대신 마지막 이미지에서 멈춰야합니다.

화면을 뒤집어서 무엇을 의미하는지 자세히 설명해 주시겠습니까? 방향 변경이나 'ViewFlipper'에서 일종의 슬쩍 제스처를하는 것에 대해 이야기하고 있습니까? 표시 할 수있는 동작을 생성하는 코드가 있습니까? – nil
위의 qestion에서 확인할 수있는 질문에 내 코드를 추가 할 수 있습니다. –
