org.json.JSONException: значение в org.json.JSON.typeMismatch
Я анализирую некоторые данные по ссылке, которая содержит список таблицы премьер-лиги. Мне нравится использовать его, чтобы показать в виде списка. Но я получаю ошибки JSONException и JSON.typeMismatch.
Ниже мой код:
public class ParseJSON {
public static String[] position1;
public static String[] team;
public static String[] points;
public static final String JSON_ARRAY = "data";
public static final String CHILD_ARRAY = "standings";
public static final String CHILDS_CHILD_ARRAY = "overall";
public static final String KEY_POSITION = "position";
public static final String KEY_TEAM = "team";
public static final String KEY_POINTS = "points";
private JSONArray users = null, user2=null;
private String json;
public ParseJSON(String json){
this.json = json;
}
protected void parseJSON(){
JSONObject jsonObject=null, jsonObject1=null;
try {
jsonObject = new JSONObject(json);
users = jsonObject.getJSONArray(JSON_ARRAY);
try {
jsonObject1=new JSONObject(json);
user2=jsonObject1.getJSONArray(CHILD_ARRAY);
position1 = new String[user2.length()];
team = new String[user2.length()];
for(int i=0;i<user2.length();i++){
JSONObject jo = user2.getJSONObject(i);
position1[i] = jo.getString(KEY_POSITION);
team[i] = jo.getString(KEY_TEAM);
/*points[i] = jo.getString(KEY_POINTS);*/
}
}catch (JSONException e) {
e.printStackTrace();
}
points = new String[users.length()];
} catch (JSONException e) {
e.printStackTrace();
}}}
Я получаю сообщение об ошибке

Может кто-нибудь, пожалуйста, направьте меня, где я делаю неправильно? Этот формат JSON, как анализировать и отображать:

Решение
Я нашел решение.
Класс анализатора JSON:
public class ParseJSON {
public static String[] position1;
public static String[] team;
public static String[] points;
public static final String JSON_ARRAY = "data";
public static final String CHILD_ARRAY = "standings";
public static final String KEY_ID = "position";
public static final String KEY_NAME = "team";
private JSONObject users = null;
private JSONArray user2=null;
private JSONObject user3=null;
private String json;
public ParseJSON(String json){
this.json = json;
}
protected void parseJSON() {
JSONObject jsonObject = null;
try {
jsonObject = new JSONObject(json);
users = jsonObject.getJSONObject(JSON_ARRAY);
try {
user2=users.getJSONArray(CHILD_ARRAY);
position1 = new String[user2.length()];
team = new String[user2.length()];
points=new String[user2.length()];
for (int i = 0; i < user2.length(); i++) {
JSONObject jo = user2.getJSONObject(i);
try {
user3=jo.getJSONObject("overall");
points[i] = user3.getString("points");
System.out.println("Message me: "+points[i]);
}catch (Exception e)
{
e.printStackTrace();
}
position1[i] = jo.getString(KEY_ID);
team[i] = jo.getString(KEY_NAME);
System.out.println("Message me: "+position1[i]);
System.out.println("Message me: "+team[i]);
}
}catch (Exception e)
{
e.printStackTrace();
}
} catch (JSONException e) {
e.printStackTrace();
}
}
}
Вы всегда будете получать ошибку, потому что "данные" - это JSONObject, а не JSONArray
users = jsonObject.getJSONArray (JSON_ARRAY);
ваш JSON, где данные JSONObject
{
"data":{
"standings":[
{
"identifier":"5hichhljwlipyqvghhr0banvd2gehtcf",
"position":1,
"team_identifier":"akppwaoizlxbsa66oupfkawevutbnjxp",
"tea
Сразу после jsonObject = new JSONObject(json); у вас есть объект JSON data а не массив JSON. Так что попробуйте это
jsonObject = new JSONObject(json);
JSONObject standings = jsonObject.getJSONObject("data");
//Continue with the code
Вы берете JSONObject в JSONArray, что неправильно.
users = jsonObject.getJSONArray(JSON_ARRAY);
измените тип данных ваших пользователей с JSONArray на JSONObject и обновите приведенную выше строку следующим образом:
users = jsonObject.getJSONObject(JSON_ARRAY);
Я должен изменить код. пожалуйста следуйте за этим.
public class ParseJSON {
public static String[] position1;
public static String[] team;
public static String[] points;
public static final String JSON_OBJECT_DATA = "data";
public static final String CHILD_ARRAY = "standings";
public static final String CHILDS_CHILD_ARRAY = "overall";
public static final String KEY_ID = "position";
public static final String KEY_NAME = "team";
public static final String KEY_EMAIL = "points";
private JSONObject users = null;
private JSONArray user2=null;
private String json;
public ParseJSON(String json){
this.json = json;
}
protected void parseJSON(){
JSONObject jsonObject=null, jsonObject1=null;
try {
jsonObject = new JSONObject(json);
users = jsonObject.getJSONObject(JSON_OBJECT_DATA);
try {
user2=users.getJSONArray(CHILD_ARRAY);
position1 = new String[user2.length()];
team = new String[user2.length()];
for(int i=0;i<user2.length();i++){
JSONObject jo = user2.getJSONObject(i);
position1[i] = jo.getString(KEY_ID);
team[i] = jo.getString(KEY_NAME);
/*points[i] = jo.getString(KEY_EMAIL);*/
}
}catch (JSONException e) {
e.printStackTrace();
}
points = new String[users.length()];
} catch (JSONException e) {
e.printStackTrace();
}}}
