Android Can'；无法检索具有子数组多个键值的JSON对象

我对安卓非常陌生。请帮助我获取下面引用的JSON文件中的所有数据。我能够获取每个JSON对象的JSON，但无法获取标记对象及其内部数组和键值。
多谢各位

{
    "error": false,
    "terms": [{
        "TermId": "1",
        "TermTitle": "Term1"
    }, {
        "TermId": "2",
        "TermTitle": "Term2"
    }, {
        "TermId": "3",
        "TermTitle": "Term3"
    }],
    "exams": [{
        "TypeId": "1",
        "TypeTitle": "Unit Test"
    }, {
        "TypeId": "2",
        "TypeTitle": "PERIODIC TEST 1"
    }, {
        "TypeId": "3",
        "TypeTitle": "PERIODIC TEST 2"
    }, {
        "TypeId": "4",
        "TypeTitle": "HALF YEARLY EXAM"

请使用此命令获取所有内部JsonArray

JSONObject jsonObject = null;
    try {
        jsonObject = new JSONObject(response);  //Response is your Json Response
        //Getting "error" tag
        Boolean error = jsonObject.getBoolean("error");
        //Getting "terms" JsonArray
        for (int i = 0; i < jsonObject.getJSONArray("terms").length(); i++) {
            JSONObject jsonObject1 = jsonObject.getJSONArray("terms").getJSONObject(i);
            String termId = jsonObject1.getString("TermId");  //Get Term id According to index
            String TermTitle = jsonObject1.getString("TermTitle");  //Get Term Title According to index

        }

        //Getting "exams" JsonArray
        for (int i = 0; i < jsonObject.getJSONArray("exams").length(); i++) {
            JSONObject jsonObject1 = jsonObject.getJSONArray("terms").getJSONObject(i);
            String termId = jsonObject1.getString("TermId");  //Get Term id According to index
            String TermTitle = jsonObject1.getString("TermTitle");  //Get Term Title According to index

        }
        //Getting "status" tag
        int status = jsonObject.getInt("status");

        //Getting "examname" tag
        String  examname = jsonObject.getJSONObject("exam").getString("examname");

        //Getting "marks" Json Object
        JSONObject marksJsonObject = jsonObject.getJSONObject("marks");
        //Getting "exams" JsonArray
        for (int i = 0; i < marksJsonObject.getJSONObject("Language 1 English").getJSONArray("Theory").length(); i++) {
            //JSONObject jsonObject1 = marksJsonObject.getJSONObject("Language 1 English").getJSONArray("Theory").get(i);
            String values = (String) marksJsonObject.getJSONObject("Language 1 English").getJSONArray("Theory").get(i);  //Get each Value According to index

        }

        for (int i = 0; i < marksJsonObject.getJSONObject("Language 2 Malayalam").getJSONArray("Theory").length(); i++) {
            //JSONObject jsonObject1 = marksJsonObject.getJSONObject("Language 1 English").getJSONArray("Theory").get(i);
            String values = (String) marksJsonObject.getJSONObject("Language 2 Malayalam").getJSONArray("Theory").get(i);  //Get each Value According to index

        }

        for (int i = 0; i < marksJsonObject.getJSONObject("Language 3 Hindi").getJSONArray("Theory").length(); i++) {
            //JSONObject jsonObject1 = marksJsonObject.getJSONObject("Language 1 English").getJSONArray("Theory").get(i);
            String values = (String) marksJsonObject.getJSONObject("Language 3 Hindi").getJSONArray("Theory").get(i);  //Get each Value According to index

        }

        for (int i = 0; i < marksJsonObject.getJSONObject("Mathematics").getJSONArray("Theory").length(); i++) {
            //JSONObject jsonObject1 = marksJsonObject.getJSONObject("Language 1 English").getJSONArray("Theory").get(i);
            String values = (String) marksJsonObject.getJSONObject("Mathematics").getJSONArray("Theory").get(i);  //Get each Value According to index

        }

        for (int i = 0; i < marksJsonObject.getJSONObject("EVS").getJSONArray("Theory").length(); i++) {
            //JSONObject jsonObject1 = marksJsonObject.getJSONObject("Language 1 English").getJSONArray("Theory").get(i);
            String values = (String) marksJsonObject.getJSONObject("EVS").getJSONArray("Theory").get(i);  //Get each Value According to index

        }

        for (int i = 0; i < marksJsonObject.getJSONObject("Computer").getJSONArray("Theory").length(); i++) {
            //JSONObject jsonObject1 = marksJsonObject.getJSONObject("Language 1 English").getJSONArray("Theory").get(i);
            String values = (String) marksJsonObject.getJSONObject("Computer").getJSONArray("Theory").get(i);  //Get each Value According to index

        }

        for (int i = 0; i < marksJsonObject.getJSONObject("Arabic").getJSONArray("Theory").length(); i++) {
            //JSONObject jsonObject1 = marksJsonObject.getJSONObject("Language 1 English").getJSONArray("Theory").get(i);
            String values = (String) marksJsonObject.getJSONObject("Arabic").getJSONArray("Theory").get(i);  //Get each Value According to index

        }

    } catch (JSONException e) {
        e.printStackTrace();
    }

JSONObject JSONObject=null；
试一试{
jsonObject=newJSONObject（response）；//response是您的Json响应
//获取“错误”标记
Boolean error=jsonObject.getBoolean（“错误”）；
//获取“术语”JsonArray
for（int i=0；i

共享您现有的代码进程可能与我的代码中的terms数组重复。但是您可以这样做，并根据您的要求获取所有数组和对象。无法检索mark对象和其他数组对象。Term对象和Examies对象已被获取。等待，我将执行此操作。
