android - 无法解析 com.android.support :design 28. 0.0

Question

当我想添加 float EditText 时，我在新的 Android Studio 版本中遇到错误。如果我在 gradle 文件中添加这个，我需要添加这个 android.support.design 库

这是我在 logcat 中遇到的错误

Unable to resolve dependency for ':app@debug/compileClasspath': Could not resolve com.android.support:design-v7:28.0.0 Open File Show Details

Unable to resolve dependency for ':app@debugAndroidTest/compileClasspath': Could not resolve com.android.support:design-v7:28.0.0. Open File Show Details

Unable to resolve dependency for ':app@releaseUnitTest/compileClasspath': Could not resolve com.android.support:design-v7:28.0.0. Open File Show Details

注意:我引用了更多链接，即使我没有得到解决方案，我也尝试了所有解决方案。

我已经在 gradle 中取消选中了离线工作。我也在 gradle 文件中添加了 maven 并清理、重建了项目，即使我没有得到解决方案。

这是 gradle 文件:

apply plugin: 'com.android.application'    

repositories {
    maven { url "https://jitpack.io" }


}    

android {
    compileSdkVersion 28
    buildToolsVersion '28.0.3'
    defaultConfig {
        applicationId "fadila.new_tech.app"
        minSdkVersion 16
        targetSdkVersion 28
        versionCode 6
        versionName "1.5"
    }
    buildTypes {
        release {
            minifyEnabled true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }

}

dependencies {

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

    implementation 'com.android.support:support-v4:28.0.0'
    implementation 'com.android.support:appcompat-v7:28.0.0'
    implementation 'com.android.support:design:28.0.0'

}

这是 Gradle(PRjoect 模块)

buildscript {

    repositories {
        google()
        jcenter()
        maven {
            url 'https://maven.google.com' //put it here
        }
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.2.1'


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

allprojects {
    repositories {
        google()
        jcenter()
        maven {
            url 'https://maven.google.com' //put it here
        }
    }
}

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

查看 SDK Manager 镜像 我已经更新了 28 版本

您可以尝试使用加号编译包

implementation 'com.android.support:design:28.0.+'

或者

implementation 'com.android.support:design:28.+'

但是google改了包名， all packages mapping here

All new Support Library development will occur in the AndroidX library

所以你必须使用

implementation 'com.google.android.material:material:1.0.0'

代替

implementation 'com.android.support:design:28.0.+'
