SQLite Select all rows and add to ListView Android

I want to add each row retrieved from database to the list view here's what I have done so far.

code from activity class

    private void getList() {
    list.add(dbms.selectAllFromRatings());
    arrayAdapter = new ArrayAdapter<String>(StationListView.this,
            android.R.layout.simple_list_item_1, list);
    listView.setAdapter(arrayAdapter);
}

// code from databaseHelper class

    public String selectAllFromRatings() {
    String selectAllQuery = " SELECT * FROM " + RATING_TABLE_NAME ;
            SQLiteDatabase sql = this.getReadableDatabase();
            Cursor c = sql.rawQuery(selectAllQuery, null);
        c.moveToFirst();
        return c.getString(c.getColumnIndex("stationName1"));
}
