Android中的标签无法正常工作？

Question

I have created 4 tabs in my application using tabHost , it working fine. below i show my code for adding only 2 tabs.

           public class Home_tab extends TabActivity {


public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.home_main);

    Resources ressources = getResources(); 
    TabHost tabHost = getTabHost(); 

    // Android tab

    Intent intentAndroid = new Intent().setClass(this, CoalActivity.class);
    TabSpec tabSpecAndroid = tabHost


      .newTabSpec("Android")

      .setIndicator("", ressources.getDrawable(R.drawable.tab_dis))
      .setContent(intentAndroid);

    // Apple tab
    Intent intentApple = new Intent().setClass(this, EnergyActivity.class);
    TabSpec tabSpecApple = tabHost
      .newTabSpec("Apple")

      .setIndicator("", ressources.getDrawable(R.drawable.tab_foc))
      .setContent(intentApple);


    // add all tabs 
    tabHost.addTab(tabSpecAndroid);
    tabHost.addTab(tabSpecApple);

                }
              }

This is my xml file

       <?xml version="1.0" encoding="utf-8"?>
      <TabHost xmlns:android="http://schemas.android.com/apk/res/android"
         android:id="@android:id/tabhost"
         android:layout_width="fill_parent"
         android:layout_height="fill_parent"
         android:background="@drawable/background"
         android:scrollbarAlwaysDrawHorizontalTrack="true"
        >
<LinearLayout
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:padding="5dp">
    <TabWidget
        android:id="@android:id/tabs"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content" />
    <FrameLayout
        android:id="@android:id/tabcontent"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:padding="5dp" />
  </LinearLayout>
  </TabHost>

But my problem is when i add more tabs, it comes in the same window. for example, currently i added 4 tabs, when i try to add 3 more tabs , all the tabs are coming in the same window? i want to add only 4 tabs in the same window, other tabs should appears only when i scroll the tab bar How to solve this??
