log中能打出来字符，但最后的newsbean中显示为空。

Question

private List<NewsBean> getJsonDate(String url)

{

List<NewsBean> newsBeanlist = new ArrayList<NewsBean>();

try {

String jsonString = readStream(new java.net.URL(url).openStream());

// Log.i("log",jsonString);

JSONObject jsonObject;

NewsBean bean;

jsonObject = new JSONObject(jsonString);

JSONArray jsonArray = jsonObject.getJSONArray("data");

for(int i = 0; i<jsonArray.length(); i++)

{

jsonObject  = jsonArray.getJSONObject(i);

bean = new NewsBean();

bean.newsIconurl = jsonObject.getString("picSmall");

bean.newsTitle = jsonObject.getString("name");

bean.newsContent = jsonObject.getString("description");

newsBeanlist.add(bean);

}

} catch (MalformedURLException e) {

// TODO Auto-generated catch block

e.printStackTrace();

} catch (IOException e) {

// TODO Auto-generated catch block

e.printStackTrace();

} catch (JSONException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

return newsBeanlist;

}

Answer 1

newsBeanlist.add(bean);前增加个log，看程序有木有走到这，如果没有，说明json中没有数组。
