EditText text = (EditText) findViewById(R.id.text); возвращает null

Весь этот список инициализируется как null, а это проблема. Объясните почему так?

        EditText  passwordEt = (EditText) findViewById(R.id.passwordEdit);//=null
        EditText emailEt = (EditText) findViewById(R.id.emailEdit);//=null
        EditText questionEdit = (EditText) findViewById(R.id.questionEdit);//=null
        EditText answerEdit = (EditText) findViewById(R.id.answerEdit);//=null
        EditText  nicknameEt = (EditText) findViewById(R.id.nicknameEdit);//=null
