我正在尝试使用 Android kotlin 在嵌套的 RecyclerView 中显示来自 JSON 对象的多个数组列表。我已经能够成功解析 JSON 对象并提取数组列表，但我无法在嵌套的 RecyclerView 中显示它们。

这是我正在使用的 JSON 对象的示例

【问题讨论】：

标签： android json kotlin nestedrecyclerview

【解决方案1】：

例如我的简单JSON 多个 Arraylist

{
"page":1,
"per_page":3,
"total":12,
"total_pages":4,
"data": [
    {
        "id": 1,
        "name": "akila",
        "year": 2000,
        "pantone_value": "15-4020"
    },
    {
        "id": 2,
        "name": "prasanth",
        "year": 2001,
        "pantone_value": "17-2031"
    },
    {
        "id": 3,
        "name": "santhiya",
        "year": 2002,
        "pantone_value": "19-1664"
    }
]

}

你必须声明多个数组列表在你的模型类

例如 MultipleResource 模型类 - JAVA

public class MultipleResource {

@SerializedName("page")
public Integer page;
@SerializedName("per_page")
public Integer perPage;
@SerializedName("total")
public Integer total;
@SerializedName("total_pages")
public Integer totalPages;
@SerializedName("data")
public List<Datum> data = null;

public class Datum {

    @SerializedName("id")
    public Integer id;
    @SerializedName("name")
    public String name;
    @SerializedName("year")
    public Integer year;
    @SerializedName("pantone_value")
    public String pantoneValue;

}
}

处理多个 json arraylist - 示例代码 (JAVA)

   Call<MultipleResource> call = apiInterface.doGetListResources();
    call.enqueue(new Callback<MultipleResource>() {
        @Override
        public void onResponse(Call<MultipleResource> call, Response<MultipleResource> response) {
            Log.d("TAG", response.code()+"");
            String displayResponse = "";

            MultipleResource resource = response.body();
            Integer text = resource.page;
            Integer total = resource.total;
            Integer totalPages = resource.totalPages;
            List<MultipleResource.Datum> datumList = resource.data;

            displayResponse += "Page :" + text + "
" + "Total :" + total + "
" + "Total Pages :" + totalPages;

            for (MultipleResource.Datum datum : datumList){
                displayResponse += "
" + datum.id + "" + datum.name + datum.pantoneValue + datum.year ;
            }
            responseText.setText(displayResponse);
        }

        @Override
        public void onFailure(Call<MultipleResource> call, Throwable t) {

        }
    });

output
