效果图

activity_tabhost.xml：

<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"
    android:background="#0ef"
    android:orientation="vertical">
    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical">
    <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>
</TabHost>

MainActivity.java:

public class IntentTabActivity extends TabActivity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_tabhost);
        TabHost tabHost=getTabHost();
        tabHost.addTab(tabHost.newTabSpec("tab1").setIndicator("已接电话").setContent(new Intent(this,BeCalledActivity.class)));
        tabHost.addTab(tabHost.newTabSpec("tab1").setIndicator("呼出电话").setContent(new Intent(this,CalledActivity.class)));
        tabHost.addTab(tabHost.newTabSpec("tab1").setIndicator("未接电话").setContent(new Intent(this,NoCallActivity.class)));
    }
}

其他三个Activity就只是显示两个TextView,这里省略不写
