You can use Bundle to send arguments to the activity and back. For example, When the user clicks on an add button in the item in the RecyclerView. your adapter knows the position. As a matter of fact, your onClick must be implemented in your adapter. Send that position to the activity as putExtra before you startActvity. And then before finish you can again do putExtra.

//Your onClick handler in the Adapter class
Intent intent = new Intent(this, Activity.class);
intent.putExtra("position", position); //position in adapter
startActivityForResult(intent, REQ_CODE);



//in the next activity before finish()
Intent intent = getIntent();
itnent.putExtra("position", position);
finish();

//in your previous activity 
@Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {

    String pos = data.getStringExtra("position");
    adapter.getItem(Integer.parseInt(pos));
}
