Android数据绑定构建错误：[数据绑定插件]：无法设置数据绑定。

androidandroid-databinding
12

我正在尝试使用谷歌的Android Data Binding库，曾经一度让它正常工作。现在似乎有“某些”更改正在导致Data Binding库出现问题。我被一个非常通用的错误困扰着，即 [data binding plugin]: failed to setup data binding。

据我所知，当Data Binding库出现问题（比如绑定中的拼写错误）时，会抛出这个错误。问题是，如何找出具体是哪个布局文件导致了问题？有没有人有任何寻找问题所在的提示/建议？除了逐个注释XML布局代码和Java代码文件外，我对如何有效地排除此类问题感到困惑。

Gradle控制台中唯一的线索是这个不太描述性的堆栈跟踪：

有关编程的内容，翻译成中文：同样的问题。有更新吗？ - Alex.Li

没有，我还没有收到任何反馈。我开始回避 Android 数据绑定（至少在它还是 beta 版时）。它似乎缺乏稳健性。 - Tom Opgenorth
我遇到了这个问题，并找到了这个答案。它为我解决了这个问题。 - Lázaro Menezes

随着新的Gradle 2.0.0和Android Studio 2.0的推出，我只需要更改应用程序的gradle文件，添加以下内容 -

android {
    ...

    dataBinding{
        enabled = true
    }
}

它的运作效果非常好。 在项目的Gradle文件中，不需要添加classpath 'com.android.databinding:dataBinder:1.+'，也不需要在应用的Gradle文件中添加apply plugin: 'com.android.databinding'。

数据绑定不再是beta版了，所以请移除

apply plugin: 'com.android.databinding'

来自 build.gradle。

我们不需要添加

classpath 'com.android.databinding:dataBinder:1.+'

无论哪个

apply plugin: 'com.android.databinding'

仅添加

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

如果您正在使用Gradle 2.0或更高版本。 例如：
classpath 'com.android.tools.build:gradle:2.3.0'

我基本上同意@NeoTran的答案，即我们不需要添加以下内容： classpath 'com.android.databinding:dataBinder:1.+' 也不需要 apply plugin: 'com.android.databinding' 但我们需要：
android {
    ...
    dataBinding {
        enabled = true
    }
}

OR for NDK 

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

如果您使用的是Gradle 2.0或更高版本。
在全局build.gradle中，您需要添加例如以下内容：
classpath 'com.android.tools.build:gradle:2.3.3'
classpath 'com.android.tools.build:gradle-experimental:0.9.3' // <-- for NDK

你使用的是哪个版本的Gradle？我记得有些版本存在bug。尝试使用com.android.tools.build:gradle:1.5.0-beta1。
还有，别忘了……
android {
    dataBinding {
        enabled = true
    }

在你的 Gradle 脚本中加入这段代码，这样问题就解决了。

我正在使用gradle 1.5.0（不是beta版本），并且我已经设置了 dataBinding { enabled = true}。回退到1.5.0-beta1会得到相同的结果。 - Tom Opgenorth

我使用2.0.0-alpha3，但仍遇到相同的问题。 - rekire
