i'm using retrofit for service calls.it's return 5 data sets.each data set contain 6 values.each data set contain one actual values and others are null.how can get actual values without null values?
POST man response is like bellow
{
"status": true,
"message": "successfully count new orders",
"data": [
{
"order_count": "3"
},

}
]
}

I am working with MVVM pattern. I have just started it and i have done it successfully.
But I don't understand how to add progress bar for showing and hide as we normally do for API calls.
I am not using data binding. So how can i use progress bar for showing and hide it.
For Login
public class LoginRepository {
private DATAModel dataModel = new DATAModel();
private MutableLiveData<DATAModel> mutableLiveData = new MutableLiveData<>();
private Application application;
public LoginRepository(Application application) {
this.application = application;
}
public MutableLiveData<DATAModel> getMutableLiveData(String username, String password) {
APIRequest apiRequest = RetrofitRequest.getRetrofit().create(APIRequest.class);
JsonLogin jsonLogin = new JsonLogin(Constants.DEVICE_TYPE, Functions.getDeviceId(application.getApplicationContext()), Constants.APP_VERSION, Constants.API_VERSION, Functions.getTimeStamp(), Functions.getDeviceModel(), Build.VERSION.RELEASE, username, password);
Call<APIResponseLogin> call = apiRequest.getUsersDetails(jsonLogin);
call.enqueue(new Callback<APIResponseLogin>() {
#Override
public void onResponse(Call<APIResponseLogin> call, Response<APIResponseLogin> response) {
APIResponseLogin apiResponse = response.body();
if (apiResponse != null && apiResponse.getStatuscode() == 0) {
if (apiResponse.getDataModel() != null) {
dataModel = apiResponse.getDataModel();
mutableLiveData.setValue(dataModel);
}
} else if (apiResponse != null && apiResponse.getStatuscode() == 1) {
Log.v("AAAAAAAAA", apiResponse.getStatusmessage());
}
}
#Override
public void onFailure(Call<APIResponseLogin> call, Throwable t) {
Log.v("ErrorResponse", t.getMessage() + " : " + call.request().toString());
}
});
return mutableLiveData;
}
Activity Code
void loginCall() {
loginViewModel.getUserDetails(editTextUsername.getText().toString().trim(), editTextPassword.getText().toString().trim()).observe(this, new Observer<DATAModel>() {
#Override
public void onChanged(#Nullable DATAModel dataModel) {
if (dataModel != null) {
Userdetails userdetails = dataModel.getUserdetails();
List<ContactTypes> contactTypes = dataModel.getContactTypes();
if (userdetails != null) {
MySharedPreferences.setCustomPreference(LoginActivity.this, Constants.SHAREDPREFERENCE_USERDETAILS, userdetails);
MySharedPreferences.setStringPreference(LoginActivity.this, Constants.SHAREDPREFERENCE_USER_ID, userdetails.getUserId());
}
if (contactTypes != null) {
MySharedPreferences.setCustomArrayList(LoginActivity.this, Constants.SHAREDPREFERENCE_CONTACTTYPES, contactTypes);
}
Intent i = new Intent(LoginActivity.this, MainActivity.class);
startActivity(i);
finish();
}
}
});
}
Advanced help would be appreciated!
When you call api that time you have to take one live variable which shows your api is in loading mode or not and after success or failure you have to update that variable.
After observe that variable in your activity or fragment class and show or hide your progress.
public class LoginRepository {
private DATAModel dataModel = new DATAModel();
private MutableLiveData<DATAModel> mutableLiveData = new MutableLiveData<>();
private Application application;
private MutableLiveData<Boolean> progressbarObservable;
public LoginRepository(Application application) {
this.application = application;
}
public MutableLiveData<DATAModel> getMutableLiveData(String username, String password) {
// add below line
progressbarObservable.value = true
APIRequest apiRequest = RetrofitRequest.getRetrofit().create(APIRequest.class);
JsonLogin jsonLogin = new JsonLogin(Constants.DEVICE_TYPE, Functions.getDeviceId(application.getApplicationContext()), Constants.APP_VERSION, Constants.API_VERSION, Functions.getTimeStamp(), Functions.getDeviceModel(), Build.VERSION.RELEASE, username, password);
Call<APIResponseLogin> call = apiRequest.getUsersDetails(jsonLogin);
call.enqueue(new Callback<APIResponseLogin>() {
#Override
public void onResponse(Call<APIResponseLogin> call, Response<APIResponseLogin> response) {
// add below line
progressbarObservable.value = false
APIResponseLogin apiResponse = response.body();
if (apiResponse != null && apiResponse.getStatuscode() == 0) {
if (apiResponse.getDataModel() != null) {
dataModel = apiResponse.getDataModel();
mutableLiveData.setValue(dataModel);
}
} else if (apiResponse != null && apiResponse.getStatuscode() == 1) {
Log.v("AAAAAAAAA", apiResponse.getStatusmessage());
}
}
#Override
public void onFailure(Call<APIResponseLogin> call, Throwable t) {
// add below line
progressbarObservable.value = false
Log.v("ErrorResponse", t.getMessage() + " : " + call.request().toString());
}
});
return mutableLiveData;
}
}
Now, observe above variable in activity or fragment and based on that value hide or show your progress bar
public class LoginActivity extends AppCompatActivity {
...
#Override
protected void onCreate(Bundle savedInstanceState) {
...
observeLogin();
}
#Override
public void onClick(View view)
{
switch (view.getId()) {
case R.id.button_login:
// Do something
loginCall();
}
}
private void observeLogin() {
loginViewModel.progressbarObservable().observe(this, new Observer<Boolean>() {
#Override
public void onChanged(final Boolean progressObserve) {
if(progressObserve){
show your progress
}
else {
hide your progress
}
}
});
}
void loginCall() {
loginViewModel.getUserDetails(editTextUsername.getText().toString().trim(), editTextPassword.getText().toString().trim()).observe(this, new Observer<DATAModel>() {
#Override
public void onChanged(#Nullable DATAModel dataModel) {
if (dataModel != null) {
Userdetails userdetails = dataModel.getUserdetails();
List<ContactTypes> contactTypes = dataModel.getContactTypes();
if (userdetails != null) {
MySharedPreferences.setCustomPreference(LoginActivity.this, Constants.SHAREDPREFERENCE_USERDETAILS, userdetails);
MySharedPreferences.setStringPreference(LoginActivity.this, Constants.SHAREDPREFERENCE_USER_ID, userdetails.getUserId());
}
if (contactTypes != null) {
MySharedPreferences.setCustomArrayList(LoginActivity.this, Constants.SHAREDPREFERENCE_CONTACTTYPES, contactTypes);
}
Intent i = new Intent(LoginActivity.this, MainActivity.class);
startActivity(i);
finish();
}
}
});
}
}
I find it easier to write my own callback interface in this situation. Just not that this will be done synchronously so all will wait until your api call responds. But in such a case, a progress dialog would be havin the similar effect.
1.Create inteface:
public interface ProgressCallback{
void onDone(String message);
void onFail(String message);
}
Now in your method where you call the API
loginUser(String name, String password, ProgressCallback
progressCallback){
call.enqueue(new Callback<LoginData>() {
#RequiresApi(api = Build.VERSION_CODES.O)
#Override
public void onResponse(Call<LoginData> call, Response<LoginData> response) {
progressCallBack.onSuccess(response.message());
}
#Override
public void onFailure(Call<LoginData> call, Throwable t) {
progressCallBack.onFail(t.getMessage());
}
});
Now when you call the method
loginUser("John#doe.com", "applesgravity", new ProgressCallBack() {
#Override
public void onSuccess(String message) {
progressBar.setVisibility(View.INVISIBLE);
}
#Override
public void onFail(String message) {
progressBar.setVisibility(View.INVISIBLE);
}
});
I have used rxjava and retrofit to load data from backend and update the UI.
But there is no data displayed on section view. I have tested it, and the backend data load successful and the UI can be updated using fake data.
Are there something wrong when I use Rxjava?

Do you use an adapter? In this case adapter.notifyDataSetChanged();
Also, print yout error: throwable.printStackTrace(); in order to see if something goes wrong.
You need to add .observeOn(AndroidSchedulers.mainThread()) after you write subsribeOn() to tell your observable to perform your onNext callback on UI thread/MainThread.
I'm trying to get the data from Firebase, but when I debug my app I can see that the app has found the key I put, but I received no data on the value:
DatabaseReference taxiref = childRef.child(chapa);
taxiref.addValueEventListener(new ValueEventListener() {
#Override
public void onDataChange(DataSnapshot dataSnapshot) {
Sesion.taxis.add(dataSnapshot.getValue(Taxi.class));
}
#Override
public void onCancelled(DatabaseError databaseError) {
}
});
As you can see in the following code, that my structure from Firebase:
"taxis" : {
"bbb222" : {
"año" : 1998,
"modelo" : "Gol",
"ubicaciones" : {
"u1" : {
"fecha" : "20-12-2016 12:30",
"latitud" : 31231231,
"longitud" : 2131241
},
"u2" : {
"fecha" : "20-12-2016 12:31",
"latitud" : 31231232,
"longitud" : 2131243
}
}
},
And as you can see on the following image when I debugged the code the key I got is correct, but I didn't receive any value, could somebody help me with that?
Here its the taxi.java class:
public class Taxi {
private String año;
private String modelo;
private String chapaTaxi;
private LinkedList<Ubicaciones> ubicaciones;
public void diagramarRecorrido() {
for (Ubicaciones u : getUbicaciones()) {
u.ubicarMapa();
}
}
public String getAño() {
return año;
}
public void setAño(String año) {
this.año = año;
}
public String getModelo() {
return modelo;
}
public void setModelo(String modelo) {
this.modelo = modelo;
}
public String getChapaTaxi() {
return chapaTaxi;
}
public void setChapaTaxi(String chapaTaxi) {
this.chapaTaxi = chapaTaxi;
}
public LinkedList<Ubicaciones> getUbicaciones() {
return ubicaciones;
}
public void setUbicaciones(LinkedList<Ubicaciones> ubicaciones) {
this.ubicaciones = ubicaciones;
}
}
Sorry guys my bad, childRef was a variable:
private static DatabaseReference childRef= ref.child("taxis");
and that was the problem as you can see the child its taxis but I had Taxis thats why I never got any results from the firebase, thanks to all for all your help.
Am working on one android project. i stored the getting response in the ArrayList while parsing from the JsonArray. now i want just display the values to required text views.
Here am doing.
public void updateRedemptionRequestDetails(){
//Dismiss dialog
dlgProgress.dismiss();
// Get the status
String status=redemptionRequestDetailsResponse.getStatus();
if(status.equals("success")){
List<RedemptionRequestDetailsResource> redemptionRequestDetailsResource = redemptionRequestDetailsResponse.getData();
if(!redemptionRequestDetailsResource.isEmpty() && redemptionRequestDetailsResource.size()==0 ){
redemptionRequestDetailsResources.addAll(redemptionRequestDetailsResource);
populateRedemptionDetails(redemptionRequestDetailsResources);
}
}else if ( status.equals("failed")) {
//Show toast based on error code
generalMethods.showToastMessage(context,redemptionRequestDetailsResponse.getErrorcode());
}
}
Can anyone please shed some lights on this.how can i get the values in specified string and display them.
Here my model class
public class RedemptionRequestDetailsResource {
private String rdmId;
private String rdmUniqueBatchTrackingId;
private String rdmLoyaltyId;
private String rdmStatus;
private String rdmCashPaymentStatus;
private String rdmProductCode;
public String getRdmId() {
return rdmId;
}
public void setRdmId(String rdmId) {
this.rdmId = rdmId;
}
public String getRdmUniqueBatchTrackingId() {
return rdmUniqueBatchTrackingId;
}
public void setRdmUniqueBatchTrackingId(String rdmUniqueBatchTrackingId) {
this.rdmUniqueBatchTrackingId = rdmUniqueBatchTrackingId;
}
public String getRdmLoyaltyId() {
return rdmLoyaltyId;
}
public void setRdmLoyaltyId(String rdmLoyaltyId) {
this.rdmLoyaltyId = rdmLoyaltyId;
}
public String getRdmStatus() {
return rdmStatus;
}
public void setRdmStatus(String rdmStatus) {
this.rdmStatus = rdmStatus;
}
public String getRdmCashPaymentStatus() {
return rdmCashPaymentStatus;
}
public void setRdmCashPaymentStatus(String rdmCashPaymentStatus) {
this.rdmCashPaymentStatus = rdmCashPaymentStatus;
}
public String getRdmProductCode() {
return rdmProductCode;
}
public void setRdmProductCode(String rdmProductCode) {
this.rdmProductCode = rdmProductCode;
}
}
here my populateRedemptionDetails method
public void populateRedemptionDetails(List<RedemptionRequestDetailsResource> requestDetailsResource) {
List<RedemptionRequestDetailsResource> redemptionRequestDetailsResource = requestDetailsResource;
TextView txtLoyaltyId = (TextView)rootView.findViewById(R.id.txtLoyaltyId);
txtLoyaltyId.setText(redemptionRequestDetailsResource.getRdmLoylatyId());
}
i tried like this but it throwing error.
The if condition is wrong, it will never enter:
if (!redemptionRequestDetailsResource.isEmpty() && redemptionRequestDetailsResource.size()==0) {
}
it should be:
if (!redemptionRequestDetailsResource.isEmpty()) {}
also, small tip, when using equals, you should put the constant on the left side of the call, like this:
"success".equals(status)
this is to prevent NullPointerExceptions
