正如你在这个问题中看到的，你应该:

<item name="android:textColorPrimary">yourColor</item>

上面的代码更改API >= v21菜单操作项的文本颜色。

<item name="actionMenuTextColor">@android:color/holo_green_light</item>

以上是API < v21的代码

如果你使用的菜单是<android.support.design.widget.NavigationView />，那么只需在NavigationView中添加以下一行:

app:itemTextColor="your color"

也可用colorTint图标，它将覆盖颜色为您的图标以及。为此，你必须添加以下一行:

app:itemIconTint="your color"

例子:

<android.support.design.widget.NavigationView
        android:id="@+id/nav_view"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:layout_gravity="start"

        app:itemTextColor="@color/color_white"
        app:itemIconTint="@color/color_white"

        android:background="@color/colorPrimary"
        android:fitsSystemWindows="true"
        app:headerLayout="@layout/nav_header_main"
        app:menu="@menu/activity_main_drawer"/>

希望对你有所帮助。

我的情况是在选项菜单中设置文本颜色(主应用程序菜单显示在菜单按钮按下)。

在API 16中测试，使用AppCompat -v7-27.0.2库，MainActivity的AppCompat活动和AndroidManifest.xml应用程序的AppCompat主题。

styles.xml:

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
  <item name="actionBarPopupTheme">@style/PopupTheme</item>
</style>

<style name="PopupTheme" parent="@style/ThemeOverlay.AppCompat.Light">
  <item name="android:textColorSecondary">#f00</item>
</style>

不知道textColorSecondary是否影响其他元素，但它控制菜单文本的颜色。

我搜索了一些关于这个主题的示例，但所有现成的代码片段都不起作用。

所以我想用appcompat-v7库的源代码(特别是.aar包的res文件夹)来研究它。

不过在我的例子中，我使用了带有爆炸性.aar依赖项的Eclipse。因此，我可以更改默认样式并检查结果。不知道如何爆炸库与Gradle或Android Studio直接使用。它值得进行另一项调查。

所以我的目的是找到res/values/values.xml文件中用于菜单文本的颜色(我几乎确定颜色在那里)。

I opened that file, then duplicated all colors, put them below the default ones to override them and assigned #f00 value to all of them. Start the app. Many elements had red background or text color. And the menu items too. That was what I needed. Removing my added colors by blocks of 5-10 lines I ended with the secondary_text_default_material_light color item. Searching that name in the files within the res folder (or better within res/colors) I found only one occurrence in the color/abc_secondary_text_material_light.xml file (I used Sublime Text for these operations so it's easier to find thing I need). Back to the values.xml 8 usages were found for the @color/abc_secondary_text_material_light. It was a Light theme so 4 left in 2 themes: Base.ThemeOverlay.AppCompat.Light and Platform.AppCompat.Light. The first theme was a child of the second one so there were only 2 attributes with that color resource: android:textColorSecondary and android:textColorTertiaryin the Base.ThemeOverlay.AppCompat.Light. Changing their values directly in the values.xml and running the app I found that the final correct attribute was android:textColorSecondary. Next I needed a theme or another attribute so I could change it in my app's style.xml (because my theme had as the parent the Theme.AppCompat.Light and not the ThemeOverlay.AppCompat.Light). I searched in the same file for the Base.ThemeOverlay.AppCompat.Light. It had a child ThemeOverlay.AppCompat.Light. Searching for the ThemeOverlay.AppCompat.Light I found its usage in the Base.Theme.AppCompat.Light.DarkActionBar theme as the actionBarPopupTheme attribute value. My app's theme Theme.AppCompat.Light.DarkActionBar was a child of the found Base.Theme.AppCompat.Light.DarkActionBar so I could use that attribute in my styles.xml without problems. As it's seen in the example code above I created a child theme from the mentioned ThemeOverlay.AppCompat.Light and changed the android:textColorSecondary attribute.

当菜单项膨胀时，我使用html标记来更改单个项目的文本颜色。希望对大家有所帮助。

public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.menu_main, menu);
    menu.findItem(R.id.main_settings).setTitle(Html.fromHtml("<font color='#ff3824'>Settings</font>"));
    return true;
}

我找到了，尤利卡!!

在你的应用主题中:

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <item name="android:actionBarStyle">@style/ActionBarTheme</item>
    <!-- backward compatibility -->          
    <item name="actionBarStyle">@style/ActionBarTheme</item>        
</style>

这是你的动作栏主题:

<style name="ActionBarTheme" parent="@style/Widget.AppCompat.Light.ActionBar.Solid.Inverse">
   <item name="android:background">@color/actionbar_bg_color</item>
   <item name="popupTheme">@style/ActionBarPopupTheme</item
   <!-- backward compatibility -->
   <item name="background">@color/actionbar_bg_color</item>
</style>

这是你弹出的主题:

 <style name="ActionBarPopupTheme">
    <item name="android:textColor">@color/menu_text_color</item>
    <item name="android:background">@color/menu_bg_color</item>
 </style>

干杯,)

通过使用SpannableString而不是String，您可以轻松地更改菜单项文本的颜色。

@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
    inflater.inflate(R.menu.your_menu, menu);

    int positionOfMenuItem = 0; // or whatever...
    MenuItem item = menu.getItem(positionOfMenuItem);
    SpannableString s = new SpannableString("My red MenuItem");
    s.setSpan(new ForegroundColorSpan(Color.RED), 0, s.length(), 0);
    item.setTitle(s);
}
