Java.Lang.IllegalArgumentException .NET MAUI

问题描述 投票:0回答:1

安装 BarcodeScanner.Mobile 版本 8.0.0.1 后,应用程序启动时出现此异常:

MAUI Java.Lang.IllegalArgumentException: 'This component requires that you specify a valid TextAppearance attribute. Update your app theme to inherit from Theme.MaterialComponents (or a descendant).'

有人有同样经历吗?

我不知道我的应用程序的哪一部分需要材质设计,但这就是我修复此崩溃的方法:

  1. 在 Platform/Android/Resources/values 添加 styles.xml 并在里面添加以下代码:
<?xml version="1.0" encoding="utf-8" ?>
<resources>
   <style name="AppTheme" parent="Theme.MaterialComponents.Light.Bridge">
       <!-- Customize your theme here. -->
       <item name="colorPrimary">@color/colorPrimary</item>
       <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
       <item name="colorAccent">@color/colorAccent</item>
   </style>
</resources>
  1. 制作
    styles.xml
    构建动作
    AndroidResource
  2. AndroidManifest.xml
    中的
    <manifest>
    标签中添加了这行代码:
    xmlns:tools="http://schemas.android.com/tools" android:theme="@style/AppTheme" tools:replace="android:theme"
  3. MainActivity.cs
    中替换
    Theme
    属性,如下所示:
    [Activity(Theme = "@style/AppTheme"....)]

所有这些更改都解决了我的问题

Java.Lang.IllegalArgumentException
,但在启动屏幕上再次运行应用程序后再次崩溃,但有例外:


**System.ArgumentException:** 'Cannot bind to the target method because its signature is not compatible with that of the delegate type.'
