Выдает ошибку textView

public class SecondActivity extends AppCompatActivity {

    private TextView text_content;
    private ImageView iContent;

    private int position = 0;
    private int category= 0;
    private int [] array_test = {R.string.out1, R.string.out2, R.string.out3, R.string.out4, R.string.out5};

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.secondactivity);
        text_content = findViewById(R.id.textView);

@layout/secondactivity does not contain a declaration with id textView - ошибка, как это исправить? сам id в разметке есть
