android - RecyclerView ClassNotFound

Question

我尝试将 RecyclerView 和 CardView 添加到我的项目中

dependencies {
compile 'com.android.support:appcompat-v7:21.0.0'
compile 'com.android.support:support-v13:21.0.0'
compile 'com.android.support:cardview-v7:21.0.0'
compile 'com.android.support:recyclerview-v7:21.0.0'
compile 'com.viewpagerindicator:library:2.4.1@aar'
compile project(':facebook')
}

它可以编译，但在设备上运行时出现以下异常

Caused by: java.lang.ClassNotFoundException: Didn't find class "android.view.RecyclerView" on path: DexPathList[[zip file "/data/app/xxxx.apk"],nativeLibraryDirectories=[/data/app-lib/xxxx, /vendor/lib, /system/lib]]

Answer 1

您的布局有问题。改变

<RecyclerView 
   ...

到

<android.support.v7.widget.RecyclerView
   ...

如果您以编程方式创建 RecyclerView - 请确保您有正确的导入:

import android.support.v7.widget.RecyclerView;
