I have a spinner(dynamic) which contains a list of IDs' and each ID has a product value. When I click on a particular ID, the value needs to be changed associated with that ID.

I have a listView which contains a table. The table consists of product names, product price and product information. When I change the ID, the table information(listview) changes but not the product value (this is a textview and not part of listview).

I'm passing the product value using an intent from a different class. How do I make it such that when I change an item in the spinner, the product value gets changed?

 /**
     * Listener for flight leg selection of spinner
     */
    private OnItemSelectedListener onFlightLegSelectedListener = new OnItemSelectedListener() {

        @Override
        public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
            new ShowSalesReportAsyncTask(flightLegMap.get(flightLegs.get(position)), position).executeOnExecutor(AsyncTask.THREAD_POOL_EXECUTOR);
        }

        @Override
        public void onNothingSelected(AdapterView<?> arg0) {
            // Do nothing
        }
    };

This is my onCreate where I am getting the product value.

   @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_sales_report);
        salesReportListView = (ListView) findViewById(R.id.sales_report_listview);
        spinnerFlightLegs = (Spinner) findViewById(R.id.flight_legs);
        noTransactionsWarning = (TextView) findViewById(R.id.no_transactions_warning);
        totalValueNetAmount = (TextView) findViewById(R.id.total_currency_net_value);
        String salesRevenue = TOTAL_VALUE;
        Bundle extras = getIntent().getExtras();
        if (extras != null) {
            salesRevenue = extras.getString(TOTAL_VALUE);
        }
        totalValueNetAmount.setText(salesRevenue);



        flightLegMap = getAllFlightLegs();
        if (!flightLegMap.isEmpty()) {
            setFlightLegSpinner();
            btnShare.setEnabled(true);
        } else {
            btnShare.setEnabled(false);
        }

        spinnerFlightLegs.setOnItemSelectedListener(onFlightLegSelectedListener);
        salesReportListAdapter = new SalesReportListAdapter(this);
        salesReportListView.setAdapter(salesReportListAdapter);

This is the Async task that I use to populate the view with data.

private class ShowSalesReportAsyncTask extends AsyncTask> {

private String flightLeg;
private int position;

public ShowSalesReportAsyncTask(String flightLeg, int position) {
    this.flightLeg = flightLeg;
    this.position = position;
}

@Override
protected List<Purchase> doInBackground(Void... params) {
    List<Purchase> rows = new ArrayList<Purchase>();
    PurchaseDao purchaseDao = new PurchaseDao(flightLeg, MIUtils.getShardDatabaseIndexMap());
    LOG.debug(TAG + "Getting report for : {}", flightLeg);
   // double netTotal = SalesUtil.calculateFlightTransactionTotal(purchaseDao, refundDao,());
    return purchaseDao.getSuccessfulTransactions();
}

@Override
protected void onPostExecute(List<Purchase> result) {
    super.onPostExecute(result);
    if (!result.isEmpty()) {
        noTransactionsWarning.setVisibility(View.GONE);
    } else {
        noTransactionsWarning.setVisibility(View.VISIBLE);
    }
    salesReportListAdapter.setRowsAndFlightDetails(result, flightLegMap.get(flightLegs.get(position)),
            spinnerFlightLegs.getSelectedItem().toString());

     totalValueNetAmount.setText((int) netTotal);

}

}

The item that needs to be changed is "EUR". SPINNER TABLE IMAGE

Add the code to register the listener in the onStart() method of the activity. This should work.

This should better answer your question - How to keep onItemSelected from firing off on a newly instantiated Spinner?
