Android: tabhost with more intent than tabs
===

here's my questions:
i have a normal tabactivity, with my three tabs defined like this one:

        TabSpec listatabs= tabHost.newTabSpec("App");
        listatabs.setIndicator("Lista", getResources().getDrawable(R.drawable.mia_lista));
        Intent listaIntent = new Intent(this, MIALISTA.class);
        listaIntent .addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
        listatabs.setContent(listaIntent );
        // Aggiungo i tabs
        tabHost.addTab(listatabs);

the problem is: if the user go in this tab (which have a list of items), and click on a item, i must call a new intent to display the content (and of course a new .class)... but i must remain in the intrested tab.
how can i implement this idea?
