这些函数运行良好

在Java中

private void setActionbarTextColor(ActionBar actBar, int color) {

    String title = actBar.getTitle().toString();
    Spannable spannablerTitle = new SpannableString(title);
    spannablerTitle.setSpan(new ForegroundColorSpan(color), 0, spannablerTitle.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
    actBar.setTitle(spannablerTitle);

}

然后使用它只需输入你的动作栏和新的颜色。

ActionBar actionBar = getActionBar();    // Or getSupportActionBar() if using appCompat
int red = Color.RED
setActionbarTextColor(actionBar, red);

在Kotlin

你可以像这样使用扩展函数:

private fun ActionBar.setTitleColor(color: Int) {
    val text = SpannableString(title ?: "")
    text.setSpan(ForegroundColorSpan(color),0,text.length, Spannable.SPAN_INCLUSIVE_INCLUSIVE)
    title = text
}

然后应用到你的动作栏

actionBar?.setTitleColor(Color.RED)

<android.support.v7.widget.Toolbar

  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>

        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>

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!

很多答案已弃用，所以我将更新线程，并展示如何在ActionBar(工具栏)和ActionBar弹出菜单中更改文本颜色和背景色。

在Android中(截至2018年5月)使用操作栏(工具栏)的最新方法是使用主题和NoActionBar，而不是使用工具栏。

这就是你所需要的:

In Activity (which extends AppCompatActivity) declare Toolbar: Toolbar myToolbar = (Toolbar) findViewById(R.id.toolbar); setSupportActionBar(myToolbar); Add Toolbar in the Activity's layout xml. Here we will set our custom (overwritten themes), note android:theme="@style/ThemeOverlay.AppTheme.ActionBar" and app:popupTheme="@style/ThemeOverlay.AppTheme.PopupMenu", they will do the trick. <android.support.v7.widget.Toolbar android:id="@+id/toolbar" android:layout_width="match_parent" android:layout_height="wrap_content" android:minHeight="?attr/actionBarSize" android:theme="@style/ThemeOverlay.AppTheme.ActionBar" app:popupTheme="@style/ThemeOverlay.AppTheme.PopupMenu" app:layout_constraintTop_toTopOf="parent" /> In your styles.xml you will have to overwrite those two styles to set custom colors: <style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar"> <!-- 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.AppTheme.ActionBar</item> <item name="actionBarPopupTheme">@style/ThemeOverlay.AppTheme.PopupMenu</item> </style> <style name="ThemeOverlay.AppTheme.ActionBar" parent="ThemeOverlay.AppCompat.Dark.ActionBar"> <item name="android:textColorPrimary">@color/action_bar_text_color</item> <item name="android:background">@color/action_bar_bg_color</item> </style> <style name="ThemeOverlay.AppTheme.PopupMenu" parent="ThemeOverlay.AppCompat.Dark.ActionBar"> <item name="android:background">@color/popup_bg_color</item> <item name="android:textColorPrimary">@color/popup_text_color</item> </style>

就是这样，伙计们

附注:如果你问我，我会说:是的，整个主题的事情是一团糟。

您可以直接在XML文件中使用HTML <font>属性更改任何文本的颜色。 例如在strings.xml中:

<resources>
    <string name = "app_name">
        <html><font color="#001aff">Multi</font></html>
        <html><font color="#ff0044">color</font></html>
        <html><font color="#e9c309">Text </font></html>
    </string>
</resources>
