迁移到androidx后膨胀类androidx.constraintlayout.ConstraintLayout时出错
迁移到androidx后膨胀类androidx.constraintlayout.ConstraintLayout时出错
提问于 2018-10-19 05:07:42
我刚刚通过Android Studio菜单选项Refactor -> Refactor to AndroidX迁移到androidx
我得到以下错误：
android.view.InflateException:二进制XML文件第2行:二进制XML文件第2行:膨胀类androidx.constraintlayout.ConstraintLayout时出错
有什么想法吗？

我通过更改所有出现的
androidx.constraintlayout.ConstraintLayout
至
androidx.constraintlayout.widget.ConstraintLayout

将androidx.constraintlayout.widget.ConstraintLayout添加到依赖项中：
dependencies {
// https://mvnrepository.com/artifact/androidx.constraintlayout/constraintlayout
implementation "androidx.constraintlayout:constraintlayout:1.1.3"
}它可以在mavenCentral()上找到。

我也遇到了同样的问题，我的解决方法如下：
如果您添加了
正确的implementation 'androidx.constraintlayout:constraintlayout:1.x.x'
但在xml布局文件中，您必须将小部件用作
androidx.constraintlayout.widget.ConstraintLayout
