我需要在应用程序中具有拍照功能，然后将其存储在 recyclerView 中

  • 问题是我的 AlertDialog 中没有显示带有拍摄图像的回收站视图。
  • 我怀疑两种可能的结果是我是否在我的活动中错误地设置了回收站视图，或者我的适配器中没有正确提供图像。

如下提供：

负责显示对话框的函数

private fun showRequestAcceptDialog() {

    var listOfPhotoFileNames: MutableList<File?> = arrayListOf()
    var listOfPhotoFileURIs: MutableList<Uri> = arrayListOf()



    val dialogBuilder = AlertDialog.Builder(this)
    dialogBuilder.setMessage("Принятие ЧО")

    val dialogView = layoutInflater.inflate(R.layout.dialog_accept_draft, null)

    val btnMakePhoto = dialogView.findViewById<Button>(R.id.btnMakePhoto)

    val etComment = dialogView.findViewById<EditText>(R.id.etDialogAcceptDraft)

    val recyclerView = dialogView.findViewById<RecyclerView>(R.id.rvAcceptPhotos)

    ivDialogAcceptPhoto = dialogView.findViewById<ImageView>(R.id.ivDialogAcceptDraft)
    ivDialogAcceptPhoto_1 = dialogView.findViewById<ImageView>(R.id.ivDialogAcceptDraft_1)
    etComment.hint = "Комментарий"

    dialogBuilder.setCancelable(false)
    dialogBuilder.setView(dialogView)


    adapter_dialog = RequestCheckStatusListDialogAdapter()
    recyclerView.adapter = adapter_dialog
    val layoutManager = LinearLayoutManager(this@RequestCheckStatusListActivity)
    recyclerView.layoutManager = layoutManager



    btnMakePhoto?.setOnClickListener {
        Intent(MediaStore.ACTION_IMAGE_CAPTURE).also { takePictureIntent ->
            // Ensure that there's a camera activity to handle the intent
            takePictureIntent.resolveActivity(packageManager)?.also {
                // Create the File where the photo should go
                val photoFile: File? = try {
                    createImageFile()
                } catch (ex: IOException) {
                    ex.printStackTrace()
                    null
                }
                listOfPhotoFileNames.add(photoFile)
                listOfPhotoPaths.add(currentPhotoPath)
                // Continue only if the File was successfully created
                photoFile?.also {
                    val photoURI: Uri = FileProvider.getUriForFile(
                            this,
                            applicationContext.packageName + ".fileprovider",
                            it
                    )
                    listOfPhotoFileURIs.add(photoURI)
                    takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, photoURI)
                    startActivityForResult(takePictureIntent, REQUEST_IMAGE_CAPTURE)
                }

            }
        }
    }
    

    dialogBuilder.setPositiveButton("Подтвердить", null)
    dialogBuilder.setNegativeButton("Отмена", null)

    acceptRequestDialog = dialogBuilder.show()

    acceptRequestDialog!!.getButton(android.app.AlertDialog.BUTTON_POSITIVE)
        .setOnClickListener {
            if (currentPhotoPath != null) {
                presenter.acceptRequest(etComment.text.toString(), currentPhotoPath)
                showToast("$listOfPhotoPaths")
            }
            else
            {
                showToast("Прикрепите договор")
            }
        }

    acceptRequestDialog!!.getButton(android.app.AlertDialog.BUTTON_NEGATIVE)
        .setOnClickListener {
            closeAccpeptDialog()
        }
}
