Style it in your custom theme change
在您的自定义主题更改中设置样式
<item name="android:tabWidgetStyle">@android:style/Widget.TabWidget</item>
and
和
<style name="Widget.TabWidget">
<item name="android:textAppearance">@style/TextAppearance.Widget.TabWidget</item>
<item name="android:ellipsize">marquee</item>
<item name="android:singleLine">true</item>
</style>
<style name="TextAppearance.Widget.TabWidget">
<item name="android:textSize">14sp</item>
<item name="android:textStyle">normal</item>

Here is a new answer I found from Fred Grott (http://knol.google.com/k/fred-grott/advance-tabs/) after a little web searching.
This lets you set a selectorfor text color so a different color can be used when tab is selected or not. Which can be very useful if you are using a different background color for the tab if its selected. Of course you can also just throw in a plain color and not a selector.
这是我在网上搜索后从 Fred Grott ( http://knol.google.com/k/fred-grott/advance-tabs/)找到的新答案。
这使您可以设置selector文本颜色，以便在选择或不选择选项卡时可以使用不同的颜色。如果您为选项卡使用不同的背景颜色（如果它被选中），这将非常有用。当然，您也可以只使用纯色而不是选择器。
final TextView tv = (TextView) tabWidget.getChildAt(i).findViewById(android.R.id.title);
tv.setTextColor(this.getResources().getColorStateList(R.color.text_tab_indicator));
Where R.color.text_tab_indicator is a selector xml filelocated in your res/drawable folder.
In other words, the indicator text really is a TextViewwhich is retrievable via the Viewobject which can be accessed from the TabWidgetobject.
Take a look at Fred's examples for more info and context regarding the variable declarations as well as other tricks.
其中 R.color.text_tab_indicator 是位于 res/drawable 文件夹中的选择器 xml 文件。
换言之，指示符文本实际上是可通过可从对象访问的对象TextView检索View的TabWidget。
查看 Fred 的示例，了解有关变量声明以及其他技巧的更多信息和上下文。

Danny C's answer is 100% correct.I just wanted to add something to it to make a complete answer with resource file.
Danny C 的回答是 100% 正确的。我只是想添加一些东西来用资源文件做出一个完整的答案。
The text_tab_indicator under res/color file
res/color文件下的text_tab_indicator
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:textColor="@color/text_tab_selected"
android:state_selected="true" />
<item android:textColor="@color/text_tab_unselected"
android:state_selected="false" />
</selector>
And this text_tab_unselected & text_tab_selected will look like this under colors/values folder
这个 text_tab_unselected & text_tab_selected 在颜色/值文件夹下看起来像这样
<resources>
<color name="text_tab_selected">#ffffff</color>
<color name="text_tab_unselected">#95ab45</color>
After that finally add Dannyy's answer in tab class file
之后最后在选项卡类文件中添加丹尼的答案
final TextView tv = (TextView) tabWidget.getChildAt(i).findViewById(android.R.id.title);
tv.setTextColor(this.getResources().getColorStateList(R.color.text_tab_indicator));

The change in color can also be stated without using java - which is probably better.
不使用 java 也可以说明颜色的变化 - 这可能更好。
I made changes to the text_tab_indicator (notice textColor was changed to 'color'):
我对 text_tab_indicator 进行了更改（注意 textColor 已更改为 'color'）：
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_selected="true" android:color="@color/text_tab_selected" />
<item android:state_selected="false" android:color="@color/text_tab_unselected" />
</selector>
Set the style of the TabWidget to point to a specific style in your xml code:
将 TabWidget 的样式设置为指向 xml 代码中的特定样式：
<TabWidget
...
style="@style/TabText"
/>
Declare your text_tab_indicator located in /res/color as you desired color in the style
将位于 /res/color 中的 text_tab_indicator 声明为您想要的样式颜色
<style name="TabText">
<item name="android:textColor">@color/tab_text_color</item>
</style>
It worked like a charm (for me).
它就像一个魅力（对我来说）。

干杯，兰德尔
