java - MultiList 不显示来自 Web 服务的所有结果(代号一)

Question

我正在尝试使用 MultiList 显示一些 json 记录。我按照这里所做的https://www.codenameone.com/manual/graphics.html进行操作但我的只返回一条记录(请参阅此 image )。响应来自此webservice

下面是我的代码。请告诉我哪里错了。

@Override
    protected void beforeFormA(Form f) {        
         Style s = UIManager.getInstance().getComponentStyle("Button");
         FontImage p = FontImage.createMaterial(FontImage.MATERIAL_PORTRAIT, s);
         EncodedImage placeholder = EncodedImage.createFromImage(p.scaled(p.getWidth() * 3, p.getHeight() * 4), false);
         getattractive();//fetch results from webservice and store inside response variable
         ArrayList arr = (ArrayList) response.get("results");                
                for (Object m:arr){                   
                Map ma = (Map)m;                        
                address =(String) ma.get("formatted_address");
                name=(String)ma.get("name");
                icon=(String)ma.get("icon");
         ArrayList<Map<String, Object>> data = new ArrayList<>(); 
         data.add(createListEntry(name,address,icon));                                      
        DefaultListModel<Map<String, Object>> model = new DefaultListModel<>(data);
        MultiList ml = new MultiList(model);
        ml.getUnselectedButton().setIconName("icon_URLImage");
        ml.getSelectedButton().setIconName("icon_URLImage");
        ml.getUnselectedButton().setIcon(placeholder);
        ml.getSelectedButton().setIcon(placeholder);
        f.add(BorderLayout.CENTER, ml);          
      }                    
   }    


private Map<String, Object> createListEntry(String name, String addr, String coverURL) {
    Map<String, Object> entry = new HashMap<>();    
    entry.put("Line1", name);
    entry.put("Line2", addr);
    entry.put("icon_URLImage", coverURL);
    entry.put("icon_URLImageName", name);
    return entry;

您应该修复缩进。 for 循环封装了所有内容，因此您可以循环遍历所有元素，并且对于 X 个元素，您可以添加 X 个多重列表。

如果您使用调试器单步执行代码，您会立即看到这一点...
