Convert the Json string to Hashmap like below using Google's Gson, then you can interate through the hashmap
String jsonString = "Your JSON string";
HashMap<String, JsonObject> map = new Gson().fromJson(jsonString, new TypeToken<HashMap<String, JsonObject>>(){}.getType());

I need to include the list of US states and state counties locally in the application am working on. So can someone please let me know where can I find that list to download either in Json or .plist format.
Thanks

You can do whatever you want if you put your mind to it.
I've written you a tool to extract this data from a known updated source (Wikipedia).
The code can be downloaded from Github.
using System;
using System.Collections.Generic;
using System.IO;
using System.Net.Http;
using HtmlAgilityPack;
using Newtonsoft.Json;
namespace GetCitiesCounties
{
class Program
{
static void Main(string[] args)
{
Console.WriteLine(#"Hitting Wikipedia");
var uri = new Uri("https://en.wikipedia.org/wiki/List_of_United_States_counties_and_county_equivalents");
var client = new HttpClient();
var rs = client.GetAsync(uri).Result;
if (rs.IsSuccessStatusCode)
{
var htmlContent = rs.Content.ReadAsStringAsync().Result;
var htmlDoc = new HtmlDocument();
htmlDoc.LoadHtml(htmlContent);
var list = new List<dynamic>();
var nodes = htmlDoc.DocumentNode.SelectNodes("//table[#class='wikitable sortable']//tr");
Console.WriteLine(#"Processing Rows");
int rowIndex = 0;
foreach (var row in nodes)
{
if (rowIndex++ > 0)
{
var county = row.SelectNodes("td")[1].InnerText;
var state = row.SelectNodes("td")[2].InnerText;
list.Add(new
{
County = county,
State = state
});
}
}
var json = JsonConvert.SerializeObject(list);
File.WriteAllText(#"C:\test.json", json);
Console.WriteLine(#"Done, extracted cities and states to json file C:\test.json");
Console.ReadLine();
}
}
}
}
This is a snippet of the result. It shows each county in the US and the state it's attached to.
[
{
"County": "Autauga County",
"State": "Alabama"
},
{
"County": "Baldwin County",
"State": "Alabama"
},
{
"County": "Barbour County",
"State": "Alabama"
}
]

You can find list here : https://www.webtoolz.online/resources/usa-list-of-states
This list contains state names and abbreviations in JSON format.

this is my json response

"message": "Success",
"data": {
"id": "14"
}
}
how to read this values

You can use the help of Google's GSON library built for exact your pupose.
YourPojoClass model = new Gson().fromJson(jsonResponse, YourPojoClass.class);
Convert your json to PojoModel by using jsonschema2pojo.org

You can do it like this:
Create a JSONObject:
JSONObject jObject = new JSONObject(result);
To get a specific boolean
String aJsonString = jObject.getBoolean("status");
To get a specific String
String aJsonString = jObject.getString("message");
To get a specific Integer
int aJsonInteger = jObject.getInt("code");

How to filtering data for two values in FirebaseListAdapter? [duplicate]

Query based on multiple where clauses in Firebase

Closed 5 years ago.
I am use Firebase DB and FirebaseListAdapter for display and filtering my data. But, my data is filtering for ONE values (idUser). But, i want filtering data for TWO values idUser and good (show data where idUser=2 and good=true).
Can i try it in android?
firebaseListAdapter = new FirebaseListAdapter<Movie>(this, Movie.class,
R.layout.item_movie, FirebaseDatabase.getInstance().getReference()
.child("movies")
.orderByChild("idUser")
.equalTo("2"))
My database:
{
"movies": {
"1": {
"name": "comedy",
"idUser": "2",
"good": "true"
},
"2": {
"name": "Horror",
"idUser": "2",
"good": "false"
},
"3": {
"name": "comedy",
"idUser": "2",
"good": "true"
}
}
}

You can only use order by once.
So the answer is to modify your schema.

How to get string from multiple json array inside a json object [duplicate]

"calendar":

{

}
]
}
}
Could any one please help me how to get date from json array string

Your json should be like this
{
"data": {
"calendar": [
{
"Booked": [
"13-11-2015",
"12-12-2015"
],
"Available": [
"20-12-2015",
"22-12-2015"
]
}
]
}
}
You can use json online parser to check the validity of a json.
Now, coming back to your actual question.I dont have an android IDE so I will post a quick code to give u an idea
JSONObject jparentobj= new JSONObect("jsonString");
JSONObject datajObj= jparentobj.getJSONObect("data");
JSONArray calenderarray = datajObj.getJSONArray{"calender");
for (int i = 0; i < calenderarray.size(0); i++){
String booked = calenderarray.get(i).getString("Booked");
//Like this get each entity
}
Hope this helps you..
