Android编译出现DSL element android.dataBinding.enabled is obsolete and has been replaced with android

一、问题

  编译的时候发现，发现以下警告，大概意思是

  DSL元素的android.dataBinding。已被替换为“android.buildFeatures.dataBinding”，它将在5.0版的Android Gradle插件中被删除。

build.gradle: DSL element 'android.dataBinding.enabled' is obsolete and has been replaced with 'android.buildFeatures.dataBinding'.
It will be removed in version 5.0 of the Android Gradle plugin.
Affected Modules: app

二、解决方案

 参考：https : //developer.android.com/studio/preview/features#agp-4-0-0，发现从Android Gradle Plugin4.0.0 开始，有一个被称为buildFeatures启用构建功能的模块，所以要使用新的AGP插件启用数据绑定，得改为以下配置：

buildFeatures{
        dataBinding = true
        // for view binding :
        // viewBinding = true
    }
