Question

嗨我有一个列表，我从Json Feed中填写了一个标题，现在我想要添加一个图像继承我的single_list布局

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="?android:attr/listPreferredItemHeight"

    android:padding="6dip">

    <ImageView
        android:id="@+id/icon"
        android:layout_width="wrap_content"
        android:layout_height="fill_parent"
        android:layout_alignParentBottom="true"
        android:layout_alignParentTop="true" />

<TextView 
    android:orientation="vertical"
    android:layout_width="fill_parent"
        android:layout_height="wrap_content"
    android:background="@drawable/ic_gr_arrow"
    android:id="@+id/textView1" 
   android:textColor="@color/blue"
   android:padding="20dp"
   android:textSize="10dp" 

     />


</RelativeLayout>

继承人JSON Feed中的一个新闻故事的例子我觉得我需要image_small

{"code":200,"error":null,"data":{"news":[{"news_id":"8086","title":"Tickets for Player of the Year award on general sale","tagline":"Event to be held Sunday 25th March at Holiday Inn, Barnsley","content":"Tickets for the inaugural Evo-Stik NPL Player of the Year event are now on sale to the general public.\r\n\r\nPriced at \u00a335, tickets include a three course meal, plus entertainment from renowned tenor Martin Toal and guest speaker Fred Eyre.\r\n\r\nAwards at the event include the Player and Young Player of the Year for each division, as well as divisional teams of the year, the Fans\u2019 Player of the Year and a League Merit award.\r\n\r\nTo purchase your ticket, send a cheque for \u00a335 payable to \u201cNorthern Premier League\u201d to Alan Ogley, 21 Ibberson Avenue, Mapplewell, Barnsley, S75 6BJ.

并且到目前为止我的代码是

String json = reader.readLine();





            // Instantiate a JSON object from the request response
            JSONObject obj = new JSONObject(json);
            List<String> items = new ArrayList<String>();


            JSONObject objData = obj.getJSONObject("data");

            JSONArray jArray = objData.getJSONArray("news");


            for (int i=0; i < jArray.length(); i++)
            {    JSONObject oneObject = jArray.getJSONObject(i);
                items.add(oneObject.getString("title"));
                 Log.i("items", "items");
            }

            setListAdapter ( new ArrayAdapter<String>(this, R.layout.single_item, items));
            ListView list = getListView();
            list.setTextFilterEnabled(true);


            list.setOnItemClickListener(new OnItemClickListener(){

                public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
                        long arg3) {
                    // TODO Auto-generated method stub
                    Toast.makeText(getApplicationContext(), ((TextView) arg1).getText(),1000).show();
                }



            });


        } catch(Exception e){
            // In your production code handle any errors and catch the individual exceptions
            e.printStackTrace();
        }

我假设您要为listview中的每个项目加载Image，如果是这种情况，那么您可以从下面实现任何解决方案：

Android将Json Feed中的图像提供给列表
