Question

尝试使用kotlin在项目中使用新的Android数据绑定（https://developer.android.com/tools/data-binding/guide.html），但在处理布局资源时失败：

我已经用Kotlin here

重新写了Blog for Data Binding android

使用Classpath

classpath 'com.android.tools.build:gradle:3.0.0-beta2'

<强>依赖

apply plugin: 'kotlin-android'

apply plugin: 'kotlin-android-extensions'

apply plugin: 'kotlin-kapt'

android {
    ...
    dataBinding {
        enabled = true
    }
}

dependencies {
    ......
    kapt 'com.android.databinding:compiler:2.3.1'
}
