我为Android库项目启用dataBinding后立即生成错误

我为我的库项目启用dataBinding后,立即收到构建错误：

AAPT：未指定资源类型(在“文本”中,值为“ @ {user.name}”)

如果我为应用程序模块启用了dataBinding,它将正常工作.
但是,如果我为我的lib项目启用dataBinding,则会收到上述错误.

应用程序模块的build.gradle

apply plugin: 'com.android.application'

android {
   compileSdkVersion 23
   buildToolsVersion "23.0.2"

dataBinding{
    enabled true
}
defaultConfig {
    applicationId "xyz.databindingtrial"
    minSdkVersion 19
    targetSdkVersion 23
    versionCode 1
    versionName "1.0"
}
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-v7:23.3.0'
  compile project(path: ':librarytrial')
}

lib项目的build.gradle

apply plugin: 'com.android.library'

android {
  compileSdkVersion 23
  buildToolsVersion "23.0.2"

dataBinding{
    enabled true
}

defaultConfig {
    minSdkVersion 19
    targetSdkVersion 23
    versionCode 1
    versionName "1.0"
}
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-v7:23.3.0'
}

布局文件：

<data class="UserTrackingBinding">

    <variable
        name="user"
        type="xyz.databindingtrial.model.User"/>
</data>

<RelativeLayout
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context="xyz.databindingtrial.MainActivity">

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@{user.name}"/>
</RelativeLayout>

活动代码

@Override
protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  UserTrackingBinding binding = DataBindingUtil.setContentView(this, R.layout.activity_main);
  User user = new User("Test");
  binding.setUser(user);

}

用户模型

public class User extends BaseObservable {
 private final String name;
 public User(String name){
 this.name = name;
 }
 @Bindable
 public String getName() {
  return name;
 }
}

dataBinding是否不适用于库项目？如果可以,我的设置有什么问题？

谢谢

解决方法:

它确实适用于库项目,但是依赖于使用数据绑定的库的任何应用程序都必须启用数据绑定,即使他们不使用它.
