Change text on Android tab

Question

I have an Android application with 3 tabs in TabHost (text labels, no images). I set up the tabs like this:

intent = new Intent().setClass(this, AnnouncementsActivity.class);
spec = tabHost.newTabSpec("news").setIndicator("News").setContent(intent);
tabHost.addTab(spec);

I am running a background thread to retrieve ads from my server, and I want to update the text label on the tab to tell the user how many new ads there are. For example, I want to change the text on the tab to "News (3)". How can I access and change the text label on a tab?

Any suggestions are welcome!

TabHost, , .

Please excuse my English, I'm Brazilian and I'm still studying. I hope to help someone who has the same problem.

TabHost host = (TabHost)findViewById(R.id.tabDetail);
    host.setup();

    //Tab 1
    TabHost.TabSpec spec = host.newTabSpec("tab1");
    spec.setContent(R.id.tab1);
    spec.setIndicator("Details");
    host.addTab(spec);

    //Tab 2
    spec = host.newTabSpec("tab2");
    spec.setContent(R.id.tab2);
    spec.setIndicator("Comments");
    host.addTab(spec);
