1-在build下面添加dataBinding功能:

android {
...
buildFeatures {
        dataBinding true
    }
...
}

2-将匕首版本改为2.31.2

annotationProcessor "com.google.dagger:dagger-compiler:$daggerVersion"
implementation "com.google.dagger:dagger:$daggerVersion"

3- butterKnife版本也更改为10.2.3

implementation 'com.jakewharton:butterknife:10.2.3'
annotationProcessor 'com.jakewharton:butterknife-compiler:10.2.3'

把这段代码放在Gradle Scripts >> build中。gradle(模块:appName.app)

在buildTypes之后，包括数据投标代码

buildTypes {
       release {
           .......
          ........
       }
   }
 //here is the code...
   buildFeatures {
       dataBinding = true
   } 

这就是全部:)

把它放到构建中。gradle(应用程序级别)。它将适用于大于或等于4.0.0的android studio版本。

android {
    buildFeatures{ 
        dataBinding true // for data binding 
        viewBinding true // for view binding
    }
}

从Android Gradle Plugin 4.0.0-alpha05开始，有一个名为buildFeatures的新块来启用构建功能。

因此，为了使数据绑定与新的AGP插件，你必须在模块(例如:app)级别的gradle文件

构建。gradle (Groovy DSL)

// shorter version
// android.buildFeatures.dataBinding true


// longer version

android {

    buildFeatures {

         dataBinding true

         // for view binding:
         // viewBinding true
    }
}

build.gradle.kts （ Kotlin DSL ）

// shorter version
// android.buildFeatures.dataBinding = true


// longer version

android {

  buildFeatures {

         dataBinding = true

         // for view binding:
         // viewBinding = true
    }
}

annotationProcessor 'com.jakewharton:butterknife-compiler:10.2.3'

以下工作:

android { compileSdkVersion 30 buildToolsVersion“30.0.3”

defaultConfig {
    applicationId "com.poet.navviewmodeljave"
    minSdkVersion 19
    targetSdkVersion 30
    versionCode 1
    versionName "1.0"
    //dataBinding.enabled true
    buildFeatures.dataBinding
    testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
}
