android - Kotlin中 Unresolved reference WearableRecyclerView.Adapter错误

我正在尝试创建带有项目列表的android wear应用。为了启用循环滚动，我通过在kotlin中进行编码来使用WearableRecyclerView。但是面对此错误 Unresolved reference :适配器 java中的相同代码不会引发此错误!我还提到了kotlin中的内部和外部类概念。适配器类是RecyclerView的抽象类，而WearableRecyclerView又对其进行了扩展。任何指导将很有用，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
}

}

最佳答案

您的类inner class viewHolder(view: View) : WearableRecyclerView(mcontext)必须扩展WearableRecyclerView.ViewHolder而不是WearableRecyclerView，例如:

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