java - 只能与 Theme.AppCompat 主题（或后代）一起使用的 AppCompat 小部件

问题描述

iOS 开发者在这里被丢给了一个 Android 项目的狼群。ThemeUtils: View class androidx.appcompat.widget.AppCompatTextView is an AppCompat widget that can only be used with a Theme.AppCompat theme (or descendant).只要运行以下代码片段，我就会收到一些错误代码，它们都会说类似的内容：

view = inflater.inflate(R.layout.f_basic_dashboard_screen, null, false)

我的充气机实例化如下：

val inflater: LayoutInflater = LayoutInflater.from(SqueaksApplication.getApplicationInstance())

SqueaksApplication.getApplicationInstance()只返回一个实例public class SqueaksApplication extends Application

我对这个问题找到的几乎每个答案都指向项目的清单作为问题并且需要为项目提供一个主题。我的项目清单如下所示：

<application
  android:name=".SqueaksApplication"
  android:allowBackup="false"
  android:icon="@mipmap/ic_launcher"
  android:label="@string/app_name"
  android:supportsRtl="true"
  android:theme="@style/AppTheme"
  android:usesCleartextTraffic="true"
  tools:ignore="GoogleAppIndexingWarning,UnusedAttribute"
  tools:replace="android:icon,android:allowBackup">

如您所见，我的清单已经包含该行android:theme="@style/AppTheme"

我的项目在许多不同的地方都使用了布局充气机，但这是我遇到的唯一一个抛出错误的地方。非常感谢您的任何见解或解决方案，谢谢！

编辑：根据要求，这是我的styles.xml：

解决方案

您的问题是context使用的：val inflater: LayoutInflater = LayoutInflater.from(SqueaksApplication.getApplicationInstance()).

ApplicationContext 没有您的应用主题。
您需要传递Activity，而不是应用程序上下文。
