onActivityResult() never called

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

I think it is because you are not creating another intent to send the info back, please do this and check if that works for you.

Do this in your detail activity instead of your code just paste this.

btnSave.setOnClickListener{
        //other props
        item.gid = gid;
        item.distance = distance
        Log.d("reponse",item.toString());
        Log.d("reponse","coucou4");
        Intent returnIntent = Intent();
        returnIntent.putExtra("item", item)
        setResult(2, returnIntent)
        finish()
    }

you are passing RESULT_OK which isn't required and it's processed by the Android framework itself.

Replace 

val returnIntent = intent

For 

val returnIntent = new Intent()
