对于新的View.OnClickListener（）{}类型，未定义方法userAccounts（）

Question

I've got a userAccounts class that declares all the variables for my user accounts. But when trying to increase the size of an arrayList of type userAccounts on a button press i get the error.

The method userAccounts() is undefined for the type new View.OnClickListener(){}

The code is:

public class CreateAccount extends Activity {
ArrayList<userAccounts> accountArray = new ArrayList<userAccounts>();
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_create_account);



    final Button buttonCreate = (Button) findViewById(R.id.btnCreate);
    buttonCreate.setOnClickListener(new View.OnClickListener() {
        public void onClick(View v) {

            accountArray.add(userAccounts());

Answer 1

Probably, if you want to add new item to your list, you should change accountArray.add(userAccounts()) to accountArray.add(new userAccounts()) . Your variant supposes that you call some method userAccounts() dedicated to the listener class.
