android - 如何在 RecyclerView 中更新多个文档

Question

我正在尝试更新从 fileManager 中选择的文档，我已将列表中的所有文档显示为recycler view.

  override fun onBindViewHolder(holder: IndianPatientFormSixViewHolder, position: Int) {

    val docs = viewModel?.patientDocumentList?.get(position)

    if(viewModel?.positionOfDocumentSubmittedList?.isNotEmpty() == true){

        val submittedDocPosition = viewModel?.positionOfDocumentSubmittedList?.get(position)

        if(submittedDocPosition == position){
            holder.docUploadedText.visibility = View.VISIBLE
        } else {
            holder.docUploadedText.visibility = View.GONE
        }
    } else {
        holder.docUploadedText.visibility = View.GONE
    }

    holder.certificateNameTextView.text = docs?.label

    holder.uploadImage.setOnClickListener {
        indianPatientFormSixCallback?.onUploadButtonClicked(position,itemId = docs?.doc_id ?: 0)
    }

}

以上是我的代码

我有两个列表patientDocumentList，它们来自具有文档列表的 API，并且我已经为选定的文档位置定义了positionOfDocumentSubmittedList。

如果我在更新回收站视图的位置时单击文档列表的第二位置，则会出现以下错误：

我还附上了更新的回收站视图的屏幕截图。

Answer 1

val listSize = viewModel?.positionOfDocumentSubmittedList

if(viewModel?.positionOfDocumentSubmittedList?.isNotEmpty() == true){

    for (i in 0 until listSize!!.size) {

        val submittedDocPosition = viewModel?.positionOfDocumentSubmittedList?.get(position)
        if (submittedDocPosition == position) {
            holder.docUploadedText.visibility = View.VISIBLE
        } else {
            holder.docUploadedText.visibility = View.GONE
        }
    }
} else {
    holder.docUploadedText.visibility = View.GONE
}

我已经为 SubmittedDocumentList 和 Solved 使用了循环
