Tabhost Android dans Tabhost ne fonctionne pas (problème XML je pense)

Question

Je l'ai fait avant, mais pour la vie de moi, je ne me souviens pas. Je veux un onglet avec dans un onglet. Ceci est mon MainActivity

protected void onCreate(Bundle savedInstanceState) 
    { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 


     TabHost tabHost = getTabHost(); 

     TabHost.TabSpec Login = tabHost.newTabSpec("Login"); 
     // setting Title and Icon for the Tab 
     Login.setIndicator("", getApplicationContext().getResources().getDrawable(R.drawable.tab1)); 
     Intent LoginIntent = new Intent(this, Tab1Activity.class); 
     LoginIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); 
     Login.setContent(LoginIntent); 


     // Tab for jobs 
     TabHost.TabSpec Jobs = tabHost.newTabSpec("Jobs"); 
     Jobs.setIndicator("", getApplicationContext().getResources().getDrawable(R.drawable.tab2)); 
     Intent JobsIntent = new Intent(this, Tab2Activity.class); 
     JobsIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); 
     Jobs.setContent(JobsIntent); 


     TabHost.TabSpec Jobs3 = tabHost.newTabSpec("Jobs3"); 
     Jobs3.setIndicator("", getApplicationContext().getResources().getDrawable(R.drawable.tab3)); 
     Intent JobsIntent3 = new Intent(this, Tab3Activity.class); 
     JobsIntent3.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); 
     Jobs3.setContent(JobsIntent3); 



     // Adding all TabSpec to TabHost 
     tabHost.addTab(Login); 
     tabHost.addTab(Jobs); 
     tabHost.addTab(Jobs3); 
    } 

C'est Tab2Activity.java

public class Tab2Activity extends TabActivity 
{ 



    @Override 
    protected void onCreate(Bundle savedInstanceState) 
    { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.tab2); 

     ///////////////////////// 

     TabHost tabHost2 = getTabHost(); 

     TabHost.TabSpec Gmapped = tabHost2.newTabSpec("InnerTabs"); 

     // setting Title and Icon for the Tab 
     Gmapped.setIndicator("", getApplicationContext().getResources().getDrawable(R.drawable.tab3)); 
     Intent GmappedIntent = new Intent(this, Tab3Activity.class); 
     GmappedIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); 
     Gmapped.setContent(GmappedIntent); 

     tabHost2.addTab(Gmapped); 
} 

et Tab2.xml

Je ne développe depuis longtemps, mais je comprends que je dois à TabHost à Tab2.xml, mais incertain étaient. Quelqu'un pourrait-il aider.

Si vous voulez un conseil, utilisez plutôt TabLayout, est plus facile:
