如何在SQLite数据库中存储嵌套的JSONArray值？ 从JSONArray获取值，它也存储在ArrayList中，工作正常。
我的JSONArray列表是，

我从服务器获得成功响应但不存储相关问题的ArrayList答案值。
我的Java代码是，
//Question
static String[] question_id;
static String[] question_type;
static String[] time_required;
static String[] question;
//Answer
static String[] answer_id;
static String[] answer;
static String[] correct;
//Question Array List
static List<String> arr_question_id = new ArrayList<String>();
static List<String> arr_question_type = new ArrayList<String>();
static List<String> arr_time_required = new ArrayList<String>();
static List<String> arr_question = new ArrayList<String>();
//Answer Array List
static List<String> arr_answer_id = new ArrayList<String>();
static List<String> arr_answer = new ArrayList<String>();
static List<String> arr_correct = new ArrayList<String>();
JsonObjectRequest jsonObjReq = new JsonObjectRequest(Request.Method.POST,
Url, params, new Response.Listener<JSONObject>() {
@Override
public void onResponse(JSONObject response) {
try {
// Parsing json object response
// response will be a json object
Boolean resultFlag = response.getBoolean("resultFlag");
if (resultFlag == true) {
String success = response.getString("successMessage");
JSONArray json_array_question = response.getJSONArray("Questions");
question_type = new String[json_array_question.length()];
time_required = new String[json_array_question.length()];
question_id = new String[json_array_question.length()];
question = new String[json_array_question.length()];
for (int i = 0; i < json_array_question.length(); i++) {
JSONObject json_object_question = json_array_question.getJSONObject(i);
question_type[i] = json_object_question.getString("questionType");
time_required[i] = json_object_question.getString("timeRequired");
question_id[i] = json_object_question.getString("questionID");
question[i] = json_object_question.getString("question");
JSONArray json_array_answer = json_object_question.getJSONArray("answer");
answer_id = new String[json_array_answer.length()];
answer = new String[json_array_answer.length()];
correct = new String[json_array_answer.length()];
for (int j = 0; j < json_array_answer.length(); j++) {
JSONObject json_object_answer = json_array_answer.getJSONObject(j);
answer_id[j] = json_object_answer.getString("ansID");
answer[j] = json_object_answer.getString("ans");
correct[j] = json_object_answer.getString("correct");
arr_answer_id.add(answer_id[j]);
arr_answer.add(answer[j]);
arr_correct.add(correct[j]);
}
arr_question_type.add(question_type[i]);
arr_time_required.add(time_required[i]);
arr_question_id.add(question_id[i]);
arr_question.add(question[i]);
}
*for (int i = 0; i < arr_question_id.size(); i++) {
item_solo_trivia.setQuestionType(arr_question_type.get(i));
item_solo_trivia.setTimeRequired(arr_time_required.get(i));
item_solo_trivia.setQuestionId(arr_question_id.get(i));
item_solo_trivia.setQuestion(arr_question.get(i));
for (j = 0; j < arr_answer_id.size(); j++) {
item_solo_trivia.setAnswerId(arr_answer_id.get(j));
item_solo_trivia.setAnswer(arr_answer.get(j));
item_solo_trivia.setCorrect(arr_correct.get(j));
}
}*
} else if (resultFlag == false) {
String error = response.getString("errorMessage");
Toast.makeText(activity.getApplicationContext(), error, Toast.LENGTH_SHORT).show();
}
} catch (JSONException e) {
e.printStackTrace();
Toast.makeText(activity,
"Error: " + e.getMessage(),
Toast.LENGTH_LONG).show();
}
hidepDialog();
}
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
Toast.makeText(activity,
error.getMessage(), Toast.LENGTH_SHORT).show();
// hide the progress dialog
hidepDialog();
}
});
// Adding request to request queue
AppController.getInstance().addToRequestQueue(jsonObjReq);
}
此代码出现问题，如何解决？
for (int i = 0; i < arr_question_id.size(); i++) {
item_solo_trivia.setQuestionType(arr_question_type.get(i));
item_solo_trivia.setTimeRequired(arr_time_required.get(i));
item_solo_trivia.setQuestionId(arr_question_id.get(i));
item_solo_trivia.setQuestion(arr_question.get(i));
for (j = 0; j < arr_answer_id.size(); j++) {
item_solo_trivia.setAnswerId(arr_answer_id.get(j));
item_solo_trivia.setAnswer(arr_answer.get(j));
item_solo_trivia.setCorrect(arr_correct.get(j));
}
}
表是，
//创建表
public static final String CREATE = "CREATE TABLE IF NOT EXISTS "
+ TABLE
+ " ( "
+ KEY_ID
+ "INTEGER AUTOINCREMENT,"
+ KEY_USER_ID
+ " text not null , "
+ KEY_QUESTION_TYPE
+ " text not null , "
+ KEY_QUESTION_ID
+ " text not null , "
+ KEY_QUESTION
+ " text not null , "
+ KEY_ANSWER_ID_1
+ " text not null , "
+ KEY_ANSWER_ID_2

+ KEY_ANSWER_ID_3
+ " text not null , "
+ KEY_ANSWER_ID_4

+ " text not null , "
+ KEY_CORRECT_2
+ " text not null , "
+ KEY_CORRECT_3

+ KEY_CORRECT_4 + " text not null" + ");";
如何将答案列表存储到SqliteDatabase中的相关问题？
请帮助我并建议我。
感谢。
