Update a field in a listview - Android

Question

I have a ListView and a spinner and when I want select from the spinner, I want to update one field for every item in the ListView with the selected value from the spinner. I have a CustomAdapter which extends CursorAdapter. How can I do that exactly?

Code for CustomCursorAdapterProdus2:

public class CustomCursorAdapterProdus2 extends CursorAdapter {

private static final String TAG = null;
Context con;
public CustomCursorAdapterProdus2(Context context, Cursor c) {
    super(context, c);
    con = context;
}

@Override
public View newView(Context context, Cursor cursor, ViewGroup parent) {
    LayoutInflater inflater = LayoutInflater.from(parent.getContext());
    View retView = inflater.inflate(R.layout.single_row_item_produsefactura, parent, false);
    return retView;
}

@Override
public void bindView(View view, Context context, Cursor cursor) {
    TextView textViewId = (TextView) view.findViewById(R.id.denumire);
    textViewId.setText(cursor.getString(cursor.getColumnIndex(cursor.getColumnName(1))));
    TextView textId = (TextView) view.findViewById(R.id.id_produsFact);
    textId.setText(cursor.getString(cursor.getColumnIndex(cursor.getColumnName(0))));
    TextView textUm = (TextView) view.findViewById(R.id.unitateMasura);
    textUm.setText(" (" + cursor.getString(cursor.getColumnIndex(cursor.getColumnName(4))) + ")");
    }
}

This is the code for single_row_item_produsefactura.xml which fills the listview:

<?xml version="1.0" encoding="utf-8"?>

You can use setAdapter() method after every click. It will reload the whole list. — Faruk Yazici, Sep 30 '14 at 13:29
You should google before writing here a question. Check [this link](http://stackoverflow.com/questions/4198425/updating-the-list-view-when-the-adapter-data-changes) — Batuhan Coşkun, Sep 30 '14 at 13:32
Thank you! I am not a pro in Android, but I hope I will understand. — Silviu Pal, Sep 30 '14 at 13:39
