<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">
<LinearLayout
    android:id="@+id/tab"    android:orientation="vertical"        android:layout_width="fill_parent"   android:layout_height="fill_parent">
    <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">

        <LinearLayout android:id="@+id/tab1" android:layout_width="fill_parent"

TestActivity.java

setContentView(R.layout.maiin);  
         final TabHost tabHost = (TabHost) getTabHost();
            tabHost.addTab(createTab(MobiintheMorningActivity.class, 
                    "Welcome", "Welcome", R.drawable.icon));
            tabHost.addTab(createTab(SongList.class, 
                    ".Mp3List", ".Mp3List", R.drawable.icon));
            tabHost.addTab(createTab(AboutUs.class, 
                    "AboutUs", "AboutUs", R.drawable.icon));
            tabHost.addTab(createTab(ExtraInfromation.class, 
                    "Extra", "Extra", R.drawable.icon));


            tabHost.setCurrentTab(0);
            tabHost.getTabWidget().getChildAt(0).getLayoutParams().width = 85;
            tabHost.getTabWidget().getChildAt(1).getLayoutParams().width = 85;
            tabHost.getTabWidget().getChildAt(2).getLayoutParams().width = 85;
            tabHost.getTabWidget().getChildAt(3).getLayoutParams().width = 85;        
        }
        private TabSpec createTab(final Class<?> intentClass, final String tag, 
                final String title, final int drawable)
        {
            final Intent intent = new Intent().setClass(this, intentClass);

            final View tab = LayoutInflater.from(getTabHost().getContext()).
                inflate(R.layout.tab, null);
            ((TextView)tab.findViewById(R.id.tab_text)).setText(title);
            ((ImageView)tab.findViewById(R.id.tab_icon)).setImageResource(drawable);

            return getTabHost().newTabSpec(tag).setIndicator(tab).setContent(intent);
        }
    }

这是完整的工作代码：Pragna
