java.lang.ClassCastException: androidx.appcompat.widget.AppCompatImageView 不能转换为 android.widget.TextView

Question

启动我的活动时，我不断收到运行时错误，它说 androidx.appcompat.widget.AppCompatImageView 不能转换为 android.widget.TextView？

我也试图清理项目重新构建它。 但这也行不通。 我无法理解项目中会产生什么问题。

如果没有看到您的 homeAdapter 类，很难说。 无论如何，这是由错误的ID引起的。
