AndroidStudio之ButterKnife

为什么要用AS呢，上篇已经说过了，那现在就来体验下AS吧！

首先来个插件，butterknife，有了它，不必再用findViewById查找控件了。

点击File——>Settings

点击Plugins，输入框输入butterknife

选第一个点击下载重启

配置如下，首先是app下的build.gradle

apply plugin: 'com.android.application'
//这里butterknife
apply plugin: 'android-apt'

android {
    compileSdkVersion 
    buildToolsVersion "25.0.0"
    defaultConfig {
        applicationId "com.yuan.mvp"
        minSdkVersion 
        targetSdkVersion 
        versionCode 
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }


}

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    compile 'com.android.support:appcompat-v7:25.0.0'
    testCompile 'junit:junit:4.12'
    //还有这里butterknife
    compile 'com.jakewharton:butterknife:8.4.0'
    apt 'com.jakewharton:butterknife-compiler:8.4.0'
    //到这里
}
           

其次是工程下的build.gradle

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

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.2.2'
        //这里butterknife
        classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8'

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

allprojects {
    repositories {
        jcenter()
    }
}

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

使用

在Activity类的布局文件那

按下Alt+Ins键就弹出

点击红色区域弹出选择就好了，第一列是代替findViewById了，第二列代替的是onclick

好了，就这样，方便的插件
