Recyclerview是否可以在具有Jellybean的android设备上工作? [英] Would recyclerview work on an android device with Jellybean?

问题描述

要显示项目列表，我在我的应用程序中使用的是最新的RecyclerView. 我想知道它只能在具有Android 5.0的设备上运行还是在较低版本上运行?

TO display a list of items I am using the latest RecyclerView in my app. I want to know would it only work on devices having android 5.0 or would it on work on lower versions as well ?

推荐答案

是的，它向后兼容，前提是您包括了

Yes, it's backwards-compatible, assuming you include the support library for RecyclerView v7 in your application's build.gradle file:

请确保您已使用SDK Manager下载了Android支持资料库.

Make sure you have downloaded the Android Support Repository using the SDK Manager.

1. 为您的应用程序打开build.gradle文件.

添加支持 库功能项目标识符到依赖项部分，如下所示:

Add the support library feature project identifier to the dependencies section just like this:

dependencies {
     ...
     compile "com.android.support:recyclerview-v7:21.0.0.+" 
}

该版本的最低版本将降至Android 2.1(API级别7)，因此名称为v7

That one will work down as low as Android 2.1 (API level 7), hence the name v7
