¿Agregar pestaña dentro de Fragment en Android?

Estoy tratando de agregar un TabHost dentro de un Fragmento. El código se da a continuación. Aquí dentro del Fragmento. Estoy intentando agregar TabHost para mostrar dos tabs:

package com.nordicsoft.dilosysNewVersion; import android.app.Fragment; import android.content.Intent; import android.os.Bundle; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; import android.widget.TabHost; public class Fragment_Coupons extends Fragment { TabHost tabHost; TabHost.TabSpec spec; public Fragment_Coupons() { } @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View rootView = inflater.inflate(R.layout.fragment_coupon, container, false); tabHost = (TabHost) rootView.findViewById(android.R.id.tabhost); tabHost.setup(); //Add_Text_To_Tab("Android", "IOS"); Intent intentAndroid = new Intent().setClass(getActivity(), Aclass.class); spec = tabHost.newTabSpec("Android").setContent(intentAndroid) .setIndicator("Android"); tabHost.addTab(spec); Intent intentBus = new Intent().setClass(getActivity(), Bclass.class); spec = tabHost.newTabSpec("Welcome").setIndicator("Welcome") .setContent(intentBus).setIndicator("Welcome"); tabHost.addTab(spec); return rootView; } } 

El código XML:

        

Esto me está dando el error:

PID: 18103 SIG: 9 

Intenta hacer esto para manejar las tabs:

 public class MainFragment extends Fragment { private FragmentTabHost mTabHost; //Mandatory Constructor public MainFragment() { } public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); } public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View rootView = inflater.inflate(R.layout.fragment_tabs,container, false); mTabHost = (FragmentTabHost)rootView.findViewById(android.R.id.tabhost); mTabHost.setup(getActivity(), getChildFragmentManager(), R.id.realtabcontent); mTabHost.addTab(mTabHost.newTabSpec("fragmentb").setIndicator("Fragment B"), FragmentB.class, null); mTabHost.addTab(mTabHost.newTabSpec("fragmentc").setIndicator("Fragment C"), FragmentC.class, null); mTabHost.addTab(mTabHost.newTabSpec("fragmentd").setIndicator("Fragment D"), FragmentD.class, null); return rootView; } } 

Con el diseño:

      

The MotherActivity para alojar el MainFragment:

 public class MotherActivity extends FragmentActivity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); MainFragment fragmenttab = new MainFragment(); getSupportFragmentManager().beginTransaction() .add(R.id.item_detail_container, fragmenttab).commit(); } 

Y diseño de MotherActivity:

  

Después de esto simplemente crea el fragmento normal B y C, etc. Clase. El resultado será:

Fragmento de pestaña dentro del resultado del fragmento

Prueba agregar esta línea

 tabHost.setup(this.getActivity().getLocalActivityManager()); 

antes de la línea

 tabHost.addTab(spec); 

o intente agregar:

 LocalActivityManager mLocalActivityManager = new LocalActivityManager(this.getActivity(), false); mLocalActivityManager.dispatchCreate(savedInstanceState); host.setup(mLocalActivityManager);
