Android Kotlin双向数据绑定BR类错误

问题描述 投票:0回答:1

我正在尝试使用kotlin和两种方式进行数据绑定以在文本视图上显示基本的android应用程序,以查看编辑文本中的更改。但我收到此错误:w:[kapt]请求了增量注释处理,但由于以下处理器不是增量处理器,因此禁用了支持:android.databinding.annotationprocessor.ProcessDataBinding(DYNAMIC)。

当我尝试使用一种方法进行数据绑定时,它运行良好,它向我显示了Contact类的名称字段成功

我的代码:build.gradle(Project)

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
            ext.kotlin_version = '1.3.61'
            repositories {
                google()
                jcenter()

    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.5.3'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        google()
        jcenter()

    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

build.gradle(module:app)

apply plugin: 'com.android.application'

apply plugin: 'kotlin-android'
apply plugin: 'kotlin-kapt'

android {
    compileSdkVersion 29
    dataBinding{
        enabled = true
    }
    buildToolsVersion "29.0.2"
    defaultConfig {
        applicationId "com.mvvm.demo"
        minSdkVersion 16
        targetSdkVersion 29
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }
    buildTypes {

            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {

        @Bindable
        var _name: String = Name
            set(value) {
                field = value

很遗憾,此错误尚未解决。我希望该警告将在下一次更新中得到解决。由于此警告,我自11月以来一直在等待更新]
