当我在viewpager中滑动到或从相邻片段（0，2）中选择fragment1（片段编号为0-3）时，它的oncreateview或oncreate函数没有被调用。
但是当我从fragment3滑回或在fragment3激活时选择fragment1时，这两个函数都被调用。我不明白为什么不能从相邻的片段中调用它。
这是未正确调用oncreateview的片段的代码
`公共类fragment1扩展了fragment{

ShimmerFrameLayout shimmerFrameLayout ;
ConstraintLayout contentLayout;

@Override
public void onCreate(@Nullable Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    Toast.makeText(getActivity(), "US News", Toast.LENGTH_SHORT).show();
    Log.d("Called", "onCreate: ");
}

@Nullable
@Override
public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {

    View view = inflater.inflate(R.layout.us_news_fragment_layout , container , false);
    shimmerFrameLayout = view.findViewById(R.id.usNewsShimmerLayoutId);
    contentLayout = view.findViewById(R.id.usNewsLayoutId);

    shimmerFrameLayout.startShimmerAnimation();

    new Handler().postDelayed(new Runnable() {
        @Override
        public void run() {
           shimmerFrameLayout.stopShimmerAnimation();
           shimmerFrameLayout.setVisibility(View.GONE);
           contentLayout.setVisibility(View.VISIBLE);
        }
    },3000);
    return view;
}

@Override
public void onViewCreated(@NonNull View view, @Nullable Bundle savedInstanceState) {
    super.onViewCreated(view, savedInstanceState);
    Log.d("USNews", "onCreateView: ");
}

}`
这是主活动中用于处理与viewpager相关的事件的代码

viewPager = findViewById(R.id.homeViewPagerId);
    tabLayout.setupWithViewPager(viewPager);
    tabLayout.addTab(tabLayout.newTab().setText("Home"));
    tabLayout.addTab(tabLayout.newTab().setText("US News"));
    tabLayout.addTab(tabLayout.newTab().setText("Politics"));
    tabLayout.addTab(tabLayout.newTab().setText("Live"));
    tabLayout.setTabGravity(TabLayout.GRAVITY_FILL);
    tabLayout.addOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {
        @Override
        public void onTabSelected(TabLayout.Tab tab) {
            int position = tab.getPosition();
            viewPager.setCurrentItem(position);
        }

        @Override
        public void onTabUnselected(TabLayout.Tab tab) {

        }

        @Override
        public void onTabReselected(TabLayout.Tab tab) {

        }
    });

    homePagerAdapter = new HomePagerAdapter(getSupportFragmentManager() , tabLayout.getTabCount());
    viewPager.setAdapter(homePagerAdapter);
    viewPager.addOnPageChangeListener(new ViewPager.OnPageChangeListener() {

        @Override
        public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {

//toast.maketext（mainactivity.this，string.valueof（tablayout.gettabat（position.gettext（））+“现在处于活动状态”，toast.length\u short.show（）；homepageradapter.getitem（位置）；}

@Override
        public void onPageSelected(int position) {
            homePagerAdapter.getItem(position);
        }

        @Override
        public void onPageScrollStateChanged(int state) {

        }
    });

    homePagerAdapter.notifyDataSetChanged();

这是我正在使用的viewpager的适配器

public class HomePagerAdapter extends FragmentStatePagerAdapter {
int NUM_OF_TABS;
private String[] tabTitles = new String[]{"Home", "US News", "Politics" , "Live"};
public HomePagerAdapter(@NonNull FragmentManager fm , int numberOfTabs) {
    super(fm);
    this.NUM_OF_TABS = numberOfTabs;
}

@Nullable
@Override
public CharSequence getPageTitle(int position) {
    return tabTitles[position];
}

@NonNull
@Override
public Fragment getItem(int position) {
    switch (position){
        case 0:
            Fragment0 homeFragment = new Fragment0 ();
            return  homeFragment;
        case 1:
            Fragment1 usNewsFragment = new Fragment1 ();
            return usNewsFragment;
        case 2:
            Fragment2 politicsFragment = new Fragment2 ();
            return politicsFragment;
        case 3:
            Fragment3 liveFragment = new Fragment3 ();
            return  liveFragment;
        default:
            return null;
    }
}

@Override
public int getCount() {
    return NUM_OF_TABS;
}

}
请帮我处理这件事。我会非常感谢你的。
提前谢谢
