为什么我不能导入LinearLayoutManager和RecyclerView？

Question

I can import everything else from the Android library except for those two. I'm trying to import them from android.support.v7.widget which doesn't work, but importing fragment and activity classes from android.support.v4.widget does work.

My Gradle Build looks like this:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 22
    buildToolsVersion "22.0.1"

    defaultConfig {
        applicationId "com.frisosapps.planner"
        minSdkVersion 14
        targetSdkVersion 22
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:22.2.1'
    compile 'com.android.support:support-v4:22.2.1'
}

Should I add something to this or should I look for the cause elsewhere?

Answer 1

要使用RecyclerView ，请使用compile 'com.android.support:recyclerview-v7:23.1.1'

Answer 2

您需要将RecyclerView依赖项作为其独立库包含在内

compile "com.android.support:recyclerview-v7:23.1.1"
