I am trying to display multiple arraylists from a JSON object in a nested RecyclerView using Android kotlin. I have been able to successfully parse the JSON object and extract the arraylists, but I am having trouble displaying them in the nested RecyclerView.

Here is an example of the JSON object I am working with

Answer 1

For example my simple JSON multiple 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"
    }
]

}

you must declare multiple arraylists in your model class

For example MultipleResource model class - 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;

}
}

handle multiple json arraylist - example code (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 + "\n" + "Total :" + total + "\n" + "Total Pages :" + totalPages;

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

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

        }
    });

output
