  你需要创建2类

  package com.your.package;
  
  import java.util.List;
  import com.google.gson.annotations.Expose;
  import com.google.gson.annotations.SerializedName;
  
  public class Data {
  
  @SerializedName("light_id")
  @Expose
  private String lightId;
  @SerializedName("intensity")
  @Expose
  private List<Integer> intensity = null;
  @SerializedName("cct")
  @Expose
  private List<Integer> cct = null;
  
  public String getLightId() {
  return lightId;
  }
  
  public void setLightId(String lightId) {
  this.lightId = lightId;
  }
  
  public List<Integer> getIntensity() {
  return intensity;
  }
  
  public void setIntensity(List<Integer> intensity) {
  this.intensity = intensity;
  }
  
  public List<Integer> getCct() {
  return cct;
  }
  
  public void setCct(List<Integer> cct) {
  this.cct = cct;
  }
  
  }
  -----------------------------------com.your.package.GetScheduler.java-----------------------------------
  
  package com.your.package;
  
  import com.google.gson.annotations.Expose;
  import com.google.gson.annotations.SerializedName;
  
  public class GetScheduler {
  
  @SerializedName("status")
  @Expose
  private String status;
  @SerializedName("data")
  @Expose
  private Data data;
  
  public String getStatus() {
  return status;
  }
  
  public void setStatus(String status) {
  this.status = status;
  }
  
  public Data getData() {
  return data;
  }
  
  public void setData(Data data) {
  this.data = data;
  }
  
  }

  像这样改变你的回应

  public class GetScheduler {
     @SerializedName("status")
     private String status;
  
     @SerializedName("data")
     private DataClass data;
  
     public DataClass getData() {
          return data;
     }
  
     public void setData(DataClass data) {
         this.data= data;
     }
     public String getStatus() {
         return status;
     }
  
     public void setStatus(String status) {
        this.status = status;
      }
  
     public class DataClass {
          @SerializedName("light_id")
          private String light_id;
          @SerializedName("intensity")
          private int[] intensity;
          @SerializedName("cct")
          private int[] cct;
  
          public String getLight_id() {
              return light_id;
          }
  
          public void setLight_id(String light_id) {
              this.light_id = light_id;
          }
  
          public int[] getIntensity() {
              return intensity;
          }
  
          public void setIntensity(int[] intensity) {
              this.intensity = intensity;
          }
  
          public int[] getCct() {
              return cct;
          }
  
          public void setCct(int[] cct) {
              this.cct = cct;
          }
       }
  }
  

  如果您有阵列响应（我认为您没有），您必须使用 List<GetScheduler> 否则您必须只使用 GetScheduler

  所以改变一切

  List<GetScheduler>
  

  至

  GetScheduler
  

  API.java

  public interface API {
  @retrofit2.http.GET("/gateway_schedule")
       retrofit2.Call<GetScheduler> getSchedulerData();
  }
  

  和 Main.java

  private void getCCTAndIntensityValuesForPreset() {
      try {
          String url = "http://172.24.1.1:9000";
  
          Retrofit retrofit = null;
          Log.d("123", "retrofit");
  
          if (retrofit == null) {
              retrofit = new Retrofit.Builder()
                      .baseUrl(url)
                      .addConverterFactory(GsonConverterFactory.create())
                      .build();
              Log.d("123", "build();");
          }
          API service = retrofit.create(API.class);
  
          Call<GetScheduler> call=service.getSchedulerData();
          Log.d("123", "Call<GetScheduler> call = service.getSchedulerData();");
          call.enqueue(new Callback<GetScheduler>() {
              @Override
              public void onResponse(Call<GetScheduler> call, Response<GetScheduler> response) {
                  if(response!=null&&response.isSuccessful()){
                      String getLightId=response.body().getData().getLight_id().toString();
                      Toast.makeText(getApplicationContext(),"Light Id"+getLightId,Toast.LENGTH_LONG).show();
                      //String light_id=response.body()
                      int[] getIntensty=response.body().getData().getIntensity();
                      for(int i=0;i<getIntensty.length;i++){
                          getIntensty[i]=i;
                      }
                      int[] getCCT=response.body().getData().getCct();
                      for(int i=0;i<getCCT.length;i++){
                          getCCT[i]=i;
                          mCCT1.setProgress(getCCT[0]);
                          mCCT2.setProgress(getCCT[1]);
                      }
                  }
  
              };
  
              @Override
              public void onFailure(Call<GetScheduler> call, Throwable t) {
                  t.printStackTrace();
              }
  
  
          });
  
      }catch (Exception e) {
          e.printStackTrace();
      }
  
  }
  

  你必须像这样在 onResponse 中改变这一行

  String getLightId=response.body().getData().getLight_id().toString();
  

  我建议你添加登录onFailure（）并查看logCat并删除try catch

  @Override
  public void onFailure(Call<List<GetScheduler>> call, Throwable t) {
       t.printStackTrace();
  }
