如何从onCreateView中的另一个函数获取数据？

public class MyFragment extends Fragment {
    private OnDataReceivedListener mListener;

    public interface OnDataReceivedListener {
        void onDataReceived(String data);
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        // ...
        getData();
        // ...
    }

    private void getData() {
        // 获取数据的逻辑
        String data = "这是要获取的数据";
        if (mListener != null) {
            mListener.onDataReceived(data);
        }
    }

    public void setOnDataReceivedListener(OnDataReceivedListener listener) {
        mListener = listener;
    }
}

MyFragment fragment = new MyFragment();
fragment.setOnDataReceivedListener(new MyFragment.OnDataReceivedListener() {
    @Override
    public void onDataReceived(String data) {
        // 在这里获取到数据
        Log.d("TAG", "Received data: " + data);
    }
});

public class MyFragment extends Fragment implements DataProvider {
    private TextView mTextView;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        // ...
        mTextView = rootView.findViewById(R.id.text_view);
        getData();
        // ...
    }

    private void getData() {
        // 获取数据的逻辑
        String data = "这是要获取的数据";
        onDataReceived(data);
    }

    @Override
    public void onDataReceived(String data) {
        // 在这里获取到数据
        mTextView.setText(data);
    }
}

public interface DataProvider {
    void onDataReceived(String data);
}

MyFragment fragment = new MyFragment();
// ...

public class MyFragment extends Fragment {
    private String mData;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        // ...
        getData();
        // ...
    }

    private void getData() {
        // 获取数据的逻辑
        mData = "这是要获取的数据";
    }

    private void anotherFunction() {
        // 在这里获取到数据
        Log.d("TAG", "Data: " + mData);
    }
}
