void insert(List<StoreModel> storeModels);
#Query("DELETE FROM store")
void deleteAll();
#Query("SELECT * FROM store ORDER BY database_id ASC")
DataSource.Factory<Integer,StoreModel>getAllItems();
}

Set recyclerView.setAdapter(storeAdapter); outside of observer because each time data is observed it will set adapter. So, adapter is attached to recyclerView only once. Like
recyclerView.setAdapter(storeAdapter);
store_viewModel.pagedListLiveData.observe(this, new Observer<PagedList<StoreModel>>() {
#Override
public void onChanged(PagedList<StoreModel> storeModels) {
storeAdapter.submitList(storeModels);
//recyclerView.setAdapter(storeAdapter);
}
});
From the API you are not getting exactly the StoreModel as response. You are getting another object which is StoreModel is a child object. You have to create resposne object like below:
public class ResponseObject{
//#SerializedName("status")
//private int status;
#SerializedName("data")
private List<StoreModel> storeModelList;
//getters and setters goes here
}
And then your interface should be like below as you are expecting
ResponseObject here
public interface Api {
#GET("/get-products")
Call<ResponseObject> getAllProducts();
}

How to Show GridView Image In Android Fragments Using Json (categories and subcategories)

Those are categories and subcategories. There can be subcategory or not.
JsonCode to be used is as below.
categoryId is what will change to call subcategories.
E.g. If you want to see subcategories of cars
Json Code

I don't know how to add Json data into GridView.
Could you help me?

Go through this example to view images in grid,
Convert your jsonArray into an ArrayList by using,
ArrayList<Cars> carsList = new Gson().fromJson(jsonArrayYouHave.toString(),new TypeToken<List<Cars>>() {
}.getType());
Pass this Array to your Adapter.
Use this POJO,
public class Cars {
private String TitleAR;
private String HaveModel;
private String TitleEN;
private String Id;
private ArrayList<SubCategories> SubCategories;
private String Photo;
private String ProductCount;
//Todo please add getter/setters for class Cars variables here
public class SubCategories {
private String TitleAR;
private String HaveModel;
private String TitleEN;
private String Id;
private ArrayList<String> SubCategories;
private String Photo;
private String ProductCount;
//Todo please add getter/setters for class SubCategories variables here
}
I'll suggest to use Retrofit as it'll provide you parsed arraylist which is converted into Response POJO you have provided. You can find many examples for Retrofit.

Step 1
Add the following dependencies in your app level gradle file.Dependencies are for retrofit, gsonConvertor butterknife and glide.
implementation 'com.squareup.retrofit2:retrofit:2.1.0'
implementation 'com.google.code.gson:gson:2.6.2'
implementation 'com.squareup.retrofit2:converter-gson:2.1.0'
implementation('com.squareup.retrofit2:retrofit:2.1.0') {
// exclude Retrofit’s OkHttp dependency module and define your own module import
exclude module: 'okhttp'
}
implementation 'com.google.code.gson:gson:2.6.2'
implementation 'com.squareup.retrofit2:converter-gson:2.1.0'
implementation 'com.squareup.okhttp3:logging-interceptor:3.4.1'
implementation 'com.squareup.okhttp3:okhttp:3.4.1'
implementation 'com.android.support:design:28.0.0'
implementation 'com.android.support:recyclerview-v7:28.0.0'
implementation "com.jakewharton:butterknife:$BUTTER_KNIFE_VERSION"
annotationProcessor "com.jakewharton:butterknife-compiler:$BUTTER_KNIFE_VERSION"
implementation 'com.github.bumptech.glide:glide:4.8.0'
annotationProcessor 'com.github.bumptech.glide:compiler:4.8.0'
Step 2 Create a class by name ApiClient and paste the following code in this class
public class ApiClient {
private static Retrofit retrofit = null;
public static Retrofit getRetrofit() {
HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor();
interceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
OkHttpClient client = new OkHttpClient.Builder().addInterceptor(interceptor).build();
retrofit = new Retrofit.Builder()
.baseUrl("http://souq.hardtask.co")
.addConverterFactory(GsonConverterFactory.create())
.client(client)
.build();
return retrofit;
}
}
Step 3 Create a new Interface class by name APIInterface and paste the following code in this class
#GET("/app/app.asmx/GetCategories")
Call<List<Product>> getProducts(#QueryMap Map<String, String> params);
Step 4 Create POJO classes according to json response. We have two classes Products and their subcategory.So I am creating first class by name Product
public class Product {
#SerializedName("Id")
#Expose
private Integer id;
#SerializedName("TitleEN")
#Expose
private String titleEN;
#SerializedName("TitleAR")
#Expose
private String titleAR;
#SerializedName("Photo")
#Expose
private String photo;
#SerializedName("ProductCount")
#Expose
private String productCount;
#SerializedName("HaveModel")
#Expose
private String haveModel;
#SerializedName("SubCategories")
#Expose
private List<SubCategory> subCategories = null;
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getTitleEN() {
return titleEN;
}
public void setTitleEN(String titleEN) {
this.titleEN = titleEN;
}
public String getTitleAR() {
return titleAR;
}
public void setTitleAR(String titleAR) {
this.titleAR = titleAR;
}
public String getPhoto() {
return photo;
}
public void setPhoto(String photo) {
this.photo = photo;
}
public String getProductCount() {
return productCount;
}
public void setProductCount(String productCount) {
this.productCount = productCount;
}
public String getHaveModel() {
return haveModel;
}
public void setHaveModel(String haveModel) {
this.haveModel = haveModel;
}
public List<SubCategory> getSubCategories() {
return subCategories;
}
public void setSubCategories(List<SubCategory> subCategories) {
this.subCategories = subCategories;
}
}
And SubCategory
public class SubCategory {
#SerializedName("Id")
#Expose
private Integer id;
#SerializedName("TitleEN")
#Expose
private String titleEN;
#SerializedName("TitleAR")
#Expose
private String titleAR;
#SerializedName("Photo")
#Expose
private String photo;
#SerializedName("ProductCount")
#Expose
private String productCount;
#SerializedName("HaveModel")
#Expose
private String haveModel;
#SerializedName("SubCategories")
#Expose
private List<Object> subCategories = null;
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getTitleEN() {
return titleEN;
}
public void setTitleEN(String titleEN) {
this.titleEN = titleEN;
}
public String getTitleAR() {
return titleAR;
}
public void setTitleAR(String titleAR) {
this.titleAR = titleAR;
}
public String getPhoto() {
return photo;
}
public void setPhoto(String photo) {
this.photo = photo;
}
public String getProductCount() {
return productCount;
}
public void setProductCount(String productCount) {
this.productCount = productCount;
}
public String getHaveModel() {
return haveModel;
}
public void setHaveModel(String haveModel) {
this.haveModel = haveModel;
}
public List<Object> getSubCategories() {
return subCategories;
}
public void setSubCategories(List<Object> subCategories) {
this.subCategories = subCategories;
}
}
Step 5 now we need a view for recyclerview holder(in your case gridview layout). For that we need to create a new layout file inside layout folder. you can name it li_product_view
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<RelativeLayout
android:layout_width="200dp"
android:layout_height="200dp">
<ImageView
android:id="#+id/ImageView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:src="#mipmap/ic_launcher" />
<TextView
android:id="#+id/tv_title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignLeft="#id/ImageView"
android:layout_alignTop="#id/ImageView"
android:layout_alignRight="#id/ImageView"
android:layout_alignBottom="#id/ImageView"
android:text="#string/app_name"
android:gravity="bottom|right" />
</RelativeLayout>
</RelativeLayout>
Step 6 Now we need itemHolder to hold the view for that purpose we will create a new class by name ProductsItemHolderand will have the following code
public class ProductsItemHolder extends RecyclerView.ViewHolder {
#BindView(R.id.ImageView)
ImageView imageView;
#BindView(R.id.tv_title)
TextView textView;
public ProductsItemHolder(#NonNull View itemView) {
super(itemView);
ButterKnife.bind(this,itemView);
}
public void bindData(Product datum, int position, int size) {
Glide.with(itemView)
.asBitmap()
.load(datum.getPhoto())
.into(imageView);
textView.setText(datum.getTitleAR());
}
}
Step 7 Now we need adapter which contains the data to present inside recyclerview. Create a new class by name ProductsAdapter and paste the following code inside this class
public class ProductsAdapter extends RecyclerView.Adapter<RecyclerView.ViewHolder> {
private List<Product> mList;
#NonNull
#Override
public RecyclerView.ViewHolder onCreateViewHolder(#NonNull ViewGroup viewGroup, int i) {
View view = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.li_product_view, viewGroup, false);
return new ProductsItemHolder(view);
}
#Override
public void onBindViewHolder(#NonNull RecyclerView.ViewHolder viewHolder, int position) {
int size= mList.size();
((ProductsItemHolder) viewHolder).bindData(mList.get(position), position,size);
}
#Override
public int getItemCount() {
return mList.size();
}
public void setData(List<Product> userLists) {
this.mList = userLists;
notifyDataSetChanged();
}
}
Step 8 now inside the activity or fragment we need to get response from json and pass this response to recyclerview.
public class MainActivity extends AppCompatActivity {
APIInterface apiInterfacePages;
RecyclerView recyclerView;
List<MultipleResource.Datum> datumList= new ArrayList<>();
ProgressDialog dialog;
ProductsAdapter productsAdapter;
private List<Product> dataArrayList;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
apiInterfacePages= PageApiClient.getRetrofit().create(APIInterface.class);
recyclerView= findViewById(R.id.recyclerView);
productsAdapter= new ProductsAdapter();
StaggeredGridLayoutManager staggeredGridLayoutManager = new StaggeredGridLayoutManager(2, LinearLayoutManager.VERTICAL);
recyclerView.setLayoutManager(staggeredGridLayoutManager);
getData();
}
private void getData() {
dataArrayList = new ArrayList<>();
Map<String, String> params = new HashMap<String, String>();
params.put("categoryId", "0");
params.put("countryId", "1");
Call<List<Product>> call= apiInterfacePages.getProducts(params);
call.enqueue(new Callback<List<Product>>() {
#Override
public void onResponse(Call<List<Product>> call, Response<List<Product>> response) {
dataArrayList = response.body();
productsAdapter.setData(dataArrayList);
recyclerView.setAdapter(productsAdapter);
}
#Override
public void onFailure(Call<List<Product>> call, Throwable t) {
Log.i("Call response",t.getMessage());
}
});
}
}

Android Retrofit 2.1.0 Response.body() is null, status code is 404

I am trying to make a call to this api and am having difficulty as the response.body() is returning null.
http://demo.museum.vebrary.vn/api/stuff/getall
I want to get stuff name of list and show to my recyclerview.
My model:
public class SOAnswersResponse {
#SerializedName("StuffModels")
#Expose
private List<StuffModel> stuffModels = null;
public List<StuffModel> getStuffModels() {
return stuffModels;
}
public void setStuffModels(List<StuffModel> stuffModels) {
this.stuffModels = stuffModels;
}
and
public class StuffModel {
#SerializedName("STUFFID")
#Expose
private Integer sTUFFID;
#SerializedName("STUFFCODE")
#Expose
private String sTUFFCODE;
#SerializedName("STUFFNAME")
#Expose
private String sTUFFNAME;
#SerializedName("STUFFNOTE")
#Expose
private String sTUFFNOTE;
#SerializedName("STUFFORDER")
#Expose
private Integer sTUFFORDER;
#SerializedName("CUSTOMERID")
#Expose
private String cUSTOMERID;
#SerializedName("EXHIBITS")
#Expose
private List<Object> eXHIBITS = null;
Json response

{
"STUFFID":2,
"STUFFCODE":"Gi",
"STUFFNAME":"Giấy",
"STUFFNOTE":"",
"STUFFORDER":2,

},
ApiUtils Class
public class ApiUtils {
private ApiUtils() {
}
public static final String BASE_URL = "http://demo.museum.vebrary.vn/api/";
public static SOService getSOService() {
return RetrofitClient.getClient(BASE_URL).create(SOService.class);
}
}
Service interface
public interface SOService {
#GET("/stuff/getall")
Call<SOAnswersResponse> getAnswers();
}
RetrofitClient Class
public class RetrofitClient {
private static Retrofit retrofit = null;
public static Retrofit getClient(String baseUrl) {
if (retrofit==null) {
retrofit = new Retrofit.Builder()
.baseUrl(baseUrl)
.addConverterFactory(GsonConverterFactory.create())
.build();
}
return retrofit;
}
}
My RecyclerView adapter
public class CategogyNameRecyclerViewAdapter extends RecyclerView.Adapter<CategogyNameRecyclerViewAdapter.ViewHolder> {
private List<StuffModel> mItems;
private Context mContext;
private PostItemListener mItemListener;
public class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener{
public TextView titleTv;
PostItemListener mItemListener;
public ViewHolder(View itemView, PostItemListener postItemListener) {
super(itemView);
titleTv = itemView.findViewById(R.id.tvListMenuCategogy);
this.mItemListener = postItemListener;
itemView.setOnClickListener(this);
}
#Override
public void onClick(View view) {
StuffModel item = getItem(getAdapterPosition());
this.mItemListener.onPostClick(item.getSTUFFID());
notifyDataSetChanged();
}
}
public CategogyNameRecyclerViewAdapter(Context context, List<StuffModel> posts, PostItemListener itemListener) {
mItems = posts;
mContext = context;
mItemListener = itemListener;
}
#Override
public CategogyNameRecyclerViewAdapter.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
Context context = parent.getContext();
LayoutInflater inflater = LayoutInflater.from(context);
View postView = inflater.inflate(R.layout.item_list_text, parent, false);
ViewHolder viewHolder = new ViewHolder(postView, this.mItemListener);
return viewHolder;
}
#Override
public void onBindViewHolder(CategogyNameRecyclerViewAdapter.ViewHolder holder, int position) {
StuffModel item = mItems.get(position);
TextView textView = holder.titleTv;
textView.setText(item.getSTUFFNAME());
}
#Override
public int getItemCount() {
return mItems.size();
}
public void updateAnswers(List<StuffModel> items) {
mItems = items;
notifyDataSetChanged();
}
private StuffModel getItem(int adapterPosition) {
return mItems.get(adapterPosition);
}
public interface PostItemListener {
void onPostClick(long id);
}
}
And my main activity
public class Testttt extends AppCompatActivity {
private CategogyNameRecyclerViewAdapter mAdapter;
private RecyclerView mRecyclerView;
private SOService mService;
#Override
protected void onCreate (Bundle savedInstanceState) {
super.onCreate( savedInstanceState );
setContentView(R.layout.test );
mService = ApiUtils.getSOService();
mRecyclerView = (RecyclerView) findViewById(R.id.rcvCategogyNameMenuTest);
mAdapter = new CategogyNameRecyclerViewAdapter(this, new ArrayList<StuffModel>(0), new CategogyNameRecyclerViewAdapter.PostItemListener() {
#Override
public void onPostClick(long id) {
Toast.makeText(Testttt.this, "Post id is" + id, Toast.LENGTH_SHORT).show();
}
});
RecyclerView.LayoutManager layoutManager = new LinearLayoutManager(this);
mRecyclerView.setLayoutManager(layoutManager);
mRecyclerView.setAdapter(mAdapter);
mRecyclerView.setHasFixedSize(true);
RecyclerView.ItemDecoration itemDecoration = new DividerItemDecoration(this, DividerItemDecoration.VERTICAL_LIST);
mRecyclerView.addItemDecoration(itemDecoration);
loadAnswers();
}
public void loadAnswers() {
mService.getAnswers().enqueue(new Callback<SOAnswersResponse>() {
#Override
public void onResponse(Call<SOAnswersResponse> call, Response<SOAnswersResponse> response) {
Toast.makeText(Testttt.this, "333333333333333333"+response.body(), Toast.LENGTH_SHORT).show();
if(response.isSuccessful()) {
mAdapter.updateAnswers(response.body().getStuffModels());
Log.d("AnswersPresenter", "posts loaded from API");
}else {
int statusCode = response.code();
}
}
#Override
public void onFailure(Call<SOAnswersResponse> call, Throwable t) {
showErrorMessage();
Log.d("AnswersPresenter", "error loading from API");
}
});
}
public void showErrorMessage() {
Toast.makeText(this, "Error loading posts", Toast.LENGTH_SHORT).show();
}
}

The first thing that came in my mind:
Your
public static final String BASE_URL = "http://demo.museum.vebrary.vn/api/";
has a "/" at the the end and your
#GET("/stuff/getall")
Call<SOAnswersResponse> getAnswers();
starts with a "/". So there is a double backslash in the url that might leads to the 404 code. Does this solve the problem?
When i call your URL i receive XML. Maybe the API is not configured correctly?

Change your Service interface
public interface SOService {
#GET("stuff/getall")
Call<SOAnswersResponse> getAnswers();
}
it occurred because you have use start with backslash it already added in your base url

Android Studio Recyclerview use Retrofit

please help me..
i have 10 policy data on my PHP to show on recyclerview android studio using retrofit..but, when i run my emulator, the emulator just show 1 data..my plan just show PolicyNo..when i running emulator and check my log, they've said : my Number Policy Received: 10
sorry for my bad english :(
here is my policyActivity :
public class PolicyActivity extends AppCompatActivity {
private static final String TAG = PolicyActivity.class.getSimpleName();
private String policyno;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_policy);
final RecyclerView recyclerView = (RecyclerView) findViewById(R.id.policy_recycler_view);
recyclerView.setLayoutManager(new LinearLayoutManager(this));
ApiEndPoint apiEndPoint =
ApiClient.getClient(this).create(ApiEndPoint.class);
Call<PolicyStatus> call = apiEndPoint.getPolicyNo(policyno);
call.enqueue(new Callback<PolicyStatus>() {
#Override
public void onResponse(Call<PolicyStatus> call, Response<PolicyStatus> response) {
List<PolicyNo> policyNo = response.body().getPolicyNo();
Log.d(TAG, "Number Policy Received: " + policyNo.size());
recyclerView.setAdapter(new PolicyAdapter(policyNo, R.layout.list_item_policy, getApplicationContext()));
}
#Override
public void onFailure (Call <PolicyStatus> call, Throwable t){
Log.e(TAG, t.toString());
}
});
}
}
and this is my policyadapter:
public class PolicyAdapter extends RecyclerView.Adapter<PolicyAdapter.PolicyViewHolder> {
private List<PolicyNo> policyNo;
private int rowLayout;
private Context context;
public static class PolicyViewHolder extends RecyclerView.ViewHolder{
LinearLayout policyLayout;
TextView nomorpolis;
public PolicyViewHolder (View v){
super(v);
policyLayout = (LinearLayout) v.findViewById(R.id.policy_layout);
nomorpolis = (TextView)v.findViewById(R.id.nomorpolis);
}
}
public PolicyAdapter (List<PolicyNo>policyNo, int rowLayout, Context context){
this.policyNo = policyNo;
this.context = context;
this.rowLayout = rowLayout;
}
#Override
public PolicyAdapter.PolicyViewHolder onCreateViewHolder(ViewGroup parent, int viewType){
View view= LayoutInflater.from(parent.getContext()).inflate(rowLayout, parent, false);
return new PolicyViewHolder(view);
}
#Override
public void onBindViewHolder (PolicyViewHolder holder, final int position){
holder.nomorpolis.setText(policyNo.get(position).getPolicyNo());
}
#Override
public int getItemCount() {return policyNo.size();}
}
PolicyStatus :
public class PolicyStatus {
#SerializedName("success")
#Expose
private Boolean success;
#SerializedName("PolicyNo")
#Expose
private List<PolicyNo> policyNo = null;
public Boolean getSuccess() {
return success;
}
public void setSuccess(Boolean success) {
this.success = success;
}
public List<PolicyNo> getPolicyNo() {
return policyNo;
}
public void setPolicyNo(List<PolicyNo> policyNo) {
this.policyNo = policyNo;
}
PolicyNo :
public class PolicyNo {
#SerializedName("ANO")
#Expose
private Integer aNO;
#SerializedName("PolicyNo")
#Expose
private String policyNo;
#SerializedName("ADate")
#Expose
private ADate aDate;
#SerializedName("ADATE")
#Expose
private String aDATE;
public Integer getANO() {
return aNO;
}
public void setANO(Integer aNO) {
this.aNO = aNO;
}
public String getPolicyNo() {
return policyNo;
}
public void setPolicyNo(String policyNo) {
this.policyNo = policyNo;
}
public ADate getADate() {
return aDate;
}
public void setADate(ADate aDate) {
this.aDate = aDate;
}
public String getADATE() {
return aDATE;
}
public void setADATE(String aDATE) {
this.aDATE = aDATE;
}
public PolicyNo (String policyNo){
this.policyNo = policyNo;
}
}
api endpoint :
#GET ("policy.php")
Call<PolicyStatus> getPolicyNo (#Query("PolicyNo") String policyNo);

I think you have given list_item_policy to match_parent. as you are saying you are getting 10 size in log. then this can be only reason. may be you will find items on scroll. So just change this to wrap_content.
Also check your recyclerView getting full height check in the preview.

Code looks fine except one thing which I noticed :-
Do this :-
LinearLayoutManager layoutManager
= new LinearLayoutManager(this, LinearLayoutManager.VERTICAL, false);
myList.setLayoutManager(layoutManager);
instead of :-
recyclerView.setLayoutManager(new LinearLayoutManager(this));
