Android 如何获取用另一个类扩展的片段视图？

标题有点混乱，但我不知道该写什么

我正在使用库为我的应用程序（）的开始公开一个滑动教程。问题是我需要在带有findViewById的片段中找到一个视图，但是我需要从片段的视图派生这个调用。我应该使用onCreateView方法，但正如我在标题中所说的，我的片段需要从TutorialSupportFragment扩展（尽管有片段），因此如果我重写onCreateView方法，库中的一些组件将无法加载

有没有一种方法可以在不破坏扩展方法的情况下使用此onCreateView

public class CustomTutorialFragment extends TutorialSupportFragment implements OnTutorialPageChangeListener, CustomTutorialMvpView {

...

我需要运行以下程序：

@Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container,
                             @Nullable Bundle savedInstanceState) {
        View view = inflater.inflate(getLayoutResId(), container, false);

        btNext = (Button) view.findViewById(R.id.btNext);
        btSkip = (Button) view.findViewById(R.id.btSkip);

        btNext.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                nextPage();
            }
        });

        btSkip.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                skipTutorial();
            }
        });

        return view;
    }

这就是错误，我认为问题在于我可以重写该方法，而不破坏库创建的前一个方法

你有两个选择

第一个是调用

super.onCreateView（）

，并使用返回的

视图执行操作：

@Nullable
@Override
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
    View view = super.onCreateView(inflater, container, savedInstanceState);
    // Perform necessary actions
    Button button = view.findViewById(R.id.button);
    return view;
}

第二个选项是覆盖
onViewCreated（）

你能显示代码吗？没有它很难理解。抱歉，发布了。看一看。你能显示代码吗？因为没有它很难理解。发布了，对不起。看一看。
