Xamarin.Forms 中 TabbedPage 上的 Android.Views.InflateException

Question

错误： Android.Views.InflateException: 'Binary XML file line #1: Binary XML file line #1: Error inflating class android.support.design.widget.TabLayout'

我添加了新的 TabbedPage，然后在 AppShell.xaml

<ShellContent Title="About" Route="AboutTabbedPage" ContentTemplate="{DataTemplate local:AboutTabbedPage}"  />

但是当我在模拟器中点击“关于”时，它抛出错误：

Android.Views.InflateException: 'Binary XML file line #1: Binary XML file line #1: Error inflating class android.support.design.widget.TabLayout'

在任何新的 TabbedPage 上都会引发错误。

TabbedPage的内容如下

<?xml version="1.0" encoding="utf-8" ?>
<TabbedPage xmlns="http://xamarin.com/schemas/2014/forms"
            xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
            x:Class="myapp.Views.AboutTabbedPage"
            Title="{Binding Title}"
             xmlns:vm="clr-namespace:myapp.ViewModels"
            
            >
  <!--Pages can be added as references or inline-->

    <ContentPage Title="Tab 2">
        <StackLayout>
            <Label Text="Green"  HorizontalTextAlignment="Center" HorizontalOptions="FillAndExpand" Margin="5" />
            <BoxView Color="Green" VerticalOptions="FillAndExpand" />
        </StackLayout>
    </ContentPage>
</TabbedPage>

android项目中的styles.xml如下：

 <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>
  </style>

Answer 1

我不得不更改 ...Android\Resources\layout\Tabber.xml 项目中的 TabLayout 从 android.support.design.widget.TabLayout 到 com.google.android.material.tabs.TabLayout 然后它开始按预期工作。
