サーバーからJsonオブジェクトを取得していて、そのJsonオブジェクトに2つのJson配列が含まれていました。私はjson配列の中でrecyclerviewにデータを入れる方法を知っています。しかし、私は2つのjson配列データをrecyclerviewに入れる方法を知らない。 1つのJson配列には、rep、name、name1が含まれていました。 nameはname1のid（codeID）を意味します。次の配列にはcustomer（codeID）とcoll（名前と顧客は同じです）が含まれています。私は2つの異なるテーブルを使用してjsonを生成しています。私は、recyclerviewのname1を現在正常に入力しています。IndexOutOfBoundsException 1つのjsonオブジェクトの2つのjson配列からデータを取り込もうとしたとき
私が望むのは、name1とそれに対応するcoll値を取得することです。たとえば、各行はname1とname1のcoll値を表す必要があります。 name1の中にはcoll値（null）がありません。その場合、coll textviewは空である必要があります。場合によっては、2つの配列サイズ（長さ）が等しくないことがあります。
これは私のJsonです。

2番目の配列リスト項目をrecyclerviewの対応する名前に追加する方法を提案できますか？ –
はdealerCollectionArrayListオブジェクトサイズはdealerArrayListオブジェクトサイズと同じです...？ –
