    }             
};

And I have decleared public static TabHost spec; in my TabActivity class still application is crashing.

This is my TabActivity Class.

 public class TabForConfiguration extends TabActivity {

 private Bundle bundle;      
 public static TabHost tabHost;      
 private TabHost.TabSpec tab1,tab2,tab3,tab4;     
 private Intent intentToTabOne,intentToTabtwo,intentToTabthree,intentToTabfour;      
 private int i=0,flagForTab,flagTest;     
 public int setTab=0,currentTabset;  

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    try{
    // request is for a window
    requestWindowFeature(Window.FEATURE_NO_TITLE);
    setContentView(R.layout.tab_for_configuration);
    Resources res = getResources();// resource for drawable
    tabHost = getTabHost(); // add tabs to tab host

    bundle = TabForConfiguration.this.getIntent().getExtras();                 
    setTab = bundle.getInt("setTab");                 
    flagTest = bundle.getInt("flag");                  

    if(flagTest == 0)                 
    {                     
        intentToTabOne= new Intent(TabForConfiguration.this,OwnerConfiguration.class);                     
        intentToTabOne.setFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);                 
    }  

    intentToTabtwo= new Intent(TabForConfiguration.this,RoomEdit.class);                 
    intentToTabthree= new Intent(TabForConfiguration.this,UserCreate.class);                 
    intentToTabfour= new Intent(TabForConfiguration.this,UserAccessRight.class); 
    //TabHost.TabSpec spec;

//  intent = new Intent().setClass(this, OwnerConfiguration.class);
    tab1 = tabHost
            .newTabSpec("Initializer")
            .setIndicator("Home_Configure",
                    res.getDrawable(R.drawable.config_home))
            .setContent(intentToTabOne);
    tabHost.addTab(tab1);

    tab2 = tabHost
            .newTabSpec("Room Edit")
            .setIndicator("Room_Edit",res.getDrawable(R.drawable.room_edit))
            .setContent(intentToTabtwo);
    tabHost.addTab(tab2);

    tab3 = tabHost
            .newTabSpec("User Create")
            .setIndicator("User_Create",res.getDrawable(R.drawable.user_info))
            .setContent(intentToTabthree);
    tabHost.addTab(tab3);

    tab4 = tabHost.newTabSpec("Room Access")
            .setIndicator("Room_Right", res.getDrawable(R.drawable.right))
            .setContent(intentToTabfour);
    tabHost.addTab(tab4);




if(setTab == 0)                 
{                     
    currentTabset = 0;                     
    tabHost.setCurrentTab(currentTabset);                 
}                 
else if(setTab == 1)                 
{                     
    currentTabset = 1;                     
    tabHost.setCurrentTab(currentTabset);                 
}                 
else if(setTab == 2)                 
{                     
    currentTabset = 2;                     
    tabHost.setCurrentTab(currentTabset);                 
}                 
else if(setTab == 3)                 
{                     
    currentTabset = 3;                     
    tabHost.setCurrentTab(currentTabset);                 
}                 
else if(setTab == 4)                 
{                     
    currentTabset = 4;                     
    tabHost.setCurrentTab(currentTabset);                 
} 
    }

    finally
    {

    }
}   
  }

Answer 1

after click on button set that tab.So that tab will not disappeared.
Also in tab activity set

 public static TabHost tabHost;` 
 Button b1 = new Button(this);
b1.setOnClickListener(new OnClicklistener()  
{
public void onClick(View v) 
                {
Tabs.tabHost.setCurrentTab(1);
}
});

Now your tabs will present there. Tabs is my tabactivity.
