Question

Android Studio 3.4.2

build.gradle：

buildscript {
    ext.kotlin_version = '1.3.41'
    repositories {
        google()
        jcenter()

    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.4.2'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

在app / build.gradle中：

    def AAVersion = '4.6.0'
def KOTLIN_COROUTINE_VERSION = '1.2.1'

    dependencies {
        annotationProcessor "org.androidannotations:androidannotations:$AAVersion"

        implementation fileTree(dir: 'libs', include: ['*.jar'])

        implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
        implementation 'com.android.support:appcompat-v7:28.0.0'
        implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
        implementation 'com.android.support.constraint:constraint-layout:1.1.3'
        implementation('com.crashlytics.sdk.android:crashlytics:2.7.0@aar') { transitive = true; }
        implementation 'com.google.android.material:material:1.1.0-alpha07'
        implementation 'com.google.code.gson:gson:2.8.5'
        implementation "org.androidannotations:androidannotations-api:$AAVersion"
    implementation "org.jetbrains.kotlinx:kotlinx-coroutines-android:$KOTLIN_COROUTINE_VERSION"
        implementation "org.jetbrains.kotlinx:kotlinx-coroutines-core:$KOTLIN_COROUTINE_VERSION"

    }

我有活动（ java类），其注释为org.androidannotations.annotations.EActivity

以下代码段：

import android.app.Activity;
import android.os.Bundle;
import org.androidannotations.annotations.EActivity

@EActivity
public class LoginActivity extends Activity {

}

另一个Java活动（ SplashActivity.java ）像这样调用此LoginActivity：

import android.app.Activity;
import android.os.Bundle;
import org.androidannotations.annotations.EActivity

@EActivity
public class SplashActivity extends Activity {


Intent intent = new Intent(thisActivity, LoginActivity_.class);
startActivity(intent);

很好，工作正常。

现在，我仅将 LoginActivity 迁移到Kotlin类（LoginActivity.kt）

像这样：

import org.androidannotations.annotations.Background
import org.androidannotations.annotations.EActivity

@EActivity
open class LoginActivity : Activity() {

}

现在 SplashActivity.java 在此行中有编译错误：

Intent intent = new Intent(thisActivity, LoginActivity_.class);

错误消息：

Cannot resolve symbol 'LoginActivity_'

P.S。如果我删除“ _”而不是编译成功：

Intent intent = new Intent(thisActivity, LoginActivity.class);

但是我需要使用LoginActivity_

您必须use kapt而不是annotationProcessor来处理Kotlin文件。任何注释处理器可能会或可能不会正确处理它们； androidannotations，尤其是there is documentation on Kotlin support。

将Java类迁移到Kotlin-无法解析符号注释类
