今天了解下butterknife注解框架使用，省去了findViewById,onClick代码的拼写

git上的开源项目链接如下：
https://github.com/JakeWharton/butterknife/

我们就进行一些配置吧：
在Module中build.gradle进行如下配置

apply plugin: 'com.neenbedankt.android-apt'

dependencies {    compile 'com.jakewharton:butterknife:8.2.1'    apt 'com.jakewharton:butterknife-compiler:8.2.1'}

我们需要在Project的build.gradle中配置如下代码：

    dependencies {        classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8'    }

主界面就2个TextView控件

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:orientation="vertical"    tools:context="com.example.administrator.myapplication.MainActivity">    <TextView        android:id="@+id/textView1"        android:background="#ccc"        android:gravity="center"        android:layout_width="fill_parent"        android:layout_height="50dp"        android:text="Hello World!1" />    <TextView        android:id="@+id/textView2"        android:background="#999"        android:gravity="center"        android:layout_width="fill_parent"        android:layout_height="50dp"        android:text="Hello World!2" /></LinearLayout>

在MainActivity中

package com.example.administrator.myapplication;import android.app.Activity;import android.support.v7.app.AppCompatActivity;import android.os.Bundle;import android.util.Log;import android.view.View;import android.widget.TextView;import android.widget.Toast;import org.w3c.dom.Text;import java.util.ArrayList;import butterknife.BindColor;import butterknife.BindString;import butterknife.BindView;import butterknife.BindViews;import butterknife.ButterKnife;import butterknife.OnClick;public class MainActivity extends Activity {    @BindView(R.id.textView1) TextView textView1;    @BindView(R.id.textView2) TextView textView2;    @BindColor(R.color.colorAccent) int color;    @BindString(R.string.app_name) String myStr;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        ButterKnife.bind(this);        Log.i("MainActivity","color:"+color+",myStr:"+myStr);    }    @OnClick({R.id.textView1,R.id.textView2})    public void myOnClick1(View view){        switch (view.getId()){            case R.id.textView1:                Log.i("MainActivity", "textView1 onclick");                break;            case R.id.textView2:                Log.i("MainActivity", "textView2 onclick");                break;        }    }}

log输出
