通过URL建立连接 然后解析json

URL url = new URL(strUrl);             BufferedReader br = new BufferedReader(new InputStreamReader(url             .openStream(), "UTF-8"));             String s = "";             StringBuffer sb = new StringBuffer("");             while ((s = br.readLine()) != null) {                sb.append(s);

            }

picObj = new JSONObject(homePicContent);

String picData = picObj.getString("data");

for(int i=0;i<picSize;i++){                 JSONObject picJsonObj = picjsonArray.getJSONObject(i);                 HomePicDto homePicDto = new HomePicDto();                 homePicDto.setPicPath(picJsonObj.get("picPath").toString());                 homePicDto.setLink(picJsonObj.get("link").toString());                 homePicDtoList.add(homePicDto);             }
