From the Butterknife github page:
Add this to you project-level build.gradle:
repositories {
mavenCentral()
}
dependencies {
classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8'
}
}
(update for 8.8.1:
classpath 'com.jakewharton:butterknife-gradle-plugin:8.8.1'
Instead of the old)
Add this to your module-level build.gradle:
android {
...
}
dependencies {
compile 'com.jakewharton:butterknife:8.0.1'
apt 'com.jakewharton:butterknife-compiler:8.0.1'
}
注意app的build.gradle中的顶部apply plugin（处于最外层）
(update for 8.8.1 : try annotationProcessor instead of apt)
Added support for the annotationProcessor configuration provided by Android Gradle Plugin 2.2.0 or later.
升级到Android Studio3.0后，且Android Gradle Plugin 升级到2.2.0后，提供了annotationProcessor及Kotlin的kapt。需替换
apt 'com.jakewharton:butterknife-compiler:8.0.1'
为：
annotationProcessor 'com.jakewharton:butterknife-compiler:8.0.1'
同时删掉apply plugin
使用
View 及 Fragment 中使用:
@Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.*fragment_lcs*, container, false);
ButterKnife.bind(this, rootView);
return rootView;
}
Or in activity使用:
@Override protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState); setContentView(R.layout.*activity_demo*);
ButterKnife.bind(this);
}
成员变量中声明并添加注解，例如：
@BindView(R.id.main_title)
TextView mainTitle;
@BindView(R.id.sub_title)
TextView subTitle;
