Android 使用Volley解析嵌套JSON对象

我已经阅读了stack overflow中的大部分答案，并尝试了一些无效的答案

它是来自soapapi的响应

我试着用

JSONObject obj = new JSONObject(response);
JSONArray heroArray = new JSONArray();
JSONObject one = obj.getJSONObject("getProjectDetailsResult");
JSONObject two = one.getJSONObject("NewDataSet");
heroArray= two.getJSONArray("Rec");

for (int i = 0; i < heroArray.length(); i++) {
    JSONObject heroObject = heroArray.getJSONObject(i);
    Hero hero = new Hero(heroObject.getString("decProjectID"), 
heroObject.getString("chvProjectNameEng"));

我试过了

JSONObject heroArray = new JSONObject();
JSONObject one = obj.getJSONObject("getProjectDetailsResult");
JSONObject two = one.getJSONObject("NewDataSet");
heroArray= two.getJSONObject("Rec");

---

但我得到的其余代码的错误。我正在用来自

Rec

的样本测试这一点，它不是

JSONArray

，而是

JSONObject

。试用

try {
    JSONObject obj = new JSONObject(response);
    JSONObject one = obj.getJSONObject("getProjectDetailsResult");
    JSONObject two = one.getJSONObject("NewDataSet");

    if(two.get("Rec") instanceof JSONArray) {

        JSONArray heroArray = two.getJSONArray("Rec");

        for (int i = 0; i < heroArray.length(); i++) {

            JSONObject heroObject = heroArray.getJSONObject(i);

            Hero hero = new Hero(heroObject.getString("decProjectID"),
                heroObject.getString("intProjectSlNo"),
                heroObject.getString("chvProjectName"),
                heroObject.getString("chvProjectNameEng"),
                heroObject.getString("chrProjCatCode"),
                heroObject.getString("chvEngProjCategory"),
                heroObject.getString("nchvSecType"),
                heroObject.getString("chvEngSecType"),
                heroObject.getString("chvImplOfficerDesg"),
                heroObject.getString("chvImplOfficerDesgEng"),
                heroObject.getString("singleYrAmt"),
                heroObject.getString("TotExp"),
                heroObject.getString("percentage"));

            heroList.add(hero);
        }
    } else {
        JSONObject heroObject = two.getJSONObject("Rec");

        Hero hero = new Hero(heroObject.getString("decProjectID"),
            heroObject.getString("intProjectSlNo"),
            heroObject.getString("chvProjectName"),
            heroObject.getString("chvProjectNameEng"),
            heroObject.getString("chrProjCatCode"),
            heroObject.getString("chvEngProjCategory"),
            heroObject.getString("nchvSecType"),
            heroObject.getString("chvEngSecType"),
            heroObject.getString("chvImplOfficerDesg"),
            heroObject.getString("chvImplOfficerDesgEng"),
            heroObject.getString("singleYrAmt"),
            heroObject.getString("TotExp"),
            heroObject.getString("percentage"));

        heroList.add(hero);
    }
} catch ( Exception ex) {
    ex.printStackTrace();
}

试试看{
JSONObject obj=新的JSONObject（响应）；
JSONObject one=obj.getJSONObject（“getProjectDetailsResult”）；
JSONObject two=1.getJSONObject（“NewDataSet”）；
if（JSONArray的两个.get（“Rec”）实例）{
JSONArray heroArray=two.getJSONArray（“Rec”）；
for（int i=0；i

如何迭代对象？无需迭代。它是给u

Hero

，并且

Rec

中的属性不同。因此，您必须更新您的

Hero

模型。你能发布你的

Hero

模型吗？@JayanDev，你知道了吗？我试着用迭代器来做

try {
    JSONObject obj = new JSONObject(response);
    JSONObject one = obj.getJSONObject("getProjectDetailsResult");
    JSONObject two = one.getJSONObject("NewDataSet");

    if(two.get("Rec") instanceof JSONArray) {

        JSONArray heroArray = two.getJSONArray("Rec");

        for (int i = 0; i < heroArray.length(); i++) {

            JSONObject heroObject = heroArray.getJSONObject(i);

            Hero hero = new Hero(heroObject.getString("decProjectID"),
                heroObject.getString("intProjectSlNo"),
                heroObject.getString("chvProjectName"),
                heroObject.getString("chvProjectNameEng"),
                heroObject.getString("chrProjCatCode"),
                heroObject.getString("chvEngProjCategory"),
                heroObject.getString("nchvSecType"),
                heroObject.getString("chvEngSecType"),
                heroObject.getString("chvImplOfficerDesg"),
                heroObject.getString("chvImplOfficerDesgEng"),
                heroObject.getString("singleYrAmt"),
                heroObject.getString("TotExp"),
                heroObject.getString("percentage"));

            heroList.add(hero);
        }
    } else {
        JSONObject heroObject = two.getJSONObject("Rec");

        Hero hero = new Hero(heroObject.getString("decProjectID"),
            heroObject.getString("intProjectSlNo"),
            heroObject.getString("chvProjectName"),
            heroObject.getString("chvProjectNameEng"),
            heroObject.getString("chrProjCatCode"),
            heroObject.getString("chvEngProjCategory"),
            heroObject.getString("nchvSecType"),
            heroObject.getString("chvEngSecType"),
            heroObject.getString("chvImplOfficerDesg"),
            heroObject.getString("chvImplOfficerDesgEng"),
            heroObject.getString("singleYrAmt"),
            heroObject.getString("TotExp"),
            heroObject.getString("percentage"));

        heroList.add(hero);
    }
} catch ( Exception ex) {
    ex.printStackTrace();
}
