다른보기를 포함하면 Google지도가 작동하지 않습니다.

Question

사용자 정의보기를 만들고 fragment.but 내부에 포함 시키십시오.지도 터치가 작동하지 않습니다. 왜곡 된보기는 warp_content를 수행 한 후 화면의 전체 해상도를 얻습니다. Google지도 위의 크기 조정 가능한 사각형을 그릴 때지도 터치가 작동하지 않습니다. 이 기본 활동 XML에서이 직사각형보기를 포함 할 곳을 지정합니다. 나에게 어떤 생각이 든주세요. "com.My-application.activities.rectangle"은이 클래스를 추가하는 패키지입니다. 실제로 나는 스크롤과 사각형 같은 시간 맵을 작업하고 싶습니다. 내 문제를 해결할 수있는 적절한 접근 방식을 권해주십시오.

미리 감사드립니다.

Answer 1

내부 메서드 onTouch false를 반환합니다. 체계에, 그 접촉은 파견되지 않았다는 것을 말한다. 의사 코드 :

if (rectangleTouched) 
    return true; 
else return false; 

Android docs에서

부울 onTouchEvent (MotionEvent 이벤트)

결과 : 부울 참 이벤트가 처리 된 경우, 그렇지 않은 경우는 false.
