我也在Google网上论坛和

I asked this question on Google Groups too and just got a reply from a guy named 'Vu Chau (Mobile Ads SDK Team)' via Google Mobile Ads SDK Developers.

他说:

在RecyclerView中为您的本地速成广告使用一个广告单元ID 实现很好.如果您检查我们的 NativeExpressRecyclerViewExample ，您可以看到我们也使用了

Using one ad unit ID for your native express ads in a RecyclerView implementation is fine. If you check our NativeExpressRecyclerViewExample, you can see we also use one ad unit ID.

哇！谢谢Vu Chau！

Whoa! Thanks Vu Chau!
