Пожалуйста, помогите kotlin ошибка «Для параметра не передано значение»

#kotlin

Вопрос:

У меня есть приложение для чата. Но я получаю такую ошибку в адаптерах. Ошибка: Для параметра «itemView2» не передано значение. Я пытаюсь отобразить элемент с именем itemView2 на странице xml. Я не очень хорошо владею языком Котлин. Вот почему мне нужна помощь.

Это MessagingAdapter.kt

 class MessagingAdapter(private val messages: OrderedRealmCollection<Message>, autoUpdate: Boolean,
                   private val context: Context, private val lifecycleOwner: LifecycleOwner, var user: User, private val myThumbImg: String,
                   private val selectedItems: LiveData<List<Message>>,
                   private val progressMap: LiveData<Map<String, Int>>, private val audibleState: LiveData<Map<String, AudibleState>>)

: RealmRecyclerViewAdapter<Message, RecyclerView.ViewHolder>(messages, autoUpdate)
    , StickyHeaderAdapter<RecyclerView.ViewHolder> {

private val interaction = context as? Interaction?
private val contactHolderInteraction = context as? ContactHolderInteraction?
private val audibleHolderInteraction = context as? AudibleInteraction?

//timestamps to implement the date header
var timestamps = HashMap<Int, Long>()
var lastTimestampPos = 0


//date header
override fun getHeaderId(position: Int): Long {
    return if (timestamps.containsKey(position)) {
        timestamps[position] ?: 0
    } else 0
}

//date header
override fun onCreateHeaderViewHolder(parent: ViewGroup): RecyclerView.ViewHolder? {
    val view = LayoutInflater.from(parent.context).inflate(R.layout.row_day, parent, false)
    return HeaderHolder(view)
}

//date header
override fun onBindHeaderViewHolder(viewholder: RecyclerView.ViewHolder?, position: Int) {
    val mHolder = viewholder as HeaderHolder?

    //if there are no timestamps in this day then hide the header
    //otherwise show it
    val headerId = getHeaderId(position)
    if (headerId == 0L) mHolder?.header?.visibility = View.GONE else {
        val formatted = TimeHelper.getChatTime(headerId)
        mHolder?.header?.text = formatted
    }
}

Это receivedтекстхолдер.kt

 class ReceivedTextHolder(context: Context, itemView: View,itemView2: View) : BaseReceivedHolder(context,itemView) {

private var tvMessageContent: AXEmojiTextView = itemView.findViewById(R.id.tv_message_content)
private val circleImg: CircleImageView = itemView2.findViewById<View>(R.id.voice_circle_img_text) as CircleImageView

override fun bind(message: Message,user: User) {
    super.bind(message,user)
    tvMessageContent.text = message.content
    loadUserPhoto(user,message.fromId, circleImg)
}
private fun loadUserPhoto(user:User,fromId: String, imageView: ImageView) {

    //if it's a group load the user image
    if (user.isGroupBool amp;amp; user.group.users != null) {
        val mUser = ListUtil.getUserById(fromId, user.group.users)
        if (mUser != null amp;amp; mUser.thumbImg != null) {
            Glide.with(context).load(mUser.thumbImg).into(imageView)
        }
    } else {
        if (user.thumbImg != null) Glide.with(context).load(user.thumbImg).into(imageView)
    }
}

}

Пожалуйста, помогите, ребята 🙁 То, что я пытаюсь сделать, это отобразить элемент с именем itemView2 на странице xml.

Ответ №1:

Ошибка означает , что вы пытаетесь вызвать функцию, которая запрашивает имя параметра itemView2 , но вы не передали этот параметр. Обычно это происходит, когда вы предоставляете слишком мало аргументов при вызове метода.

В данном конкретном случае рассматриваемый метод на самом деле является конструктором ReceivedTextHolder . Как вы можете видеть, конструктор объявлен принимающим 3 параметра ( context , itemView , и itemView2 ):

 class ReceivedTextHolder(context: Context, itemView: View,itemView2: View)

Но когда вы вызываете этот конструктор, вы даете только 2 аргумента:

 return ReceivedTextHolder(context, LayoutInflater.from(parent.context).inflate(R.layout.row_received_message_text, parent, false)) //ERROR HERE

Здесь первый аргумент ( context ) получает значение context , а второй аргумент ( itemView ) получает значение выражения:

 LayoutInflater.from(parent.context).inflate(R.layout.row_received_message_text, parent, false)

Но вы упускаете 3-й аргумент. 3-й, вероятно, будет выглядеть как 2-й. Вам просто нужно найти и раздуть правильный вид для этого.

1. Привет @Джоффри, спасибо тебе за помощь. Я попробую это сделать и дам тебе знать. Я надеюсь, что смогу. 🙂
