看来

  <item name="android:itemTextAppearance">@style/myCustomMenuTextAppearance</item>

在我的主题中

   <style name="myCustomMenuTextAppearance" parent="@android:style/TextAppearance.Widget.IconMenu.Item">
        <item name="android:textColor">@android:color/primary_text_dark</item>
    </style>

在styles.xml中，更改列表项的样式，但不更改菜单项的样式。

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);
}

Options menu in android can be customized to set the background or change the text appearance. The background and text color in the menu couldn’t be changed using themes and styles. The android source code (data\res\layout\icon_menu_item_layout.xml)uses a custom item of class “com.android.internal.view.menu.IconMenuItem”View for the menu layout. We can make changes in the above class to customize the menu. To achieve the same, use LayoutInflater factory class and set the background and text color for the view.

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.my_menu, menu);
    getLayoutInflater().setFactory(new Factory() {
        @Override
        public View onCreateView(String name, Context context, AttributeSet attrs) {
            if (name .equalsIgnoreCase(“com.android.internal.view.menu.IconMenuItemView”)) {
                try{
                    LayoutInflater f = getLayoutInflater();
                    final View view = f.createView(name, null, attrs);
                    new Handler().post(new Runnable() {
                        public void run() {
                            // set the background drawable
                            view .setBackgroundResource(R.drawable.my_ac_menu_background);

                            // set the text color
                            ((TextView) view).setTextColor(Color.WHITE);
                        }
                    });
                    return view;
                } catch (InflateException e) {
                    } catch (ClassNotFoundException e) {}
            }
            return null;
        }
    });
    return super.onCreateOptionsMenu(menu);
}

添加textColor如下所示

<style name="MyTheme.PopupOverlay" parent="ThemeOverlay.AppCompat.Light">
    <item name="android:textColor">@color/radio_color_gray</item>
</style>

并在xml文件中的工具栏中使用它

<androidx.appcompat.widget.Toolbar
     android:id="@+id/toolbar"
     android:layout_width="match_parent"
     android:layout_height="?attr/actionBarSize"
     app:popupTheme="@style/MyTheme.PopupOverlay" /> 

只要去 值-样式和内部样式和类型 你的颜色

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
