How to create a retrofit2 array in android studio?

How to create a retrofit2 array in android studio? - java

I took this information out of a JSON and initialized it, but I don't understand how I can get the data out of the form to pass them to the cardView afterward. Or is there an easier way?
MainActivity
public class MainActivity extends AppCompatActivity {
Context context;
Example example;
Response responses;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
RecyclerView rv = (RecyclerView)findViewById(R.id.cartView);
LinearLayoutManager llm = new LinearLayoutManager(context);
Retrofit retrofit = new Retrofit.Builder()
.baseUrl("Secret Url") // For some reason I cannot show the url
.addConverterFactory(GsonConverterFactory.create())
.build();
Api api = retrofit.create(Api.class);
ArrayList arrayList = new ArrayList();
Call<Example> call = api.getRespon();
call.enqueue(new Callback<Example>() {
#Override
public void onResponse(Call<Example> call, Response<Example> response) {
if(response.code() != 200){
Toast.makeText(MainActivity.this, "Connect",Toast.LENGTH_SHORT).show();
return;
}
Example examples = response.body();
for(int i=0; i<examples.getResponse().size(); i++){
String f_name = response.body().getResponse().iterator().next().getfName();
String l_name = response.body().getResponse().iterator().next().getlName();
String birthday = response.body().getResponse().iterator().next().getBirthday();
String SpecName = response.body().getResponse().iterator().next().getSpecialty()
.iterator().next().getName();
int SpecId = response.body().getResponse().iterator().next().getSpecialty()
.iterator().next().getSpecialtyId();
}
}
#Override
public void onFailure(Call<Example> call, Throwable t) {
Toast.makeText(MainActivity.this, "Fail",Toast.LENGTH_SHORT).show();
}
});
}
}
At the moment I have not finished the class because I can not specify the data that have been implemented
PersonaAdapter
public class PersonAdapter extends RecyclerView.Adapter<PersonAdapter.PersonViewHolder> {
Context context;
Example example;
MainActivity mainActivity;
public static class PersonViewHolder extends RecyclerView.ViewHolder{
CardView cv;
TextView l_name, f_name, birthday, SpecName, Age;
ImageView avatar;
public PersonViewHolder(View itemView) {
super(itemView);
cv = itemView.findViewById(R.id.cartView);
l_name = itemView.findViewById(R.id.textLName);
f_name = itemView.findViewById(R.id.textFName);
birthday = itemView.findViewById(R.id.textBirthday);
SpecName = itemView.findViewById(R.id.textSpecName);
Age = itemView.findViewById(R.id.textAge);
}
}
// иницилизация
#Override
public PersonViewHolder onCreateViewHolder(ViewGroup viewGroup, int i) {
View v = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.item_layout,viewGroup,false);
PersonViewHolder phv = new PersonViewHolder(v);
return phv;
}
#Override
public void onBindViewHolder(PersonViewHolder personViewHolder, int i) {
//***
}
#Override
public int getItemCount() {
return example.getResponse().size();
}
#Override
public void onAttachedToRecyclerView(RecyclerView recyclerView) {
super.onAttachedToRecyclerView(recyclerView);
}
}
Handler itself
Response
public class Response {
#SerializedName("f_name")
#Expose
private String fName;
#SerializedName("l_name")
#Expose
private String lName;
#SerializedName("birthday")
#Expose
private String birthday;
#SerializedName("avatr_url")
#Expose
private String avatrUrl;
#SerializedName("specialty")

private List<Specialty> specialty = null;
public String getfName() {
return fName;
}
public void setfName(String fName) {
this.fName = fName;
}
public Response withfName(String fName) {
this.fName = fName;
return this;
}
public String getlName() {
return lName;
}
public void setlName(String lName) {
this.lName = lName;
}
public Response withlName(String lName) {
this.lName = lName;
return this;
}
public String getBirthday() {
return birthday;
}
public void setBirthday(String birthday) {
this.birthday = birthday;
}
public Response withBirthday(String birthday) {
this.birthday = birthday;
return this;
}
public String getAvatrUrl() {
return avatrUrl;
}
public void setAvatrUrl(String avatrUrl) {
this.avatrUrl = avatrUrl;
}
public Response withAvatrUrl(String avatrUrl) {
this.avatrUrl = avatrUrl;
return this;
}
public List<Specialty> getSpecialty() {
return specialty;
}
public void setSpecialty(List<Specialty> specialty) {
this.specialty = specialty;
}
public Response withSpecialty(List<Specialty> specialty) {
this.specialty = specialty;
return this;
}
}
Specialty
public class Specialty {
#SerializedName("specialty_id")
#Expose
private Integer specialtyId;
#SerializedName("name")
#Expose
private String name;
public Integer getSpecialtyId() {
return specialtyId;
}
public void setSpecialtyId(Integer specialtyId) {
this.specialtyId = specialtyId;
}
public Specialty withSpecialtyId(Integer specialtyId) {
this.specialtyId = specialtyId;
return this;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public Specialty withName(String name) {
this.name = name;
return this;
}
}

I solved the problem by creating a list and putting the data into an array
List<Worker> workerList = new ArrayList<>();
for(int i = 0; i < examples.getResponse().size(); i++){
String f_name = response.body().getResponse().get(i).getfName();
String l_name = response.body().getResponse().get(i).getlName();
String birthday = response.body().getResponse().get(i).getBirthday();
String SpecName = response.body().getResponse().get(i).getSpecialty()
.iterator().next().getName();
String SpecId = response.body().getResponse().iterator().next().getSpecialty()
.iterator().next().getSpecialtyId().toString();
String AvatarUrl = response.body().getResponse().get(i).getAvatrUrl();
workerList.add(new Worker(f_name, l_name, birthday, SpecName, SpecId, AvatarUrl));
In Worker has a constructor and getter

ListView is not showing all JSON data using Retrofit

I'm trying to get all the JSON result into my listview. I have successfully retrieved the data but it keeps only shows one data (example if JNE, only showing OKE result). I'm using Retrofit. Below is the example JSON data from the documentation that I want to show all in my listview. Please help me why it is not showing all the result. Thank you.

What am i doing wrong any help will appreciated.

Change your pojo class with this
package com.example;
import java.util.List;
import com.google.gson.annotations.Expose;
import com.google.gson.annotations.SerializedName;
public class Example {
#SerializedName("Message")
#Expose
private List<Message> message = null;
public List<Message> getMessage() {
return message;
}
public void setMessage(List<Message> message) {
this.message = message;
}
}
package com.example;
import com.google.gson.annotations.Expose;
import com.google.gson.annotations.SerializedName;
public class Message {
#SerializedName("Emp_Id")
#Expose
private Integer empId;
#SerializedName("Emp_First_Name")

private String empEmail;
#SerializedName("Emp_Address")
#Expose
private String empAddress;
#SerializedName("Emp_Phone_No")
#Expose

#Expose
private String empPhoto;
#SerializedName("Is_Resign")
#Expose
private Integer isResign;
#SerializedName("Joining_Date")
#Expose

#SerializedName("Resign_Date")
#Expose
private String resignDate;
#SerializedName("sms_status")
#Expose
private Integer smsStatus;
public Integer getEmpId() {
return empId;
}
public void setEmpId(Integer empId) {
this.empId = empId;
}
public String getEmpFirstName() {
return empFirstName;
}
public void setEmpFirstName(String empFirstName) {
this.empFirstName = empFirstName;
}
public String getEmpLastName() {
return empLastName;
}
public void setEmpLastName(String empLastName) {
this.empLastName = empLastName;
}
public String getEmpEmail() {
return empEmail;
}
public void setEmpEmail(String empEmail) {
this.empEmail = empEmail;
}
public String getEmpAddress() {
return empAddress;
}
public void setEmpAddress(String empAddress) {
this.empAddress = empAddress;
}
public String getEmpPhoneNo() {
return empPhoneNo;
}
public void setEmpPhoneNo(String empPhoneNo) {
this.empPhoneNo = empPhoneNo;
}
public String getEmpPassword() {
return empPassword;
}
public void setEmpPassword(String empPassword) {
this.empPassword = empPassword;
}
public String getEmpPhoto() {
return empPhoto;
}
public void setEmpPhoto(String empPhoto) {
this.empPhoto = empPhoto;
}
public Integer getIsResign() {
return isResign;
}
public void setIsResign(Integer isResign) {
this.isResign = isResign;
}
public String getJoiningDate() {
return joiningDate;
}
public void setJoiningDate(String joiningDate) {
this.joiningDate = joiningDate;
}
public String getResignDate() {
return resignDate;
}
public void setResignDate(String resignDate) {
this.resignDate = resignDate;
}
public Integer getSmsStatus() {
return smsStatus;
}
public void setSmsStatus(Integer smsStatus) {
this.smsStatus = smsStatus;
}
}
than change your code with this
Call<Example> call = service.Bind_Employee_Details_Based_On_Id(emailtoken);
call.enqueue(new Callback<Example>() {
#Override
public void onResponse(Call<Example> call, Response<Result> response) {
//.getMessage is POJO method to listen for final json output
List<Example> listResponse =response.body().getMessage();
String fname=listResponse.get(0).getEmpFirstName();
String lname=listResponse.get(0).getEmpLastName();
String email=listResponse.get(0).getEmpEmail();
String address=listResponse.get(0).getEmpAddress();
String joindt=listResponse.get(0).getJoiningDate();
etfname.setText(fname);
etlname.setText(lname);
etemail.setText(email);
etaddress.setText(address);
etjoindt.setText(joindt);
progressDialog.dismiss();
}

Check your Result class. Message is Array, not a String.
To generate Object from Json, go to http://pojo.sodhanalibrary.com/ and paste your Json.

make this pojo class like ..
public class MessageItem{
#SerializedName("Emp_Id")
private int empId;
#SerializedName("Emp_Email")
private String empEmail;
#SerializedName("Emp_First_Name")
private String empFirstName;
#SerializedName("Emp_Address")
private String empAddress;
#SerializedName("Joining_Date")
private String joiningDate;
#SerializedName("Is_Resign")
private int isResign;
#SerializedName("Emp_Last_Name")
private String empLastName;
#SerializedName("Emp_Photo")
private String empPhoto;
#SerializedName("Resign_Date")
private String resignDate;
#SerializedName("Emp_Phone_No")
private String empPhoneNo;
#SerializedName("Emp_Password")
private String empPassword;
#SerializedName("sms_status")
private int smsStatus;
public void setEmpId(int empId){
this.empId = empId;
}
public int getEmpId(){
return empId;
}
public void setEmpEmail(String empEmail){
this.empEmail = empEmail;
}
public String getEmpEmail(){
return empEmail;
}
public void setEmpFirstName(String empFirstName){
this.empFirstName = empFirstName;
}
public String getEmpFirstName(){
return empFirstName;
}
public void setEmpAddress(String empAddress){
this.empAddress = empAddress;
}
public String getEmpAddress(){
return empAddress;
}
public void setJoiningDate(String joiningDate){
this.joiningDate = joiningDate;
}
public String getJoiningDate(){
return joiningDate;
}
public void setIsResign(int isResign){
this.isResign = isResign;
}
public int getIsResign(){
return isResign;
}
public void setEmpLastName(String empLastName){
this.empLastName = empLastName;
}
public String getEmpLastName(){
return empLastName;
}
public void setEmpPhoto(String empPhoto){
this.empPhoto = empPhoto;
}
public String getEmpPhoto(){
return empPhoto;
}
public void setResignDate(String resignDate){
this.resignDate = resignDate;
}
public String getResignDate(){
return resignDate;
}
public void setEmpPhoneNo(String empPhoneNo){
this.empPhoneNo = empPhoneNo;
}
public String getEmpPhoneNo(){
return empPhoneNo;
}
public void setEmpPassword(String empPassword){
this.empPassword = empPassword;
}
public String getEmpPassword(){
return empPassword;
}
public void setSmsStatus(int smsStatus){
this.smsStatus = smsStatus;
}
public int getSmsStatus(){
return smsStatus;
}
}
public class ResponseData {
#SerializedName("Message")
private List<MessageItem> message;
public void setMessage(List<MessageItem> message){
this.message = message;
}
public List<MessageItem> getMessage(){
return message;
}
}
after that ..
Call<ResponseData>
when you getting response like
call.enqueue(new Callback<ResponseData>() {
#Override
public void onResponse(Call<ResponseData> call, Response<ResponseData> response) {
//.getMessage is POJO method to listen for final json output
if (response.isSuccessful() && response!=null && response.body()!=null){
List<MessageItem> message=response.body().getMessage();
if (message!=null && !message.isEmpty()){
for(MessageItem messageItem:message){
etfname.setText(messageItem.getEmpFirstName());
etlname.setText(messageItem.getEmpLastName());
//same for others
}
}
}
}
#Override
public void onFailure(Call<Result> call, Throwable t) {
progressDialog.dismiss();
Toast.makeText(getActivity(), t.getMessage(), Toast.LENGTH_LONG).show();
}
});

How to pass a class with an abstract class type as parameter in parcelable android studio java

I am trying to pass this class as a parcelable in android.
public class Outfit implements Parcelable {
private List<Item> itemList;
private String mName;
private String mImageUrl;
public Outfit() {}
public Outfit(String mName, String mImageUrl) {
this.mName = mName;
this.mImageUrl = mImageUrl;
}
protected Outfit(Parcel in) {
itemList = in.createTypedArrayList(Item.CREATOR);
mName = in.readString();
mImageUrl = in.readString();
}
public static final Creator<Outfit> CREATOR = new Creator<Outfit>() {
#Override
public Outfit createFromParcel(Parcel in) {
return new Outfit(in);
}
#Override
public Outfit[] newArray(int size) {
return new Outfit[size];
}
};
public String getmName() {
return mName;
}
public String getmImageUrl() {
return mImageUrl;
}
#Override
public String toString() {
return mName;
}
#Override
public int describeContents() {
return 0;
}
#Override
public void writeToParcel(Parcel parcel, int i) {
parcel.writeTypedList(itemList);
parcel.writeString(mName);
parcel.writeString(mImageUrl);
}
}
the problem is that Item is abstract and itemList = in.creatTypedArrayList(Item.CREATOR) because Item does not have a CREATOR . Only its subclasses have this implementation.
Item.java
public abstract class Item implements Parcelable {
private String mName;
private String mColor;
private String mImageUrl;
private List<TagHolder> tags = new ArrayList<>();
private String mKey;
public Item(){
}
public Item(String mName, String mColor, String mImageUrl) {
this.mName = mName;
this.mColor = mColor;
this.mImageUrl = mImageUrl;
}
protected Item(Parcel in) {
mName = in.readString();
mColor = in.readString();
mImageUrl = in.readString();
tags = in.createTypedArrayList(TagHolder.CREATOR);
mKey = in.readString();
}
#Override
public void writeToParcel(Parcel dest, int flags) {
dest.writeString(mName);
dest.writeString(mColor);
dest.writeString(mImageUrl);
dest.writeTypedList(tags);
dest.writeString(mKey);
}
#Override
public int describeContents() {
return 0;
}
public void setmName(String mName) {
this.mName = mName;
}
public void setmImageUrl(String mImageUrl) {
this.mImageUrl = mImageUrl;
}
public List<TagHolder> getTags() {
return tags;
}
public String getmColor() {
return mColor;
}
public String getmImageUrl() {
return mImageUrl;
}
public void setmColor(String mColor) {
this.mColor = mColor;
}
public String getmName() {
return mName;
}
public void setTags(List<TagHolder> tags) {
this.tags = tags;
}
#Exclude // dont need this in our firebase database
public String getKey() {
return mKey;
}
#Exclude
public void setMkey(String key) {
mKey = key;
}
public abstract String getCategory();
}
I am able to parce a List as a parcelable array when I call put extra. But when I try to do so for outfit it gives error . Is there any way to pass Outfit as a parcelable?

Do you try using another method for the list?
#Override
public void writeToParcel(Parcel parcel, int i) {
parcel.writeList(itemList);
parcel.writeString(mName);
parcel.writeString(mImageUrl);
}
protected Outfit(Parcel in) {
in.readList(itemList, Item.class.getClassLoader());
mName = in.readString();
mImageUrl = in.readString();
}

Issue with ArrayList from JSON using Retrofit and populating RecyclerView

I’ve been trying to get recycler view working with retrofit. I seem to be pulling in the JSON fine from within getRecipes() method, and my logs are showing me that the some data is there.
However, when I call my getRecipes() method from onCreate(), something seems to be going wrong. When I check to see if my recipeList array contains my JSON results within onCreate, it is telling me it is empty. Why is it doing this if my logs within my getRecipes() method are showing me that data is there...?
Not sure if it is an issue with my recycler view or what I am doing with retrofit, or something else. Been trying for days to figure out, so any advice would be greatly appreciated.

this will be empty always because this line will execute before getting the response from a server.
if(recipeList.isEmpty()){
Log.d(LOG_TAG, "Is empty");
}else {
Log.d(LOG_TAG, "Is not empty");
}
Better call this after this line recipeList = response.body();
SimpleItemRecyclerViewAdapter simpleItemRecyclerViewAdapter = new SimpleItemRecyclerViewAdapter(recipeList);
recyclerView.setAdapter(simpleItemRecyclerViewAdapter);
if (findViewById(R.id.item_detail_container) != null) {
mTwoPane = true;
}

it is because you are sending the recipelist into the adapter before even it is populated , after you are sending the recipelist into the adapter which is empty you are populating your recipelist from getRecipes method, you might be wondering you have declared the getRecipes method before even you are assigning the recipelist to adapter so how come it is empty, yea but the fact is your getRecipes work on background thread so even before your recipelist gets populated your adapter assignment takes place on the main thread so you are basically assigning the empty list, one thing you can do is notify when the adapter when the data changes or when the the recipelist is filled with data that is from within the getRecipe method.
when you assign the recipelist = response.body right after this you can notify the adapter
or move this two lines
SimpleItemRecyclerViewAdapter simpleItemRecyclerViewAdapter = new SimpleItemRecyclerViewAdapter(recipeList);
recyclerView.setAdapter(simpleItemRecyclerViewAdapter);
right after the
recipelist = response.body;
in getRecipes method

Try create the Constructor with all atributes from your Recipe.class
Like:
public Ingredients(String measure, String ingredients, String quantity ){
this.measure = measure;
this.ingredients = ingredients;
this.quantity = quantity
}
Do same in all class where make up your object of list.
