伙计们！我遇到了一个问题。我正在使用支持首选项倾斜库来显示设置。

在某些情况下，我还需要在移动设备上显示后仰设置，并且在Lollipop 之前的设备上，片段在使用此堆栈跟踪时因膨胀而崩溃：

没有人知道，“在 android.view.Vie”之后会发生什么，但我已经本地化了问题，那是因为移动设备找不到PreferenceCategory类/布局。如果我从preferences.xml 文件中删除PreferenceCategories - 一切正常。

还添加了支持首选项库，但这并没有解决问题。

你有什么想法，为什么会发生这种情况？

PS：如果您需要更多信息 - 我会添加更多来源并回答所有问题。

非常感谢！
