我正在尝试将数据显示到 TextViews . 我是新手 Retrofit 并感谢您的帮助和提示。以下是我目前掌握的情况。

API客户端:

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服务:

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

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;
    }
}

将数据显示到文本视图中:

  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();
    }
    });
}

我试图向TextView显示的JSON字段:

我收到以下错误消息:

使用List是因为它的数组和解析objecct的数组:

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

而是:

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

您做错了,因为您正在将响应解析为的对象 Profile 但实际上,数组中的响应意味着您需要将响应解析为数组,将API服务替换为bellow,也将调用更改为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();
    }
    });
}
