Question

我收到错误“您的应用程序正在使用PreferenceActivity类的不安全实现，这使得它们容易受到碎片注入的影响。”来自Google Play。

我已阅读https://support.google.com/faqs/answer/7188427?hl=en和Your implementation of PreferenceActivity is vulnerable to fragment injection

是否意味着PreferenceActivity类已经过时了？我该如何解决这个问题？

首选添加首选项的方法是在正常活动中使用首选项片段。使用框架布局创建常规活动并创建首选项片段，该片段将使用首选项屏幕显示首选项。见https://developer.android.com/guide/topics/ui/settings.html#Fragment
