问题：

尝试从一个json对象中的两个json数组在recyclerview中填充数据时发生IndexOutOfBoundsException

李洋
2023-03-14

我从服务器获得一个Json对象，该Json对象包含两个Json数组。我知道如何将数据放入json数组中的recyclerview。但我不知道如何将两个json数组数据放入recyclerview。其中一个Json数组包含rep、name和name1。这里的name表示name1的id（codeID）。下一个数组包含customer（codeID）和coll（name和customer相同）。我使用两个不同的表生成json。我现在正在recyclerview中成功填充名称1。

我想要的是获取 name1 及其相应的 coll 值。例如，每行都需要表示 name1 和 name1 的 coll 值。某些 name1 没有 coll 值（null）。在这种情况下，coll 文本视图需要为空。有时两个数组的大小（长度）不相等。

这是我的Json。

请写入此条件，而不是从索引位置提取对象：

 if (dealerCollectionArrayList.size < position) {
        final DealerCollection model_two = dealerCollectionArrayList.get(position);
        holder.bind_two(model_two);

        if (dealerArrayList.get(position).getDealerId() == dealerCollectionArrayList.get(position).getDealerName()) {
            holder.dealerCol.setText(dealerCollectionArrayList.get(position).getDealerCollection());
        }
    }else {
         //Set not available or something
    }
