Android数据绑定build.gradle同步问题？

Question

用于数据绑定

1)我已经补充说

android {
    dataBinding {
        enabled = true
    }

到我的项目build.gradle,但发生此错误:

Error:(5, 0) Gradle DSL method not found: 'dataBinding()'
Possible causes:

.The project 'exampleDatabinding' may be using a version of Gradle that does    
not contain the method.
Gradle settings

.The build file may be missing a Gradle plugin.

Apply Gradle plugin

2)然后我补充说:

apply plugin: "com.android.databinding"(项目build.gradle)

和classpath "com.android.databinding:dataBinder:1.0-rc1" (项目build.gradle)

但是同样的错误发生了.

Answer 1

在项目的build.gradle文件中添加依赖项

dependencies {
        classpath 'com.android.tools.build:gradle:1.5.0-beta2'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }

并且在模块的build.gradle文件中包含dataBinding部分:

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

build.gradle的版本可以在这里找到:版本
