android - ListPreference 中的 ArrayIndexOutOfBoundsException

Question

我的 Play-Console 中有一个奇怪的 StackTrace - 我无法重现该问题，它并非直接源于我的代码。也许这里有人对如何处理这个问题有想法，而不仅仅是忽略它。虽然只发生过一次 - 但我真的很想知道那里发生了什么。

java.lang.ArrayIndexOutOfBoundsException: length=3; index=3

我假设您正在使用 PreferenceActivity 或 PreferenceFragment(Compat)

在您的首选项 xml 文件中定义 ListPreference 参数时，您似乎遗漏了一些东西，我认为您的 android:entries 和 android:entryValues 大小不匹配。
