使用Android Studio 3.0 Canary 3进行数据绑定

Question

我试图在我现有的项目中使用DataBinding.根据文档,我在app模块的build.gradle中添加了以下行,并编译了项目.

 dataBinding {
    enabled = true
}

我收到以下错误:

Could not resolve all dependencies for configuration ':app:devDebugCompileClasspath'.

将这些行添加到模块级build.gradle作为依赖项; Android Studio 3.0改变了它之前通过SDK管理器下载的库的方式 - https://developer.android.com/studio/build/dependencies.html#google-maven

implementation 'com.android.databinding:library:1.3.1'
implementation 'com.android.databinding:adapters:1.3.1'

您可能不需要第二行,具体取决于您使用数据绑定的方式.

而不是implementation,你也可以使用旧的compile.使用implementation将避免建立警告; 它是Android Gradle插件默认使用的新Gradle Java库插件的一部分.

build.gradle如果你还没有,你还需要添加类似下面的内容(通常在你的模块级别) - 这为Android依赖项添加了Google新的Maven存储库:

repositories {
    maven {
        url 'https://maven.google.com'
    }
}
