单击 RecyclerView 中的项目时，SetOnSlickListener 发生错误。我在单击 ImageButton 时执行了完全相同的设置约束的实现，一切正常，但是当单击该元素时，出现致命错误。我也尝试通过 getChild() 来实现它，但这也没有帮助。有什么问题吗？
您应该发布实际的堆栈跟踪（错误消息和它之后描述导致错误的调用的行）——需要查看大量代码并猜测问题出在哪里。不过，如果我不得不猜测，你会在这里得到它：
setOnClickListener {
...
val constraintSet = ConstraintSet()
val layout = itemView.findViewById<ConstraintLayout>(R.id.card_prices_constraintlayout)
constraintSet.clone(layout)
自从最后一个方法调用在您提供的
getChildCountlayoutpublic void clone(ConstraintLayout constraintLayout) {
int count = constraintLayout.getChildCount();
（我不得不去查找
ConstraintSet所以如果那是你得到错误的地方，你的问题是你的
layoutconstraintLayoutnull上调用
getChildCount()。这意味着您的 findViewByIdcard_type_element.xmlConstraintLayoutcard_prices_constraintlayout
