Question

I am stuck with SimpleCursorAdapter, I am calling my local SQLite DB and putting it into a cursor which then is passed to the SimpleCursorAdapter.

For same reason the Log Cat keeps showing this error below. I have no idea what is going on and I have been working on this for 6 hours, I didn’t think SimpleCursorAdapter would be so difficult to understand.

05-28 19:47:27.524: ERROR/AndroidRuntime(9353): java.lang.RuntimeException: Unable to start activity ComponentInfo{com.nyneaxis.android.mpg/com.nyneaxis.android.mpg.userInfo}: java.lang.IllegalArgumentException: column '_id' does not exist


        setArray();
    rec.open();
        Cursor c = rec.getAllVeh();
        SimpleCursorAdapter adapter = new SimpleCursorAdapter(this, R.layout.userinfo, c, new String[]{c.getString(1)}, new int[]{R.id.nameTxtL});
        this.setListAdapter(adapter);
    rec.close();

//data adapter

public Cursor getAllVeh() {
    try{
    return db.query(database_table, new String[] { key_rowid, vehicle_name,
            year, make, model, style, vin, plate, notes }, null, null,
            null, null, null);
    }finally{

    }
}

Okay I have modified my code to a rawQuery and I get this error again:

05-28 22:41:48.876: ERROR/AndroidRuntime(1359): java.lang.RuntimeException: Unable to start activity ComponentInfo{com.nyneaxis.android.mpg/com.nyneaxis.android.mpg.userInfo}: android.database.CursorIndexOutOfBoundsException: Index -1 requested, with a size of 0

private static final String db_sel = "SELECT id as _id, vehicle_name FROM vehicle";

public Cursor getAllVeh() {
        try{
            return db.rawQuery(db_sel, null);
        /*return db.query(database_table, new String[] { key_rowid, vehicle_name,
                year, make, model, style, vin, plate, notes }, null, null,
                null, null, null);*/
        }finally{

        }
    }

Thanks guys for all you help. I managed to do it a different way and it seems to work like a charm. If anyone has any question or suggestions let me know.

Cursor c = rec.getAllVeh();

while (c.moveToNext()) {
String vehName = c.getString(1);
vehInfo.add(vehName);
}

//put information into the addapter for listview
adapter = new ArrayAdapter<String>(this,
    android.R.layout.simple_list_item_single_choice, vehInfo);

//applies adapter to listview
list.setAdapter(adapter);
