Tabs in Android not working correctly?

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??

there're good reasons why the TabHost is deprecated. It doesn't work very well, it's not flexible enough, it's difficult to implement. On this link you can see how easy is to implement tabs in the actionbar: http://developer.android.com/guide/topics/ui/actionbar.html#Tabs — Budius, Mar 06 '13 at 09:34

Check this link out for help http://stackoverflow.com/questions/5799320/android-remove-space-between-tabs-in-tabwidget?rq=1 You can give tabs width also like tabHost.getTabWidget().getChildAt(0).getLayoutParams().width = 140; – Abhinav Singh Maurya Mar 06 '13 at 11:01
