Question

我在最新的支持库中遇到了奇怪的问题。我刚刚将我的项目迁移到GOOGLE提供的最新支持版本，并根据谷歌指南

所以问题是无法在最新的支持文件中找到 cardView 。有人面临这个问题吗？

这是我的App Gradle文件

apply plugin: 'com.android.application'

android {
    compileSdkVersion 'android-O'
    buildToolsVersion "26.0.0-rc2"
    defaultConfig {
        applicationId "com.temp"
        minSdkVersion 15
        targetSdkVersion 26
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    dataBinding {
        enabled = true
    }
    lintOptions {
        disable 'RestrictedApi'
        checkReleaseBuilds false
        // Or, if you prefer, you can continue to check for errors in release builds,
        // but continue the build even when errors are found:
        abortOnError false
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile "com.android.support:appcompat-v7:$support_libs"
    compile "com.android.support:design:$support_libs"
    compile 'com.android.support.constraint:constraint-layout:1.0.2'

    compile 'jp.wasabeef:blurry:2.1.1'
}

// REQUIRED: Google's new Maven repo is required for the latest
// support library that is compatible with Android O
repositories {
    maven {
        url 'https://maven.google.com'
        // Alternative URL is 'https://dl.google.com/dl/android/maven2/'
    }
}

这是项目gradle

    // Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    ext.support_libs = '26.0.0-beta1'
    repositories {
        maven { url 'https://maven.google.com' }
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.0.0-alpha2'

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

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

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

Answer 1

我没有在应用程序gradle文件的任何位置添加 cardview 添加到依赖项。尝试添加：

C:\wamp64\www\public_html\step C:\wamp64\www\public_html C:\wamp64\www C:\wamp64

Answer 2

在gradle文件中添加这些依赖项：

compile 'com.android.support:appcompat-v7:25.2.0'
compile 'com.android.support:design:25.2.0'
compile 'com.android.support:cardview-v7:25.2.0'

Answer 3

AppCompat v7不包含CardView，您需要在依赖项中明确声明该lib。

因此，请将compile 'com.android.support:cardview-v7:$support_libs'添加到您的依赖项中。
