ListPreference中的ArrayIndexOutOfBoundsException

我的Play-Console中有一個奇怪的StackTrace - 我無法重現該問題，它不直接在我的代碼中產生。也許這裏有人有一個關於如何處理這個問題的想法，而不是忽略它。雖然發生過一次 - 但我真的很想知道那裏發生了什麼。ListPreference中的ArrayIndexOutOfBoundsException

請檢查您在ListPref中使用的ArrayList的大小是否有錯誤...？ –

@ligi你是否也可以發佈用於設置列表的偏好設置的XML？ – JJD

我也只在某個設備上面對同樣模糊的異常 - 在所有其他設備上它工作正常。將不勝感激帖子的進展。 – SirKnigget

每當你嘗試訪問是在ArrayList中的範圍（超出大小）或不一般發生java.lang.ArrayIndexOutOfBoundsException:錯誤。

因此，從錯誤中可以看出java.lang.ArrayIndexOutOfBoundsException: length=3; index=3有時會發生這種情況，即您嘗試訪問的數值大於數組的大小。由於您的數組列表只包含總共3條記錄，因爲您可能試圖訪問3位置的索引。而數組開始從索引「0」開始計數它的值，所以會有像0,1,2...這樣的值，所以在這種情況下，它將無法獲得索引「3」處的值不可用。

所以"java.lang.ArrayIndexOutOfBoundsException: length=3; index=3"。這意味着您請求的索引超出了數組的範圍。換句話說，數組有一個長度（這是界限）。當它的長度是3（它是空的）並且你要求第3個元素時，數組告訴你你請求的項目不可用，因爲該數組甚至不是3個元素。
