java - 迁移到 Androidx 后无法解析方法 setAdapter

Question

我尝试过类似的问题，但没有一个能解决我的问题。在我迁移到 androidx 这一行之前

slideViewPager.setAdapter(pagerAdapter)

很好，现在它抛出一个错误

Cannot resolve method 'setAdapter(com.fundi.passenger.home.submenu.home.HomeFragment.MyPagerAdapter)'

和slideIndicator.setViewPager(slideViewPager)

setViewPager (androidx.viewpager.widget.ViewPager)in CircleIndicator cannot be applied to (cn.trinea.android.view.autoscrollviewpager.AutoScrollViewPager)

波纹管是我的代码的一部分

   import androidx.fragment.app.Fragment;
   import androidx.fragment.app.FragmentManager;
   import androidx.fragment.app.FragmentPagerAdapter;
   import cn.trinea.android.view.autoscrollviewpager.AutoScrollViewPager;
   public class HomeFragment extends Fragment {
    public ArrayList<Banner> banners = new ArrayList<>();
     AutoScrollViewPager slideViewPager;

           @Override
            public void onResponse(Call<GetBannerResponseJson> call, Response<GetBannerResponseJson> response) {
                if (response.isSuccessful()) {
                    banners = response.body().data;
                    Log.e("Image", response.body().data.get(0).foto);
                    MyPagerAdapter pagerAdapter = new MyPagerAdapter(getChildFragmentManager(), banners);
                    slideViewPager.setAdapter(pagerAdapter);
                    slideIndicator.setViewPager(slideViewPager);
                    slideViewPager.setInterval(6000);
                    slideViewPager.startAutoScroll(6000);
                }
            }

    public static class MyPagerAdapter extends FragmentPagerAdapter {
        private static int NUM_ITEMS = 5;
        public ArrayList<Banner> banners = new ArrayList<>();

        public MyPagerAdapter(FragmentManager fragmentManager, ArrayList<Banner> banners) {
            super(fragmentManager);
            this.banners = banners;
        }

        @Override
        public int getCount() {
            return banners.size();
        }

        @Override
        public Fragment getItem(int position) {
            return SlideFragment.newInstance(banners.get(position).id, banners.get(position).foto);
        }

        @Override
        public CharSequence getPageTitle(int position) {
            return "Page " + position;
        }


    }

}

我认为这是因为外部库与 AndroidX 不兼容。 (假设通过查看它的 GitHub 历史记录)

I found this library having AndroidX compatibility: https://github.com/siralam/LoopingViewPager

还有一种方法是使用 Android 的 native 库并导入 androidx.viewpager.widget.ViewPager

示例:

Adapter adapter = new Adapter(getSupportFragmentManager());
adapter.addFragment(first, "First");
adapter.addFragment(second, "Second");
adapter.addFragment(third, "Third");
myViewPager.setAdapter(adapter);

// Auto Scroll
Handler handler = new Handler();

Runnable update = new Runnable() {
    public void run() {
        if (currentPage == NUM_PAGES - 1) {
            currentPage = 0;
        }
        myViewPager.setCurrentItem(currentPage++, true);
    }
};


new Timer().schedule(new TimerTask() {

    @Override
    public void run() {
        handler.post(update);
    }
}, 100, 500);

您必须更新您的代码来实现它。
