android - 在我的项目中使用 Gradle android.support.v7.widget.CardView 依赖项时出错(IIntelliJ IDEA)

Question

当我在 IDEA IIntelliJ 中创建项目时，出现此错误

Error:Gradle: A problem occurred configuring project ':app'. Could not download artifact 'com.android.support:cardview-v7:21.0.0-rc1:cardview-v7.jar' Artifact 'com.android.support:cardview-v7:21.0.0-rc1:cardview-v7.jar' not found.

这就是我做的

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:cardview-v7:+'
}

Answer 1

如果你想使用 CardView 或 RecyclerView 我认为你需要在你的 build.gradle 文件中这样的东西:

apply plugin: 'com.android.application'
android 
{
    compileSdkVersion 'android-L'
    buildToolsVersion '20.0.0'
    [...]
}
dependencies 
{
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:cardview-v7:+'
    compile 'com.android.support:recyclerview-v7:+'
}
