}
}
data form table is:
information_id: 6
language_id: 1
title: Hot News
description: <p> Delivery Information</p>
But i need Delivery Information only for show in Toast
my toast text is "<p> Delivery Information</p>"
You could create a function to strip html tags, something like :
public String stripHtml(String html) {
return Html.fromHtml(html).toString();
}
Output the returned string in the toast

I am trying to make an ArrayList of objects .But the logd at the last is always showing an empty ArrayList.How can I do it.With the present code I tried few things but they didn't work.I guess i have to return the ArrayList but I am confused.
This is my code in MainActivity.java

for (int i = 0; i < 10; i++) {
JSONObject news = articles.getJSONObject(i);
title = news.getString("title");
img_url = news.getString("image");

Thank you for reading the codes!
Your toast message is taken from 'url_String'.
The 'url_String' is updated when 'onOkHttpResponse()' is triggered.
The 'onOkHttpResponse()' is called when 'Set_Content_to_NewsList()' is triggered.
The 'Set_Content_to_NewsList()' is triggered 5 times.
The toast message will always get the latest 'url_String' and not from any other rows.
A quick fix would be to store each 'url_String' in an array, and using 'position' as an index to this array.
I'm new to JSON parsing. This code works. But how I can access directly to "likes" and "webformatURL" if there were not "totalHits" and "hits" on JSON array?
private void parseJSON() {
String url="https://pixabay.com/api/?key=8947271-cb39739eaa5835e1eaa2f53c6&q=yellow+flowers&image_type=photo&pretty=true";
JsonObjectRequest request = new JsonObjectRequest(
Request.Method.GET,
url,
null,
new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
try {
JSONArray jsonArray = response.getJSONArray("hits");
for (int i = 0; i < jsonArray.length(); i++){
JSONObject hit = jsonArray.getJSONObject(i);
String imageUrl = hit.getString("webformatURL");
int likeCount = hit.getInt("likes");
mExampleList.add(new ExampleItem(imageUrl, likeCount));
}
mExampleAdapter = new ExampleAdapter(MainActivity.this, mExampleList);
mRecyclerView.setAdapter(mExampleAdapter);
} catch (JSONException e) {
e.printStackTrace();
}
}
},
new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
error.printStackTrace();
}
}
);
}
You can use Google Gson library to parse your json to directly ArrayList object.
You can do this.
JsonArray itemArray = new JsonArray(response);
Type listType = new TypeToken<List<Model>>() {
}.getType();
List<Model> yourList = new Gson().fromJson(itemArray, listType);
for (Model model : yourList) {
// use this list
System.out.println(model.toString());
}
Here is your model class.
class Model {
private int id;
private String title;
private long date_add;
private String poster;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
public long getDate_add() {
return date_add;
}
public void setDate_add(long date_add) {
this.date_add = date_add;
}
public String getPoster() {
return poster;
}
public void setPoster(String poster) {
this.poster = poster;
}
#Override
public String toString() {
return "Model{" +
"id=" + id +
", title='" + title + '\'' +
", date_add=" + date_add +
", poster='" + poster + '\'' +
'}';
}
}
To add Gson to your project. Just add this dependency in your build.gradle
dependencies {
compile 'com.google.code.gson:gson:2.8.4'
}

Error : Json parsing error: Value [{"elements":[{"distance":{"text":"1 m","value":0},"duration":{"text":"1 min","value":0},"status":"OK"}]}] at rows of type org.json.JSONArray cannot be converted to JSONObject
How do I get access to rows -> elements -> distance -> text ?
Thanks.
JSONObject contacts = jsonObj.getJSONObject("rows");
The Key "rows" returns an array and not an Object.
Change the above statement to
JSONArray rowArray = jsonObj.getJSONArray("rows");
Now select the first element in rowArray array
JSONObject firstRow = rowArray.getJSONObject(0);
From this object obtain the array associated with elements key
JSONArray elementArray = firstRow.getJSONArray("elements");
Then,
JSONObject firstElement = elementArray.getJSONObject(0);
JSONObject distance = firstElement.getJSONObject("distance");
String text = distance.getString("text");
My new code :
if (jsonStr != null) {
try {
JSONObject object = new JSONObject(jsonStr);
JSONArray rows = object.getJSONArray("rows");
JSONArray elements = rows.getJSONArray("elements");
JSONObject distance = elements.getJSONObject("distance");
test58 = distance.getString("text");
}
error with rows.getJSONArray("elements") and elements.getJSONObject("distance")
getJsonArray (int) in JsonArray cannot be applied to (java.lang.string)
this is idea #Override
#Override
protected Void doInBackground(Void... params) {
System.out.println("Menu doInBackground");
ParseJson parseJson = new ParseJson();
JSONObject jsonObject = parseJson.getJsonFromURL("YOUR LINK");
try {
JSONArray jsonArray = jsonObject.getJSONArray("rows");
for (int i = 0; i < jsonArray.length(); i++) {
JSONObject jsonObjectRow = jsonArray.getJSONObject(i);
for(int j= 0; j< jsonObjectRow; j++){
JSONObject jsonObjectElements = jsonArray.getJSONObject(j);
....
for(int k = 0; k< jsonObjectElements; k++){
JSONObject jsonObjectDistance = jsonArray.getJSONObject(j);
...
}
}

UPDATE: I found usage of date2 (the real name of variable, not data2 as you menthioned in description).
All you need is to sort your List<Calenndar_Model>:
private void caladata() {
// showing refresh animation before making http call
swipeRefreshLayout.setRefreshing(false);
// Volley's json array request object
StringRequest stringRequest = new StringRequest(Request.Method.POST, CALENDAR_DATA,
new Response.Listener < String > () {
#Override
public void onResponse(String response) {
// Log.d(TAG, response.toString());
// hidePDialog();
JSONObject object = null;
try {
object = new JSONObject(response);
} catch (JSONException e) {
e.printStackTrace();
}
JSONArray jsonarray = null;
try {
jsonarray = object.getJSONArray("Table");
} catch (JSONException e) {
e.printStackTrace();
}
calList = new ArrayList<>();
for (int i = 0; i < jsonarray.length(); i++) {
try {
JSONObject obj = jsonarray.getJSONObject(i);
Calenndar_Model movie = new Calenndar_Model();
movie.setUserid(obj.getString("userid"));
movie.setHost(obj.getString("eventname"));
String str = obj.getString("eventdate").replaceAll("\\D+","");
String upToNCharacters = str.substring(0, Math.min(str.length(), 13));
DateFormat timeZoneFormat = new SimpleDateFormat("dd-MM-yyyy HH:mm:ss");
timeZoneFormat.setTimeZone(TimeZone.getTimeZone("GMT-8"));
Date time = new Date(Long.parseLong(upToNCharacters));
//System.out.println(time);
movie.setDate(String.valueOf(timeZoneFormat.format(time)));
movie.setColor(obj.getString("eventcolor"));
movie.setAutoid(obj.getString("autoid"));
//Toast.makeText(getApplicationContext(), "server data respone", Toast.LENGTH_LONG).show();
calList.add(movie);
} catch (JSONException e) {
// Log.e(TAG, "JSON Parsing error: " + e.getMessage());
}
}
//sort calList list
Comparator<Calenndar_Model> calendarModelComparator = new Comparator<Calenndar_Model>() {
#Override
public int compare(Calenndar_Model cm1, Calenndar_Model cm2) {
boolean firstContainsData2 = calendarModelContainsData2(cm1);
boolean secondContainsData2 = calendarModelContainsData2(cm2);
if (firstContainsData2 && secondContainsData2) {
return 0;
} else if (firstContainsData2) {
return -1;
} else if (secondContainsData2) {
return 1;
} else return cm2.getData().compareTo(cm1.getData());
}
private boolean calendarModelContainsData2(Calenndar_Model cm) {
return cm.getData().contains(data2);
}
};
Collections.sort(calList, calendarModelComparator);
// notifying list adapter about data changes
// so that it renders the list view with updated data
adapter.swapList(calList);
//listView.smoothScrollToPositionFromTop(selectedPos,0,300);
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
// VolleyLog.d(TAG, "Error: " + error.getMessage());
// hidePDialog();
}
}) {
#Override
protected Map < String, String > getParams() {
Map < String, String > params = new HashMap < String, String > ();
params.put("clientid", get1);
return params;
}
};
// Adding request to request queue
MyApplication.getInstance().addToRequestQueue(stringRequest);
}
Suppose date2 is eventname you want to compare.
if(date2.equals(movie.getHost())
{
// store Movie object on index 0, if it equals date2
calList.add(0, movie);
}
else
{
calList.add(movie);
}
Remove the Following Lines from caladata().
int index=calList.indexOf(date2);
calList.add(movie);
calList.remove(date2);
calList.add(0, movie);
