如何从游标填充的游标中获取值

Question

I've populated my spinner as this:

DatabaseConnector dbConnector = new DatabaseConnector(this);
    dbConnector.open();
    Cursor c = dbConnector.raw("SELECT _id, nombrecasa FROM casa");
    startManagingCursor(c);
    String[] from = new String[]{"nombrecasa"};
    int[] to = new int[]{android.R.id.text1};
    SimpleCursorAdapter adapter =
    new SimpleCursorAdapter(this, android.R.layout.simple_spinner_item, c, from, to );
    adapter.setDropDownViewResource( android.R.layout.simple_spinner_dropdown_item );
    casaSpinner = (Spinner) findViewById( R.id.casaspinner);
    casaSpinner.setAdapter(adapter);
    dbConnector.close();
    }

And when I try to get the value as:

String idcasa   = casaSpinner.getSelectedItem().toString();

it only returns this:

android.database.sqlite.SQLiteCursor@40539880

Answer 1

Your spinner has taken a SimpleCursorAdapter as an adapter, of which its dataset is a Cursor . When you select an item on the spinner, you've only moved the cursor to a specific row and when you call getSelectedItem() you're still requesting for the dataset object - which is still a cursor object. to do what you're trying you can simply call:

c.getString(1);

once your selection has been made. For something a little more fundamentary illustrative of what i said.

((Cursor) casaSpinner.getSelectedItem()).getString(1);
