Отъезд Hello, TabWidget.

Answer 2

я сделал tabhost связанного код с относительно отображающей оценки

TabHost host = getTabHost(); 
    host.setup(); 

    TabSpec allScoresTab = host.newTabSpec("allTab"); 
    allScoresTab.setIndicator(getResources().getString(R.string.all_scores), getResources().getDrawable(android.R.drawable.star_on)); 
    allScoresTab.setContent(R.id.ScrollViewAllScores); 
    host.addTab(allScoresTab); 

    TabSpec friendScoresTab = host.newTabSpec("friendsTab"); 
    friendScoresTab.setIndicator(getResources().getString(R.string.friends_scores), getResources().getDrawable(android.R.drawable.star_on)); 
    friendScoresTab.setContent(R.id.ScrollViewFriendScores); 
    host.addTab(friendScoresTab); 

    host.setCurrentTabByTag("allTab");

activity_main.xml содержит

<?xml version="1.0" encoding="utf-8"?> 
<TabHost xmlns:android="http://schemas.android.com/apk/res/android" 
    android:id="@android:id/tabhost"

    android:layout_height="match_parent" > 

    <RelativeLayout 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" > 

     <FrameLayout 
      android:id="@android:id/tabcontent" 
      android:layout_width="match_parent"

     </HorizontalScrollView>

</TabHost> 

и Java-код

TabHost tabHost = getTabHost(); 

     TabSpec spec; 

     Intent intent; 

     //Home Tab 
     View view1 = LayoutInflater.from(MainActivity.this).inflate(R.layout.home, null); 

     intent = new Intent(MainActivity.this, Firstclass.class); 

     spec = tabHost.newTabSpec("HOME").setIndicator(view1) 
       .setContent(intent); 

     tabHost.addTab(spec); 

     //Calendar Tab 
     View view2 = LayoutInflater.from(MainActivity.this).inflate(R.layout.calendar_tab, null); 

     intent = new Intent(MainActivity.this, Calendar.class); 

     spec = tabHost.newTabSpec("CALENDAR").setIndicator(view2)
