나는 안드로이드에있어 초보자입니다. 내 응용 프로그램에서 ArrayIndexOutOfBoundsException이 발생하는 경우가 있습니다. 그러나 나는 그것을 재현 할 수 없다. 그 누구도 날이 예외 로그 캣arraylist에 대한 ArrayIndexOutOfBoundsException 처리 방법

이며,이에 대한 샘플 응답입니다 수 서버의 arraylist

내가 응답로 받고 있어요 (7-1 = 6로 dayIndex을 줄 것이다) 일요일에서 이러한 예외를 받고 있어요

[ArrayIndexOutOfBoundsException이 발생하는 이유는 무엇이며 Android에서이를 피하는 방법은 무엇입니까?] (http://stackoverflow.com/questions/4958235/why-does-arrayindexoutofboundsexception-occur-and-how-to) -avoid-it-in-android) –
배열 인덱스는 0부터 시작합니다. 많은 코드를 작성하기 전에 Java 개념을 수정해야합니다. o – Debdeep
기본적으로 List에는 적어도 요일만큼의 항목이 있어야하며 그렇지 않은 경우가 있습니다. 목록에 6 개의 항목 만 있기 때문에 경계 밖에서 마지막 주를 잡으려고 할 때. 따라서 서버에서 가져온 데이터에 문제가 있습니다. 또는 "시간"목록을 올바르게 작성하지 않아도됩니다. – Eselfar
