我无法通过ViewPager将项目编号正确地传递给片段

public class MyPagerAdapter extends FragmentPagerAdapter {
    private int projectNumber;

    public MyPagerAdapter(FragmentManager fm, int projectNumber) {
        super(fm);
        this.projectNumber = projectNumber;
    }

    @Override
    public Fragment getItem(int position) {
        // 创建片段实例，并将项目编号传递给片段
        return MyFragment.newInstance(projectNumber);
    }

    @Override
    public int getCount() {
        // 返回片段的数量
        return 3;
    }
}

public class MyFragment extends Fragment {
    private int projectNumber;

    public static MyFragment newInstance(int projectNumber) {
        MyFragment fragment = new MyFragment();
        Bundle args = new Bundle();
        args.putInt("projectNumber", projectNumber);
        fragment.setArguments(args);
        return fragment;
    }

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        if (getArguments() != null) {
            projectNumber = getArguments().getInt("projectNumber");
        }
    }

    // 其他片段相关代码...
}
