ViewPager2 迁移后出现无效 ID 0x00000001 错误

问题描述

我一直在使用 ViewPager 使用 Tab 布局，但它已被弃用。我按照官方文档迁移到ViewPager2，一切正常，但我在每个片段上收到以下错误：

无效 ID 0x00000001 无效 ID 0x00000001 无效 ID 0x00000001

每次我在片段之间滑动时，这些都会增加.. 没有崩溃，但每次我重新打开活动时，数字都会增加到无效 ID 0x00000002 等等。

我对消除此错误的解决方案感到迷茫，但该应用程序仍然适用于新的 ViewPager2。有什么想法可以解决错误的垃圾邮件吗？

活动代码：

//Responsible for adding the 4 tabs: NewLoot,ActiveLoot,SharedLoot,FinishedLoot
    private void setupViewPager(){
        SectionsPagerAdapter adapter = new SectionsPagerAdapter(getSupportFragmentManager(),getLifecycle());
        adapter.addFragment(new NewLootFragment());//index 0
        adapter.addFragment(new ActiveLootFragment());//index 1
        adapter.addFragment(new FinishedLootFragment());//index 2
        ViewPager2 viewPager = (ViewPager2) findViewById(R.id.container);
        viewPager.setAdapter(adapter);
        final TabLayout tabLayout = (TabLayout) findViewById(R.id.tab_layout);
        new TabLayoutMediator(tabLayout,viewPager,new TabLayoutMediator.TabConfigurationStrategy() {
                    @Override
                    public void onConfigureTab(@NonNull TabLayout.Tab tab,int position) {
                        //tab.setText("OBJECT " + (position + 1));
                    }
                }
        ).attach();
        tabLayout.getTabAt(0).setIcon(R.drawable.ic_search);
        tabLayout.getTabAt(1).setIcon(R.drawable.ic_arrow);
        tabLayout.getTabAt(2).setIcon(R.drawable.ic_action_name);

        tabLayout.getTabAt(0).getIcon().setColorFilter(getResources().getColor(R.color.red),PorterDuff.Mode.SRC_IN);
        tabLayout.getTabAt(1).getIcon().setColorFilter(getResources().getColor(android.R.color.black),PorterDuff.Mode.SRC_IN);
        tabLayout.getTabAt(2).getIcon().setColorFilter(getResources().getColor(android.R.color.black),PorterDuff.Mode.SRC_IN);

        tabLayout.addOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {
            @Override
            public void onTabSelected(TabLayout.Tab tab) {
                tab.view.getTab().getIcon().setColorFilter(getResources().getColor(R.color.red),PorterDuff.Mode.SRC_IN);
            }           @Override
            public void onTabUnselected(TabLayout.Tab tab) {
                tab.view.getTab().getIcon().setColorFilter(getResources().getColor(android.R.color.black),PorterDuff.Mode.SRC_IN);
            }           @Override
            public void onTabReselected(TabLayout.Tab tab) {
            }
        });

    }

SectionPagerAdapter 代码：

//Class that stores fragments for tabs
public class SectionsPagerAdapter extends FragmentStateAdapter {
    private static String TAG = "SectionsPagerAdapter";

    private final ArrayList<Fragment> mFragmentList = new ArrayList<>();

    public SectionsPagerAdapter(@NonNull FragmentManager fragmentManager,@NonNull Lifecycle lifecycle){
        super(fragmentManager,lifecycle);
    }

    //public ViewPagerFragmentAdapter(@NonNull FragmentManager fragmentManager,@NonNull Lifecycle lifecycle) {
    //    super(fragmentManager,lifecycle);
    //}

    public void addFragment(Fragment fragment){
        mFragmentList.add(fragment);
    }

    @NonNull
    @Override
    public Fragment createFragment(int position) {
        return mFragmentList.get(position);
    }

    @Override
    public int getItemCount() {
        return mFragmentList.size();
    }
}
