在改造中使用 GSON 解析 json 响应

Question

我已使用改造 sdk 进行 api 调用。我有 GSON sdk 用于解析响应。我有一些难以解析的 json 响应。我已经在下面发布了要解析的json响应。我需要获取地址行arraylist。

我正在从列表中获取空数据。

{
    "QA": {
        "CreditsUsed": 1,
        "State": "Results"
    },
    "SearchResult": {
        "VerifyLevel": "Verified",
        "Address": {
            "AddressLine": [{
                "LineContent": "None",
                "Label": {},
                "Line": "2500Kearney St"
            }, {
                "LineContent": "None",
                "Label": {},
                "Line": {}
            }, {
                "LineContent": "None",
                "Label": {},
                "Line": {}
            }, {
                "Label": "City name",
                "Line": "Springfield"
            }, {
                "Label": "State code",
                "Line": "MO"
            }, {
                "Label": {},
                "Line": "65803-5048"
            }, {
                "Label": "Country",
                "Line": "UNITED STATES OF AMERICA"
            }],
            "DPVStatus": "DPVNotConfigured"
        },
        "VerificationFlags": {
            "StateProvinceChanged": true,
            "PostCodeCorrected": true
        }
    }
}

请尝试以下 POJO，

地址

public class Address {

    @SerializedName("AddressLine")
    private List<AddressLine> addressLine = new ArrayList<AddressLine>();
    @SerializedName("DPVStatus")
    private String dPVStatus;

    /**
     * 
     * @return
     *     The addressLine
     */
    public List<AddressLine> getAddressLine() {
        return addressLine;
    }

    /**
     * 
     * @param addressLine
     *     The AddressLine
     */
    public void setAddressLine(List<AddressLine> addressLine) {
        this.addressLine = addressLine;
    }

    /**
     * 
     * @return
     *     The dPVStatus
     */
    public String getDPVStatus() {
        return dPVStatus;
    }

    /**
     * 
     * @param dPVStatus
     *     The DPVStatus
     */
    public void setDPVStatus(String dPVStatus) {
        this.dPVStatus = dPVStatus;
    }

}

    @SerializedName("LineContent")
    private String lineContent;
    @SerializedName("Label")
    private String label;
    @SerializedName("Line")

    public String getLine() {
        return line;
    }

    /**

     * @param line
     *     The Line
     */
    public void setLine(String line) {
        this.line = line;
    }

}

数据

    @SerializedName("QA")
    private QA qA;
    @SerializedName("SearchResult")
    private SearchResult searchResult;

    /**
     * 
     * @return
     *     The qA
     */  
    public QA getQA() {
        return qA;
    }

    /**
     * 
     * @param qA
     *     The QA
     */   
    public void setQA(QA qA) {
        this.qA = qA;
    }

    /**
     * 
     * @return
     *     The searchResult
     */   
    public SearchResult getSearchResult() {
        return searchResult;
    }

    /**
     * 
     * @param searchResult
     *     The SearchResult
     */   
    public void setSearchResult(SearchResult searchResult) {
        this.searchResult = searchResult;
    }

}

质量检查

public class QA {

    @SerializedName("CreditsUsed")
    private Long creditsUsed;
    @SerializedName("State")
    private String state;

    /**
     * 
     * @return
     *     The creditsUsed
     */
    public Long getCreditsUsed() {
        return creditsUsed;
    }

    /**
     * 
     * @param creditsUsed
     *     The CreditsUsed
     */   
    public void setCreditsUsed(Long creditsUsed) {
        this.creditsUsed = creditsUsed;
    }

    /**
     * 
     * @return
     *     The state
     */   
    public String getState() {
        return state;
    }

    /**
     * 
     * @param state
     *     The State
     */   
    public void setState(String state) {
        this.state = state;
    }

}

搜索结果

public class SearchResult {

    @SerializedName("VerifyLevel")
    private String verifyLevel;
    @SerializedName("Address")
    private Address address;
    @SerializedName("VerificationFlags")
    private VerificationFlags verificationFlags;

    /**
     * 
     * @return
     *     The verifyLevel
     */   
    public String getVerifyLevel() {
        return verifyLevel;
    }

    /**
     * 
     * @param verifyLevel
     *     The VerifyLevel
     */   
    public void setVerifyLevel(String verifyLevel) {
        this.verifyLevel = verifyLevel;
    }

    /**
     * 
     * @return
     *     The address
     */   
    public Address getAddress() {
        return address;
    }

    /**
     * 
     * @param address
     *     The Address
     */
    public void setAddress(Address address) {
        this.address = address;
    }

    /**
     * 
     * @return
     *     The verificationFlags
     */   
    public VerificationFlags getVerificationFlags() {
        return verificationFlags;
    }

    /**
     * 
     * @param verificationFlags
     *     The VerificationFlags
     */  
    public void setVerificationFlags(VerificationFlags verificationFlags) {
        this.verificationFlags = verificationFlags;
    }

}

验证标志

public class VerificationFlags {

    @SerializedName("StateProvinceChanged")
    private Boolean stateProvinceChanged;
    @SerializedName("PostCodeCorrected")
    private Boolean postCodeCorrected;

    /**
     * 
     * @return
     *     The stateProvinceChanged
     */   
    public Boolean getStateProvinceChanged() {
        return stateProvinceChanged;
    }

    /**
     * 
     * @param stateProvinceChanged
     *     The StateProvinceChanged
     */   
    public void setStateProvinceChanged(Boolean stateProvinceChanged) {
        this.stateProvinceChanged = stateProvinceChanged;
    }

    /**
     * 
     * @return
     *     The postCodeCorrected
     */   
    public Boolean getPostCodeCorrected() {
        return postCodeCorrected;
    }

    /**
     * 
     * @param postCodeCorrected
     *     The PostCodeCorrected
     */  
    public void setPostCodeCorrected(Boolean postCodeCorrected) {
        this.postCodeCorrected = postCodeCorrected;
    }

}

改造电话

RetrofitRest.getClient().getLogin("your text", obj, new Callback<Data>() {
            @Override
            public void success(Data data, Response response) {
                SearchResult searchResult = data.getSearchResult();
                if (searchResult != null) {
                    Address address = searchResult.getAddress();
                    if (address != null && address.getAddressLine() != null) {
                        for (AddressLine addressLine : address.getAddressLine()) {
                            Log.d("TAG", "addressLine" + addressLine);
                        }
                    }
                }
            }
        });

我已经纠正了它有多余“，”的json，如下所示。

"StateTransition":"SearchResults",

在解析 http://www.jsoneditoronline.org/ 中的 json 时。我注意到在您的 jsonObject 中，您还有 2 个带有键“CAB”和“Result”的 jsonObject。在您的第二个 jsonObject 中，您有另一个带有“Address”键的 jsonObject，其中有“AddressLine”数组。

所以请纠正完整的 pojo DineshValues。 如果您需要任何进一步的帮助，请告诉我，我将添加完整的 POJO

更新
解决方案 1 -
正如评论中提到的，您使用 jsonschema2pojo 生成 pojo，您可以保留那些可能只是代码的类并使用以下行来提取地址

List<AddressLine> addressLine = arg0.getResult().getAddress().getAddressLine()

现在迭代 addressLine 并提取您需要的数据。

注意 - 1) 确保 arg0 是根 JsonObject 的类型类。
2) cricket_007 提到的另一点 - 每个标签和线 属性不是字符串，它们是对象，如 {} 所述。

解决方案 2 -
您只能在项目中保留生成的类文件中的 AddressLine 类，并使用以下行来提取地址。

RetrofitRest.getClient().getLogin("1111111" ,obj,new Callback<DineshValues >() {

  @Override
        public void success(String arg0, Response arg1) {
            // TODO Auto-generated method stub
            JsonObject rootJsonObject = new JsonObject(arg0);
            JsonObject searchResultJsonObject = rootJsonObject.getJsonObject("SearchResult");
            JsonObject addressJsonObject = searchResultJsonObject.getJsonObject("Address")

            Type listType = new TypeToken<List<AddressLine>>(){}.getType();
            List<AddressLine> addressLineList = gson.fromJson(addressJsonObject, listType);
            //Now iterate the addressLineList to get the address
             Log.e("size",addressLineList.getSize+"");

        }
}
