You don't need to pass data to another ListView, only one ListView is needed to achieve what you desire. You will have to do the mapping yourself, i.e. BMW maps to a list(java.util.ArrayList) that contains all BMW car series models, and Mercedes maps to a list that contains all Mercedes car series models, etc.

When you select a car brand, you swap the underlying dataset for the ListView and call notifyDataSetChanged().

snippet:

MyAdapter myAdapter = ...;
Map<String, List<String>> carSeriesMap = ...;
protected void onListItemClick(ListView l, View v, int position, long id) {
    String brand = (String) getListAdapter().getItem(position);
    List<String> carSeriesList = carSeriesMap.get(brand);
    // set carSeriesList as the underlying dataset for the adapter
    myAdapter.setDataset(carSeriesList);
}

class MyAdapter extends BaseAdapter {
    List<String> dataset;
    public void setDataset (List<String> newDataset) {
        dataset = newDataset;
        notifyDataSetChanged();
    }
    public View getView(int position, ......) {
        // get data from dataset
        String text = dataset.get(position);
        // other code here...
    }
}
