找不到项目视图

Question

inner class ViewHolder(itemView: View) : RecyclerView.ViewHolder(itemView) {
var tvName: TextView = itemView.findViewById(R.id.tvName)
var tvAge: TextView = itemView.findViewById(R.id.tvAge)
var ivProfile: ItemView = itemView.findViewById(R.id.ivProfile)
fun bind(contact: Contact) {
tvName.text = contact.name
tvAge.text = "Age: ${contact.age}"
Glide.with(context).load(contact.imageUrl).into (ivProfile)
}
}
}

科特林只有MenuView.ItemView吗？因为Glide期望ItemView

错误日志：

Type mismatch: inferred type is MenuView.ItemView but ImageView was expected.

如果我粘贴而不是MenuView.ItemViewImageView，那么它会说：

java.lang.ClassCastException: androidx.constraintlayout.widget.ConstraintLayout cannot be cast to android.widget.ImageView

                              at com.jakob.kotlinrecyclerview.ContactAdapter.onCreateViewHolder(ContactAdapter.kt:13)

Answer 1

您应该使用ImageView，而不是ItemView。

对于ClassCastException，检查布局是否具有仅用于ImageView的idivProfile，而不是例如在更高级别的ConstraintLayout中。
