android - 迁移到 androidx 后膨胀类 android.support.design.widget.CoordinatorLayout 时出错

Question

我刚刚迁移到 Androidx，但迁移后出现以下错误:

Caused by: android.view.InflateException: Binary XML file line #12: Binary XML file line #2: Error inflating class android.support.design.widget.CoordinatorLayout`

有什么想法吗？

堆栈跟踪:

        compileSdkVersion 28
        minSdkVersion 18
        targetSdkVersion 28


dependencies {
    implementation 'com.android.support:appcompat-v7:28.0.0'
    implementation 'com.android.support:design:28.0.0'
    implementation 'com.android.support.constraint:constraint-layout:1.1.3'
} ```

Answer 1

迁移到 Androidx 后，我有类似的经历。我按照以下步骤解决了问题:[1]确保布局文件使用这个

 <androidx.coordinatorlayout.widget.CoordinatorLayout>

 </androidx.coordinatorlayout.widget.CoordinatorLayout>

[2]如果 Android Studio 在迁移到 Androidx 后未更改支持库导入，请执行此步骤。

转到类文件(java 或 kt)，删除与以前的库相关的所有导入，并允许 Android Studio 导入适当的 Androidx 库。对所有其他迁移问题执行这些操作。

这是你的依赖项应该是这样的:

implementation 'androidx.appcompat:appcompat:1.1.0'
implementation 'androidx.drawerlayout:drawerlayout:1.0.0' //DrawerLayout
implementation 'androidx.coordinatorlayout:coordinatorlayout:1.0.0'
implementation 'com.google.android.material:material:1.0.0' //androidx AppBarLayout, CollapsingToolbarLayout etc.
implementation 'androidx.webkit:webkit:1.0.0' //androidx webview
