java.lang.NoClassDefFoundError: androidx/core/view/ViewCompat when using FlexboxLayout

Question

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

<?xml version="1.0" encoding="utf-8"?>
<com.google.android.flexbox.FlexboxLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent">



</com.google.android.flexbox.FlexboxLayout>

我遇到错误 Error ScreenShot

提前致谢。我们将不胜感激。

Answer 1

解决方案在这里

FlexboxLayout 1.1.0，该库预计与 AndroidX.

一起使用

如果您想使用 1.1.0 and above 而不是迁移到 AndroidX

AndroidX 使用这个

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

对于com.android.support:appcompat

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