I'am trying to parse data to a recyclerview, i had some problems about expecting JSONArray/JSONObject that i fixed with some help, but this moment I am a little bit lost in what to do in the Onresponse
, the original - generatePhonesList(response.body())
isnt working.
this is my json and i am trying to parse the data inside the array results[]
:
{
"success": true,
"metadata": {
"sort": "POPULARITY",
"total_products": 20,
"title": "Phones & Tablets",
"results": [
{
"sku": "1",
"name": "Samsung Galaxy S9",
"brand": "Samsung",
"max_saving_percentage": 30,
"price": 53996,
"special_price": 37990,
"image": "https://cdn2.gsmarena.com/vv/bigpic/samsung-galaxy-s9-.jpg",
"rating_average": 5
},
MainActivity (CALL and Recyclerview creation) :
GetPhoneDataService service = RetrofitInstance.getRetrofitInstance().create(GetPhoneDataService.class);
Call<APIReponse> call = service.getAllPhones();
call.enqueue(new Callback<APIReponse>() {
@Override
public void onResponse(Call<APIReponse> call, Response<APIReponse> response) {
generatePhonesList(response.body());
}
@Override
public void onFailure(Call<APIReponse> call, Throwable t) {
Log.e("eee" , "" + t.getMessage());
}
});
}
private void generatePhonesList(List<Result> phonesList){
recyclerView = findViewById(R.id.recyclerView);
adapter = new PhonesAdapter(phonesList,this);
RecyclerView.LayoutManager layoutManager = new LinearLayoutManager(MainActivity.this);
recyclerView.setLayoutManager(layoutManager);
recyclerView.setAdapter(adapter);
}
this is the POJO Class's created in jsonschema2pojo :
public class APIReponse {
@SerializedName("success")
@Expose
private Boolean success;
@SerializedName("metadata")
@Expose
private Metadata metadata;
public Boolean getSuccess() {
return success;
}
public void setSuccess(Boolean success) {
this.success = success;
}
public Metadata getMetadata() {
return metadata;
}
public void setMetadata(Metadata metadata) {
this.metadata = metadata;
}
}
2 class
public class MetaData {
@SerializedName("sort")
@Expose
private String sort;
@SerializedName("total_products")
@Expose
private Integer totalProducts;
@SerializedName("title")
@Expose
private String title;
@SerializedName("results")
@Expose
private List<Result> results = null;
public String getSort() {
return sort;
}
public void setSort(String sort) {
this.sort = sort;
}
public Integer getTotalProducts() {
return totalProducts;
}
public void setTotalProducts(Integer totalProducts) {
this.totalProducts = totalProducts;
}
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
public List<Result> getResults() {
return results;
}
public void setResults(List<Result> results) {
this.results = results;
}
}
3 class:
public class Result {
@SerializedName("sku")
@Expose
private String sku;
@SerializedName("name")
@Expose
private String name;
@SerializedName("brand")
@Expose
private String brand;
@SerializedName("max_saving_percentage")
@Expose
private Integer maxSavingPercentage;
@SerializedName("price")
@Expose
private Integer price;
@SerializedName("special_price")
@Expose
private Integer specialPrice;
@SerializedName("image")
@Expose
private String image;
@SerializedName("rating_average")
@Expose
private Integer ratingAverage;
public String getSku() {
return sku;
}
public void setSku(String sku) {
this.sku = sku;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getBrand() {
return brand;
}
public void setBrand(String brand) {
this.brand = brand;
}
public Integer getMaxSavingPercentage() {
return maxSavingPercentage;
}
public void setMaxSavingPercentage(Integer maxSavingPercentage) {
this.maxSavingPercentage = maxSavingPercentage;
}
public Integer getPrice() {
return price;
}
public void setPrice(Integer price) {
this.price = price;
}
public Integer getSpecialPrice() {
return specialPrice;
}
public void setSpecialPrice(Integer specialPrice) {
this.specialPrice = specialPrice;
}
public String getImage() {
return image;
}
public void setImage(String image) {
this.image = image;
}
public Integer getRatingAverage() {
return ratingAverage;
}
public void setRatingAverage(Integer ratingAverage) {
this.ratingAverage = ratingAverage;
}
}
If you pay close attention response.body()
will provide you with class APIResponse
. But you need is List<Result>
. To achieve this, try response.body().getMetadata().getResults()
This should give you the desired output.
You are passing the APIReponse
model to the generatePhonesList(List<Result> phonesList)
function. You need to pass only the list of results in this function.
Replace this:
generatePhonesList(response.body());
with:
generatePhonesList(response.body().getMetadata().getResults());
Here getMetadata() and getResults() are the getter functions of metadata model and List.
