将广告放入recyclerview中每5个项目？

Question

我对recyclerview有疑问，我想在我的recyclerview中放置广告（不是google的原生广告）。广告来自API。我想将这些广告放在我的Recyclerview中，其中包含来自API的新闻。

所以，我有两次来自api的回复，以进入recyclerview。以下是我的新闻回复和广告回复。

新闻回复api https://jsonblob.com/7ba93af8-6884-11e8-94d5-4b6d8b2939b5

广告回复api https://jsonblob.com/5010a591-6884-11e8-94d5-6505b8737ba5

我想在每5条新闻中展示我的广告，在我的回收者视图之间投放广告的最佳方式是什么？

[EDI 1] 这是我的适配器
