我收到了以下错误消息java.lang.ArrayIndexOutOfBoundsException: length=1; index=1 at com.sbeyer.daainv.EditDataFragment.onCreateView(EditDataFragment.java:110)我知道这个错误表明我的数组只包含[0]值。但是我片段中的Log.d消息给了我这个日志：

你看我的数组不是空的......还有其他的东西，比如将值设置为EditTexts，工作正常。但是，如果我点击fabmain错误发生（我的DBHelper类中调用的每个方法也正常工作。更改会保存，但我的应用程序会崩溃。有人可以帮助我吗？

似乎onCreateView方法运行了两次。但我无法弄清楚原因。

如果我加载数组一切都很好（请参阅上面的Log.d条目）dataLength: 9我点击我的按钮后我从该位置获得另一个Log.d条目dataLength: 1为什么我的片段和＃34;重建＆＃34;本身？
答案 0 :(得分：2)
错误说length=1; index=1。这意味着，您的数组不是空的，有一个项目，但您尝试获取第二个项目。数组以0索引开头，而不是1.这就是问题。
答案 1 :(得分：0)
问题解决了。片段管理器在加载另一个片段时出现问题。
