잘한다면? Java는 이와 같은 혼합 유형의 목록을 허용하지 않습니다. 내가 생각할 수있는 유일한 방법은 항목을'Object'로 추가 한 다음 목록에서 항목을 액세스 할 때'instanceof'를 사용하여 캐스트하는 것입니다. 또 다른 옵션은 정수를 두 배로 변환하는 것입니다. 네가 묻고있는거야? – NoChinDeluxe

'ArrayList '이 효과가 있습니까? 또한, 어느 선이 오는 오류입니까? – 4castle

구문 분석에서 해당 데이터를 가져오고 작업하는 사람들은 그와 같은 데이터를 가지며 파싱 dosent는 소수점 이하의 추가 0을 허용합니다. 가져온 데이터가 arraylist 형식 인 – B0rn2C0de

이 감사를 통해 주변에있다. threatlevel = (double) items.get(position);

동시에 문제는 캐스팅과 오토 복을 원하지 않는 것으로 보입니다. 모두 Double 및 Integer이 Number을 확장 때문에, 당신은 사용할 수 있습니다 : 목록이` ArrayList에`왜 당신이 그것으로 정수를 넣어 시도로 선언

threatlevel = items.get(position).doubleValue();

java.lang.Integer는 java.lang.Double에 캐스팅 될 수 없습니다
