You should use a DialogFragment, TabLayout and ViewPager. For instance, your dialog fragment's view may look like this:

Build your adapter and make sure you override the getPageTitleMethod, e.g:

public class CustomAdapter extends FragmentPagerAdapter {  
   List mFragmentCollection = new ArrayList<>();  
   List mTitleCollection = new ArrayList<>();  
   public CustomAdapter(FragmentManager fm) {  
     super(fm);  
   }  
   public void addFragment(String title, Fragment fragment)  
   {  
     mTitleCollection.add(title);  
     mFragmentCollection.add(fragment);  
   }  
   //Needed for  
   @Override  
   public CharSequence getPageTitle(int position) {  
     return mTitleCollection.get(position);  
   }  
   @Override  
   public Fragment getItem(int position) {  
     return mFragmentCollection.get(position);  
   }  
   @Override  
   public int getCount() {  
     return mFragmentCollection.size();  
   }  
 }

In the OnCreateView of your dialog, you should setup your viewpager with the tabLayout:

 public View onCreateView(LayoutInflater inflater,  ViewGroup container,  Bundle savedInstanceState) {  
     View rootview = inflater.inflate(R.layout.dialog_sample,container,false);  
     tabLayout = (TabLayout) rootview.findViewById(R.id.tabLayout);  
     viewPager = (ViewPager) rootview.findViewById(R.id.masterViewPager);  
     CustomAdapter adapter = new CustomAdapter(getChildFragmentManager());  
     adapter.addFragment("Boy",CustomFragment.createInstance("John"));  
     adapter.addFragment("Girl",CustomFragment.createInstance("Stacy"));  
     adapter.addFragment("Robot",CustomFragment.createInstance("Aeon"));  
     viewPager.setAdapter(adapter);  
     tabLayout.setupWithViewPager(viewPager);  
     return rootview;  
   } 

I have a blog post written on it here: here.
