3 つのタブを追加しましたが、使用に問題はありません。スクロール可能にしたい場合は <HorizontalScrollView>
、親として<TabWidget>
mainActivity.xmlに追加するだけです。
<?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="match_parent"
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"
android:layout_height="match_parent"

<TabWidget
