推荐答案

解决方案是，我需要更新程序包，只有Xamarin.Forms程序包.如下图所示.

The solution is, I needed to update the package, only the Xamarin.Forms package. Like the below image.

更新后，packages.config文件应如下所示

After update, the packages.config file should be like below

<?xml version="1.0" encoding="utf-8"?>
<packages>
  <package id="Xamarin.Android.Support.Animated.Vector.Drawable" version="23.3.0" targetFramework="monoandroid60" />
  <package id="Xamarin.Android.Support.Design" version="23.3.0" targetFramework="monoandroid60" />
  <package id="Xamarin.Android.Support.v4" version="23.3.0" targetFramework="monoandroid60" />
  <package id="Xamarin.Android.Support.v7.AppCompat" version="23.3.0" targetFramework="monoandroid60" />
  <package id="Xamarin.Android.Support.v7.CardView" version="23.3.0" targetFramework="monoandroid60" />
  <package id="Xamarin.Android.Support.v7.MediaRouter" version="23.3.0" targetFramework="monoandroid60" />
  <package id="Xamarin.Android.Support.v7.RecyclerView" version="23.3.0" targetFramework="monoandroid60" />
  <package id="Xamarin.Android.Support.Vector.Drawable" version="23.3.0" targetFramework="monoandroid60" />
  <package id="Xamarin.Forms" version="2.3.2.127" targetFramework="monoandroid60" />
</packages>

并忽略其余的软件包，如下所示.

And ignore the rest of the packages like below.
