就我而言，我切换到AndroidX工具栏，而不是使用本机操作栏。此外，我依赖于视图绑定从活动访问工具栏，但您可以使用findViewById(…)。

(我删除了不相关的代码)。

styles.xml:

...
<style name="AppTheme" parent="Theme.MaterialComponents.Light.NoActionBar">
  ...
</style>
...

activity_main.xml:

...
<androidx.appcompat.widget.Toolbar
  android:id="@+id/toolbarMain"
  android:theme="@style/ThemeOverlay.AppCompat.ActionBar"
  app:titleTextColor="@color/colorOnPrimary"
  ...
/>
...

MainActivity.kt:

class MainActivity : AppCompatActivity() {

  private lateinit var binding: ActivityMainBinding
  ...

  override fun onCreate(savedInstanceState: Bundle?) {
    ...
    binding = DataBindingUtil.setContentView(this, R.layout.activity_main)
    setSupportActionBar(binding.toolbarMain)
    ...
  }

  ...
}

将它添加到操作栏的根。我有这个问题。

<style name="ActionBar" parent="@style/Theme.AppCompat.Light">
    <item name="actionBarStyle">@style/Widget.Styled.ActionBar</item>
    <item name="actionMenuTextColor">@color/stdDarkBlueText</item>
</style>

<style name="Widget.Styled.ActionBar" parent="@style/Widget.AppCompat.Light.ActionBar">
    <item name="titleTextStyle">@style/ActionBarTitleText</item>
    <item name="subtitleTextStyle">@style/ActionBarSubTitleText</item>
</style>

<style name="ActionBarTitleText" parent="@style/TextAppearance.AppCompat.Widget.ActionBar.Title">
    <item name="android:textColor">@color/stdDarkBlueText</item>
    <item name="android:textSize">12sp</item>
</style>

<style name="ActionBarSubTitleText" parent="@style/TextAppearance.AppCompat.Widget.ActionBar.Subtitle">
    <item name="android:textColor">@color/stdDarkBlueText</item>
    <item name="android:textSize">12sp</item>
</style>

actionMenuTextColor -更改操作栏文本的颜色，当它是Widget.Styled的一部分时，它从未工作过。ActionBar，所以我必须把它添加到根目录中。其他2个属性更改操作栏的标题和副标题。

找到了一种方法，可以很好地做到这一点，而无需在API >= 21上创建自己的布局。

它只会在操作栏中对文本和控件绘图进行着色。

希望对别人有用。

<!--Material design primary colors-->
<style name="AppBaseTheme" parent="Theme.AppCompat.Light">
    <item name="colorPrimary">@color/primary</item>
    <item name="colorPrimaryDark">@color/primary_dark</item>
    <item name="colorAccent">@color/accent</item>
    <item name="android:navigationBarColor">@color/primary_dark</item>
    <item name="actionBarTheme">@style/AppBaseTheme.Toolbar</item>
</style>

<!--Action bar-->
<style name="AppBaseTheme.Toolbar" parent="Widget.AppCompat.ActionBar.Solid">
    <item name="android:textColorPrimary">@color/action_bar_text</item>
    <item name="colorControlNormal">@color/action_bar_text</item>
</style>

我已经用简单的一行代码完成了

actionBar.setTitle(Html.fromHtml("<font color='#ff0000'>ActionBartitle </font>"));

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!

<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>
 
  <!-- android:textColorPrimaryInverse is the  color of the title
       text in the Toolbar, in the Theme.AppCompat.Light theme:  -->
  <!-- <item name="android:textColorPrimaryInverse">@color/abc_primary_text_material_light</item> -->
 
  <!-- 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>
