Macbook下Android studio的butterknife的应用

android studio 版本1.2.1
1. 在build.gradle中增加加粗的语句，butterknife的版本为6.1.0

apply plugin: 'com.android.application'

android {
    compileSdkVersion 21
    buildToolsVersion "21.1.2"

    defaultConfig {
        applicationId "com.example.wuqiong.demo"
        minSdkVersion 10
        targetSdkVersion 21
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:22.1.1'
    **compile 'com.jakewharton:butterknife:6.1.0'**
}

2.点击工具栏中的“同步gradle文件“按钮；
3.修改activity文件， ButterKnife.inject(this)这一句一定不要忘了。

public class MainActivity extends ActionBarActivity {
@InjectView(R.id.tv)
    TextView mTv;

@InjectView(R.id.btn)
    Button mBtn;

@OnClick(R.id.btn)
void display() {
        mTv.setText("aaaa");
    }

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        ButterKnife.inject(this);

        mTv.setText("bbbb");
    }

}
