tab bar hiding issue android

问题

I'm new to android,I'm using tabHost adding some tabs to it,its working quite fine but when i rotate my device in landscape mode it also work there fine but i don't need tab bar there because it covers much space and i also have google ads so both of them cover half of the screen and leave a little space for user to interact.All i need is a solution to somehow hide tab bar just like we can do it in iphone to make a bit room for user to interact.I need some solution urgent.Thanks

I think you should wrap your tab widget in any ViewGroup such as LinearLayout or RelativeLayout, and create a static function in your tabActivity to show/hide this wrapper, Here's a little code might be helpful for you.

<LinearLayout
        android:id="@+id/popupTabs"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:visibility="gone">
        <TabWidget android:id="@android:id/tabs"
        android:layout_height="wrap_content" 
        android:layout_width="fill_parent"></TabWidget>
    </LinearLayout>

Now your tab activity should do something like this.

public class TabsView extends TabActivity { 
    public static LinearLayout popupTabs ;

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        popupTabs = (LinearLayout) findViewById(R.id.popupTabs);

        // Your other code
        //............
        //............
    }

    // Show Tabs method
    public static void showTabs(){
        popupTabs.setVisibility(ViewGroup.VISIBLE);
    }

    // Hide Tabs method
    public static void hideTabs(){
        popupTabs.setVisibility(ViewGroup.GONE);
    }

}

Now you can call this method statically from any location in your code like this

// hide tab from any activity
TabsView.showTabs();

// hide tab from any activity
TabsView.hideTabs()

For Hide

mTabHost.getTabWidget().setVisibility(View.GONE);

For Visible

mTabHost.getTabWidget().setVisibility(View.VISIBLE);

The simplest way would be to create a second version of your layout.xml file which doesn't include the TabHost and put it in a resource folder named 'layout-land' (the 'land' suffix is short for 'landscape'). Please see this SDK article for more information.

Apart from doing what Reuben is telling you would be to animate the transition between both so that the change would be a bit smoother.
