Set selected spinner item value to Edit Text View - Android

Question

I am new to android. I am displaying strings in my spinner and when user selects a string, i want to enter selected spinner string value using edit text view(when user select food item from spinner i want to enter food's value 10 using edit text view). I am done with setting up the spinner items but i don't know how to enter selected spinner value.

this is my java file,

public class PaymentsActivity extends Activity implements OnItemSelectedListener {

private Button btnViewExpenses;
private Spinner spinner;
private EditText selectedSpinner;
// array list for spinner adapter
private ArrayList<Category> categoriesList;
ProgressDialog pDialog;

// API urls
// Url to get all categories
private String URL_CATEGORIES = "http://10.0.2.2/category_api/get_categories.php";

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.payments);

    selectedSpinner = (EditText) findViewById(R.id.categoryItem);
    spinner = (Spinner) findViewById(R.id.categoryList);
    btnViewExpenses = (Button) findViewById(R.id.btnViewExpenses);

    categoriesList = new ArrayList<Category>();

    // spinner item select listener
    spinner.setOnItemSelectedListener(this);

    new GetCategories().execute();

}

/**
 * Adding spinner data
 * */
private void populateSpinner() {
    List<String> lables = new ArrayList<String>();

//  txtCategory.setText("");

    for (int i = 0; i < categoriesList.size(); i++) {
        lables.add(categoriesList.get(i).getName());
    }

    // Creating adapter for spinner
    ArrayAdapter<String> spinnerAdapter = new ArrayAdapter<String>(this,
            android.R.layout.simple_spinner_item, lables);

    // Drop down layout style - list view with radio button
    spinnerAdapter
            .setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);

    // attaching data adapter to spinner
    spinner.setAdapter(spinnerAdapter);
}

/**
 * Async task to get all categories
 * */
private class GetCategories extends AsyncTask<Void, Void, Void> {

    @Override
    protected void onPreExecute() {
        super.onPreExecute();
        pDialog = new ProgressDialog(PaymentsActivity.this);
        pDialog.setMessage("Loading Expenses Information...");
        pDialog.setCancelable(false);
        pDialog.show();

    }

    @Override
    protected Void doInBackground(Void... arg0) {
        ServiceHandler jsonParser = new ServiceHandler();
        String json = jsonParser.makeServiceCall(URL_CATEGORIES, ServiceHandler.GET);

        Log.e("Response: ", "> " + json);

        if (json != null) {
            try {
                JSONObject jsonObj = new JSONObject(json);
                if (jsonObj != null) {
                    JSONArray categories = jsonObj
                            .getJSONArray("categories");                        

                    for (int i = 0; i < categories.length(); i++) {
                        JSONObject catObj = (JSONObject) categories.get(i);
                        Category cat = new Category(catObj.getInt("id"),
                                catObj.getString("category"));
                        categoriesList.add(cat);
                    }
                }

            } catch (JSONException e) {
                e.printStackTrace();
            }

        } else {
            Log.e("JSON Data", "Didn't receive any data from server!");
        }

        return null;
    }

    @Override
    protected void onPostExecute(Void result) {
        super.onPostExecute(result);
        if (pDialog.isShowing())
            pDialog.dismiss();
        populateSpinner();
    }

}


@Override
public void onItemSelected(AdapterView<?> parent, View view, int position,
        long id) {
    Toast.makeText(
            getApplicationContext(),
                    parent.getItemAtPosition(position).toString() + " Selected" ,
            Toast.LENGTH_LONG).show();

}

@Override
public void onNothingSelected(AdapterView<?> arg0) {        
}

public void onClickViewExpenses(View view){
    Intent viewExpenses = new Intent(this, ExpensesList.class);
    startActivity(viewExpenses);
}
}

Use this.

@Override
public void onItemSelected(AdapterView<?> parent, View view, int position,
    long id) {

   String myStr = spinner.getSelectedItem().toString();
   selectedSpinner.setText(myStr);

}

@Override
public void onNothingSelected(AdapterView<?> arg0) {        
}
