我正在使用androidx库开发一款新的Android应用程序,并且我需要在我的布局中使用cardview。
所以我尝试将cardview库添加到我的项目中,但是我遇到了以下错误
例如:
所以我尝试将cardview库添加到我的项目中,但是我遇到了以下错误
ERROR: Failed to resolve: cardview
我查看了“Failed: com.android.support:cardview-v7:26.0.0 android”的答案,但这并没有帮助我例如:
- 在
jcenter()
之前添加google()
- 将
maven { url“ https://maven.google.com” } 添加到
repositories 中
build.gradle(project)
apply plugin: 'com.android.application'
android {
compileSdkVersion 28
defaultConfig {
applicationId "com.chavosh.porterageapp"
minSdkVersion 14
targetSdkVersion 28
versionCode 1
versionName "1.0"
testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
vectorDrawables.useSupportLibrary = true
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
implementation fileTree(include: ['*.jar'], dir: 'libs')

testImplementation 'junit:junit:4.12'
// recycler view

}
build.gradle(moudle)
// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
repositories {
google()
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.3.0'
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:1.3.21"
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
google()
jcenter()
mavenCentral()
maven { url 'https://jitpack.io' }
maven { url "https://maven.google.com" }
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}
gradle.properties有以下两行
android.useAndroidX=true
android.enableJetifier=true
gradle.properties
文件中添加android.useAndroidX=true android.enableJetifier=true
。另外,请查看此链接:https://stackoverflow.com/questions/52181574/android-failed-to-resolve-cardview-v7 还请查看https://developer.android.com/jetpack/androidx/migrate,它可以为您提供更多帮助。 - Ajay Mehtagradle.properties
文件中有android.useAndroidX=true android.enableJetifier=true
