How to showing response string in a textview? - android-studio

Result: {"Status":"OK","Message":"Report Genarated.","Result":"JVBERi0xLjUKJeLjz9MKMSAwIG9iago8PC9UeXBlL0ZvbnQvU3VidHlw"}
I am getting these response from the post api calling.Now How can i am get the Result string value.
Code:
holder.downloadBtn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
manager = new UtilityBillManager(context, AppBaseController.get().getUserSettings());
manager.UserTransactionReceiptReport(listener,billReceiptReport); //This the api calling
}
});
}
private final TransactionReportListener listener = new TransactionReportListener() {
#Override
public void didFetch(UserReportResponse response, String message) {
}
#Override
public void didError(String message) {
}
};
UserReponse is a Model which have String status,message, result.

Just use getResult() getter of Model class
See the below code
// add this condition to prevent app crashing.
if (response.body().getResult()!=null){
textView.setText(response.body().getResult()); // getResult() is your getters of the Model Class.
}
Hope it helps.

I Want To Itemonclicklister in Fragment on Spinner

This Is Main Fragment

apiInterface api = retrofit.create(apiInterface.class);
Call<List<Blocks>>call = api.getVaccineBlocks();
call.enqueue(new Callback<List<Blocks>>() {

if (response.code() == 200) {
block = response.body();
spinnerada();
dialog.cancel();
}else{
dialog.cancel();

This Is Blocks Model
model:
package com.smmtn.book.models;

public String getId() {
return id;
}
public void setId(String id) {
this.id = id;

this.blockSlug = blockSlug;
}
}
here i need onitemclick with blockslug please any one can help, am new to android so i need some example.when on click i want take blockslug and load another method with that blockslug,like will get data from u "http://example.com/block/"+blockslug
i want to get blockslug from selected block
i hope guys i will get help
and sorry for my bad English,
First of all, you need to implement setOnItemSelectedListener. Refer to this https://stackoverflow.com/a/20151596/9346054
Once you selected the item, you can call them by making a new method. Example like below
public void onItemSelected(AdapterView<?> parent, View view, int pos,long id) {
Toast.makeText(parent.getContext(),
"OnItemSelectedListener : " + parent.getItemAtPosition(pos).toString(),
Toast.LENGTH_SHORT).show();
final String itemSelected = parent.getItemAtPosition(pos).toString();
showBlockSlug(itemSelected);
}
And then, at the method showBlockSlug() , you can call Retrofit.
private void showBlockSlug(final String blockslug){
final String url = "http://example.com/block/"+ blockslug;
//Do your stuff...
}

RxJava subscribe onNext is not called when adding element asynchronously

I have a Observable like this
Observable<String> gitHubRepoModelObservable;
I have this code
repoNames = new ArrayList<String>();
gitHubRepoModelObservable = Observable.fromIterable(repoNames);
repoNames.add("Hello");
gitHubRepoModelObservable
.subscribeOn(Schedulers.io())
.observeOn(AndroidSchedulers.mainThread())
.subscribe(new Observer<String>() {
#Override
public void onSubscribe(Disposable d) {
}
#Override
public void onNext(String s) {
System.out.println(s);
}
#Override
public void onError(Throwable e) {
}
#Override
public void onComplete() {
}
});
repoNames is just a list of string. When I am adding a string "hello" manually the onNext is getting called but when I am adding string from a API call like bellow
call.enqueue(new Callback<List<GitHubRepoModel>>() {
#Override
public void onResponse(Call<List<GitHubRepoModel>> call, Response<List<GitHubRepoModel>> response) {
for (GitHubRepoModel repo : response.body()) {
repoNames.add(repo.getName());
}
}
#Override
public void onFailure(Call<List<GitHubRepoModel>> call, Throwable t) {
}
});
I am adding strings from the API into the repoNames the "onNext" is not getting called.
I have seen
.addCallAdapterFactory(RxJava2CallAdapterFactory.create())
can be added while initializing retrofit but I want to better understand the rxjava so in this experiment it is not working.
Please help!
It can't not be work.
When you create you api request and try subscribe you list is emty, so Observable does not work.
You need to create Observable such, that your subcribe will run your request!
Observable<String> gitHubRepoModelObservable = Observable.create(
new Observable.OnSubscribe<String>() {
#Override
public void call(final Subscriber<? super String> sub) {
call.enqueue(new Callback<List<GitHubRepoModel>>() {
#Override
public void onResponse(Call<List<GitHubRepoModel>> call, Response<List<GitHubRepoModel>> response) {
for (GitHubRepoModel repo : response.body()) {
sub.onNext(repo.getName()); //send result to rx
}
sub.onCompleted();
}
#Override
public void onFailure(Call<List<GitHubRepoModel>> call, Throwable t) {
}
});
}
}
);
gitHubRepoModelObservable
.subscribeOn(Schedulers.io())
.observeOn(AndroidSchedulers.mainThread())
.subscribe(new Observer<String>() {
#Override
public void onNext(String s) {
System.out.println(s);
}
#Override
public void onCompleted() {
}
#Override
public void onError(Throwable e) {
}
});
Why would onNext get called if you are just adding element to plain List?
In the first example you are seeing onNext being called because modified list is passed through the stream during subscribe.
Create Subject ex. PublishSubject and pass list to Subject.onNext in onResponse, subscribe to it and you will get what you want.
Second option is adding RxJava2CallAdapterFactory and return Observable<Response<List<GithubRepoModel>>>. This way you don't need to create stream yourself.

How update Room DB with API response if there is not data?

I am trying to update my database (room) with the response of my call api if my database table is empty and return to my recyclerview
API
#GET("user/patient/")
Flowable<ResponsePatient> getPatients(#Header("Authorization") String userToken);
FactoryData.class
public Flowable<List<Patient>> getPatientFromApi(){
String token = preferences.getValue(SDConstants.token);
return apiNetwork.getPatients(token).map(new Function<ResponsePatient, List<Patient>>() {
#Override
public List<Patient> apply(ResponsePatient responsePatient) throws Exception {
return PatientMapper.transform(responsePatient);
}
});
}
public Flowable<List<Patient>> listPatient(){
return appDataBase.patientDao().listPatient()
.switchIfEmpty(getPatientFromApi())
.doOnNext(s -> appDataBase.patientDao().saveAll(s));
}
I not sure how to do this. I appreciate any help.
Finally I can solve my problem.
public Flowable<List<Patient>> getPatient(){
return getPatientFromlocal()
.take(1)
.filter(list -> !list.isEmpty())
.switchIfEmpty(
Flowable.defer(() -> getPatientFromApi()));
}
public Flowable<List<Patient>> getPatientFromlocal(){
return appDataBase.patientDao().listPatient();
}
public Flowable<List<Patient>> getPatientFromApi(){
String token = preferences.getValue(SDConstants.token);
return apiNetwork.getPatients(token).map(new Function<ResponsePatient, List<Patient>>() {
#Override
public List<Patient> apply(ResponsePatient responsePatient) throws Exception {
return PatientMapper.transform(responsePatient);
}
}).doOnNext(new Consumer<List<Patient>>() {
#Override
public void accept(List<Patient> patients) throws Exception {
appDataBase.patientDao().saveAll(patients);
}
});
}

I am getting this response :

I have given the proper url then why is it taking only half of it?
I have tried the example from https://code.tutsplus.com/tutorials/sending-data-with-retrofit-2-http-client-for-android--cms-27845. This example and the link given in the example are working fine, but if I do the same with my url then I get the above error
I Hope kindly check your parsing issues may occurred.
#Override
public void onFailure(retrofit2.Call<Items> call, Throwable t) {
System.out.println("onFailure"+call);
//add this lije you got exceptions.
t.printStackTrace();
}
Change your Endpoints interface for this:
public interface Endpoints {
#POST("userregister/newuser")
#FormUrlEncoded
Call<Items> newuser(#Field("Data") String Data);
}
Note that I removed the trailing slash /. This way Retrofit appends the path you defined to the BASE_URL.
refer to the docs for Retrofit.Builder for a more detailed explanation, but pay particular attention to these bits:
Base URLs should always end in /.
A trailing / ensures that endpoints values which are relative paths
will correctly append themselves to a base which has path components.
...
Endpoint values which contain a leading / are absolute.
Absolute values retain only the host from baseUrl and ignore any
specified path components.
as presently written, the path referenced in your call to Endpoints.newuser() is absolute, and therefore the path segments after the host in your base URL are dropped (as this is the documented behavior).
therefore, you should change your Endpoints interface to use relative paths instead, like so:
public interface Endpoints {
#POST("userregister/newuser")
#FormUrlEncoded
Call<Items> newuser(#Field("Data") String Data);
}

How can I return data in method from Retrofit i am confused?

I am confused please can you help me? I read similar questions but its is not clear for me, thanks in advance for your patient and attention.
I want to return to onCreate data which retrieved from API call using Retrofit. Here is my function where i call Retrofit.
private void loadTimeZoneAPI(double latitude, double longitude, long timestamp, String apiKeyTz) {
String lat = Double.toString(latitude);
String lon = Double.toString(longitude);
String time = Long.toString(timestamp);
serviceTZ.getDataTZ(lat+","+lon, time, apiKeyTz).enqueue(new Callback<TimeZoneGoogle>() {
#Override
public void onResponse(Call<TimeZoneGoogle> call, Response<TimeZoneGoogle> response) {
TimeZoneGoogle result = response.body();
timeZone = result.getTimeZoneId();
}
#Override
public void onFailure(Call<TimeZoneGoogle> call, Throwable t) {
}
});
}
How i will return timeZone value to onCreate where i will use for calculation.
You need a callback listener for your data in MainActivity or any activity you have used for view.
for example:make interface like this
interface RetrofitListener{
onDataLoad(TimeZoneGoogle timeZoneGoogle);
}
then give a reference in Activity from which you are calling Retrofit class
public class ActivityTest extends AppCompatActivity implements ActivityTest.RetrofitListener {
RetrofitCall retrofitListener;
#Override
protected void onCreate(#Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_test);
retrofitListener = new RetrofitCall(this);
}
}
and here in RetrofitCall class
private class RetrofitCall {
private RetrofitListener retrofitListener;
public RetrofitCall(RetrofitListener retrofitListener) {
this.retrofitListener = retrofitListener;
}
void getData(){
getDataTZ(lat+","+lon, time, apiKeyTz).enqueue(new Callback<TimeZoneGoogle>() {
#Override
public void onResponse(Call<TimeZoneGoogle> call, Response<TimeZoneGoogle> response) {
TimeZoneGoogle result = response.body();
timeZone = result.getTimeZoneId();
}
#Override
public void onFailure(Call<TimeZoneGoogle> call, Throwable t) {
}
});
}
}
