android butterknife 未显示生成 butterknife 在 Android Studio4.1.2 中生成注入

android butterknife not showing Generate butterknife generate injections in Android Studio4.1.2

我正在尝试在更新的 android studio 4.1.2 中使用黄油刀,但在 生成 [=27= 中没有得到 生成黄油刀注入 ]选项。

我已经添加了插件:Android ButterKnife Zelezny

构建gradle(项目) /

/ Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
    repositories {
        google()
        jcenter()
        maven { url "https://jitpack.io" }
    }
    dependencies {
        classpath "com.android.tools.build:gradle:4.1.2"
        classpath 'com.google.gms:google-services:4.3.5'
        classpath 'com.jakewharton:butterknife-gradle-plugin:10.2.3'
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        google()
        jcenter()
        maven { url "https://jitpack.io" }
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

build.gradle(模块)

apply plugin: 'com.android.application'

apply plugin: 'com.jakewharton.butterknife'

android {
    compileSdkVersion 30
    buildToolsVersion "30.0.3"

    defaultConfig {
        applicationId "com.a.b"
        minSdkVersion 24
        targetSdkVersion 30
        versionCode 1
        versionName "1.0"

        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
}

dependencies {

    implementation 'androidx.appcompat:appcompat:1.2.0'
    implementation 'com.google.android.material:material:1.3.0'
    implementation 'androidx.constraintlayout:constraintlayout:2.0.4'
    testImplementation 'junit:junit:4.13.1'
    androidTestImplementation 'androidx.test.ext:junit:1.1.2'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.3.0'

    // Import the Firebase BoM
    implementation platform('com.google.firebase:firebase-bom:26.3.0')

    implementation 'com.google.firebase:firebase-crashlytics'
    implementation 'com.google.firebase:firebase-analytics'
    implementation 'com.google.firebase:firebase-firestore'
    implementation 'com.google.firebase:firebase-auth'
    //butterknnife
    implementation 'com.jakewharton:butterknife:10.2.3'
    annotationProcessor 'com.jakewharton:butterknife-compiler:10.2.3'

}

添加所有这些并重新启动后 android studio 在生成中没有获得 butterknife 注入选项

所有依赖声明看起来都很好。请进行干净的构建以解决问题。

仅供参考,您不需要应用 butterknife 插件和

classpath 'com.jakewharton:butterknife-gradle-plugin:10.2.3'

你只需要在应用程序中有以下依赖项build.gradle

implementation 'com.jakewharton:butterknife:10.2.3'
annotationProcessor 'com.jakewharton:butterknife-compiler:10.2.3'

经过尝试和搜索,我发现 Butterknife 已被弃用,因此不会显示

生成 butterknife 注入

单击 R.layout.abc.xml.

时从 生成 选项

解决方案 1

但它仍然有效,只是你必须像下面那样手动声明它

import butterknife.BindView;
import butterknife.ButterKnife;

public class MainActivity extends AppCompatActivity {
    @BindView(R.id.iv_upload)
    ImageView ivUpload;
    @BindView(R.id.textView)
    TextView textView;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.abc);
        ButterKnife.bind(this);
    }
}

作为@CommonsWare 在评论中推荐使用其他东西,

View binding 是当前领先的选择。
