ButterKnife的配置

配置配置Butter Knife 只需要3个步骤: 1. 安装AS插件 Android ButterKnife Zelezny 2. 在项目中添加项目依赖 3. 开始使用注解步骤1首先打开AS, 打开 Settings -> Plugins -> 搜索Android ButterKnife Zelezny, 找到插件点击安装. 我下面的截图是安装之后的, 大家都懂, 不用多解释. 重启生效 步骤2创建Android项目, 分别找到Project Gradle配置文件和Modle Gradle配置文件. 在Project Gradle 配置文件中添加:// 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:2.0.0'        classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8' // 添加这行    }}allprojects {    repositories {        jcenter()    }}task clean(type: Delete) {    delete rootProject.buildDir}再在 Module Gradle配置文件中添加:apply plugin: 'com.android.application'android {    compileSdkVersion 24    buildToolsVersion "24.0.0"    defaultConfig {        applicationId "org.yxm.butterknifesimple"        minSdkVersion 15        targetSdkVersion 24        versionCode 1        versionName "1.0"    }    buildTypes {        release {            minifyEnabled false            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'        }    }}apply plugin: 'com.neenbedankt.android-apt' //添加这行dependencies {    compile fileTree(dir: 'libs', include: ['*.jar'])    testCompile 'junit:junit:4.12'    compile 'com.android.support:appcompat-v7:24.0.0'    compile 'com.jakewharton:butterknife:8.2.1' //添加这行    apt 'com.jakewharton:butterknife-compiler:8.2.1' //添加这行}然后点击 Sync Now, 更新配置, 稍等片刻等待完成 步骤3开始使用 activity_main.xml<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    ...    <TextView        android:id="@+id/tv_1"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:text="TextView" />    <Button        android:id="@+id/btn_1"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:text="Button" /></LinearLayout>MainActivity.javapublic class MainActivity extends AppCompatActivity {    @BindView(R.id.tv_1)    TextView tv1;    @BindView(R.id.btn_1)    Button btn1;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        ButterKnife.bind(this);    }    @OnClick(R.id.tv_1)    void tv1OnClick(View view) {        String content = ((TextView) view).getText().toString();        Toast.makeText(MainActivity.this, "" + content, Toast.LENGTH_SHORT).show();    }    @OnClick(R.id.btn_1)    void btnOnClick() {        Toast.makeText(MainActivity.this, "test", Toast.LENGTH_SHORT).show();    }}@BindView(R.id.tv_1) 绑定控件 @OnClick(R.id.tv_1) 绑定事件注意: 一定记住在 onCreate() 中调用 ButterKnife.bind(this);, 否则不起作用ButterKnife.bind(…)的使用如果在Activity绑定 ButterKnife 使用:@Override public void onCreate(Bundle savedInstanceState) {    super.onCreate(savedInstanceState);    setContentView(R.layout.simple_activity);    ButterKnife.bind(this);    // TODO Use fields...}在Fragment中绑定 ButterKnife使用:@Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {    View view = inflater.inflate(R.layout.fancy_fragment, container, false);    ButterKnife.bind(this, view);    // TODO Use fields...    return view;}在 BaseAdapter的 ViewHodler中使用:  static class ViewHolder {    @BindView(R.id.title) TextView name;    @BindView(R.id.job_title) TextView jobTitle;    public ViewHolder(View view) {      ButterKnife.bind(this, view);    }  }还有很多高级用法, 大家看看上面的官方地址: http://jakewharton.github.io/butterknife/
