android - 如何避免recyclerview item cast错误

Question

努力寻找解决方案来解决我在 viewHolder 中单击 itemView 时遇到的转换错误。

ViewHolder 有一个 constraintLayout 和 3 个 textviews，并为 textviews 实现 onClickListeners，其中 2 个工作正常，但连接到 constraintLayout 的那个会给出异常 onClick->

java.lang.ClassCastException: android.widget.FrameLayout$LayoutParams cannot be cast to android.support.constraint.ConstraintLayout$LayoutParams

在适配器中投射 layoutParams 的正确位置在哪里，或者我应该使用 frameLayout 吗？

java.lang.ClassCastException: android.widget.FrameLayout$LayoutParams cannot be cast to android.support.constraint.ConstraintLayout$LayoutParams
