Answer 1

you can do like this.

You should use TabLayout instead of TabHost.

Make Xml for main fragment which content Tabs.

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical">

<android.support.design.widget.TabLayout
    android:id="@+id/tabs"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    app:tabGravity="fill"
    app:tabMode="fixed" />

<android.support.v4.view.ViewPager
    android:id="@+id/viewpager"
    android:layout_width="match_parent"
    android:layout_height="0dp"
    android:layout_weight="1" />

</LinearLayout>

Then Make Code like below:

public class TabsFragment extends Fragment {

View view;
PagerAdapter adapter;

private void setupViewPager(ViewPager viewPager) {

///Here we have to pass ChildFragmentManager instead of FragmentManager.
      adapter = new PagerAdapter(getChildFragmentManager());
        adapter.addFragment(new Fragment1(), "Fragment1");
        adapter.addFragment(new Fragment2(), "Fragment2");
        viewPager.setAdapter(adapter);
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        view = inflater.inflate(R.layout.f_tabslayout, container, false);
        super.onCreate(savedInstanceState);

        final ViewPager viewPager = (ViewPager)view.findViewById(R.id.viewpager);
        setupViewPager(viewPager);
        TabLayout tabLayout = (TabLayout)view.findViewById(R.id.tabs);
        tabLayout.setupWithViewPager(viewPager);
        return view;
    }

    @Override
    public void onDestroyView() {
        super.onDestroyView();

    }

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

        public Adapter(android.support.v4.app.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);
        }
    }
}

Answer 2

I am assuming that you have implemented Navigation Drawer, and having trouble in calling tabhost in fragment.

Try the following steps.

1. Create a parent fragment to hold the tab, in this fragment add as many tabs as you want to add. (In this example I am showing two tabs).
2. Create the fragments that you have added in the tabs. (Fragment1, Fragment2)

ParentFragment.java

public class ParentView extends Fragment {
    private FragmentTabHost mTabHost;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        mTabHost = new FragmentTabHost(getActivity());
        mTabHost.setup(getActivity(), getChildFragmentManager(), R.layout.fragment_parent_view);
        mTabHost.getTabWidget().setBackgroundColor(getResources().getColor(R.color.color_primary_dark));  // if you want to set color of tab

        Bundle arg1 = new Bundle();
        arg1.putString("aim", "passingvalues1");

        mTabHost.addTab(mTabHost.newTabSpec("Tab1").setIndicator("NAME1"),
                Fragment1.class, arg1);

        Bundle arg2 = new Bundle();
        arg2.putString("aim", "passingvalues2");
        mTabHost.addTab(mTabHost.newTabSpec("Tab2").setIndicator("Name2"),
                Fragment2.class, arg2);

         return mTabHost;
    }

    @Override
    public void onDestroyView() {
        super.onDestroyView();
        mTabHost = null;
    }


}

fragment_parent_view.xml

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="com.xx.xx.xx.ParentFragment">


</FrameLayout>

Fragment1.java

    public class Fragment1 extends Fragment 
    {
        private LinearLayout llLayout;
        @Override
        public View onCreateView(LayoutInflater inflater, ViewGroup container,
                                 Bundle savedInstanceState) 
        {
            llLayout    = (LinearLayout)inflater.inflate(R.layout.fragment1, container, false);
            return llLayout;
        }
    }

Fragment2.java

    public class Fragment2 extends Fragment 
    {
        private LinearLayout llLayout;
        @Override
        public View onCreateView(LayoutInflater inflater, ViewGroup container,
                                 Bundle savedInstanceState) 
        {
            llLayout    = (LinearLayout)inflater.inflate(R.layout.fragment2, container, false);
            return llLayout;
        }
    }
