How to set some action in generated buttons inside custom Adapter

Question

I got the following composition:

This layout is an Item of my RecyclerView.Adapter. The X button (holder.delete_button), when clicked, deletes himself and the EditText; basically it removes the row.

The ADD FIELD button add new rows (by inflater):

Here's the code to add new line:

  holder.add_field_button.setOnClickListener {
      holder.parent_layout.apply {
          val inflater = LayoutInflater.from(context)
          val rowView = inflater.inflate(R.layout.generated_layout, this, false)
          holder.parent_layout.addView(rowView, holder.parent_layout.childCount!! - 0)
      }
  }

My problem here is that I just can delete the first row, because is the only button I can initialize in the ViewHolder by the id of delete_button. But for the next X buttons, I can't do no action, because the button it's in an external layout inflated, called generated_layout! I've tried to generate ids but then I don't know how to put them into an array. Here's the code to delete a row:

holder.delete_button.setOnClickListener{
    holder.parent_layout.removeView(holder.delete_button.parent as View)
}

Here's the code of generated_layout, as well:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
              android:layout_width="match_parent"
              android:layout_height="50dp"
              android:orientation="horizontal" >
    <EditText
            android:layout_width="0dp"
            android:layout_height="match_parent"
            android:layout_weight="5"
            android:inputType="phone"/>
    <Button
            android:layout_width="40dp"
            android:layout_height="40dp"
            android:layout_weight="0"
            android:background="@android:drawable/ic_delete"/>
</LinearLayout>

Answer 1

Set the onClick listener like this

holder.add_field_button.setOnClickListener {
      holder.parent_layout.apply {
          val inflater = LayoutInflater.from(context)
          val rowView = inflater.inflate(R.layout.generated_layout, this, false)
          val rowViewDeleteButton=rowView.findViewById(R.id.deletebutton)
          rowViewDeleteButton.setOnClickListener{
            holder.parent_layout.removeView(it.parent as View)
          }

          holder.parent_layout.addView(rowView, holder.parent_layout.childCount!! - 0)
      }
  }

And give id to your delete button :

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
              android:layout_width="match_parent"
              android:layout_height="50dp"
              android:orientation="horizontal" >
    <EditText
            android:id="@+id/text"
            android:layout_width="0dp"
            android:layout_height="match_parent"
            android:layout_weight="5"
            android:inputType="phone"/>
    <Button
            android:id="@+id/deletebutton"
            android:layout_width="40dp"
            android:layout_height="40dp"
            android:layout_weight="0"
            android:background="@android:drawable/ic_delete"/>
</LinearLayout>
