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


my tabwidget not display, though shows in eclipse graphical editor. can't find reason why. why isn't tab bar showing?

eclipse

emulator

xml source of activity: http://pastebin.com/au9xfxpa

extract activity:

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

results android lint:

$ lint.bat res/layout/activity_calculator.xml scanning catalyst: . no issues found.

it's hard tell without actual code of how activity implemented, seems need call setcontent() on 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 idea.
