使用支持库(ActionBarSherlock)在Android 4中嵌套选项卡

public class NestedTabsActivity extends SherlockFragmentActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_nested_tabs);

        ActionBar actionBar = getSupportActionBar();
        actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);

        ActionBar.Tab tab1 = actionBar.newTab();
        tab1.setText("Tab 1");
        tab1.setTabListener(new TabListener<Tab1Fragment>(this, "tab1", Tab1Fragment.class));
        actionBar.addTab(tab1);

        ActionBar.Tab tab2 = actionBar.newTab();
        tab2.setText("Tab 2");
        tab2.setTabListener(new TabListener<Tab2Fragment>(this, "tab2", Tab2Fragment.class));
        actionBar.addTab(tab2);
    }

    public static class Tab1Fragment extends SherlockFragment {

        @Override
        public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
            View view = inflater.inflate(R.layout.fragment_tab1, container, false);

            return view;
        }
    }

    public static class Tab2Fragment extends SherlockFragment {

        @Override
        public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
            View view = inflater.inflate(R.layout.fragment_tab2, container, false);

            return view;
        }
    }
}
