요구 사항 : 버튼을 1 초 이상 누르고있는 경우에만 itemLookup이 수행되어야합니다. 단추를 3 초 동안 누르고 있으면 조회에 사용 된 녹음에 불필요한 데이터가 포함되지 않도록 단추 이벤트를 중지하십시오.Android : 트리거링 MotionEvent.ACTION_CANCEL

OnTouchListener이벤트라고 예상대로TableLayoutForIntercept, 'MainActivity가 이전의onInterceptTouchEvent가 호출되는'것을 확인하더라도MotionEvent.ACTION_CANCEL가 호출되지 않습니다. 아마도onInterceptTouchEvent의 목적을 이해하지 못했을까요? 이 문제에 대한 다른 게시물을 살펴 보았지만 모두 스 와이프 또는 드래그 이벤트가 아닌 버튼을 취소하는 이벤트를 처리하고 있습니다. 아마 이것은 할 수 없습니까? 코드 : 해당
