Question

我通过替换帧布局来调用视图寻呼机片段，但是当我再次调用它时，视图寻呼机的最后加载片段显示为空白。

//这里我将替换主要活动中的视图寻呼机片段

All_Women_Categories fragment = new All_Women_Categories();

            fragmentManager = getSupportFragmentManager();
            fragmentManager.beginTransaction()
                    .replace(R.id.frame_container, fragment).commit();

//这是我所谓的查看分页器片段

public class All_Ethnic_Fragment extends Fragment {
    private static SectionsPagerAdapter mSectionsPagerAdapter;
    private static ViewPager mViewPager;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        View rootView = inflater.inflate(R.layout.all_women_ethnic_view_pager,
                container, false);
        mViewPager = (ViewPager) rootView.findViewById(R.id.women_ethnic_pager);



            mSectionsPagerAdapter = new SectionsPagerAdapter(getActivity()
                    .getSupportFragmentManager());
            mViewPager.setAdapter(mSectionsPagerAdapter);


        return rootView;
    }

    public class SectionsPagerAdapter extends FragmentPagerAdapter {

        public SectionsPagerAdapter(FragmentManager fm) {
            super(fm);
        }

        @Override
        public Fragment getItem(int position) {

            switch (position) {
            case 0:
                return Sarees.newInstance("Hello");
            case 1:
                return Lehengas.newInstance("Hello");
            case 2:
                return Salwars_n_Churidars.newInstance("Hello");
            case 3:
                return Kurtis.newInstance("Hello");
            case 4:
                return Dress_Materials.newInstance("Hello");
            case 5:
                return Stitched_Suits.newInstance("Hello");

            }
            return null;
        }

        @Override
        public int getCount() {
            // Show 3 total pages.
            return 6;
        }

        @Override
        public CharSequence getPageTitle(int position) {

            switch (position) {
            case 0:
                return getString(R.string.sarees).toUpperCase();
            case 1:
                return getString(R.string.lehngas).toUpperCase();
            case 2:
                return getString(R.string.salwars).toUpperCase();
            case 3:
                return getString(R.string.kurti).toUpperCase();
            case 4:
                return getString(R.string.dress_material).toUpperCase();
            case 5:
                return getString(R.string.stiched).toUpperCase();
            }
            return null;
        }
    }
}

如果有人得到了什么，那么请告诉我.. 谢谢..

我不确定我是否收到了您的问题，但我认为您应该堆叠片段而不是替换它们。而不是

                .replace(R.id.frame_container, fragment).commit();

您应该尝试使用add(Fragment fragment)，remove()和/或show(Fragment fragment)。这样，您可以先添加所有片段，然后根据需要决定显示/隐藏它们。
