Android 항목 오버레이! 지도에 마커를 배치하고 제거하십시오.

Question

사용자의 현재 위치를 표시하고 사용자가지도에 하나의 마커를 배치 할 수있게하려고합니다. 사용자가 마커를 두드리면 마커가 사라지고지도에 다른 마커를 다시 놓을 수 있습니다.

다음 코드는 사용자의 현재 위치를 표시하고지도에 하나의 표식을 배치하는 데 적합합니다. 또한 마커를 제거 할 수 있습니다. 하지만 일단 마커를 제거한 후에지도에 다시 놓으려고했습니다. 프로그램이 추락했습니다! 아무도 그 이유를 말해 줄 수 있습니까? 일식에서

Answer 1

변화 당신이 보호 부울 ONTAP에 (INT 지수)이를 추가하여 탭 항목을 제거하는 방법 :

   mOverlays.remove(index); 
       setLastFocusedIndex(-1); 
       map.invalidate(); 

그것은 해결됩니다 너의 문제.

사실, ItemizedOverlay 및 OverlayItem 클래스의 디자인이 좋지 않다고 생각하는 유일한 사람입니까?
