Kotlin 中未解决的参考 WearableRecyclerView.Adapter 错误

Question

我正在尝试创建一个带有项目列表的 android wear 应用程序。为了启用循环滚动，我通过在 kotlin 中编码来使用 WearableRecyclerView。但是面对这个错误Unresolved reference: Adapter同样的java代码不会抛出这个错误！我还提到了 kotlin 中的内部类和外部类概念。 Adapter 类是 RecyclerView 的一个抽象类，它又被 WearableRecyclerView 扩展。任何指导都会很有用，谢谢！！

这是我的代码

class CustomRecyclerAdapter(context: Context,dataSet: Array<String>): WearableRecyclerView.Adapter<CustomRecyclerAdapter.viewHolder>() {



var mDataSet: Array<String>
var mcontext: Context


init {
    mDataSet = dataSet
    mcontext=context
}

   inner class viewHolder(view: View) : WearableRecyclerView(mcontext) {

    val mTextView: TextView

    init {
        mTextView = view.findViewById(R.id.textView)
    }

    override fun toString(): String {
        return mTextView.text as String
    }
}

fun onCreateViewHolder(viewGroup: ViewGroup, viewType: Int): viewHolder {
    val view = LayoutInflater.from(viewGroup.context)
            .inflate(R.layout.recycler_row_item, viewGroup, false)

    return viewHolder(view)
}

fun onBindViewHolder(viewHolder: viewHolder, position: Int) {
    // Replaces content of view with correct element from data set
    viewHolder.mTextView.text = mDataSet[position]
}

// Return the size of your dataset (invoked by the layout manager)
fun getItemCount(): Int {
    return mDataSet.size
}

}

Answer 1

与其使用（显然不存在）WearableRecyclerView.Adapter，不如考虑使用不可穿戴适配器：RecyclerView.Adapter

Answer 2

您的课程 inner class viewHolder(view: View) : WearableRecyclerView(mcontext) 必须扩展 WearableRecyclerView.ViewHolder 而不是 WearableRecyclerView 像：

inner class viewHolder(view: View) : WearableRecyclerView.ViewHolder(view)
