这是你如何用颜色给一个特定的菜单项上色，适用于所有API级别:

public static void setToolbarMenuItemTextColor(final Toolbar toolbar,
                                               final @ColorRes int color,
                                               @IdRes final int resId) {
    if (toolbar != null) {
        for (int i = 0; i < toolbar.getChildCount(); i++) {
            final View view = toolbar.getChildAt(i);
            if (view instanceof ActionMenuView) {
                final ActionMenuView actionMenuView = (ActionMenuView) view;
                // view children are accessible only after layout-ing
                actionMenuView.post(new Runnable() {
                    @Override
                    public void run() {
                        for (int j = 0; j < actionMenuView.getChildCount(); j++) {
                            final View innerView = actionMenuView.getChildAt(j);
                            if (innerView instanceof ActionMenuItemView) {
                                final ActionMenuItemView itemView = (ActionMenuItemView) innerView;
                                if (resId == itemView.getId()) {
                                    itemView.setTextColor(ContextCompat.getColor(toolbar.getContext(), color));
                                }
                            }
                        }
                    }
                });
            }
        }
    }
}

通过这样做，你会失去背景选择器的效果，所以下面的代码将一个自定义的背景选择器应用到所有菜单项的子项上。

public static void setToolbarMenuItemsBackgroundSelector(final Context context,
                                                         final Toolbar toolbar) {
    if (toolbar != null) {
        for (int i = 0; i < toolbar.getChildCount(); i++) {
            final View view = toolbar.getChildAt(i);
            if (view instanceof ImageButton) {
                // left toolbar icon (navigation, hamburger, ...)
                UiHelper.setViewBackgroundSelector(context, view);
            } else if (view instanceof ActionMenuView) {
                final ActionMenuView actionMenuView = (ActionMenuView) view;

                // view children are accessible only after layout-ing
                actionMenuView.post(new Runnable() {
                    @Override
                    public void run() {
                        for (int j = 0; j < actionMenuView.getChildCount(); j++) {
                            final View innerView = actionMenuView.getChildAt(j);
                            if (innerView instanceof ActionMenuItemView) {
                                // text item views
                                final ActionMenuItemView itemView = (ActionMenuItemView) innerView;
                                UiHelper.setViewBackgroundSelector(context, itemView);

                                // icon item views
                                for (int k = 0; k < itemView.getCompoundDrawables().length; k++) {
                                    if (itemView.getCompoundDrawables()[k] != null) {
                                        UiHelper.setViewBackgroundSelector(context, itemView);
                                    }
                                }
                            }
                        }
                    }
                });
            }
        }
    }
}

下面是helper函数:

public static void setViewBackgroundSelector(@NonNull Context context, @NonNull View itemView) {
    int[] attrs = new int[]{R.attr.selectableItemBackgroundBorderless};
    TypedArray ta = context.obtainStyledAttributes(attrs);
    Drawable drawable = ta.getDrawable(0);
    ta.recycle();

    ViewCompat.setBackground(itemView, drawable);
}

最简单的方法为单个工具栏定制菜单颜色，而不是为AppTheme

    <android.support.design.widget.AppBarLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:theme="@style/AppTheme.AppBarOverlay.MenuBlue">
        <android.support.v7.widget.Toolbar
            android:id="@+id/toolbar"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"/>
    </android.support.design.widget.AppBarLayout>

xml上常用的工具栏

<style name="AppTheme.AppBarOverlay" parent="ThemeOverlay.AppCompat.Dark.ActionBar"/>

自定义工具栏样式

<style name="AppTheme.AppBarOverlay.MenuBlue">
    <item name="actionMenuTextColor">@color/blue</item>
</style>

主题中的一句话:)

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

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！

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。

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;
}
