你可以定义主题，使用样式来实现:

You can define themes, use styles to achieve this:

首先在 res/values/styles.xml 中为 Activity 创建主题(名称:CustomTheme):

First you create the theme (name:CustomTheme) for your Activity in your res/values/styles.xml:

<style name="CustomTheme" parent="@android:style/Theme">
    <item name="android:tabWidgetStyle">@style/CustomTabWidget</item>
</style>
<style name="CustomTabWidget" parent="@android:style/Widget.TabWidget">
    <item name="android:textAppearance">@style/CustomTabWidgetText</item>
</style>
<style name="CustomTabWidgetText" 
    parent="@android:style/TextAppearance.Widget.TabWidget">
    <item name="android:textSize">20sp</item>
    <item name="android:textStyle">bold</item>
</style>

然后在您的 androidManifest.xml 中为包含您的 TabWidget 的 TabActivity 或 Activity 指定上述主题:

Then in your androidManifest.xml you specify the theme above for your TabActivity or Activity containing your TabWidget:

<activity android:name="MyTabActivity" android:theme="@style/CustomTheme">

这将为您提供所需的输出(当然，您应该根据自己的喜好更改大小和样式).

This will serve you with the output you want (of course you should change the size and style for your preference).
