记录器和播放器有两个选项卡。在它没有问题之前，但在我添加了横向布局之后就变成了这样。

试试这段代码：

    public class MainActivity extends Activity {

    @Override
    public void onCreate(final Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.awesome_tabbed_layout);

        // Standard tabbed navigation setup.
        final ActionBar actionBar = getActionBar();
        actionBar.setDisplayShowTitleEnabled(true);
        actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);

        // ...
        // Create tabs, fragments, pager and anything else needed.
        // ...

        forceTabs(); // Force tabs when activity starts.
    }

    @Override
    public void onConfigurationChanged(final Configuration config) {
        super.onConfigurationChanged(config);
        forceTabs(); // Handle orientation changes.
    }

    // This is where the magic happens!
    public void forceTabs() {
        try {
            final ActionBar actionBar = getActionBar();
            final Method setHasEmbeddedTabsMethod = actionBar.getClass()
                .getDeclaredMethod("setHasEmbeddedTabs", boolean.class);
            setHasEmbeddedTabsMethod.setAccessible(true);
            setHasEmbeddedTabsMethod.invoke(actionBar, true);
        }
        catch(final Exception e) {
            // Handle issues as needed: log, warn user, fallback etc
            // This error is safe to ignore, standard tabs will appear.
        }
    }

}
