感谢您提供的代码示例。 我不得不修改它，让它与上下文菜单一起工作。 这就是我的解。

    static final Class<?>[] constructorSignature = new Class[] {Context.class, AttributeSet.class};

class MenuColorFix implements LayoutInflater.Factory {
    public View onCreateView(String name, Context context, AttributeSet attrs) {
        if (name.equalsIgnoreCase("com.android.internal.view.menu.ListMenuItemView")) {
            try {
                Class<? extends ViewGroup> clazz = context.getClassLoader().loadClass(name).asSubclass(ViewGroup.class);
                Constructor<? extends ViewGroup> constructor = clazz.getConstructor(constructorSignature);
                final ViewGroup view = constructor.newInstance(new Object[]{context,attrs});

                new Handler().post(new Runnable() {
                    public void run() {
                        try {
                            view.setBackgroundColor(Color.BLACK);
                            List<View> children = getAllChildren(view);
                            for(int i = 0; i< children.size(); i++) {
                                View child = children.get(i);
                                if ( child instanceof TextView ) {
                                    ((TextView)child).setTextColor(Color.WHITE);
                                }
                            }
                        }
                        catch (Exception e) {
                            Log.i(TAG, "Caught Exception!",e);
                        }

                    }
                });
                return view;
            }
            catch (Exception e) {
                Log.i(TAG, "Caught Exception!",e);
            }
        }
        return null;
    }       
}

public List<View> getAllChildren(ViewGroup vg) {
    ArrayList<View> result = new ArrayList<View>();
    for ( int i = 0; i < vg.getChildCount(); i++ ) {
        View child = vg.getChildAt(i);
        if ( child instanceof ViewGroup) {
            result.addAll(getAllChildren((ViewGroup)child));
        }
        else {
            result.add(child);
        }
    }
    return result;
}

@Override
public void onCreateContextMenu(ContextMenu menu, View v, ContextMenuInfo menuInfo) {
    LayoutInflater lInflater = getLayoutInflater();
    if ( lInflater.getFactory() == null ) {
        lInflater.setFactory(new MenuColorFix());
    }
    super.onCreateContextMenu(menu, v, menuInfo);
    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.myMenu, menu);
}

对我来说，这适用于Android 1.6、2.03和4.03。

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。

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);
}

将它添加到我的styles.xml中对我有用

<item name="android:textColorPrimary">?android:attr/textColorPrimaryInverse</item>

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


    MenuItem myActionMenuItem = menu.findItem( R.id.action_search);
    SearchView searchView = (SearchView) myActionMenuItem.getActionView();

    EditText searchEditText = (EditText) searchView.findViewById(android.support.v7.appcompat.R.id.search_src_text);
    searchEditText.setTextColor(Color.WHITE); //You color here

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" />
