Как показать фрагмент диалога в button.setOnClickListener из класса адаптера в Kotlin-MVP?

Question

Я разрабатываю одно приложение для Android, используя эту структуру Kotlin-MVP . У меня есть одно действие, и оно содержит TabLayout из 4 фрагментов. Весь фрагмент имеет одну кнопку в RecyclerView. Мне нужно показать одно «Fragment Dialog» на слушателе щелчка этой кнопки. Подскажите, пожалуйста, как я могу показать диалог фрагмента при прослушивании нажатия кнопки из класса адаптера? Пожалуйста, просмотрите скриншот.

Я получаю доступ к кнопке на событии прослушивателя щелчков из класса Adapter, который находится ниже itemView.btn_accept.setOnClickListener:

class InApprovalAdapter(private val jobListItems: MutableList<JobItem>) : RecyclerView.Adapter<InApprovalAdapter.JobViewHolder>() {

private var _ProfileId: Long? = null;

fun getProfileId(): Long? {
    return _ProfileId
}

fun setProfileId(s: Long) {
    _ProfileId = s
}

private var _UserToken : String? = null;

fun getUserToken(): String? {
    return _UserToken
}

fun setUserToken(s: String) {
    _UserToken = s
}

private var _UserTypeId : Long? = null;
fun getUserTypeId(): Long? {
    return _UserTypeId
}

fun setUserTypeId(s: Long) {
    _UserTypeId = s
}


override fun getItemCount() = this.jobListItems.size

override fun onBindViewHolder(holder: JobViewHolder, position: Int) = holder.let {
    it.clear()
    it.onBind(position)
}

override fun onCreateViewHolder(parent: ViewGroup?, viewType: Int) = JobViewHolder(LayoutInflater.from(parent?.context)
        .inflate(R.layout.item_inapproval_list, parent, false))

internal fun addJobsToList(jobs: List<JobItem>, profileId: Long?, userToken: String?, userTypeId: Long?) {
    this.jobListItems.addAll(jobs)
    setProfileId(profileId!!.toLong())
    setUserToken(userToken!!)
    setUserTypeId(userTypeId!!)
    notifyDataSetChanged()
}

inner class JobViewHolder(view: View) : RecyclerView.ViewHolder(view) {

    fun clear() {
        itemView.tv_job_id.text = "";
        itemView.tv_job_title.text= "";
        //itemView.tv_job_description.text ="";
        itemView.tv_job_category.text ="";
        itemView.tv_date_created.text ="";
    }

    fun onBind(position: Int) {

Если у вас возникли проблемы с доступом к FragmentManager, вы можете просто передать лямбду своему адаптеру в качестве OnClickListener кнопки подтверждения:

class InApprovalAdapter(
    private val jobListItems: MutableList<JobItem>
    // If you have data to pass to the handler(like a jobId for example) 
    // modify the lambda like (Int) -> Unit
    private val acceptHandler: () -> Unit
    ) : RecyclerView.Adapter<InApprovalAdapter.JobViewHolder>() {

Тогда вы можете использовать эту лямбду:

itemView.btn_accept.setOnClickListener {
     acceptHandler()
}

Затем создайте адаптер:

val adapter = InApprovalAdapter(theListOfItems, val clickListener: (Item) -> Unit) {
    // I'm assuming you're creating this adapter inside the Fragment class
    // so at this point you can access getFragmentManager()
    // ideally you'll let the presenter know that something happened in the view: presenter.userAcceptedJob()
    // and the presenter will call back a method on the view to actually show the DialogFragment.
}
