android控件listview的适配器方法

 public SimpleAdapter getSimpleAdapter(BillModel bm)
     {
         ArrayList<HashMap<String, Object>> listItem = new ArrayList<HashMap<String, Object>>();  
            for(int i=0;i<15;i++)  
            {  
                HashMap<String, Object> map = new HashMap<String, Object>();  
                map.put("ItemImage", R.drawable.icon);//图像资源的ID  
                map.put("ItemTitle", bm.getC_billno());  
                map.put("ItemText", bm.getC_billlx()+bm.getC_billbm());  
                listItem.add(map);  
            }  
            //生成适配器的Item和动态数组对应的元素  
            SimpleAdapter listItemAdapter = new SimpleAdapter(this,listItem,//数据源   
                R.layout.billlist,//ListItem的XML实现  
                //动态数组与ImageItem对应的子项          
                new String[] {"ItemImage","ItemTitle", "ItemText"},   
                //ImageItem的XML文件里面的一个ImageView,两个TextView ID  
                new int[] {R.id.ImageView01,R.id.Textbillno,R.id.TextDetail}  
            );  
            return listItemAdapter;
     }
