I'm new to Retrofit and JSON and I don't really know how to parse the next json string:
{
"weight":[
{ "bmi":21,
"date":"2016-12-09",
"fat":14.059000015258789,
"logId":1222222222222,
"source":"Aria",
"time":"11:58:24",
"weight":68
},
{ "bmi":21.83,
"date":"2016-12-14",
"logId":1222222222223,
"source":"Aria",
"time":"14:31:39",
"weight":70.7
}
]
}
I just want "weight" and "date" inside weight array. I've created a pojo class following some examples but it's not working.
Also when trying it with my pojo class I couldn't get "weight" as a string (I'll then use it as a double) using .string().
(I know using .toString() shows something like "com.myPackage.MyPojo@xxxx").
For now, I have only been able to get the whole json through ResponseBody:
Call<ResponseBody>call = repository.getFitbitApi().getData();
call.enqueue(new Callback<ResponseBody>() {
@Override
public void onResponse(Call<ResponseBody> call, retrofit2.Response<ResponseBody> response) {
try {
System.out.println(response.body().string());
} catch (IOException e) {
e.printStackTrace();
}
}
@Override
public void onFailure(Call<ResponseBody> call, Throwable t) {
}
});
What am I doing wrong? Here are my pojo classes, just an attempt...:
public class WeightList {
@SerializedName("weight")
@Expose
private ArrayList<WeightLogFitbit> weight = new ArrayList<>();
public WeightList(){
}
public ArrayList<WeightLogFitbit> getWeight() {
return weight;
}
public void setWeight(ArrayList<WeightLogFitbit> weight) {
this.weight = weight;
}
} And:
public class WeightLogFitbit {
//Variables in my JSON
@SerializedName("bmi")
@Expose
private String bmi;
@SerializedName("date")
@Expose
private String date;
@SerializedName("logId")
@Expose
private String logId;
@SerializedName("source")
@Expose
private String source;
@SerializedName("time")
@Expose
private String time;
@SerializedName("weight")
@Expose
private double weight;
@SerializedName("fat")
@Expose
private String fat;
public WeightLogFitbit(){}
//Getters and setters
public double getWeight() {
return weight;
}
public void setWeight(double weight) {
this.weight = weight;
}
public String getDate() {
return date;
}
public void setDate(String date) {
this.date = date;
}
public String getSource() {
return source;
}
public void setSource(String source) {
this.source = source;
}
public String getBmi(){
return bmi;
}
public void setBmi(String bmi) {
this.bmi = bmi;
}
//
public String getFat(){
return fat;
}
public void setFat(String fat) {
this.fat = fat;
}
public String getTime() {
return time;
}
public void setTime(String time) {
this.time = time;
}
public String getLogId() {
return logId;
}
public void setLogId(String logId) {
this.logId = logId;
}
}
NOTE: I'm using RxSocialConnect library, which implements RxJava, Retrofit 2, OkHttp3 and gson, just in case. I did this following this example.
Rest of classes I'm using:
public class FitbitBtnActivity extends AppCompatActivity {
private FitbitRepository repository;
@Override protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_fitbit_btn);
repository = new FitbitRepository();
setUpFitbit();
}
private void setUpFitbit() {
findViewById(R.id.fitbitbtn).setOnClickListener(v ->
RxSocialConnect.with(this, repository.fitbitService())
.subscribe(response -> response.targetUI().showToken(response.token()),
error -> showError(error))
);
findViewById(R.id.retrievebtn).setOnClickListener(v -> {
Call<ResponseBody>call = repository.getFitbitApi().getData();
call.enqueue(new Callback<ResponseBody>() {
@Override
public void onResponse(Call<ResponseBody> call, retrofit2.Response<ResponseBody> response) {
try {
System.out.println(response.body().string());
} catch (IOException e) {
e.printStackTrace();
}
}
@Override
public void onFailure(Call<ResponseBody> call, Throwable t) {
}
});
//Original code from example in RxSocialConnect
/*.subscribeOn(Schedulers.io())
.observeOn(AndroidSchedulers.mainThread())
.subscribe(new Action1<Object>() {
@Override
public void call(Object user) {
FitbitBtnActivity.this.showUserProfile(user.toString());
}
},
error -> FitbitBtnActivity.this.showError(error));*/
}
);
}
And:
public class FitbitRepository {
private final FitbitApiRest fitbitApi;
public FitbitRepository() {
fitbitApi = initFitbitApiRest();
}
private FitbitApiRest initFitbitApiRest() {
OkHttpClient client = new OkHttpClient.Builder()
.addInterceptor(new OAuth2Interceptor(FitbitApi20.class))
.build();
return new Retrofit.Builder()
.baseUrl(FitbitApiRest.URL_BASE)
.client(client)
.addCallAdapterFactory(RxJavaCallAdapterFactory.create())
.addConverterFactory(GsonConverterFactory.create())
.build().create(FitbitApiRest.class);
}
FitbitApiRest getFitbitApi() {
return fitbitApi;
}
interface FitbitApiRest {
String URL_BASE = "https://api.fitbit.com";
@GET("myrequest.json")
Call<ResponseBody> getData();
}
OAuth20Service fitbitService() {
final String client_id = "xxxxx";
final String client_secret = "1xxxxxxxxxxxxxxxxxx";
final String redirect_uri = "http://example.com";
final String permissions = "weight";
return new ServiceBuilder()
.apiKey(client_id)
.apiSecret(client_secret)
.callback(redirect_uri)
.scope(permissions)
.build(FitbitApi20.instance());
}
}
