更改菜单项颜色

Question

我正在尝试更改菜单项的颜色，但没有成功。

我想根据我在颜色文件中定义的 material 颜色系统更改菜单项的颜色。

这是我的 xml 文件。有什么想法吗？

app_bar_navigationdrawer.xml

    <com.google.android.material.appbar.AppBarLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:theme="@style/AppTheme.AppBarOverlay">

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

    </com.google.android.material.appbar.AppBarLayout>

    <include layout="@layout/content_navigation_drawer" />

    <com.google.android.material.floatingactionbutton.FloatingActionButton
        android:id="@+id/fab"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="bottom|end"
        android:layout_margin="@dimen/fab_margin"
        app:srcCompat="@drawable/ic_baseline_add_circle_outline_24" />

</androidx.coordinatorlayout.widget.CoordinatorLayout>

colors.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <color name="colorPrimary">#ff0125</color>  <!-- 6200EE -->

颜色-night.xml

正如您在附件中看到的，菜单项的颜色在深色主题下也不会因光线而改变。

您可以覆盖工具栏菜单中使用的颜色。

  <com.google.android.material.appbar.MaterialToolbar
        style="@style/Widget.MaterialComponents.Toolbar.Primary"
        app:popupTheme="@style/AppTheme.PopupOverlay"
        />

与：

<style name="AppTheme.ToolabePopupOverlay" parent="ThemeOverlay.MaterialComponents.Toolbar.Primary">
    <item name="colorSurface">@color/...</item>  <!-- background -->
    <item name="android:textColor">@color/...</item>   <!-- text color -->
</style>

它也适用于 androidx.appcompat.widget.Toolbar。
