Question

我对Android非常陌生。请帮助我将所有数据都放在下面引用的JSON文件中。我能够获得每个JSON对象的JSON，但不能获得标记对象及其内部数组及其键值。
谢谢。

{
    "error": false,
    "terms": [{
        "TermId": "1",
        "TermTitle": "Term1"
    }, {

请用它来获取所有内部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();
    }
