前言
ButterKnife 簡介
ButterKnife是一個專注于Android的View注入框架,可以減少大量的findViewById以及setOnClickListener代碼，可視化一鍵生成。
項目github地址：https://github.com/JakeWharton/butterknife
ButterKnife 優勢
1、強大的View綁定和Click事件處理功能，簡化代碼，提升開發效率
2、方便的處理Adapter里的ViewHolder綁定問題
3、運行時不會影響APP效率，使用配置方便
4、代碼清晰，可讀性強
如何添加依賴
buildscript
{repositories {jcenter()}dependencies
{classpath 'com.android.tools.build:gradle:2.2.2'classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8'}
}allprojects
{repositories {jcenter()}
}task clean(type: Delete)
{delete rootProject.buildDir
}
在module的build.gredle 文件中添加
apply plugin: ‘android-apt’
在module的build.gredle 文件中的dependencies標簽中添加
compile ‘com.jakewharton:butterknife:8.4.0’
apt ‘com.jakewharton:butterknife-compiler:8.4.0’
例如
apply plugin:
'com.android.application'
apply plugin:
'android-apt'android {compileSdkVersion
24buildToolsVersion
"24.0.3"defaultConfig {applicationId
"com.zyj.wifi"minSdkVersion
14targetSdkVersion
24versionCode
1versionName
"1.0"}buildTypes {release {minifyEnabled
falseproguardFiles getDefaultProguardFile(
'proguard-android.txt'),
'proguard-rules.pro'}}
}dependencies {compile fileTree(
dir:
'libs', include: [
'*.jar'])compile
'com.jakewharton:butterknife:8.4.0'apt
'com.jakewharton:butterknife-compiler:8.4.0'
}

false);ButterKnife.bind(
this , view ) ;button1.setText(
"I am a button ");
return view ;}
}
- @BindString() ：綁定string 字符串

@Overrideprotected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);setContentView(R.layout.activity_butterknife);ButterKnife.bind(
this ) ;button1.setText( meg );}
}
- @BindArray() : 綁定string里面array數組
<resources><string name=
"app_name">WiFi管家</string><string-array name=
"city"><item>廈門市</item><item>福州市</item><item>泉州市</item><item>漳州市</item><item>龍巖市</item></string-array></resources>

import butterknife.ButterKnife;public
class ButterknifeActivity extends AppCompatActivity {@BindView( R.id.button1 ) public Button button1 ;
@BindArray(R.array.city ) String [] citys ;
@Overrideprotected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);setContentView(R.layout.activity_butterknife);ButterKnife.bind(
this ) ;button1.setText( citys[
0] );}
}

"is a click", Toast.LENGTH_SHORT).show();}
@OnLongClick( R.id.button1 )
public boolean showToast2(){Toast.makeText(
this,
"is a long click", Toast.LENGTH_SHORT).show();
return true ;}

}
- zelezny : Butterknife插件的使用
插件的安裝
插件的使用
安裝完成插件后，會提示重啟AS，重啟完后，可以寫一個布局并且新建一個代碼類測試下。測試的過程中要注意的是，需要將光標移到setContentView(R.layout.acty_login)，將光標放到R.layout.acty_login，然后右鍵Generate就有了。要注意一定要將光標放在R.layout.acty_login上面。
這里需要注意的是在勾選控件的界面上，有一個CreateViewHolder , 很明顯這個是專門為ListView或者RecyclerView的適配器專門提供的。
