android-检索项目的父项时出错：找不到与给定名称’Theme.AppCompat.Light.DarkActionBar’匹配的资源. Xamarin视觉工作室

好吧,它给了我9条style.xml错误,内容是

Error retrieving parent for item: No resource found that matches the
given name ‘Theme.AppCompat.Light.DarkActionBar’ Error No resource
found that matches the given name: attr ‘windowNoTitle’.

就像我在xamarin中使用Visual Studio

    <?xml version="1.0" encoding="utf-8" ?>
<resources>

  <style name="Theme.Splash" parent="android:Theme">
    <item name="android:windowBackground">@drawable/splashscreen</item>
    <item name="android:windowNoTitle">true</item>
    <item name="android:windowActionBar">false</item>
  </style>

  <style name="MainTheme" parent="MainTheme.Base">
  </style>
  <!-- Base theme applied no matter what API -->
  <style name="MainTheme.Base" parent="Theme.AppCompat.Light.DarkActionBar">
    <!--If you are using revision 22.1 please use just windowNoTitle. Without android:-->
    <item name="windowNoTitle">true</item>
    <!--We will be using the toolbar so no need to show ActionBar-->
    <item name="windowActionBar">false</item>
    <!-- Set theme colors from http://www.google.com/design/spec/style/color.html#color-color-palette -->
    <!-- colorPrimary is used for the default action bar background -->
    <item name="colorPrimary">#a84849</item>
    <!-- colorPrimaryDark is used for the status bar -->
    <item name="colorPrimaryDark">#444</item>
    <!-- colorAccent is used as the default value for colorControlActivated
         which is used to tint widgets -->
    <item name="colorAccent">#a84849</item>
    <!-- You can also set colorControlNormal, colorControlActivated
         colorControlHighlight and colorSwitchThumbNormal. -->
    <item name="windowActionModeOverlay">true</item>

    <!--<item name="datePickerDialogTheme">@style/AppCompatDialogStyle</item>-->
  </style>

  <style name="AppCompatDialogStyle" parent="Theme.AppCompat.Light.Dialog">
    <item name="colorAccent">#A84849</item>
  </style>
</resources>

解决方法:

您可能未引用android支持v7 AppCompat库.它将显示如下错误.

请添加支持v7 AppCompat库的表格nuget：

您将建立成功：
