java.lang.NoClassDefFoundError：使用FlexboxLayout时的androidx/core/view/ViewCompat

我正在使用FlexboxLayout

在FlexboxLayout的build.gradle中添加了以下依赖项

dependencies {
implementation 'com.google.android:flexbox:1.1.0'
}


myLayout


xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_
android:layout_>



我收到错误Error ScreenShot以下

我该如何解决这个问题

提前致谢.您的努力将不胜感激.

解决方法:

解决方案在这里

FlexboxLayout 1.1.0,该库预计将与AndroidX.一起使用

如果要使用1.1.0及更高版本而不是迁移到AndroidX

对于AndroidX使用此

dependencies {
implementation 'com.google.android:flexbox:1.1.0'
}


对于com.android.support:appcompat

dependencies {
implementation 'com.google.android:flexbox:1.0.0'
}


有关更多信息,请查看FlexboxLayout
希望这能帮到别人
