android - 如何在回收站 View 中获取某些编辑文本的值(value)？

Question

我在回收站 View 中有一些项目，每个项目都有一个编辑文本，我如何从每个编辑文本中获取值并将其传递给前一个 fragment ，我尝试了一些解决方案，但它们都不适合我。
这是我的适配器:

interface OnUpdateData{
    fun dataUpdate (data: List<AcceptanceDifferent>?)
}

class EditAcceptDifferentAdapter(private val itemAcceptance: List<DistributionPlanItems>,
                                 private val action: OnUpdateData) :
    RecyclerView.Adapter<EditAcceptDifferentAdapter.MainViewHolder>() {

    private var selectedItem  = mutableSetOf<AcceptanceDifferent>()
    private val selectedId = mutableSetOf<Int>()
    private lateinit var listData: ArrayList<AcceptanceDifferent>

    override fun onCreateViewHolder(
        parent: ViewGroup,
        viewType: Int
    ): MainViewHolder {
        return MainViewHolder(
            LayoutInflater.from(parent.context)
                .inflate(R.layout.list_edit_different, parent, false)
        )
    }

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

    @SuppressLint("SetTextI18n")
    override fun onBindViewHolder(holder: MainViewHolder,position: Int) {
        val items = itemAcceptance[position]
        if (!items.expiredDate.isNullOrEmpty()) {
            val format2 = "yyyy-MM-dd"
            val localeID = Locale("in", "ID")
            val simpleDateFormat2 = SimpleDateFormat(format2, localeID)
            val date = simpleDateFormat2.parse(items.expiredDate)
            holder.expiredDate.text = "Expired Date: ${simpleDateFormat2.format(date)}"
        }

        holder.batchCode.text = "Batch Code: ${items.inventory?.batchCode}"
        holder.medName.text = items.medicine?.name
        holder.batchCode.text = items.inventory?.batchCode
        listData = ArrayList()

        listData.add(AcceptanceDifferent(id = items.distPlanItemId, actualReceivedPackageQuantity = 0))
        action.dataUpdate(listData)

    }


    inner class MainViewHolder(val view: View) : RecyclerView.ViewHolder(view) {
        val medName = view.textMedName1
        val batchCode = view.tvBatchCode
        val expiredDate = view.textMedExpiredDate1
        val qty = view.editTextQty
    }


}

我已经制作了一个接口(interface)来传递数据，但在我的代码中，它不起作用

谢谢你

您必须注意 EditText 中更改的文本并在那里进行操作，然后通知监听器检查数据。检查以下实现。希望这会帮助你。

// You have to initialize listData outside of onBindViewHolder
listData = ArrayList()

@SuppressLint("SetTextI18n")
override fun onBindViewHolder(holder: MainViewHolder,position: Int) {
    val items = itemAcceptance[position]

    // Other code here

    holder.batchCode.text = "Batch Code: ${items.inventory?.batchCode}"
    holder.medName.text = items.medicine?.name
    holder.batchCode.text = items.inventory?.batchCode
    //listData = ArrayList()    

    holder.qty.doAfterTextChanged { text ->
        val data = listData.find { it.id == items.distPlanItemId }
        val value = text?.toString()?.toInt()

        if(data == null) {
            listData.add(AcceptanceDifferent(id = items.distPlanItemId, actualReceivedPackageQuantity = value))
        } else {
            data.actualReceivedPackageQuantity = value
        }

        action.dataUpdate(listData)
    }
}
