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,)

多亏了麦克斯。mussterman，这是我在第22关的解决方案:

public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.menu_main, menu);
    SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
    MenuItem searchMenuItem = menu.findItem(R.id.search);
    SearchView searchView = (SearchView) searchMenuItem.getActionView();
    searchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()));
    searchView.setSubmitButtonEnabled(true);
    searchView.setOnQueryTextListener(this);
    setMenuTextColor(menu, R.id.displaySummary, R.string.show_summary);
    setMenuTextColor(menu, R.id.about, R.string.text_about);
    setMenuTextColor(menu, R.id.importExport, R.string.import_export);
    setMenuTextColor(menu, R.id.preferences, R.string.settings);
    return true;
}

private void setMenuTextColor(Menu menu, int menuResource, int menuTextResource) {
    MenuItem item = menu.findItem(menuResource);
    SpannableString s = new SpannableString(getString(menuTextResource));
    s.setSpan(new ForegroundColorSpan(Color.BLACK), 0, s.length(), 0);
    item.setTitle(s);
}

硬编码的颜色。BLACK可以成为setMenuTextColor方法的附加参数。此外，我只使用这个菜单项是android:showAsAction="never"。

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);
}

简短的回答是肯定的。幸运的你! 要做到这一点，你需要覆盖Android默认样式的一些样式:

首先，看看Android中主题的定义:

<style name="Theme.IconMenu">
<!-- Menu/item attributes -->
<item name="android:itemTextAppearance">@android:style/TextAppearance.Widget.IconMenu.Item</item>
<item name="android:itemBackground">@android:drawable/menu_selector</item>
<item name="android:itemIconDisabledAlpha">?android:attr/disabledAlpha</item>
<item name="android:horizontalDivider">@android:drawable/divider_horizontal_bright</item>
<item name="android:verticalDivider">@android:drawable/divider_vertical_bright</item>
<item name="android:windowAnimationStyle">@android:style/Animation.OptionsPanel</item>
<item name="android:moreIcon">@android:drawable/ic_menu_more</item>
<item name="android:background">@null</item>
</style>

因此，菜单中文本的外观在@android:style/ textappearance . widget。iconmenu . item中 现在，在样式的定义中:

<style name="TextAppearance.Widget.IconMenu.Item" parent="TextAppearance.Small">
<item name="android:textColor">?textColorPrimaryInverse</item>
</style>

现在我们有了问题中的颜色名称，如果你查看系统资源的颜色文件夹:

<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_enabled="false" android:color="@android:color/bright_foreground_light_disabled" /> 
<item android:state_window_focused="false" android:color="@android:color/bright_foreground_light" /> 
<item android:state_pressed="true" android:color="@android:color/bright_foreground_light" /> 
<item android:state_selected="true" android:color="@android:color/bright_foreground_light" /> 
<item android:color="@android:color/bright_foreground_light" /> 
<!--  not selected --> 
</selector>

最后，以下是你需要做的事情:

TextAppearance.Widget.IconMenu覆盖”。项目”，创造自己的风格。然后将它链接到您自己的选择器，使其成为您想要的方式。 希望这对你有所帮助。 好运！

试试这段代码....

 @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);
    }

您可以通过编程方式设置颜色。

private static void setMenuTextColor(final Context context, final Toolbar toolbar, final int menuResId, final int colorRes) {
    toolbar.post(new Runnable() {
        @Override
        public void run() {
            View settingsMenuItem =  toolbar.findViewById(menuResId);
            if (settingsMenuItem instanceof TextView) {
                if (DEBUG) {
                    Log.i(TAG, "setMenuTextColor textview");
                }
                TextView tv = (TextView) settingsMenuItem;
                tv.setTextColor(ContextCompat.getColor(context, colorRes));
            } else { // you can ignore this branch, because usually there is not the situation
                Menu menu = toolbar.getMenu();
                MenuItem item = menu.findItem(menuResId);
                SpannableString s = new SpannableString(item.getTitle());
                s.setSpan(new ForegroundColorSpan(ContextCompat.getColor(context, colorRes)), 0, s.length(), 0);
                item.setTitle(s);
            }

        }
    });
}
