错误：（34,12）无法解决：com.android.support:recycleview-v7:26.0.0-alpha1

Question

当我使用recycleview时发现此错误 错误：（34,12）无法解决：com.android.support:recycleview-v7:26.0.0 安装存储库和同步项目
在文件中显示
在项目结构对话框中显示 compile'c​​om.android.support：recycleview-v7：26.0.0'和compile'c​​om.android.support：recycleview-v7：26.0.0-alpha1'我试试，但他们都不能成功。谁可以帮助我

这是gralde文件：     apply plugin：'com.android.application'

android {
    compileSdkVersion 26
    buildToolsVersion "26.0.0"
    defaultConfig {
        applicationId "com.example.exploapplication"
        minSdkVersion 21
        targetSdkVersion 26
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    compile 'com.android.support:appcompat-v7:26.+'
    compile 'com.android.support.constraint:constraint-layout:1.0.1'
    testCompile 'junit:junit:4.12'
    compile'com.squareup.okhttp3:okhttp:3.4.1'
    compile'com.google.code.gson:gson:2.7'
    compile'com.android.support:design:26.0.0-alpha1'
    compile'de.hdodenhof:circleimageview:2.1.0'
    compile'com.android.support:cardview-v7:26.0.0-alpha1'
    compile'com.android.support:recycleview-v7:26.0.0'
}

其他gradle： //顶级构建文件，您可以在其中添加所有子项目/模块共有的配置选项。

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.3.3'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

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

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

Answer 1

在maven区块中：

在url＆amp;之间留出空格"https://maven.google.com"

它应该如下所示：url "https://maven.google.com"

接下来，

1. 从Android Stuido转到Android SDK
2. 点击右下角的Show Package Details
3. 点击Android SDK Build-Tools的最新版本，Android SDK Platform-Tools＆amp; Android SDK Tools（查看随附的屏幕截图）
4. 安装Android Support Repository＆amp; Google Repository如果您没有

compile 'com.android.support:appcompat-v7:26.1.0'

1. 替换compile'com.android.support:design:26.0.0-alpha1'

compile'com.android.support:design:26.1.0'

1. 替换compile'com.android.support:cardview-v7:26.0.0-alpha1'

compile'com.android.support:cardview-v7:26.1.0'
