Question

I’m developing an Android application with a spinner.

I have this problem:

This is spinner array adapter code:

public class OrderArticlesAdaper extends ArrayAdapter<Article>
{
    private Context mContext;
    private int layoutResourceId;
    private ArrayList<Article> articles;

    public OrderArticlesAdaper(Context context, int listItemResourceId,
            ArrayList<Article> dbArticles)
    {
        super(context, listItemResourceId, dbArticles);

        this.mContext = context;
        this.layoutResourceId = listItemResourceId;
        this.articles = dbArticles;
    }

    public ArrayList<Article> getArticles()
    {
        return this.articles;
    }

    @Override
    public int getCount()
    {
        return articles.size();
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent)
    {
        Log.v("OrderArticlesAdaper", "getView.postion: " + position);
        View row = convertView;
        if (row == null)
        {
            LayoutInflater inflater = ((Activity)mContext).getLayoutInflater();
            row = inflater.inflate(layoutResourceId, parent, false);
        }

        Article article = articles.get(position);
        if (article != null)
        {
            TextView formNameView = (TextView)row.findViewById(android.R.id.text1);
            formNameView.setText(new Long(article.getArticleId()).toString());
        }
        return row;
    }
}

And this is an asynctask to load spinner data:

private class LoadEReportAsyncTask extends AsyncTask<String, Void, Boolean>
{
    private Context mContext;
    private ProgressDialog loadingDialog;
    private EReport eReport;
    private QAP qap;

    public LoadEReportAsyncTask(Context context)
    {
        Log.v("LoadEReportAsyncTask", "constructor");
        eReport = null;
        qap = null;

        this.mContext = context;
        loadingDialog = new ProgressDialog(mContext);
        loadingDialog.setProgressStyle(ProgressDialog.STYLE_SPINNER);
        loadingDialog.setMessage(getString(R.string.msg_loading_ereport));
        loadingDialog.setCancelable(false);
        loadingDialog.show();
    }

    @Override
    protected Boolean doInBackground(String... params)
    {
        Log.v("LoadEReportAsyncTask", "doInBackground");
        DBManager dbMan;
        dbMan = new DBManager(mContext);

        // Es un nuevo EReport, por lo tanto lo creo en la base de datos.
        if (eReportId == -1)
        {
            // Time In
            TextView aux = (TextView)((EReportFinalInspecActivity) mContext).findViewById(R.id.timeInVal);

            Calendar c = Calendar.getInstance();
            SimpleDateFormat df3 = new SimpleDateFormat("dd-MM-yyyy HH:mm:ss");
            String timeIn = df3.format(c.getTime());
            aux.setText(timeIn);

            eReport = new EReport();
            eReport.setOrderId(orderId);
            eReport.setQapId(qapId);
            eReport.setTimeIn(timeIn);

            eReportId = dbMan.insertEReport(eReport);
        }
        else
        {
            eReport = dbMan.getEReport(eReportId);
        }

        qap = dbMan.getQPA(params[0]);
        ordersArticles = dbMan.getOrderArticles(orderId);

        selectedArticles = new ArrayList<Article>(ordersArticles.size());

        return true; // TODO: Controlar los errores
    }

    protected void onPostExecute(Boolean result)
    {
        Log.v("LoadEReportAsyncTask", "onPostExecute");

        EReportFinalInspecActivity act = (EReportFinalInspecActivity) mContext;
        if (result)
        {
            Toast.makeText(getApplicationContext(), getString(R.string.msg_ereport_got_correct), Toast.LENGTH_SHORT).show();

            act.fillEReport(eReport, qap);
            Spinner articleSpin = (Spinner) act.findViewById(R.id.articlesSpiner);
            OrderArticlesAdaper spinAdapter = new OrderArticlesAdaper(mContext, android.R.layout.simple_spinner_item, ordersArticles);
            spinAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
            articleSpin.setAdapter(spinAdapter);

            // TODO: Esto hay que cambiarlo porque siempre habrá QAP.
            if (qap != null)
                act.eReportHasQAP(true, qap.getName());
            else
                act.eReportHasQAP(false, null);
        }
        else
        {
            Toast.makeText(getApplicationContext(), getString(R.string.msg_ereport_problem), Toast.LENGTH_LONG).show();
        }

        loadingDialog.dismiss();
    }
}

What am I doing wrong?

Answer 1

Try:

formNameView.setText(Long.toString(article.getArticleId()));

Edit:

This is just a guess, but maybe Android is filling the spinner dropdown textviews using Article.toString(), since your adapter handles objects of type Article.

To test this, override toString in your Article class.

public class Article {
    ...
    @Override
    public String toString() {
        mArticleId.toString(); // This is the private field holding the long id.
    }
}
