高版本butterknife配置

只需要在module的build.gradle文件中加入下列代码即可：

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    compile 'com.android.support:appcompat-v7:25.1.1'
    testCompile 'junit:junit:4.12'
    compile 'com.jakewharton:butterknife:8.5.1'                       // 添加这行
    annotationProcessor 'com.jakewharton:butterknife-compiler:8.5.1'  // 添加这行

}
