当edittext更新时，如何在片段的recyclerview中更新textview？

Question

每当我更改编辑文本之一时，我都会尝试更新我的回收站 itemViews。 例如，如果我的 edittext 说 C20 用于 cheetos（其中 C20 是 eduttext 而 cheetos 是 textView），如果我将其更改为 L20，我希望更新我的 textviews。 我尝试了以下不起作用的方法，我的数据集已更改，但视图未更新。 我在这里错过了什么吗？ 在下面附上我的 rcv 适配器。

请查看 updateStockDetail function。

class RecyclerViewAdapterU (val dataList:ArrayList<ModelClass>): RecyclerView.Adapter<RecyclerViewAdapterU.ViewHolder>() {
var _binding: UploadItemViewBinding? = null
val binding get() = _binding!!
override fun onCreateViewHolder(
    parent: ViewGroup,
    viewType: Int
): RecyclerViewAdapterU.ViewHolder {

    val v =
        LayoutInflater.from(parent.context).inflate(R.layout.upload_item_view, parent, false)
    _binding = UploadItemViewBinding.bind(v)
    return ViewHolder(binding.root)
}


override fun onBindViewHolder(holder: ViewHolder, @SuppressLint("RecyclerView") position: Int) {


    bindItems(dataList[position])
    holder.getStock()
    holder.updateStockDetail()

}
fun bindItems(data: ModelClass) {

    binding.itemquant.text = data.item_quant
    binding.uploadItemName.text = data.item_name
    binding.uploadMfg.text = data.mfg
    binding.skuStock.setText(data.item_stock.toString())
    binding.skuCode.setText(data.sku_code)
}


override fun getItemCount(): Int {
    return dataList.size
}


inner class ViewHolder(itemView: View) : RecyclerView.ViewHolder(itemView) {
    var stockdetail = ArrayList<ModelClass>()

    fun getStock() {

        binding.skuStock.addTextChangedListener(object : TextWatcher {
            override fun beforeTextChanged(charSequence: CharSequence, i: Int, i1: Int, i2: Int) {}
            override fun onTextChanged(charSequence: CharSequence, i: Int, i1: Int, i2: Int) {}
            override fun afterTextChanged(editable: Editable) {
                for (i in 0 until RecyclerViewAdapter.ob.dataSelected.size){
                    if (editable.toString().trim()!=""){
                        var x= editable.toString().trim().toInt()
                        RecyclerViewAdapter.ob.dataSelected[adapterPosition].item_stock=x
                    }
                }


            }

        })
    }

    fun updateStockDetail(){
        binding.skuCode.addTextChangedListener(object : TextWatcher{
            override fun beforeTextChanged(charSequence: CharSequence, i: Int, i1: Int, i2: Int) {}
            override fun onTextChanged(charSequence: CharSequence, i: Int, i1: Int, i2: Int) {


            }
            override fun afterTextChanged(editable: Editable) {
                if (editable.length==3){

                var x:String
                for (i in 0 until RecyclerViewAdapter.ob.dataSelected.size){
                    if (editable.toString().trim()!=""){
                        x=editable.toString().trim()
                        RecyclerViewAdapter.ob.dataSelected[adapterPosition].sku_code=x
                        println("$x in if")

                    }
                }
                println(RecyclerViewAdapter.ob.dataSelected[adapterPosition].sku_code)
                getUpdatedDetails(RecyclerViewAdapter.ob.dataSelected[adapterPosition].sku_code)
                    for (i in stockdetail){
                        bindItems(i)   //doesnt reflect on itemview in recycler
                        println(i.item_name)
                    }
            }}

        })
    }


    fun getUpdatedDetails(skucode:String){
        val call: Call<List<ModelClass>>? =
            ApiClient.instance?.myApi?.getfromsku(skucode)!!
        call!!.enqueue(object : Callback<List<ModelClass>?> {
            override fun onResponse(
                call: Call<List<ModelClass>?>,
                response: Response<List<ModelClass>?>
            ) {
                val skuDetails=response.body()

                stockdetail.clear()
                if (skuDetails != null) {
                    for (i in skuDetails){
                        println(i.item_name)
                        stockdetail.addAll(skuDetails)
                    }
                }
            }

            override fun onFailure(call: Call<List<ModelClass>?>, t: Throwable) {
                TODO("Not yet implemented")
            }
        })


    }



}

如果我将“b20”更改为“c20”，我希望 c20 的数据反映在 itemview 中。

更新项目数据后调用notifyDataSetChanged 。
