`Please help me, I am using retrofit2 library and Pinview and mobile number to authenticate users but as soon as I finish keying in pin, the app listens to pin key in.
Here is how I have declared base url and method that takes two parameters to be queried
String BASE_URL="http://192.168.0.19:2000/";
#GET("api/userprofile")
Call<Fetchnumber> getNumbers(#Query("phone" ) String phone, #Query("Password") String Password);
Here is the error I get in Logcat
java.lang.NullPointerException: Attempt to invoke virtual method 'java.lang.String e.uzer.msacco.Fetchnumber.getPassword()' on a null object reference
at e.uzer.msacco.UserLogin$1$1.onDataEntered(UserLogin.java:49)

at android.widget.TextView.handleTextChanged(TextView.java:8385)
at android.widget.TextView$ChangeWatcher.onTextChanged(TextView.java:10531)
Here is The retrofit library that shows how i have passed two parameters to the method getnumbers
Retrofit retrofit = new Retrofit.Builder().baseUrl(Api.BASE_URL).addConverterFactory(GsonConverterFactory.create()).build();
Api api = retrofit.create(Api.class);
Call<Fetchnumber> call = api.getNumbers(phonenumbersubmission.phone_number.getText().toString(),pinview.getValue().toString().trim());
call.enqueue(new Callback<Fetchnumber>() {
Here is how i have handled Onresponse
public void onResponse(Call<Fetchnumber> call, final Response<Fetchnumber> response) {
pinview.setPinViewEventListener(new Pinview.PinViewEventListener() {
#Override
public void onDataEntered(Pinview pinview, boolean b) {
if ((response.body().getPassword().equals(pinview.getValue().toString())&&( response.body().getPhonenumber().toString().equals(phonenumbersubmission.phone_number.toString())))) {

Intent intent = new Intent(UserLogin.this, enrollment.class);
startActivity(intent);
} else {
Toast.makeText(UserLogin.this, "Wrong PIN", Toast.LENGTH_LONG).show();
Where getPassword and getPhonenumber() are from POJO class.
Any help will be much appreciated,
Thank you in andvance.

I am trying to experiment and learn BuilderPattern,reading from json file at the same time. My goal is to create object using the data I get from the json file. This is how the json file looks like:
[{
"firstName": "Git",
"lastName": "Hub",
"website": "howtodoinjava.com"
},
{
"firstName": "Brian",
"lastName": "Schultz"
}
]
Class1: Employee Class
public class Employee {
private String firstName; // required
private String lastName; // required
private String website; // optional
//Only has setters
public void setFirstName(String firstName) {
this.firstName = firstName;
}
public void setLastName(String lastName) {
this.lastName = lastName;
}
public void setWebsite(String website) {
this.website = website;
}
//no public constructor. So the only way to get a Employee object is through the EmployeeBuilder class.
private Employee(EmployeeBuilder builder) {
this.firstName = firstName;
this.lastName = lastName;
this.website = website;
}
public static class EmployeeBuilder {
private String firstName; // required
private String lastName; // required
private String website; // optional
public EmployeeBuilder() throws IOException {
}
public EmployeeBuilder requiredFirstName(String firstName) {
this.firstName = firstName;
return this;
}
public EmployeeBuilder requiredLastName(String lastName) {
this.lastName = lastName;
return this;
}
public EmployeeBuilder optionalWebsite(String website) {
this.website = website;
return this;
}
//Return the finally constructed User object
public Employee build() {
Employee emp = new Employee(this);
return emp;
}
}
}
Class2: User Class
public class User {
String firstName;
String lastName;
String website;
//Using Getters to get values from Json
public String getFirstName() {
return firstName;
}
public String getLastName() {
return lastName;
}
public String getWebsite() {
return website;
}
}
3 Main class
public class Main {
public static void main(String[] args) throws IOException {
ObjectMapper object = new ObjectMapper();
User[] user = object.readValue(new File("C:\\MyTemp\\jackson.json"), User[].class);
//Employee employee= new Employee.EmployeeBuilder().requiredFirstName(person.getFirstName()).requiredLastName(person.getLastName()).optionalWebsite(person.getWebsite()).build();
List<User> emp1 = object.readValue("C:\\MyTemp\\jackson.json", new TypeReference<List<User>>() {});
emp1.stream().forEach(x -> System.out.println(x));
/*for (User person : user) {
Employee employee= new Employee.EmployeeBuilder().requiredFirstName(person.getFirstName()).build();
System.out.println(employee);
} */
}
}
Problem: When I run this code all I get are the 1st names. Git and Brian. I am not getting the last names or website.
Can someone please suggest what am I missing? Thanks in advance for your time.

problem was i register users with name not Uid so when i request name and phone got n
long story short, I have one settlementItemeBase class as my father and two children. I want to make the father class parcelable so as extension happens, my two child classes be parcelable as well. I don't exactly know what I'm doing right or wrong. I searched little bit but nothing helped me.
here are my classes:
SettlementItemBase:
public class SettlementItemBase implements Parcelable{
public SettlementItemBase(){}
protected SettlementItemBase(Parcel in) {
}
public static final Creator<SettlementItemBase> CREATOR = new Creator<SettlementItemBase>() {
#Override
public SettlementItemBase createFromParcel(Parcel in) {
return new SettlementItemBase(in);
}
#Override
public SettlementItemBase[] newArray(int size) {
return new SettlementItemBase[size];
}
};
#Override
public int describeContents() {
return 0;
}
#Override
public void writeToParcel(Parcel dest, int flags) {
}
}
first child class:
public class FirstClass extends SettlementItemBase {
private int id;
private int cardId;
private String cardNumber;
private String expDate;
private String currency;
private String url;
public FirstClass(){
id = 0;
cardId = 0;
cardNumber = "";
expDate = "";
currency = "";
url = "";
}
protected FirstClass(Parcel in) {
super(in);
id = in.readInt();
cardId = in.readInt();
cardNumber = in.readString();
expDate = in.readString();
currency = in.readString();
url = in.readString();
}
#Override
public void writeToParcel(Parcel dest, int flags) {
dest.writeInt(id);
dest.writeInt(cardId);
dest.writeString(cardNumber);
dest.writeString(expDate);
dest.writeString(currency);
dest.writeString(url);
}
public int getId() {
return id;
}
public int getCardId() {
return cardId;
}
public String getCardNumber() {
return cardNumber;
}
public String getExpDate() {
return expDate;
}
public String getCurrency() {
return currency;
}
public String getUrl() {
return url;
}
}
second child class:
public class SecondClass extends SettlementItemBase{
private int id;
private String currency;
private String accountNumber;
private String ibanNumber;
public SecondClass(int id, String currency,
String accountNumber, String ibanNumber){
this.id = id;
this.currency = currency;
this.accountNumber = accountNumber;
this.ibanNumber = ibanNumber;
}
protected SecondClass(Parcel in){
super(in);
id = in.readInt();
currency = in.readString();
accountNumber = in.readString();
ibanNumber = in.readString();
}
#Override
public void writeToParcel(Parcel dest, int flags) {
dest.writeInt(id);
dest.writeString(currency);
dest.writeString(accountNumber);
dest.writeString(ibanNumber);
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getCurrency() {
return currency;
}
public String getAccountNumber() {
return accountNumber;
}
public String getIbanNumber() {
return ibanNumber;
}
}
I'm passing and getting an ArrayList of both child class' items with intent putParcelableArrayListExtra and getParcelableArrayListExtra methods and get the following error:
Parcel android.os.Parcel#2d0fde33: Unmarshalling unknown type code 3276849 at offset 172
any help would be appreciated 3>
well I'm posting this for those who may run into the same problem as me.
the problem was solved after adding the Creator statement to the child classes.
for one of the child classes it would be like:
public static final Creator<FirstClass> CREATOR = new Creator<FirstClass>() {
#Override
public FirstClass createFromParcel(Parcel in) {
return new FirstClass(in);
}
#Override
public FirstClass[] newArray(int size) {
return new FirstClass[size];
}
};
hope this helps. 3>

and in my logcat is this, i can see the json data but on my response.body returns null.
logcat
What should I do?
You are getting a response but there is issue in deserialization.
Reason being the Call<Student> is not the type it will be serialized to becuase you are getting a List of Students(JSONArray).
add this class
MyResponse
public class MyResponse {
#SerializedName("data")
#Expose
private List<Student> data = null;
public List<Student> getData() {
return data;
}
public void setData(List<Student> data) {
this.data = data;
}
}
and change your call to:
#GET("getJson")
Call<MyResponse> getStudentDetails();
Now you will get response body
and how to retrive?
List<Student> students = response.body().getData();
This will do..:)
I have the code and xml and xml and cannot read the xml and believe that it is for the attribute. how can I read the attribute?
This is the code:
#XmlRootElement(name = "reimpresiones")
public class RePrint {
private Integer id;
private String document;
private String numberDocument;
private String extraction;
private String client;
private String groupExtraction;
private String route;
private String deliveryNote;
private String date;
private List<RePrint> reprintList;
public RePrint() {
}
#XmlAttribute(name = "id")
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
#XmlElement(name = "client")
public String getClient() {
return client;
}
public void setClient(String client) {
this.client = client;
}
#XmlElement(name = "document")
public String getDocument() {
return document;
}
public void setDocument(String document) {
this.document = document;
}
#XmlElement(name = "numberDocument")
public String getNumberDocument() {
return numberDocument;
}
public void setNumberDocument(String numberDocument) {
this.numberDocument = numberDocument;
}
#XmlElement(name = "extraction")
public String getExtraction() {
return extraction;
}
public void setExtraction(String extraction) {
this.extraction = extraction;
}
#XmlElement(name = "groupExtraction")
public String getGroupExtraction() {
return groupExtraction;
}
public void setGroupExtraction(String groupExtraction) {
this.groupExtraction = groupExtraction;
}
#XmlElement(name = "route")
public String getRoute() {
return route;
}
public void setRoute(String route) {
this.route = route;
}
#XmlElement(name = "deliveryNote")
public String getDeliveryNote() {
return deliveryNote;
}
public void setDeliveryNote(String deliveryNote) {
this.deliveryNote = deliveryNote;
}
#XmlElement(name = "date")
public String getDate() {
return date;
}
public void setDate(String date) {
this.date = date;
}
#XmlElement(name = "reimprension")
public List<RePrint> getReprintList() {
return reprintList;
}
public void setReprintList(List<RePrint> reprintList) {
this.reprintList = reprintList;
}
}
This is the xml where there is a list of elements. I want to read "id" but i cannot.
