Spinner JSON Loading

I did have a look at spinners, but in the program that I am working on the data on the spinner is loaded from an API ... Being new, I sort of don't have any idea on loading the JSONObjects onto the spinner. Help please.

The API reply is sort of like this :

{"status":"","data":{"1":"scorpio"},"message":""}

Where I would have to display the value "Scorpio" the spinner and at the backend assign the value "1" while passing the form. Help please.

Put your JSON array into array and simple assign to spinners in loop:

//json array
{"Employee":[{"Id":73,"Name":"Bård Pedersen","Email":"[email protected]","Mobile":"9004422"}]}

ArrayList<String> TAG_ID = new ArrayList<String>();
ArrayList<String> TAG_NAME = new ArrayList<String>();
ArrayList<String> TAG_EMAIL = new ArrayList<String>();
ArrayList<String> TAG_PHONE_MOBILE = new ArrayList<String>();

  // Getting Array of Employee
        employee = json.getJSONArray("Employee");

        // looping through All Employee
        for (int i = 0; i < employee.length(); i++) {
            JSONObject c = employee.getJSONObject(i);

            // Storing each json item in variable
            id = c.getString("Id");
            name = c.getString("Name");
            email = c.getString("Email");
            mobile = c.getString("Mobile");

            // adding all get values into array
            if (name != "null" && mobile != "null") {
                TAG_NAME.add(name);
                TAG_ID.add(id);
                TAG_EMAIL.add(email);
                TAG_PHONE_MOBILE.add(mobile);
                close.add(R.drawable.close);
            }

If your data is in the following way

{"data":[{"1":"scorpio"},{"2":"BMW"},{"3":"Scoda"}]}

then you retrieve and show that in the spinner as follows:-

String[] id,name;

JSONObject jObject = new JSONObject(your data);
JSONObject jdata = jObject.getJSONArray("data");

id = new String[jdata.length()];
name = new String[jdata.length()];

Iterator<?> keys = jSEngineers.keys();

for(int i=0;i<jdata.length();i++){
id[i] = (String) keys.next();
name[i] = (String) jSEngineers.getString(id[i]);
}

Now you can get those values into the specified arrays.Now you can assign required one to Spinner.

ArrayAdapter<String> adapter = new ArrayAdapter<String>(YourActivity.this,android.R.layout.simple_spinner_item, name);
spinnerName.setAdapter(adapter);

now you can get selected spinner item as follows 

spinnerName.getSelectedItemPosition();

with this you will get the position of the item.with the help of that you can retrieve your required id that is for your background purpose.As follows..

Log.i("Item id is",id[spinnerName.getSelectedItemPosition()].toString());
