Question

这就是我的结果所以错误运行代码..

Exception in thread "main" java.lang.ClassNotFoundException: pya.marlon.com.pruebas.ExampleRXJava
    at java.net.URLClassLoader.findClass(URLClassLoader.java:381)
    at java.lang.ClassLoader.loadClass(ClassLoader.java:424)
    at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:331)

    at java.lang.Class.forName(Class.java:264)
    at com.intellij.rt.execution.application.AppMain.main(AppMain.java:123)

Process finished with exit code 1

使用一些示例RXJava可能会遇到gradle代码问题..

apply plugin: 'com.android.application'

android {
    compileSdkVersion 25
    buildToolsVersion "25.0.3"
    defaultConfig {
        applicationId "pya.marlon.com.pruebas"
        minSdkVersion 19
        targetSdkVersion 25
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"

        jackOptions{
            enabled true
        }
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }

    sourceSets {
        main {
            java.srcDirs = ['src/main/java', 'src/main/java-gen', '../greendao/classes']
        }
    }
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
}

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 project(':greendao')
    compile 'com.android.support:appcompat-v7:25.3.1'

    compile 'com.android.support:design:25.3.1'
    compile 'io.reactivex:rxjava:1.3.0'
}

我的Android Studio有什么问题所以版本是2.3.2 我在项目中使用了两个模块

Answer 1

请正确阅读异常消息，它清楚地显示找不到pya.marlon.com.pruebas.ExampleRXJava课程，可能您没有包含上述课程。

找到关于RxJava的一个非常好的教程

Answer 2

要在Android中使用RxJava，请将以下依赖项添加到build.gradle文件中。

compile 'io.reactivex.rxjava2:rxandroid:2.0.1'
compile 'io.reactivex.rxjava2:rxjava:2.0.8
