When I delete an item in recyclerview and then I add a new item, the items I deleted appear again on my Android app. I used the init in my Adapter to call the setonClickLister. I think that I need to call this code in my Activity but how will ı do ? I use the kotlin and how can ı fix it ? I shared my adapter code below to see clearly, thanx
class NoteAdapter(private var titleText: ArrayList<String>, private var imageButton: ArrayList<String>, private var noteText: ArrayList<String>) : RecyclerView.Adapter<NoteAdapter.ViewHolder>() {
inner class ViewHolder(itemView: View) : RecyclerView.ViewHolder(itemView) {
val itemTitle : TextView = itemView.findViewById(R.id.recyclerTitleText)
val itemImage : ImageView = itemView.findViewById(R.id.recyclerImage)
val itemDelete : ImageView = itemView.findViewById(R.id.delete)
init {
itemView.setOnClickListener { v: View ->
// Toast.makeText(itemView.context,"You clicked on item # ${position + 1}", Toast.LENGTH_SHORT).show()
val intent = Intent(itemView.context, PastNotesActivity::class.java)
intent.putExtra("oldTitle", titleText[position])
intent.putExtra("oldNote", noteText[position])
intent.putExtra("oldImage", imageButton[position])
itemView.context.startActivity(intent)
}
itemDelete.setOnClickListener { v: View ->
titleText.removeAt(position)
imageButton.removeAt(position)
notifyItemRemoved(position)
}
}
}
override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): ViewHolder {
val v = LayoutInflater.from(parent.context).inflate(R.layout.recycler_row, parent, false)
return ViewHolder(v)
}
override fun onBindViewHolder(holder: ViewHolder, position: Int) {
holder.itemTitle.text = titleText[position]
Picasso.get().load(imageButton[position]).resize(150,150).into(holder.itemImage)
}
override fun getItemCount(): Int {
return titleText.size
}
}
by the way, ı tried this code, but it does not work
notifyItemRemoved(position)
notifyItemRangeChanged(position, titletext.size)
