This is what i do to the First Activity Code:

public void OnClickRanoNews(View v)
    {
        if (v.getId() == R.id.btnRanoNews)
        {
            Intent i = new Intent(this, RanoNews.class);
            i.putExtra("msg","0");
            startActivity(i);

        }

    }
    public void OnClickRanoNews2(View v)
    {
            if(v.getId()== R.id.btnRanoNews2)
            {
                Intent i = new Intent(this, RanoNews.class);
                i.putExtra("msg","1");
                startActivity(i);

            }
    }

Second Activity Code:

tabHost = (TabHost)findViewById(R.id.tabHost);
        tabHost.setup();
        TabHost.TabSpec
        tabSpec  = tabHost.newTabSpec("rano news");
        tabSpec.setContent(R.id.tabRanoNews);
        tabSpec.setIndicator("Rano News");
        tabHost.addTab(tabSpec);

        tabSpec  = tabHost.newTabSpec("adding form");
        tabSpec.setContent(R.id.tabAddingForm);
        tabSpec.setIndicator("Adding Form");
        tabHost.addTab(tabSpec);

        if(getIntent()!=null)
        {
            if(getIntent().getStringExtra("msg").equals("0"))
                tabHost.getTabWidget().getChildTabViewAt(1).setEnabled(true);

            else if (getIntent().getStringExtra("msg").equals("1"))
                tabHost.getTabWidget().getChildTabViewAt(1).setVisibility(View.GONE);
        }

Just pass additional extra parameter to new activity (in Bundle)

    if (v.getId() == R.id.btnRanoNews2) {
        Intent i = new Intent(this, RanoNews.class);
        i.putExtra(RanoNews.TABHOST_ENABLED, false /* put your value here */);
        startActivity(i);
    }

And handle it in new activity as last line of onCreate() method

    public static final String TABHOST_ENABLED = "tabhost_enabled";

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        /* TabHost initialization */

        if (getIntent().getExtras() != null) {
            boolean isEnabled = getIntent().getExtras().getBoolean(TABHOST_ENABLED);
            tabHost.setEnabled(isEnabled);
        }
    }

        {
            Intent i = new Intent(this, RanoNews.class); 
            i.putExtra("msg", "0");
            startActivity(i);
        }
}

on the second Activity

if(getIntent() != null){
      if(getIntent().getStringExtra("msg").equals("0")){
         tabHost.getTabWidget().getChildTabViewAt(1).setEnabled(true);
     }
}
