如何在添加新的 Activity 的同时在旧的 android 项目中添加数据绑定？

Question

通过 Android studio 添加 activity 时出现数据绑定错误。如何解决这个错误？

我正在尝试通过 android studio 在现有项目中添加新的 Activity。那一次我用的是targetSdkVersion 30 sdk。但是在更新 targetSdkVersion 32 之后，尝试通过 android studio 添加新的 Activity 时，出现如图所示的错误。

这是我的build.gradle


plugins {
    id 'com.android.application'
    id 'com.google.gms.google-services'
    id 'com.google.firebase.crashlytics'
}
apply plugin: 'kotlin-android'

android {
    compileSdkVersion 32
    buildToolsVersion "30.0.3"

    defaultConfig {
        applicationId "com.softwares.bannari.whatstouch"
        minSdkVersion 21
        targetSdkVersion 32
        versionCode 47
        versionName "1.1.47"

        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }

    buildTypes {
        release {
            debuggable false
            minifyEnabled true
            shrinkResources false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'


        }
    }
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }

    bundle {
        language {
            enableSplit = false
        }
    }
    buildFeatures {
        viewBinding true
    }

}

首先删除ActivityGroupsActivityBinding的第一行（导入库），不要删除Binding class及其对象。然后单击 ActivityGroupsActivityBinding class 名称然后您将从左侧获得导入建议。或者您可以通过单击它然后按 alt+enter

再次导入
