Question

I have a simple Spinner implemented as:

vehicle = json.getJSONArray("vehicle");
for(int i = 0; i < vehicle.length(); i++){
    JSONObject c = vehicle.getJSONObject(i);
    //put json obkject on variable
    String id = c.getString("id");
    String name = c.getString("name");
    String capacity = c.getString("capacity");
    String cost = c.getString("cost");
    String v = name + " ("+capacity + " Liters)";
    vehicleList.add(v);
    // Set Spinner Adapter
    mySpinner.setAdapter(new ArrayAdapter<String>(OrderDetails.this,android.R.layout.simple_spinner_dropdown_item,vehicleList));
    // Spinner on item click listener
    mySpinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
        @Override
        public void onItemSelected(AdapterView<?> arg0,View arg1, int position, long arg3) {  
            car = vehicleList.get(+position); 
            Toast.makeText(getApplicationContext(), car, Toast.LENGTH_SHORT).show();
        }

        @Override
        public void onNothingSelected(AdapterView<?> arg0) {
            car = null;
        }
    });                     
}  

I wanted to grab the value of "ID" in the car variable. Is it possible with above implementation?

Thanks in advance.

La solution

try to replace your item click listener with this ...

mySpinner.setOnItemSelectedListener(new OnItemSelectedListener() {

    public void onItemSelected(AdapterView<?> arg0, View view,
            int position, long id) {
        int spinnerItem = spinner.getSelectedItemPosition();
        car = vehicleList.get(spinnerItem);
        Toast.makeText(getApplicationContext(), selectedId, Toast.LENGTH_SHORT).show();     
    }

    public void onNothingSelected(AdapterView<?> arg0) {
        // nothing to do here :|
    }
});

//EDIT you can create another list that hold values of IDs ... and then add values to it as vehicleList ...

idList.add(id);

and then just call when item is selected in spinner

String selectedId = idList.get(spinnerItem);

Returns the position selected.

  mySpinner.getSelectedItem() 

or

mySpinner.getSelectedItemPosition()
