i build an adapter for a listview_item which contains image, textview and textbox, i don’t know why the application throw an exception,

class RestaurantAdapter extends BaseAdapter {
    private static LayoutInflater inflater = null;
    private ArrayList<HashMap<String, String>> data;
    Activity activity;

    public RestaurantAdapter(Activity activity,
            ArrayList<HashMap<String, String>> data) {
        // TODO Auto-generated constructor stub
        this.activity = activity;
        this.data = data;
        inflater = (LayoutInflater) activity
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    }

    @Override
    public int getCount() {
        // TODO Auto-generated method stub
        return data.size();
    }

    @Override
    public Object getItem(int position) {
        // TODO Auto-generated method stub
        return position;
    }

    @Override
    public long getItemId(int position) {
        // TODO Auto-generated method stub
        return position;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        // TODO Auto-generated method stub
        View vi = convertView;
        if (vi == null)
            inflater.inflate(R.layout.restaurant_multi_select_list_item, null);
         TextView name = (TextView) vi
                .findViewById(R.id.restaurant_multi_select_title);
        ImageView image = (ImageView) vi
                .findViewById(R.id.restaurant_multi_select_list_item_image);
        CheckBox cb = (CheckBox) vi
                .findViewById(R.id.restaurant_multi_select_checkBox);
        HashMap<String, String> restaurant = data.get(position);
        name.setText(restaurant.get("name"));
        cb.setSelected(false);
        image.setId(Integer.parseInt(restaurant.get("image")));
        return vi;

    }
}

when i made the getview contains just this code

View vi = convertView;
            if (vi == null)
                inflater.inflate(R.layout.restaurant_multi_select_list_item, null);

it still throws the exception

if you want any another code i will give it to you

thanks

if vi == null then you have to set the inflater to vi. otherwise you are trying to get a view from nothing or null

for example

if (vi == null)
       vi = inflater.inflate(R.layout.restaurant_multi_select_list_item, null);
