onActivityResult() never called

Question

I have a problem with onActivityResult() and setResult().

I started android development 1 week ago so sorry.

Could you help me?

here is a snippet of my code :

ListActivity function Click

    val myadapter = ItemAdapter();
    list_recycler_view.layoutManager = LinearLayoutManager(this)
    list_recycler_view.adapter = myadapter
    val me = this;
        myadapter.setOnItemClickListener(object : ItemAdapter.OnItemClickListener {
            override fun onItemClick(item: Item) {
                val intent = Intent(me, DetailActivity::class.java)
                intent.putExtra("item", item)
                startActivityForResult(intent, 2)
            }
        })

List activity function onActivityResult

    override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
        super.onActivityResult(requestCode, resultCode, data)
        Log.d("reponse","coucou5");
        Log.d("reponse",requestCode.toString());
        Log.d("reponse",resultCode.toString());
        if (requestCode == 2 && resultCode == RESULT_OK) {

            val item = data?.getParcelableExtra<Item>("item") as Item
            Log.d("reponse-update",item.toString());
            if (item == null) {
                Toast.makeText(this, "Could not update! Error!", Toast.LENGTH_SHORT).show()
            }

            //ItemListViewModel.update(item);

        } else {
            Toast.makeText(this, "Note not saved!", Toast.LENGTH_SHORT).show()
        }
    }

DetailActivity function on click

     btnSave.setOnClickListener{
            //other props
            item.gid = gid;
            item.distance = distance
            Log.d("reponse",item.toString());
            Log.d("reponse","coucou4");
            val returnIntent = intent
            returnIntent.putExtra("item", item)
            setResult(Activity.RESULT_OK, returnIntent)
            finish()
        }

it seems that the onActivityResult() is never called

Answer 1

it seems that i was declare 2 listener on the adapter so the startActivityForResult doesnt fire
