android - 无法更改导航栏颜色

Question

我尝试了很多东西来改变导航栏的颜色，比如

Android lollipop change navigation bar color

android change navigation bar color

How to change system navigation bar color

没有效果

我将项目添加到 styles.xml - 使用 Android 8.1

<item name="android:navigationBarColor">@color/theme_color</item>

任何人都知道在 Xamarin.Android 中执行此操作的最佳方法是什么

更新:我在样式文件中尝试了以下代码

  <style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
    <item name="android:windowFullscreen">true</item>
    <item name="android:windowNoTitle">true</item>
    <item name="drawerArrowStyle">@style/DrawerArrowStyle</item>
  </style>

  <style name="DrawerArrowStyle" parent="Theme.AppCompat.Light.NoActionBar">
    <item name="color">@color/red</item>
  </style>

  <style name="AppTheme.NoActionBar">
    <item name="windowActionBar">false</item>
    <item name="windowNoTitle">true</item>
    <item name="android:windowFullscreen">true</item>
    <item name="drawerArrowStyle">@style/DrawerArrowStyle</item>
  </style>

Answer 1

While fixing another issue I had to change and minimum API level to Lollipop and noticed that <itemname="android:navigationBarColor">@color/theme_color</item> started working when minimum API level is set to Lollipop.

所以我认为出于某种原因，Xamarin 需要使用最低 API 版本 Lollipop 才能工作
