使用 Gson 解析 json 数组

Question

i have the following Json Response as :

{"StatusCode":2,"Error_fields":[{"user":"XXX"},{"password":"YYY"}]}, and i have to parse that response using Gson, so i have built the ResponseBase class as following :

BaseResponse.java

    @SerializedName("StatusCode")
    private int StatusCode;

    @SerializedName("Error_fields")
    List<ErrorField> Erro;

    public void setStatusCode(int statusCode){
        this.StatusCode=statusCode;
    }

    public int getStatusCode(){
        return this.StatusCode;
    }

    public List <ErrorField> getErro() {
        return Erro;
    }

    public void setErro(List <ErrorField> erro) {
        Erro = erro;
    }

and Also i have added the Error Fields as : ErrorField.java

public class ErrorField {

    String ErrorTitle;

    String ErrorMessage;

    public String getErrorTitle() {
        return ErrorTitle;
    }

    public void setErrorTitle(String errorTitle) {
        ErrorTitle = errorTitle;
    }

    public String getErrorMessage() {
        return ErrorMessage;
    }

    public void setErrorMessage(String errorMessage) {
        ErrorMessage = errorMessage;
    }
}

so in order , to receive the json array correctly , i have to add annotation to ErrorTitle to be :

@SerializedName("password")
    String ErrorTitle;

so in case of i don't know the returned json object key's it will fail , and it's not a good solution to add all the suggested annotation to expect is it existed or not , also i have tried to make that List<ErrorField> as List<JsonObject> and the same results it returns empty value , but it counts "2" as the Array size !?

Answer 1

problem solved by changing the List<ErroField> into

List<Map<String,String>> Errro;

and it's working with a dynamic range of returned json objects without depend on the key's
