Recover Spinner’s position to use in another Spinner from another Acitivity

Question

I have a Banknote Registration App that has 1 spinner. Spinner contains card registration with Idcard, title and description (Saved in a "Card" table in the database). When save this register from Notes in the "Notes" table, only the Idcard is saved from this spinner.

I have another Activity that edits this register of Notes, it has the same spinner, but I want that spinner is already in the position of the item to be edited, but not being able to do it, someone has some solution?

Note: Do you have how to get the position of the item from the Idcard?

Thank you in advance.

Letter from.java.:

public class CartaoDao extends Dao {

    private static final String TABELA = "cartao";
    public static final String IDCARTAO = "idcartao";
    public static final String DESCARTAO = "descartao";
    public static final String NUMBERCARD = "numbercard";

    public CartaoDao(Context context) {
        super(context);
    }

    public ArrayList<HMAuxCartao> obterListaCartao() {
        ArrayList<HMAuxCartao> cartao = new ArrayList<>();
        //
        abrirBanco();
        //
        Cursor cursor = null;
        //
        try {
            String comando = " select " + IDCARTAO + ", " + DESCARTAO + ", " + NUMBERCARD  + " from " + TABELA + " order by " + DESCARTAO + " ";
            //
            cursor = db.rawQuery(comando, null);
            //
            while (cursor.moveToNext()) {
                HMAuxCartao hmAux = new HMAuxCartao();

                hmAux.put(IDCARTAO, cursor.getString(cursor.getColumnIndex(IDCARTAO)));
                hmAux.put(DESCARTAO, cursor.getString(cursor.getColumnIndex(DESCARTAO)));
                hmAux.put(NUMBERCARD, cursor.getString(cursor.getColumnIndex(NUMBERCARD)));
                //
                cartao.add(hmAux);
            }
            //
            cursor.close();

        } catch (Exception e) {
            Log.e(TAG, "obterListaCartao: ");
        }
        //
        fecharBanco();
        //
        return cartao;
    }
}

To complete the code have the Models, if need I put here. I put only the essential code.

Answer 1

Try to get the position of the item as follows:

sp_card.setSelection(sp_card.getAdapter().indexOf(String.valueOf(idCartao)));

Answer 2

In Notaseditactivity.java I changed the method getSpinnerIndex for:

public int getSpinnerIndex(Spinner spinner, String myString) {
    int index = 0;

    for (int i = 0; i < spinner.getCount(); i++) {
        HMAuxCartao model = hmAux.get(i);
        String modelS = model.get(CartaoDao.IDCARTAO);
        if (modelS != null) {
            if (modelS.equals(myString)) {
                index = i;
            }
        }
    }
    return index;
}

in the same Activity where has the action of Spinner I deleted everything and just added:

        hmAux = cartaoDao.obterListaCartao();
        sp_card.setSelection(getSpinnerIndex(sp_card, String.valueOf(idCartao)));

This hmAux being the type ArrayList<HMAuxCartao>.

I appreciate the help.
