我刚刚通过Android Studio菜单选项迁移到androidx __CODE__
我收到以下错误:
android.view.InflateException:二进制XML文件行#2:二进制XML文件行#2:错误膨胀类androidx.constraintlayout.ConstraintLayout
任何的想法？

我通过改变所有出现的问题来解决我的问题
androidx.constraintlayout.ConstraintLayout
至
androidx.constraintlayout.widget.ConstraintLayout
Mar*_*ler 39
添加androidx.constraintlayout.ConstraintLayout到依赖项:
dependencies {
// https://mvnrepository.com/artifact/androidx.constraintlayout/constraintlayout
implementation "androidx.constraintlayout:constraintlayout:1.1.3"
}
存储库是mavenCentral().
之后我有同样的问题：
我也用：
implementation "uk.co.chrisjenx:calligraphy:2.3.0"
我尝试了这个问题的所有帖子，但没有成功。
我通过向.disableCustomViewInflation()Calligraphy init添加一个字符串来修复它：
@Override
public void onCreate() {
super.onCreate();
// ...
CalligraphyConfig.initDefault(new CalligraphyConfig.Builder()
.setDefaultFontPath("fonts/Sans-Regular.ttf")
.setFontAttrId(R.attr.fontPath)
.disableCustomViewInflation() // <----- this fix
.build());
// ...
}
我希望书法的下一个版本（克里斯托弗·詹金斯感谢你的出色工作）也能在里面修复它。
我遇到了同样的问题，我如下解决了它：
在您的依赖中，如果您添加了
implementation 'androidx.constraintlayout:constraintlayout:1.x.x' 那是正确的
但是在xml布局文件中，您必须将小部件用作
androidx.constraintlayout.widget.ConstraintLayout
如果将mavenCentral（）作为Gradle文件中的存储库添加并更改androidx.constraintlayout.ConstraintLayout为androidx.constraintlayout.widget.ConstraintLayout不能解决问题后，请尝试执行Invalidate cache并从文件菜单重新启动。它为我工作。

build.gradle =>检查依赖版本
implementation 'androidx.constraintlayout:constraintlayout:1.1.1'
改变
implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
解决了问题
确保您的项目完全迁移到 androidx，就我而言，我发现：
<android.support.constraint.ConstraintLayout
代替
<androidx.constraintlayout.widget.ConstraintLayout
所以改变它，我的问题就解决了！
