android listview适配器引发异常

我为包含图像、文本视图和文本框的listview_项构建了一个适配器，我不知道为什么应用程序会抛出异常

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;

    }
}

它仍然抛出异常

如果你想要其他代码，我会给你的

谢谢

新的例外 我想

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

---

如果

vi==null

则必须将充气机设置为

vi

。否则，您将尝试从零或

null

比如说

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

---

发布LogCat以便我们可以帮助解决哪个异常？我在你的帖子中看不到任何内容…非常感谢，+1代表你，我接受Mistsuaki的回答，因为他先回答我，同样的例外？如果没有发布新的one@tyczjj我发布了一个新的例外，即值

restaurant

为null（但如果它通过

restaurant.get（“name”）

它可能不是），或者“image”的数据为null或不正确，很难从给出的内容中分辨出来，在那里设置一个断点，在将图像值传递到

ImageView

之前查看图像值。您可以访问窗口中的所有视图>显示视图并选择您想要的视图。它可以正常工作，但当我尝试滚动项目时，我遇到了一个异常，为什么？请告诉我您的堆栈跟踪？（例外）谢谢！您能给我看看Select_Multi_Restaurants.java的第133行吗？没有133行：），它只是119行，可能与您的问题无关。*如果vi（=convertView）不是null…，会发生什么情况？*每次分配每个列表项数据时，都会调用findViewById。这不是更快的ListView。查看以下URL？（'ω｀）

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

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