java.lang.IllegalStateException：应为 BEGIN_OBJECT，但在第 1 行第 13571 列处为 BEGIN retrofit_ARRAY

如何解决java.lang.IllegalStateException：应为 BEGIN_OBJECT，但在第 1 行第 13571 列处为 BEGIN retrofit_ARRAY

我根据这里的答案更正了我的代码 Retrofit Expected BEGIN_OBJECT but was BEGIN_ARRAY

但我仍然遇到同样的错误。

我使用的 api 是 wordpress。

这是我的 json 响应示例

[
{
    "id": 5095,"parent_id": 0,"number": "5095","order_key": "wc_order_q7QgiKvemzxBd","created_via": "checkout","version": "5.0.0","status": "processing","currency": "USD" 
 },{
    "id": 5094,"parent_id": 5090,"number": "5094","order_key": "wc_order_PeUZBs1eRRgHC","created_via": "dokan","currency": "USD"
 }
]

ApiInterface 方法：

 @Headers({"Content-Type: application/json"})
@GET("wp-json/wc-analytics/orders")
Call<List<OrdersModel>> getAllOrdersWuCo();

我是这么称呼它的

 Call<List<OrdersModel>> allOrdersWuCo = apiInterfaceTwo.getAllOrdersWuCo();
    allOrdersWuCo.enqueue(new Callback<List<OrdersModel>>() {
        @Override
        public void onResponse(Call<List<OrdersModel>> call,Response<List<OrdersModel>> response) {
            List<OrdersModel> list = response.body();

        }

        @Override
        public void onFailure(Call<List<OrdersModel>> call,Throwable t) {
            String message = t.getMessage(); 
        }
    }); 

OrdersModel.java 这是我的订单模型类 我已经发布了一些订单模型类，因为它太大了：

public class OrdersModel {

Andorid Studio java.lang.IllegalStateException：预期为 BEGIN_ARRAY，但在第 1 行第 2 列路径 $ 处为 BEGIN_OBJECT

如何解决Andorid Studio java.lang.IllegalStateException：预期为 BEGIN_ARRAY，但在第 1 行第 2 列路径 $ 处为 BEGIN_OBJECT

我知道这不是关于此错误的第一个问题。我到处寻找答案，但找不到解决方案。当我运行代码时，我收到此异常；

Android：java.lang.NullPointerException：尝试在空对象引用上调用虚拟方法“ java.lang.String java.lang.Object.toString（）”

任何对解决方案的帮助将不胜感激。

编辑：

因此，在从数据库和与之交互的活动之间的代码来回浏览之后，我设法使其重新工作。以下是我按确切顺序执行的操作：

1. 我意识到我有一个日期字段没有接收任何数据，对此进行了纠正。
2. 清理了项目。
3. 重新启动Android Studio（基本上停止开发环境的所有操作）。
4. 从我的开发手机上卸载了该应用。
5. 重新启动android studio并重新安装该应用程序。
6. 我以某种方式工作= _ =，是的，这很神奇。

老实说，我不知道哪一步真正解决了它。我猜这是数据库中的日期字段在我没有收到任何数据的同时给我带来了麻烦。

答案1

您的阵列中ArrayAdapter至少包含一个条目null。那里不能有空值。

数组被填充，getDiaryDBDataList()所以问题也在那里。

API.java.lang.IllegalStateException：应为 BEGIN_OBJECT，但在第 1 行第 56 列处为 STRING

如何解决API.java.lang.IllegalStateException：应为 BEGIN_OBJECT，但在第 1 行第 56 列处为 STRING

JSON

{
    "status": "success","message": "User Registered Successfully","data": {
        "name": "pooja","mobile_no": "8211111111","email": "pooja@gmail.com","referal_id": null,"password": "$2y$10$AaleHI56","created_at": "2021-01-27T09:21:35.056380Z","updated_at": "2021-01-27T09:21:35.056411Z"
    }
}

我已经从 jsonschema2pojo 创建了类，并且已经多次验证 json 是否有效，但我仍然收到此错误

为上述 json 创建了两个类 - SignUpResponse、SignUpData

public interface RetrofitServicesSignUp {
    @FormUrlEncoded
    @POST("/api/passenger-register")
    Call<SignUpResponse> savePost(
            @Field("name") String name,@Field("mobile_no") String mobile_no,@Field("email") String email,@Field("password") String password,@Field("password_confirm") String password_confirm,@Field("referal_id") String referal_id,@Field("device_token") String device_token
   // @Field("device_token") String device_token
    );
}

主要活动是

protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.sign_up_layout);    
        mAPISignUpInterfaceService = ApiUtilsSignUp.getAPIService();
    
        username = edtUserName.getText().toString();
        password = edtPassword.getText().toString();
        phonestringValue = edtPhoneNumber.getText().toString();
        conPassword = edtConfirmPassword.getText().toString();
        email = edtEmail.getText().toString();
        referralcode = edtReferralCode.getText().toString();
          btnSignUp.setonClickListener(new View.OnClickListener() {
            public void onClick(View v) {
                boolean failFlag = false;
                stringPhoneNumberlength = edtPhoneNumber.getText().toString().length();   
         
 if (edtUserName.getText().toString().trim().length() == 0) {
                failFlag = true;
                edtUserName.setError("Fill name");
            }
                   //As above have done checking with empty field
                    if (failFlag == false) {
                        //none of the edit text is empty so good to go
                        sendPost(username,phonestringValue,email,password,conPassword,referralcode);
    
                    }
                }   
              
public void sendPost(String namee,String mobilenumberba,String emaill,String passwordd,String confirmpasswordd,String referalcodee ) {
                  mAPISignUpInterfaceService.savePost(namee,mobilenumberba,emaill,passwordd,confirmpasswordd,referalcodee,"abcdef").enqueue(new Callback<SignUpResponse>() {
                      @Override
                      public void onResponse(Call<SignUpResponse> call,Response<SignUpResponse> response) {
                      if(response.isSuccessful()) {
                          SignUpResponse jsonSignUpResponse = response.body();
                          Log.i(TAG,"Token from JsonResponse: " + jsonSignUpResponse.getStatus());
                          Log.i(TAG,"Token from JsonResponse: " + jsonSignUpResponse.getMessage());
                      }
                  }
                  @Override
                  public void onFailure(Call<SignUpResponse> call,Throwable t) {
                      Log.e(TAG,"Unable to submit post to API."+t.getCause());
                  }
              });
          }
    });
}

}

注册数据

   public class SignUpData {
        @Serializedname("name")
        @Expose
        private String name;
        @Serializedname("mobile_no")
        @Expose
        private String mobileNo;
        @Serializedname("email")
        @Expose
        private String email;
        @Serializedname("referal_id")
        @Expose
        private Object referalId;
        @Serializedname("password")
        @Expose
        private String password;
        @Serializedname("created_at")
        @Expose
        private String createdAt;
        @Serializedname("updated_at")
        @Expose
        private String updatedAt;
    
        public String getName() {
            return name;
        }
    
        public void setName(String name) {
            this.name = name;
        }
    
        public String getMobileNo() {
            return mobileNo;
        }
    
        public void setMobileNo(String mobileNo) {
            this.mobileNo = mobileNo;
        }
    
        public String getEmail() {
            return email;
        }
    
        public void setEmail(String email) {
            this.email = email;
        }
    
        public Object getReferalId() {
            return referalId;
        }
    
        public void setReferalId(Object referalId) {
            this.referalId = referalId;
        }
    
        public String getpassword() {
            return password;
        }
    
        public void setPassword(String password) {
            this.password = password;
        }
    
        public String getCreatedAt() {
            return createdAt;
        }
    
        public void setCreatedAt(String createdAt) {
            this.createdAt = createdAt;
        }
    
        public String getUpdatedAt() {
            return updatedAt;
        }
    
        public void setUpdatedAt(String updatedAt) {
            this.updatedAt = updatedAt;
        }
    
    }

注册响应

public class SignUpResponse {
    @Serializedname("status")
    @Expose
    private String status;
    @Serializedname("message")
    @Expose
    private String message;
    @Serializedname("data")
    @Expose
    private SignUpData data;
    public String getStatus() {
        return status;
    }
    public void setStatus(String status) {
        this.status = status;
    }
    public String getMessage() {
        return message;
    }
    public void setMessage(String message) {
        this.message = message;
    }
    public SignUpData getData() {
        return data;
    }
    public void setData(SignUpData data) {
        this.data = data;
    }
}

所以现在 json 是正确的，那么为什么会出现这个错误，我也参考了这个 "Expected BEGIN_OBJECT but was STRING at line 1 column 1" 并检查了 json 是否有效并在 android studio 中尝试了清理和重建选项
