im trying to parse information from this website http://www.petwave.com/Dogs/Breeds/Airedale-Terrier.aspx.. at the end theres a table with a few attributes with star ratings. Right now i have only values with strings parsing.. is there anyway to parse ratings from a website? I would want to change these values such as Lifespan and origin into the star values ? any idea how to do this?

Here I can see two APIs. But I am not sure which to which API you are getting 401. I can help you with the possibilities that you could check and please feel free to ask.
Assuming you are getting 401 for login API - the reason could be you are trying with wrong credentials.
Assuming you are getting 401 for getValue API - the reason could be you might passing the wrong token which you got from login response. Especially you need to cross-check the header with key and values.
And I have one suggestion - you could use header in Interceptor with retrofit setup itself.
I have a payload string and want to change it to values of entity. The payload as below:
{"resultCode":"200","resultMessage":"Success","consent":[{"name":"A","sourceSystem":"IGN","updateBy":"Admin","remark":"good","version":"1.0","updateDate":1600658621871},{"name":"B","sourceSystem":"IGN","updateBy":"Admin","remark":"good","version":"2.0","updateDate":1874819158457},{"name":"C","sourceSystem":"IGN","updateBy":"Admin","remark":"good","version":"3.0","updateDate":1358819159457}]}
And the entities:
public class ListConsentResponse {
private String resultCode;
private String resultMessage;
private List<ConsentDTO> consent;
public String getResultCode() {
return resultCode;
}
public void setResultCode(String resultCode) {
this.resultCode = resultCode;
}
public String getResultMessage() {
return resultMessage;
}
public void setResultMessage(String resultMessage) {
this.resultMessage = resultMessage;
}
public List<ConsentDTO> getConsent() {
return consent;
}
public void setConsent(List<ConsentDTO> consent) {
this.consent = consent;
}
}
public class ConsentDTO {
private String name;
private String sourceSystem;
private String updateBy;
private String remark;
private String version;
private Timestamp updateDate;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getSourceSystem() {
return sourceSystem;
}
public void setSourceSystem(String sourceSystem) {
this.sourceSystem = sourceSystem;
}
public String getUpdateBy() {
return updateBy;
}
public void setUpdateBy(String updateBy) {
this.updateBy = updateBy;
}
public String getRemark() {
return remark;
}
public void setRemark(String remark) {
this.remark = remark;
}
public String getVersion() {
return version;
}
public void setVersion(String version) {
this.version = version;
}
public Timestamp getUpdateDate() {
return updateDate;
}
public void setUpdateDate(Timestamp updateDate) {
this.updateDate = updateDate;
}
}
But when I parse to json using GsonBuilder :
ListConsentResponse listConsentResponse = Utility.createGsonObject()
.fromJson(payload, ListConsentResponse.class);
I have error:
com.google.gson.JsonSyntaxException: 1600658621871
Is there any way help me get parse the string with Timestamp value to entity. Or at least can I change the Timestamp value to String value in payload (For example change 1600658621871 to "1600658621871").
Thanks.
I am trying to get the value of a JSON response and display it in my textView and editText. But I get a null object reference as an error.
JSON Response:
{
"srNo": 1,
"date": "11/14/2019 12:00:00 AM",
"fieldEngineer": "Angel",
"accountName": "Forever 21 Megamall",
"irNo": 1,
"joNo": 1,
"address": "Mandaluyong City",
"contactPerson": "Jansen Babon",
"designation": "",
"contactNo": "",
"email": "",
"timeIn": "00:00:00",
"timeOut": "00:00:00",
"productType": "Security",
"problem": ""
}
Java class:
private void fetchData() {
JsonObject paramObject = new JsonObject();
Call<ResObj> call = userService.userLogin(paramObject);
call.enqueue(new Callback<ResObj>() {
#Override
public void onResponse(Call<ResObj> call, retrofit2.Response<ResObj> response) {
ResObj resObj = response.body();
String srNo = resObj.getSrNo();
String date = resObj.getDate();
String fieldEngineer = resObj.getFieldEngineer();
String accountName = resObj.getAccountName();
String irNo = resObj.getIrNo();
String joNo = resObj.getJoNo();
String address = resObj.getAddress();
String contactPerson = resObj.getContactPerson();
String designation = resObj.getDesignation();
String contactNo = resObj.getContactNo();
String email = resObj.getEmail();
String timeIn = resObj.getTimeIn();
String timeOut = resObj.getTimeOut();
String productType = resObj.getProductType();
String problem = resObj.getProblem();
//the response I am getting here is null
tvSrNo.setText(srNo);
etdate.setText(date);
etfieldengineer.setText(fieldEngineer);
etaccname.setText(accountName);
etirno.setText(irNo);
etjono.setText(joNo);
JsonObject workObj = new JsonObject();
try {
workObj.addProperty("srNo", resObj.getSrNo());
} catch (Exception e) {
e.printStackTrace();
}
}
#Override
public void onFailure(Call<ResObj> call, Throwable t) {
}
});
}
I tried using this tvSrNo.setText(resObj.getSrNo()) instead of tvSrNo.setText(srNo) but it still gets the same problem.
I am also using Retrofit.
I expect the result that JSON data will be placed in an editText or textView. But apparently, the response is getting null.

make sure to have Gson Converter in your retrofit instance
private static Retrofit getRetrofitInstance() {
return new Retrofit.Builder()
.baseUrl(ROOT_URL)
.addConverterFactory(GsonConverterFactory.create())
.build();
}
then make call and put the data in ArrayList

Note: NullPointerException because you did not declare SrNo inside the model class
Try to use a jason to java class generator:

first : Check response output,
you can Log.i or Toast it,,,
If your response not load or null ... - (the Problem in here)
Second : if respon Ok, Check your ResObj.getSrNo().
Print again... check
String srNo = resObj.getSrNo();
Log.i srNo... (problem or not)
Or checkyour Class Codebeautify
JsonObject paramObject = new JsonObject();
Call<ResObj> call = userService.userLogin(paramObject); // paramObject is empty object
You are passing empty JsonObject to your API parameter.
So you have to add parameter value to your paramObject. like this
try {
JsonObject paramObject = new JsonObject();
paramObject.addProperty("mobile", mobile);
// add other properties if you have
} catch (JSONException e) {
e.printStackTrace();
}
after that you should call your api like
Call<ResObj> call = userService.userLogin(paramObject);
As i am seeing the problem is in parsing, The retrofit can not mapping as your response is n't having ResObj as root.
{ "ResObj": { "srNo": 1, "date": "11/14/201912: 00: 00AM", "fieldEngineer": "Angel", "accountName": "Forever21Megamall", "irNo": 1, "joNo": 1, "address": "MandaluyongCity", "contactPerson": "JansenBabon", "designation": "", "contactNo": "", "email": "", "timeIn": "00: 00: 00", "timeOut": "00: 00: 00", "productType": "Security", "problem": "" } }
Modify your response or change your request
Call<JSONObject> call = userService.userLogin(paramObject);
Later in extract the values manually.
I have completed the Firebase Android Codelab here: https://codelabs.developers.google.com/codelabs/firebase-android/
When a message is sent, the name, photoUrl and text of the message have been grouped together like this:
I'm trying add a timestamp (ServerValue.TIMESTAMP) of that message in the group.
Code that's supposed to send message along with the name, photoUrl and text of the message + timestamp (originally from MainActivity.java):
mSendButton = (Button) findViewById(R.id.sendButton);
mSendButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
FriendlyMessage friendlyMessage = new FriendlyMessage(mMessageEditText.getText().toString(), mUsername,
mPhotoUrl, ServerValue.TIMESTAMP); //It's not supposed to be like this! What should I write instead?
mFirebaseDatabaseReference.child(MESSAGES_CHILD).push().setValue(friendlyMessage);
mMessageEditText.setText("");
mFirebaseAnalytics.logEvent(MESSAGE_SENT_EVENT, null);
}
});
With the code above, I can't add a timestamp as I want to. Why? What should I do exactly?
FriendlyMessage.java:
public class FriendlyMessage {
private String id;
private String text;
private String name;
private String photoUrl;
private Long creationDate;
public FriendlyMessage() {
}
public FriendlyMessage(String text, String name, String photoUrl, Long creationDate) {
this.text = text;
this.name = name;
this.photoUrl = photoUrl;
this.creationDate = creationDate;
}
public java.util.Map<String, String> getCreationDate() {
return ServerValue.TIMESTAMP;
}
#Exclude
public Long getCreationDateLong() {
return creationDate;
}
public void setCreationDate(Long creationDate) {
this.creationDate = creationDate;
}
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getText() {
return text;
}
public void setText(String text) {
this.text = text;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getPhotoUrl() {
return photoUrl;
}
public void setPhotoUrl(String photoUrl) {
this.photoUrl = photoUrl;
}
}
See entire Firebase Android Codelab original project here (without timestamp).
do like this
public class FriendlyMessage {
private String id;
private String text;
private String name;
private String photoUrl;
private Long creationDate;
public FriendlyMessage() {
}
public FriendlyMessage(String text, String name, String photoUrl) {
this.text = text;
this.name = name;
this.photoUrl = photoUrl;
}
public java.util.Map<String, String> getCreationDate() {
return ServerValue.TIMESTAMP;
}
#Exclude
public Long getCreationDateLong() {
return creationDate;
}
public void setCreationDate(Long creationDate) {
this.creationDate = creationDate;
}
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getText() {
return text;
}
public void setText(String text) {
this.text = text;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getPhotoUrl() {
return photoUrl;
}
public void setPhotoUrl(String photoUrl) {
this.photoUrl = photoUrl;
}
public Map<String, Object> toMap() {
HashMap<String, Object> result = new HashMap<>();
result.put("id", id);
result.put("text", text);
result.put("name", name);
result.put("photoUrl", photoUrl);
return result;
}
}
somewhere in your codes do this
Date someDate = new Date();
FriendlyMessage friendlyMessage = new FriendlyMessage("bla","bla","bla");
String key = mFirebaseDatabaseReference.child(MESSAGES_CHILD).push().getKey();
Map<String, Object> postValues = friendlyMessage.toMap();
postValues.put("creationDate", ServerValue.TIMESTAMP);
childUpdates.put("/"+MESSAGES_CHILD+"/" + key, postValues);
Map<String, Object> childUpdates = new HashMap<>();
mFirebaseDatabaseReference.updateChildren(childUpdates);
You must change the datatype of your creationDate variable from Long to Map. Because ServerValue.TIMESTAMP returns a Map value.
Here's how it should look:
public class FriendlyMessage {
private String id;
private String text;
private String name;
private String photoUrl;
private Map creationDate;
public FriendlyMessage() {
}
public FriendlyMessage(String text, String name, String photoUrl, Map CreationDate) {
this.text = text;
this.name = name;
this.photoUrl = photoUrl;
this.creationDate = creationDate;
}
public java.util.Map<String, String> getCreationDate() {
return ServerValue.TIMESTAMP;
}
public void setCreationDate(Map creationDate) {
this.creationDate = creationDate;
}
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getText() {
return text;
}
public void setText(String text) {
this.text = text;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getPhotoUrl() {
return photoUrl;
}
public void setPhotoUrl(String photoUrl) {
this.photoUrl = photoUrl;
}
}
I got a quite weird problem, forgive me if it became an attention problem, but I'm running on coffee right now!
I have this Json:
[
{
"address":"RS 239, Km 18,2 nº 4631 - Novo Hamburgo",
"closingTime":"06:00",
"description":"Curta como quiser.",
"distance":"6,328.35 km",
"iconUrl":"~\/Images\/Establishment\/Bar Alternativo.png",
"idEstablishment":5,
"name":"Bar Alternativo",
"openingTime":"22:30",
"phone":"(51) 3778-1820",
"type":"Casa Noturna \/ Balada"
}
]
And when I try deserialize this one using this code:
public static ArrayList<Establishment> serializeEstablishmentList(String json) {
ObjectMapper mapper = new ObjectMapper();
ArrayList<Establishment> establishments = null;
try {
establishments = mapper.readValue(json, new TypeReference<List<Establishment>>(){});
} catch (IOException e) {
e.printStackTrace();
}
return establishments;
}
My distance property do not get its value, image from debugger:
here goes my Establishment class:
public class Establishment {
private long idEstablishment;
private Drawable icon;
private String iconUrl;
private String name;
private String type;
private boolean workingStatus;
private String openingTime;
private String closingTime;

this.idEstablishment = idEstablishment;

this.iconUrl = iconUrl;
this.name = name;
this.type = type;
this.workingStatus = workingStatus;
this.openingTime = openingTime;
this.closingTime = closingTime;
this.distance = distance;
this.phone = phone;
this.description = description;
this.address = address;
}
public Establishment(long id, Drawable icon, String name, boolean workingStatus, String openingTime,
String closingTime, String distance) {
this.idEstablishment = id;

this.workingStatus = workingStatus;
this.openingTime = openingTime;
this.closingTime = closingTime;
this.distance = distance;
}

this.idEstablishment = idEstablishment;
}
public Drawable getIcon() {
return icon;
}
public void setIcon(Drawable icon) {
this.icon = icon;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public boolean getWorkingStatus() {
return workingStatus;
}
public String getWorkingStatusLabel(){
return workingStatus ? "Aberto" : "Fechado";
}
public void setWorkingStatus(boolean workingStatus) {
this.workingStatus = workingStatus;
}
public String getOpeningTime() {
return openingTime;
}
public void setOpeningTime(String openingTime) {
this.openingTime = openingTime;
}
public String getClosingTime() {
return closingTime;
}
public void setClosingTime(String closingTime) {
this.closingTime = closingTime;
}
public String getDistance() {
return distance;
}
public void setDistance(String distance) {
this.distance = this.distance;
}
public String getType() {
return type;
}
public void setType(String type) {
this.type = type;
}
public boolean isWorkingStatus() {
return workingStatus;
}
public String getIconUrl() {
return iconUrl;
}
public void setIconUrl(String iconUrl) {
this.iconUrl = iconUrl;
}
public String getPhone() {
return phone;
}
public void setPhone(String phone) {
this.phone = phone;
}
public String getDescription() {
return description;
}
public void setDescription(String description) {
this.description = description;
}
public String getAddress() {
return address;
}
public void setAddress(String address) {
this.address = address;
}
}
Any idea?
Your setter method is wrong:
public void setDistance(String distance) {
this.distance = this.distance;
}
This should be:
public void setDistance(String distance) {
this.distance = distance;
}
