如何在向EditText中添加行时动态更改我的ScrollView？

public class MainActivity extends AppCompatActivity {
    private LinearLayout layout;
    private ScrollView scrollView;
    private List<EditText> editTextList;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        layout = findViewById(R.id.layout);
        scrollView = findViewById(R.id.scrollView);
        editTextList = new ArrayList<>();

        EditText editText = findViewById(R.id.editText);
        editText.addTextChangedListener(new TextWatcher() {
            @Override
            public void beforeTextChanged(CharSequence s, int start, int count, int after) {
            }

            @Override
            public void onTextChanged(CharSequence s, int start, int before, int count) {
            }

            @Override
            public void afterTextChanged(Editable s) {
                String text = s.toString();
                if (text.endsWith("\n")) {
                    addNewLine();
                }
            }
        });
    }

    private void addNewLine() {
        EditText newEditText = new EditText(this);
        newEditText.setLayoutParams(new LinearLayout.LayoutParams(
                LinearLayout.LayoutParams.MATCH_PARENT,
                LinearLayout.LayoutParams.WRAP_CONTENT));
        layout.addView(newEditText);
        editTextList.add(newEditText);

        scrollView.post(new Runnable() {
            @Override
            public void run() {
                scrollView.scrollTo(0, newEditText.getBottom());
            }
        });
    }
}
