I have an `Activity`, which has a `RecyclerView` and save `Button`. Each item (football match) of the `RecyclerView` contains some text (name of teams) and `EditText`, where user enters data (actually bet the match). My goal is to save those scores to the list in the `Activity`, when user clicked on save `Button`.

I implemented this method in `Activity`, which actually get particular item from `LinearLayoutManager` and then get data from `EditText`, but the `findViewByPosition()` method (or getChildAt() there are different way to do this) sometimes returns null.

I saw another answers on similar question, but they didn't help me. Maybe my strategy is wrong, because I made whole my logic in Activity (better to do this in Adapter?) and I get though all of my items in `RecyclerView` even if only in one user entered the score.

```java
    private List<Bet> getUserBets() {
        View betView;
        Bet betItem;
        EditText userBet1;
        EditText userBet2;

        int numberOfMatches = rvBetsAdapter.getItemCount();
        List<Bet> bets = new ArrayList<>();

        for (int i = 0; i < numberOfMatches; i++)
        {
            betItem = rvBetsAdapter.getItem(i);
            betView = linearLayoutManager.findViewByPosition(i); 
            userScore1 = (EditText) betView.findViewById(R.id.result1); // <- NPE appears
            userScore2 = (EditText) betView.findViewById(R.id.result2);
            //here i checked whether the editText is empty and other stuff
            bets.add(betItem);
        }
        return bets;
    }

```

How do I fix it? I suppose I should do something in onBindViewHolder method in my adapter, but what exactly? 
I would really appreciate any help.
