私のアプリケーション（RecyclerView）にサーバーからデータをロードして、このジョブでアプリケーションが起動すると10個の投稿が表示され、recyclerViewが別の投稿を表示します。RecyclerViewにレイアウトを表示する方法
私は以下のコードを書いていますが、他の10個の投稿を取得すると、が表示されません読み込みレイアウト！私は他の10の記事を得るとき、最初にを表示するのレイアウトを表示し、次に他を表示する10 投稿！
のために、私はRetrofit v2を使用し、カスタムのためにrecyclerViewためEndless methosが、私はこのクラスを使用してインターネットに接続：EndLess Class
My活動コード：

他の10個の投稿を受け取ったら、レイアウトを表示する方法を教えてください。
または別のトリックの底にこのレイアウトを追加することですあなたのrecyclerは関連するXMLで表示され、リストの最後に来ると可視/不可視になります – MehDi
私にコードを送ることができますか？私は素人です、あなたは私にコードを送ることができますか？ –
申し訳ありません私は最近忙しくて2つのプロジェクトに取り組んでいますが、おそらく次の週にお手伝いできます:) – MehDi
