Question

Android Studio 3.0

在project / build.gradle中

：

classpath 'com.android.tools.build:gradle:3.0.1'

在app / build.gradle中

：

buildscript {
    repositories {
        maven { url 'https://maven.fabric.io/public' }
    }

    dependencies {
        classpath 'io.fabric.tools:gradle:1.+'
    }
}
apply plugin: 'com.android.application'
apply plugin: 'io.fabric'
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-kapt'
apply plugin: 'realm-android'

def keystoreProperties = new Properties()
keystoreProperties.load(new FileInputStream(rootProject.file("app/keystore.properties")))

android {
    dataBinding {
        enabled = true
    }
    compileSdkVersion 26
    defaultConfig {
        applicationId "com.myproject.android.customer"
        minSdkVersion 15
        targetSdkVersion 26
        versionCode 1
        versionName "0.1.1"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"

        //multiDexEnabled true
    }
    signingConfigs {
        release {
            keyAlias keystoreProperties['KEY_ALIAS_RELEASE']
            keyPassword keystoreProperties['KEY_PASSWORD_RELEASE']
            storeFile file(keystoreProperties['STORE_FILE_RELEASE'])
            storePassword keystoreProperties['STORE_PASSWORD_RELEASE']
        }
    }

    /*- exclude buildTypes = "debug" from build Variants
    variantFilter { variant ->
        if (variant.buildType.name.equals('debug')) {
            variant.setIgnore(true);
        }
    }*/


    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'

            // sign settings
            signingConfig signingConfigs.release

            // config Fabrice (Beta of Crashlytics)
            ext.betaDistributionReleaseNotes = defaultConfig.versionName + " " + name
            ext.betaDistributionEmailsFilePath = "app/beta_distribution_emails.txt"
        }
        debug {
            ext.alwaysUpdateBuildId = false // not need CrashLytics on debug mode

        }
    }

}

依赖{ 实现fileTree（dir：'libs'，包括：['* .jar']）

implementation('com.crashlytics.sdk.android:crashlytics:2.7.0@aar') { transitive = true; }

implementation 'com.android.support.constraint:constraint-layout:1.0.2'

// test dependencies
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.1'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.1'

}

repositories {
    mavenCentral()
    maven { url 'https://maven.fabric.io/public' }
}

我的布局名称是：offer_item.xml。

因此，结果绑定文件名为：OfferItemBinding

这里是我的RecyclerViewAdapter：

import com.myproject.android.customer.databinding.OfferItemBinding;

    public OfferSortAdapter.OfferViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
            LayoutInflater inflater = LayoutInflater.from(parent.getContext());
            OfferItemBinding binding = OfferItemBinding.inflate(inflater, parent, false);
            return new OfferViewHolder(binding.getRoot(), this);
        }

这里是xml布局：

<?xml version="1.0" encoding="utf-8"?>
<layout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools">

    <data>

        <variable
            name="offer"
            type="com.myproject.android.customer.api.model.Offer" />
    </data>
</layout>

未生成文件OfferItemBinding。

我得到错误：

    D:\dev\MyProject\app\src\main\java\com\myproject\android\customer\ui\adapter\OfferSortAdapter.java:29:

error: package com.myproject.android.customer.databinding does not exist
    import com.myproject.android.customer.databinding.OfferItemBinding;

在build.gradle
中试试

    dependencies {
        //for butterknife
        implementation 'com.jakewharton:butterknife:8.8.1'
        kapt 'com.jakewharton:butterknife-compiler:8.8.1'

        implementation "org.jetbrains.kotlin:kotlin-stdlib-jre7:$kotlin_version"
        kapt "com.android.databinding:compiler:2.3.3"
    }


apply plugin: 'kotlin-android-extensions'
apply plugin: 'kotlin-kapt'
apply plugin: 'kotlin-android'

kapt {
    generateStubs = true
}

在您的RecylerviewAdpater中

public class MyViewHolder extends RecyclerView.ViewHolder {
private final ItemBinding binding;

public MyViewHolder(ItemBinding binding) {
    super(binding.getRoot());
    this.binding = binding;
}

public void bind(Item item) {
    binding.setItem(item);
    binding.executePendingBindings();
}
}

现在，我的适配器可以使用Android数据绑定创建和绑定：

    public MyViewHolder onCreateViewHolder(ViewGroup parent,
                                       int viewType) {
    LayoutInflater layoutInflater =
        LayoutInflater.from(parent.getContext());
    ItemBinding itemBinding = 
        ItemBinding.inflate(layoutInflater, parent, false);
    return new MyViewHolder(itemBinding);
}

public void onBindViewHolder(MyViewHolder holder, int position) {
    Item item = getItemForPosition(position);
    holder.bind(item);
}

数据绑定：ButterKnife，Kotlin：不生成绑定文件
