ViewPager with TabPayout Fragment içinde çalışmıyor Android

Question

Merhaba Bir parçanın içinde bir TabLayout ve ViewPager var. Ancak, çocuk parçasına gelmek için sekme arasında kayarım yapamıyorum (Normalde Etkinlikte çalışırken ancak parçalı olarak çalışmıyorsa). ,

viewPager.setAdapter(new CustomAdapter(getFragmentManager(), getContext())); 

Anyhelp kadar takdir edilir bir yapmış teşekkür

: Ben bu hat ile sorun var şüphe

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

     View inflateView = inflater.inflate(R.layout.fragment_assign_beacon_to_event, container, false); 

     //Viewpager and TabLayout 
     viewPager = (ViewPager)inflateView.findViewById(R.id.viewPager); 
     viewPager.setAdapter(new CustomAdapter(getFragmentManager(), getContext())); 

     tabLayout = (TabLayout)inflateView.findViewById(R.id.tabLayout); 


     // Inflate the layout for this fragment 
     return inflateView; 
    } 

@Override 
    public void onActivityCreated(Bundle savedInstanceState) { 
     super.onActivityCreated(savedInstanceState); 

    tabLayout.post(new Runnable() { 
       @Override 
       public void run() { 
        tabLayout.setupWithViewPager(viewPager); 

      } 
     }); 

     tabLayout.setOnTabSelectedListener(new TabLayout.OnTabSelectedListener() { 
      @Override 
      public void onTabSelected(TabLayout.Tab tab) { 
       viewPager.setCurrentItem(tab.getPosition()); 
      } 

      @Override 
      public void onTabUnselected(TabLayout.Tab tab) { 
       viewPager.setCurrentItem(tab.getPosition()); 
      } 

      @Override 
      public void onTabReselected(TabLayout.Tab tab) { 
       viewPager.setCurrentItem(tab.getPosition()); 
      } 
     }); 

Any here is my Custom Adapter class 

private class CustomAdapter extends FragmentPagerAdapter { 

     private String fragments[] = {"Assign Event", "Manage Event"}; 

     public CustomAdapter(FragmentManager supportFragmentManager, Context applicationContext) { 
      super(supportFragmentManager); 
     } 

     @Override 
     public Fragment getItem(int position) { 
      switch (position) { 
       case 0: 
//     return new AssignEventToBeacon(); 
        return new Test1(); 
       case 1: 
        return new ManageEventAssigned(); 
       default: 
        return null; 
      } 
     } 

     @Override 
     public int getCount() { 
      return fragments.length; 
     } 

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

    }

fragmanı içindeki Tablayout benim kodudur Benzer proje ve iş parçacığı için kodum:

@Override 
    public View onCreateView(LayoutInflater inflater, ViewGroup container, 
          Bundle savedInstanceState) { 
     // Inflate the layout for this fragment 
     View view = inflater.inflate(R.layout.outer_fragment, container, false); 
     setHasOptionsMenu(true); 

     ViewPager viewPager = (ViewPager) view.findViewById(R.id.viewpager); 
     if (viewPager != null) { 
      setupViewPager(viewPager); 
     } 

     Log.v("Layout","Tabs"); 
     TabLayout tabLayout = (TabLayout) view.findViewById(R.id.tabs); 
     tabLayout.setSelectedTabIndicatorColor(Color.parseColor("#FFFFFF")); 
     tabLayout.setTabTextColors(Color.parseColor("#707070"), Color.parseColor("#FFFFFF")); 
     assert viewPager != null; 
     tabLayout.setupWithViewPager(viewPager); 

     return view; 
    } 

private void setupViewPager(ViewPager viewPager) { 
     Adapter adapter = new Adapter(getChildFragmentManager()); 
     adapter.addFragment(new Tab1Fragment(), "PHOTOS"); 
     adapter.addFragment(new Tab2Fragment(), "HI-FIVES"); 
     viewPager.setAdapter(adapter); 
    } 


static class Adapter extends FragmentPagerAdapter { 
     private final List<Fragment> mFragments = new ArrayList<>(); 
     private final List<String> mFragmentTitles = new ArrayList<>(); 

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

     public void addFragment(Fragment fragment, String title) { 
      mFragments.add(fragment); 
      mFragmentTitles.add(title); 
     } 

     @Override 
     public Fragment getItem(int position) { 
      return mFragments.get(position); 
     } 

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

     @Override 
     public CharSequence getPageTitle(int position) { 
      return mFragmentTitles.get(position); 
     } 
    }
