升级 Android Studio 2.3 后数据绑定不起作用

问题描述：

DataBinding 在我的项目中运行良好，但今天升级 Android Studio 2.3 后.运行'app'失败，因为以下错误:

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

我只是升级了 android studio 并没有改变任何东西.所有插件都是最新的！现在我的问题是，为什么会出现此错误，我该如何解决?欢迎任何帮助！

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!

英语不是我的母语；请原谅我的任何错误.

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

喜欢 android 项目 googlesamples/android-architecture

Like android project googlesamples/android-architecture

git checkout todo-databinding
然后运行./gradlew assembleDebug编译，编译失败，错误如下:

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

完整的构建日志

EDIT2 我已经按照升级到 Gradle 2.3 后数据绑定中断.

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

在build.gradle(app)中添加

apply plugin: 'com.android.application'
apply plugin: 'com.neenbedankt.android-apt'

..balabala

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

我的项目中的一些文件:

some file in my project:

gradle-wrapper.properties

答

android-apt 因此使用 apt 自 Android Studio 2.2 起已被弃用.
按照 android-apt 迁移指南，将以下内容添加到您的 build.gradle:

android-apt and hence using apt has been deprecated since Android Studio 2.2.
Following the android-apt migration guide, instead add the following to your build.gradle:

dependencies {
    classpath 'com.android.tools.build:gradle:2.3.0' // use same gradle version!
    annotationProcessor 'com.android.databinding:compiler:2.3.0'
}

如果您使用的是 Kolin，请改用:

If you are using Kolin, instead use:

apply plugin: 'kotlin-kapt'

dependencies {
    classpath 'com.android.tools.build:gradle:2.3.0' // use same gradle version!
    kapt 'com.android.databinding:compiler:2.3.0'
}
