这是一个老话题，但对于未来的读者来说，使用工具栏使一切变得非常简单:

Toolbar toolbar = (Toolbar) findViewById(R.id.tool_bar);
toolbar.setTitle(R.string.app_name);
toolbar.setTitleTextColor(getResources().getColor(R.color.someColor));
setSupportActionBar(toolbar);

我发现了一种适用于任何类型的ActionBar (Sherlock, Compat和Native)的方法:

只需使用html设置标题，并指定文本颜色。例如，要将ActionBar文本颜色设置为红色，只需这样做:

getActionBar()/* or getSupportActionBar() */.setTitle(Html.fromHtml("<font color=\"red\">" + getString(R.string.app_name) + "</font>"));

你也可以使用红色十六进制代码#FF0000来代替单词red。如果你对此有问题，请参阅Android Html.fromHtml(String)不适用于<font color='#'>text</font>。

此外，如果你想使用颜色资源，这段代码可以用来获得正确的HEX字符串，并在需要时删除alpha(字体标签不支持alpha):

int orange = getResources().getColor(R.color.orange);
String htmlColor = String.format(Locale.US, "#%06X", (0xFFFFFF & Color.argb(0, Color.red(orange), Color.green(orange), Color.blue(orange))));

ActionBar ID不是直接可用的，所以你必须做一点hack。

int actionBarTitleId = Resources.getSystem().getIdentifier("action_bar_title", "id", "android");
if (actionBarTitleId > 0) {
    TextView title = (TextView) findViewById(actionBarTitleId);
    if (title != null) {
        title.setTextColor(Color.RED);
    }
}

<android.support.v7.widget.Toolbar
  xmlns:android="http://schemas.android.com/apk/res/android"
  xmlns:app="http://schemas.android.com/apk/res-auto"
  android:id="@+id/toolbar"
  android:layout_width="match_parent"
  android:layout_height="wrap_content"
  android:background="@color/color_primary"
  android:theme="@style/GalaxyZooThemeToolbarDarkOverflow"
  app:popupTheme="@style/Theme.AppCompat.NoActionBar" />


<style name="GalaxyZooThemeToolbarDarkOverflow" parent="Theme.AppCompat.NoActionBar">
  <!-- android:textColorPrimary is the  color of the title text
       in the Toolbar, in the Theme.AppCompat theme:  -->
  <item name="android:textColorPrimary">@color/abc_primary_text_material_light</item>

       text in the Toolbar, in the Theme.AppCompat.Light theme:  -->

  <!-- android:actionMenuTextColor is the color of the text of
        action (menu) items in the Toolbar, at least in the
        Theme.AppCompat theme.
        For some reason, they already get the textColorPrimary
        when running on API 21, but not on older versions of
        Android, so this is only necessary to support older
        Android versions.-->
        <item name="actionMenuTextColor">@color/abc_primary_text_material_light</item>
  <!-- android:textColorSecondary is the color of the menu
       overflow icon (three vertical dots) -->
  <item name="android:textColorSecondary">@color/abc_secondary_text_material_light</item>
 
  <!-- This would set the toolbar's background color,
        but setting this also changes the popup menu's background,
        even if we define popupTheme for our <Toolbar> -->
  <!-- <item name="android:background">@color/color_primary</item> -->
</style>

我和你有同样的问题，是Holo。轻主题，但我想样式的动作栏的颜色，所以我需要改变文本的颜色以及标题和菜单。所以最后我去了git中心，查看源代码，直到我找到了该死的正确风格:

<?xml version="1.0" encoding="utf-8"?>
<!-- For honeycomb and up -->
<resources>

    <style name="myTheme" parent="@android:style/Theme.Holo.Light">
        <item name="android:actionBarStyle">@style/myTheme.ActionBar</item>
        <item name="android:actionMenuTextColor">@color/actionBarText</item>
    </style>

    <style name="myTheme.ActionBar" parent="@android:style/Widget.Holo.Light.ActionBar">
        <item name="android:background">@drawable/actionbarbground</item>
        <item name="android:titleTextStyle">@style/myTheme.ActionBar.Text</item>
    </style>

    <style name="myTheme.ActionBar.Text" parent="@android:style/TextAppearance">
        <item name="android:textColor">@color/actionBarText</item>
    </style>

</resources>

所以现在你要做的就是设置任何@color/actionBarText and@drawable/actionbarbground你想要!

最直接的方法是在styles.xml中完成。

谷歌的模板styles.xml当前生成以下内容:

<style name="AppTheme" parent="Theme.AppCompat.Light">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
</style>

如果你在结束标签之前再添加一行，如图所示，这将改变文本的颜色，使其与Dark ActionBar相同:

<style name="AppTheme" parent="Theme.AppCompat.Light">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
    <item name="actionBarTheme">@style/ThemeOverlay.AppCompat.Dark.ActionBar</item>
</style>

如果你想自定义颜色为其他东西，你可以在colors.xml中指定自己的颜色，甚至使用Android的内置颜色使用Android:textColorPrimary属性:

<style name="AppTheme" parent="Theme.AppCompat.Light">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
    <item name="actionBarTheme">@style/AppTheme.AppBarOverlay</item>
</style>


<style name="AppTheme.AppBarOverlay" parent="ThemeOverlay.AppCompat.Dark.ActionBar">
    <item name="android:textColorPrimary">@android:color/darker_gray</item>
</style>

注意:这将改变标题的颜色，以及在动作栏中显示的任何菜单项的标题。
