public void OnClickRanoNews2(View v)
{
        if(v.getId()== R.id.btnRanoNews2)
        {
            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);
     }
}
