Unable to fetch json data

Question

My server json data is like:--[]

public class Main2Activity extends Activity {
        final Context context = this;

        }

        @Override
        protected void onCreate(Bundle savedInstanceState) {

        }
    }

Here I can Fetch all the country name.but Rank is not coming on text-view.where is the problem??can anyone tell me????????

You are using wrong key for rank so replace this line : txt1.setText("Rank- "+jsonObject.getString("Rank")); — Haresh Chhelana, Aug 23 '14 at 04:40

You are using wrong key 'name'

txt1.setText("Rank- "+jsonObject.getString("name"));

Use this line

txt1.setText("Rank- "+jsonObject.getString("Rank"));

You have to create listener for getting item selected event of spinner.

Refer this link and check for code in setOnItemClickListener()

Add comment if you find some difficulty.

Try to replace this code :

txt1.setText("Rank- "+jsonObject.getString("name"));

With this code :

 txt1.setText("Rank- "+jsonObject.getString("Rank"));

Note : you have given wrong key reference to get Rank value

you store rank value in hashmap with name as key and selected spinner value use as hashmap key then try to show rank value from hashmap spinner value as key – Haresh Chhelana Aug 23 '14 at 04:56

First add to your List where you are parse your data

nameList.add(jsonObject.getString("Rank"));

You are using wrong key 'name'

txt1.setText("Rank- "+jsonObject.getString("name"));

Use this line onItemSelectedListener of Spinner.

txt1.setText("Rank- "+nameList.get(position).get("Rank"));

Change here:

 for (int i = 0; i < jsonArray.length(); i++) {
       JSONObject jsonObject = jsonArray.getJSONObject(i);
       nameList.add(jsonObject.getString("name"));
       nameList.add(jsonObject.getString("Rank"));

  }

Can You please suggest Where I have to put public void onItemSelected(AdapterView> parent, View view, int pos, long id) {} in my program???I cant understand – user_apr Aug 23 '14 at 05:02
After populated your data in spinner. where you set your arraylist to your adapter. in onCreate() method. – Piyush Aug 23 '14 at 05:04
I have added ..But still showing error in nameList and position ..Can I send you the code?? – user_apr Aug 23 '14 at 05:23
Make this List nameList = new ArrayList(); global varibale. And in your spinner onItemSelectedListener method there is one int varibale so you have to pass that instead of position. – Piyush Aug 23 '14 at 05:24

Try this:

int cnt= jsonarr.length();
String country_name;
String country_rank;                    

for(int i=0;i<cnt;i++){
    country_name= jsonarr.getJSONObject(i).getString("name");
    country_rank= jsonarr.getJSONObject(i).getString("Rank");
}

tv.setText(country_rank.toString());

Hope this may help you!
