CollapsingToolBarLayout 无法实例化

在过去的几个月里，我一直在使用折叠工具栏布局，没有任何问题。然而今天，每当我打开 xml 文件时都会弹出此错误。确切的错误如下：

以下类无法实例化： - android.support.design.widget.CollapsingToolbarLayout

这是堆栈跟踪：

在模拟器中运行应用程序后，工具栏工作得很好，但我仍然很困惑为什么在 android studio 中会发生这种情况。我已经清除了缓存、重建、重新检查了支持库版本以及我能想到的所有其他内容。我缺少什么？

Remove

app:collapsedTitleTextAppearance="@color/black

相反，要更改标题颜色，请使用此处描述的方法之一：

还要更新您的 Android 支持库24.2.1版本。
