如何在模塊（Android Studio）中使用com.android.databinding？

我想用com.android.databinding: dataBinder創建一個庫。如何在模塊（Android Studio）中使用com.android.databinding？

build.gradle for project:

buildscript { 
    repositories { 
     jcenter() 
    } 
    dependencies { 
     classpath 'com.android.tools.build:gradle:1.5.0' 
     classpath 'com.android.databinding:dataBinder:1.0-rc4' 


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

allprojects { 
    repositories { 
     jcenter() 
     maven { url "https://jitpack.io" } 
     //gradlew -Dhttps.proxyHost=127.0.0.1 -Dhttps.proxyPort=8580 
    } 
} 


task clean(type: Delete) { 
    delete rootProject.buildDir 
}

build.gradle for module :

apply plugin: 'com.android.library' // apply plugin: 'com.android.application' 
apply plugin: 'com.android.databinding' 


android { 
    compileSdkVersion 23 
    buildToolsVersion "23.0.2" 
    aaptOptions { 
     additionalParameters "--no-version-vectors" 
    } 

    defaultConfig { 
     minSdkVersion 10 
     targetSdkVersion 23 
     versionCode 1 
     versionName "1.1" 
     multiDexEnabled true 
     generatedDensities = [] 
    } 
    buildTypes { 
     release { 
      minifyEnabled false 
      proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' 
     } 
    } 

} 


dependencies { 
    compile fileTree(dir: 'libs', include: ['*.jar']) 
    testCompile 'junit:junit:4.12' 
    compile 'com.android.support:appcompat-v7:23.2.0' 
    compile 'com.jakewharton:butterknife:7.0.1' 
    compile 'com.android.support:support-v4:23.2.0' 
}

更改 apply plugin: 'com.android.application'到apply plugin: 'com.android.library'。但當我改變了代碼以下時發生錯誤。

錯誤的：

按照這裏的指南：

http://developer.android.com/tools/data-binding/guide.html

您必須添加dataBinding.enabled = true到android部分。你也應該使用android gradle插件1.5.0或更高版本。

您再也不需要apply plugin: 'com.android.databinding'了。數據綁定現在包含在Android gradle插件中。

我刪除了應用插件：'com.android.databinding'發生了這個errpr。錯誤：無法找到方法'android.databinding.tool.LayoutXmlProcessor。（Ljava/lang/String; Landroid/databinding/tool/writer/JavaFileWriter; IZLandroid/databinding/tool/LayoutXmlProcessor $ OriginalFileLookup;） –

您正在使用哪個版本的Android gradle插件？ –

另外，你的依賴關係是否有jcenter？ –

只有當你正在使用的gradle產出2.0或更高版本添加

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

。例如：：

classpath 'com.android.tools.build:gradle:2.3.0'
