Android studio 呈现问题：找不到以下类

我想在Android设计支持库中使用工具栏动画。我使用了以下信息：我配置了我的activity.xml文件。但我犯了这些错误：

找不到以下类： -android.support.design.widget.AppBarLayout（修复构建路径、编辑XML、创建类）

-android.support.design.widget.collazingToolbarLayout（修复构建路径、编辑XML、创建类）

-android.support.design.widget.CoordinatorLayout（修复构建路径、编辑XML、创建类）

-android.support.v7.widget.Toolbar（修复构建路径、编辑XML、创建类）

这是Logcat日志：

改变

android.support.design.widget.CoordinatorLayout
android.support.design.widget.AppBarLayout
android.support.design.widget.CollapsingToolbarLayout
android.support.v7.widget.Toolbar

到

并添加到gradle中的依赖项

implementation 'com.android.support:appcompat-v7:28.0.0'
implementation 'com.android.support:design:28.0.0'

---

或者使用keep simple support library的所有AndroidX依赖项。使用此链接跟踪依赖项，反之亦然@akiilhan，在我重新运行我的旧项目后，前一天刚刚遇到同样的问题：）Upvote answer and add to tread name“Error inflating class”将对其他用户有帮助。它还帮助了我：实现'com.google.android.material:material:1.1.0'

android.support.design.widget.CoordinatorLayout
android.support.design.widget.AppBarLayout
android.support.design.widget.CollapsingToolbarLayout
android.support.v7.widget.Toolbar

androidx.coordinatorlayout.widget.CoordinatorLayout
com.google.android.material.appbar.AppBarLayout
com.google.android.material.appbar.CollapsingToolbarLayout
androidx.appcompat.widget.Toolbar

implementation 'com.android.support:appcompat-v7:28.0.0'
implementation 'com.android.support:design:28.0.0'
