Kotlen_DataBinding_配置

新增的Kotlin项目需要使用DataBinding的时候要在module的build.gradle中添加如下配置

1,启用DataBinding, 跟使用java语言时一样的配置

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

2,dependencies 添加插件

dependencies {
...
    //kotlin使用DataBinding需要用到, 版本跟gradle一致
    kapt "com.android.databinding:compiler:$gradle_version"
}

3,文件末尾添加插件配置

kapt {
    generateStubs = true
}

module的build.gradle举例如下

apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-android-extensions'

android {
    buildToolsVersion androidBuildTools
    compileSdkVersion androidTargetSdk

    defaultConfig {
        applicationId "com.xxx.xxx"
        minSdkVersion 19
        targetSdkVersion androidTargetSdk
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }

    buildTypes {
        release {
            //minifyEnabled false
            //proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    dexOptions {
        incremental true
    }
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
    dataBinding {
        enabled = true
    }
}

dependencies {
    implementation fileTree(include: ['*.jar'], dir: 'libs')
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jre7:$kotlin_version"
    //kotlin使用DataBinding需要用到, 版本跟gradle一致
    kapt "com.android.databinding:compiler:$gradle_version"
    //design
    compile 'com.android.support:design:25.3.1'
    //retrofit,OKHttp3
    compile 'com.squareup.retrofit2:retrofit:2.1.0'
    compile 'com.squareup.retrofit2:adapter-rxjava2:2.3.0'
    //Retrofit2使用gson序列化
    compile 'com.squareup.retrofit2:converter-gson:2.1.0'
    //okhttp3拦截器
    compile 'com.squareup.okhttp3:logging-interceptor:3.4.1'
    //GSON
    compile 'com.google.code.gson:gson:2.8.0'
}

//kotlin使用DataBinding需要用到
kapt {
    generateStubs = true
}

project的build.gradle举例如下

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    ext.kotlin_version = '1.1.51'
    ext.gradle_version = '3.0.1'
    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath "com.android.tools.build:gradle:$gradle_version"
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"

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

allprojects {
    repositories {
        google()
        jcenter()
    }
    ext.androidBuildTools = '27.0.3'
    ext.androidTargetSdk = 25
}

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