升级Android Studio 2.3后DataBinding不起作用 [英] DataBinding not working after Upgrade Android Studio 2.3

问题描述

DataBinding在我的项目中工作得很好，但是在升级Android Studio 2.3之后。 运行'app'失败，因为以下错误：

 错误：（15，40）错误：包com.javan.myrecorder.databinding不存在。 
 import com.javan.myrecorder.databinding.FragmentEventsBinding; 
：app：compileMockDebugJavaWithJavac FAILED 
  

我只是升级android studio，没有改变任何东西。所有插件都是最新的！现在我的问题是，为什么会出现这个错误，我该怎么解决呢？欢迎任何帮助！

英语不是我的母语;请原谅我的错误。

像android项目 googlesamples / android-architecture

• git checkout todo-databinding


• 然后运行 ./ gradlew由于以下错误，assembleDebug 构建失败：

EDIT2 我已经通过以下数据绑定在升级到Gradle 2.3之后破解

在 build.gradle（app）添加

 应用插件：'com.android.application'
应用插件：'com。 neenbedankt.android-apt'
 
 ..balabala 
 
依赖关系{
 apt'com.android.databinding：编译器：2.3.0'
} 
  pre> 
 
 
我项目中的一些文件：
 
 
 
  gradle-wrapper.properties  
  #Mon Mar 06 10:59:04 CST 2017 
 distributionBase = GRADLE_USER_HOME 
 distributionPath = wrapper / dists 
 zipStoreBase = GRADLE_USER_HOME 
 zipStorePath = wrapper / dists 
 distributionUrl = https\：//services.gradle.org/distributions/gradle-3.3-all.zip

解决方案
  android-apt 因此使用 apt 自从Android Studio 2.2以来，它们已被淘汰。
 
遵循 android-apt迁移指南，而是将以下内容添加到您的 build.gradle 中：
  dependenci es {
 annotationProcessor'com.android.databinding：compiler：2.3.0'
} 
  
如果您使用Kolin，请使用：
 应用插件：'kotlin-kapt'
 
依赖关系{
 kapt'com.android.databinding：编译器：2.3.0'
} 
  
 
DataBinding worked very well in my project,  But after upgrade Android Studio 2.3 today . Run 'app' failed because following error : 
Error:(15, 40) Error: package com.javan.myrecorder.databinding not exist.
import com.javan.myrecorder.databinding.FragmentEventsBinding;
:app:compileMockDebugJavaWithJavac FAILED
I just upgrade android studio and didn't change anything. all plugin is latest! Now my question is, why occurs this error and how could I solve it? any help is welcome!


English is not my mother tongue; please excuse any errors on my part.



EDIT1

Like android project googlesamples/android-architecture


git checkout todo-databinding 
and then run ./gradlew assembleDebug to build, build failed because of following error:


complete log of build



EDIT2 I have fixed this problem by following Data Binding broke after upgrade to Gradle 2.3.

in build.gradle(app) add 
apply plugin: 'com.android.application'
apply plugin: 'com.neenbedankt.android-apt'

..balabala

dependencies {
    apt 'com.android.databinding:compiler:2.3.0'
}
some file in my project:

gradle-wrapper.properties
#Mon Mar 06 10:59:04 CST 2017
distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists
distributionUrl=https\://services.gradle.org/distributions/gradle-3.3-all.zip
@petrnohejl @George Mount @Sa-Zad Prasla, Thanks!
解决方案
android-apt and hence using apt is effectively deprecated since Android Studio 2.2.

Following the android-apt migration guide, instead add the following to your build.gradle:
dependencies {
    annotationProcessor 'com.android.databinding:compiler:2.3.0'
}
If you are using Kolin instead use:
apply plugin: 'kotlin-kapt'

dependencies {
    kapt 'com.android.databinding:compiler:2.3.0'
}
