Question

尝试将.xml布局绑定到.kt文件时出现此错误。这是我尝试使用Instant App支持功能创建应用程序

这是我的build.gradle（Project：projectname）

    kapt "com.android.databinding:compiler:$versions.android_plugin_version"
}

和Build.Gradle（模块：即时应用）

apply plugin: 'com.android.instantapp'

dependencies {
    implementation project(':feature')
    implementation project(':base')
}

似乎问题是因为在数据绑定自动绑定布局上。

我指的是Android Databinding : package does not exist

和Kapt not generating classes in Instant app feature module

我是否遗漏了build.gradles上的内容？

Answer 1

我找到了解决方法...... 来自https://issuetracker.google.com/issues/63814741

添加

android.enableExperimentalFeatureDatabinding = true
android.databinding.enableV2=true

gradle.properties文件中的

有点解决了这个问题...但我怀疑这是一个解决方案......但是现在......这就是问题的解决方法

Answer 2

我最近也遇到了这个问题。将kapt插件添加到应用程序级别的build.gradle文件解决了我的问题。问题是您的gradle文件中已经具有该插件。也许一段时间后问题就解决了，但是我想离开这个答案，因为这个问题首先出现在Google搜索中。

apply plugin: 'kotlin-kapt'

android studio数据绑定错误未解决的参考：数据绑定
