ButterKnife的注入

添加依赖

Configure your project-level build.gradle to include the ‘android-apt’ plugin:

buildscript {  repositories {    mavenCentral()   }  dependencies {    classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8'  }}

Then, apply the ‘android-apt’ plugin in your module-level build.gradle and add the Butter Knife dependencies:

apply plugin: 'android-apt'android {  ...}dependencies {  compile 'com.jakewharton:butterknife:8.4.0'  apt 'com.jakewharton:butterknife-compiler:8.4.0'}

Activity注入

@Overrideprotected void onCreate(Bundle savedInstanceState) {    super.onCreate(savedInstanceState);    setContentView(R.layout.activity_main);    ButterKnife.bind(this);}

Fragment注入

@Overridepublic View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {    View view = inflater.inflate(R.layout.keybord_normal_fragment, container, false);    ButterKnife.bind(this, view);    return view;}

ViewHolder注入

static class ViewHolder {@Bind(R.id.name) TextView name;@Bind(R.id.password) TextView pwd;    public ViewHolder(View view) {      ButterKnife.bind(this, view);    }}

其余绑定

//资源绑定：@BindColor(R.color.red) int red; //控件绑定：@BindView(R.id.home_show_content_tv)    TextView mTvShowContent;onClick事件绑定:@OnClick({R.id.cal_num_1_btn, R.id.cal_num_2_btn})public void click(View view){...}
