butterknife8.5.1配android-butterknife-zelezny1.6.0
github地址(里面有安装方法):
https://github.com/JakeWharton/butterknife
https://github.com/avast/android-butterknife-zelezny
butterknife用注解的方式代替findViewById和OnClick等.
android-butterknife-zelezny是自动生成这些代码的一个插件.
- butterknife安装
按照github上面的教程就行,我直接代码.
apply plugin: 'com.android.application'
apply plugin: 'com.jakewharton.butterknife'
android {
compileSdkVersion 26
buildToolsVersion "26.0.1"
defaultConfig {
applicationId "com.application.imooc_butter_knife"
minSdkVersion 14
targetSdkVersion 26
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
implementation fileTree(include: ['*.jar'], dir: 'libs')
implementation 'com.android.support:appcompat-v7:26.0.2'
implementation 'com.android.support.constraint:constraint-layout:1.0.2'
compile 'com.jakewharton:butterknife:8.5.1'
annotationProcessor 'com.jakewharton:butterknife-compiler:8.5.1'
testImplementation 'junit:junit:4.12'
androidTestImplementation('com.android.support.test.espresso:espresso-core:3.0.1', {
exclude group: 'com.android.support', module: 'support-annotations'
})
implementation 'com.android.support:recyclerview-v7:26.0.2'
}
2个地方 一个是最上面
apply plugin: 'com.jakewharton.butterknife'
一个是下面依赖里
compile 'com.jakewharton:butterknife:8.5.1'
annotationProcessor 'com.jakewharton:butterknife-compiler:8.5.1'
然后在项目的那个build.gradle里
// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
repositories {
google()
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.0.0-beta5'
classpath 'com.jakewharton:butterknife-gradle-plugin:8.5.1'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
google()
jcenter()
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}
在依赖里添加一行:
classpath 'com.jakewharton:butterknife-gradle-plugin:8.5.1'
ok,完成了.
在MainActivity里测试
@BindView(R.id.a1)
TextView mTv;
@BindView(R.id.a2)
Button mBtn1;
@BindView(R.id.a3)
Button mBtn2;
- android-butterknife-zelezny 在as的插件里,如图

下载最新的就行,但是装完了,让我重启,重启完了发现插件没了.我上网查了一下,发现是as是从system下找插件,而我修改了这个路径,所以找不到了.
这个帖子里说的很清楚了.只要不修改插件的路径即可.
idea.plugins.path=${idea.system.path}/plugins

修改完重启,进入Mainactivity测试.光标一定要在id上右键generate或者ait+insert

在adapter上试验下,在红框上alt+insert,自动生成ViewHolder,完美 :
image.png
static class ViewHolder {
@BindView(R.id.i1)
TextView mTextView;
ViewHolder(View view) {
ButterKnife.bind(this, view);
}
}
最后说一下版本的问题,Zelezny最新是1.6,配ButterKnife最新8.8.1出现错误,然后往下调版本,调到8.5.1没问题.
