AndroidStudio3.2.0使用ButterKnife插件

工作环境(蓝色粗体字为特别注意内容)
1，系统环境：Win7 Ultimate sp1
2、开发环境：AndroidStudio 3.2.1、JDK8u11
3、参考文献：https://www.jianshu.com/p/c61172bfa49b、https://blog.csdn.net/sxk874890728/article/details/78367726

Step1：打开File->Settings->Plugins

Step2:在搜索框中搜索ButterKnife， 再点击search in respositories,选择Android ButterKnife zelezny,最后点击Install.

Step3:在build.gredle（Project）文件中的dependencies标签下添加：

dependencies {
    classpath 'com.android.tools.build:gradle:3.2.0'
    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
}

Step4:在app的build.gredle 中添加：

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.android.support:appcompat-v7:27.1.1'
    implementation 'com.android.support.constraint:constraint-layout:1.1.3'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'

    compile 'com.jakewharton:butterknife:8.4.0'
    annotationProcessor 'com.jakewharton:butterknife-compiler:8.4.0'
}

sync一下，测试例程：

@BindView(R.id.hello)
TextView textView;

 setContentView(R.layout.activity_main);
 ButterKnife.bind(this);

textView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Toast.makeText(MainActivity.this,"hello",Toast.LENGTH_LONG).show();
            }
        });

注：如果写成“ apt 'com.jakewharton:butterknife-compiler:8.4.0'”会出现报错：
android-apt plugin is incompatible with the Android Gradle plugin. Please use 'annotationProcessor'
