TabWidget will not display, even though it displays in ADT editor

Question

My TabWidget will not display, even though it shows up in the Eclipse graphical editor. I can't find any reason why. Why isn't my tab bar showing?

Eclipse

Emulator

XML source of the activity: http://pastebin.com/Au9XFXPa

Extract from activity:

        <TabWidget
            android:id="@android:id/tabs"
            android:layout_width="match_parent"
            android:layout_height="wrap_content" >
        </TabWidget>

Results from Android lint:

$ lint.bat res/layout/activity_calculator.xml

No issues found.

It's hard to tell without actual code of how your activity is implemented, but seems like you need to call setContent() on your TabHost:

    TabHost tabs = (TabHost)findViewById(R.id.tabhost);
    tabs.setup();

    // Calculator
    TabHost.TabSpec calculatorTab = tabs.newTabSpec("calculator");
    calculatorTab.setContent(R.id.calculator);
    calculatorTab.setIndicator("Calculator");
    tabs.addTab(calculatorTab);

    // Home
    TabHost.TabSpec homeTab = tabs.newTabSpec("home");
    homeTab.setContent(R.id.home);
    tabs.addTab(homeTab);

    // Home
    TabHost.TabSpec faqTab = tabs.newTabSpec("faq");
    faqTab.setContent(R.id.faq);
    tabs.addTab(faqTab);

This should give you the idea.
