Question

I'm trying to display data into TextViews. I'm new to Retrofit and would appreciate any help and tip(s). The following are what I have so far.

API Client:

public class ApiClient {
    public static final String BASE_URL = ("http://10.1.11.11/");
    private static Retrofit retrofit = null;

    public static Retrofit getClient() {
        if (retrofit==null) {
            retrofit = new Retrofit.Builder()
                    .baseUrl(BASE_URL)
                    .addConverterFactory(GsonConverterFactory.create())
                    .build();
        }
        return retrofit;
    }
}

API Service:

public interface ApiService {
    @FormUrlEncoded
    @GET("/lara/getprofile.php?id=")
    Call<Profile> getMyProfile(@Query("id") String id);
}

Getter and setter:

public class Profile {
    @SerializedName("PID")
    @Expose
    private String pid;

    @SerializedName("First_Name")
    @Expose
    private String fname;

    @SerializedName("Last_Name")
    @Expose
    private String lname;

    @SerializedName("Team_Lead")
    @Expose
    private String teamlead;

    public Profile(String pid, String fname, String lname, String teamlead) {
        this.pid = pid;
        this.fname = fname;
        this.lname = lname;
        this.teamlead = teamlead;
    }


    public String getPid() {
        return pid;
    }

    public void setPid(String pid) {
        this.pid = pid;
    }

    public String getFname() {
        return fname;
    }

    public void setFname(String fname) {
        this.fname = fname;
    }

    public String getLname() {
        return lname;
    }

    public void setLname(String lname) {
        this.lname = lname;
    }

    public String getTeamlead() {
        return teamlead;
    }

    public void setTeamlead(String teamlead) {
        this.teamlead = teamlead;
    }
}

Displaying data into TextViews:

  private void getProfile(final String id){
    ApiService apiService = ApiClient.getClient().create(ApiService.class);

    Call<Profile> call = apiService.getMyProfile(id);
    call.enqueue(new Callback<Profile>() {
        @Override
        public void onResponse(Call<Profile> call, Response<Profile> response) {

            progressDialog.dismiss();
            Profile p = response.body();

            pid.setText(p.getPid());
            fname.setText(p.getFname());
            lname.setText(p.getLname());
            teamlead.setText(p.getTeamlead());
        }

        @Override
        public void onFailure(Call<Profile> call, Throwable t) {
            //progressDialog.dismiss();
            Toast.makeText(ProfilePage.this, "Failed to load." + t, Toast.LENGTH_LONG).show();
    }
    });
}

JSON fields that I'm trying to display to TextViews:

I'm getting the following error message:

Answer 1

Use List Because its array and parse the array of objecct:

public interface ApiService {
@FormUrlEncoded
@GET("/lara/getprofile.php?id=")
Call<List<Profile>> getMyProfile(@Query("id") String id);
}

Instead:

public interface ApiService {
@FormUrlEncoded
@GET("/lara/getprofile.php?id=")
Call<Profile> getMyProfile(@Query("id") String id);
}

Answer 2

You are doing wrong because you are parsing your response As Object for Profile but actually, a response in the array means you need to parse response as an array, replace your API service as bellow also change calling as bellow

public interface ApiService {
    @FormUrlEncoded
    @GET("/lara/getprofile.php?id=")
    Call<List<Profile>> getMyProfile(@Query("id") String id);
}



private void getProfile(final String id){
  ApiService apiService = ApiClient.getClient().create(ApiService.class);
    Call<List<Profile>> call = apiService.getMyProfile(id);
    call.enqueue(new Callback<List<Profile>>() {
        @Override
        public void onResponse(Call<List<Profile>> call, Response<List<Profile>> response) {

            progressDialog.dismiss();
            List<Profile> p = response.body();
            if(p!=null && p.size()>0){
            pid.setText(p.get(0).getPid());
            fname.setText(p.get(0).getFname());
            lname.setText(p.get(0).getLname());
            teamlead.setText(p.get(0).getTeamlead());}
        }

        @Override
        public void onFailure(Call<List<Profile>> call, Throwable t) {
            //progressDialog.dismiss();
            Toast.makeText(ProfilePage.this, "Failed to load." + t, Toast.LENGTH_LONG).show();
    }
    });
}
