当我将 AppcompatActivity 扩展为超类时，除了抽象类 MaterialSettings 的 addItem 之外，错误将被删除。

当我将 MaterialSettings 扩展为超类时，会产生上述错误。

我正在 Android 中设计一个设置页面。还尝试了外部工具中的 javah，并将 appcompact 的最新版本更改为 28.+ 和 27.1.1，但仍然没有解决错误。

请指导我在哪里以及需要更新或更改的内容。

Answer 1

Material Settings 是一个从ActionBarActivity 扩展而来的第三方库。但是，ActionBarActivity 已弃用，不应再使用。为了在您的活动中支持操作栏，您应该从AppCompatActivity 扩展。

我建议不要为此目的使用第 3 方、未维护的库。相反，实现您自己的设置屏幕。如果你不知道怎么做，你可以在网上找到很多教程。这里有一个供您参考：https://medium.com/@JakobUlbrich/building-a-settings-screen-for-android-part-1-5959aa49337c
