Unable to link URL from ListView in Android

Hello I am trying to click ListView and Open URL from the ListView.
I could set the URL addresses using setter methods on the ListView, however when I try to display the URLs using Toast messages, it shows different URL.
I use for loop for adding multiple items on ListView news_ListView
If you have any suggestions, please help me out.

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.

How to parse JSON data without array name?

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'
}

How to Change order of List view's Items according to some Specific input

I want to change the sequence of my list view's items according to a specific input string which is matches with any of list view items contents and that item comes on the top of list view. I have tried hard but getting no success till now.if any other query please ask.
Here is the code for fetching data from server:
Here date2 is string input which I'm trying to compare

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();
int index=calList.indexOf(date2);
calList.add(movie);
calList.remove(date2);
calList.add(0, movie);
} catch (JSONException e) {

title.setText(movieList.get(position).getHost());
date1.setText(movieList.get(position).getDate());
return convertView;
}
}
Model Class:
public class Calenndar_Model {

}
public void setDate(String date) {
this.date = date;
}
public String getUserid() {
return userid;
}
public void setUserid(String userid) {
this.userid = userid;
}
public String getColor() {
return color;
}
public void setColor(String color) {
this.color = color;
}
public String getAutoid() {
return autoid;
}
public void setAutoid(String autoid) {
this.autoid = autoid;
}
}

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);

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&gt"

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

Its better to create Model class and then you can parse the response with gson.
For example,
Imagine that you have your response with two strings Name and Mail. Create a model with two strings.
public class Sample{
public Sample()
{
}
#SerializedName("Name")//if needed
String name;
#SerializedName("Email")//if needed
String email;
public void set(String name) {
this.name = name;
}
public String getName() {
return name;
}
public void set(String email) {
this.email = email;
}
public String getEmail() {
return email;
}
}
Then parse your response with gson.
Sample sample = gson.fromJson(jsonRes.toString(), Sample.class);
Then you can access the members of the object sample. Change the Sample class as you needed(with the array of strings and int. You can use ArrayList instead of Array)

String[] city= {};
String[] id= {};
JSONArray jsonDetailsObj = json.getJSONArray("cityList");
JSONObject jsonLoop = null;
int noOfPoints = jsonDetailsObj.length();
city= new String[noOfPoints];
id= new String[noOfPoints];
for (int i=0 ; i < noOfPoints ; i++)
{
jsonLoop=jsonDetailsObj.getJSONObject(i);
city [i] = jsonLoop.getString("CityName");
id[i] = jsonLoop.getString("ID");
}
