1:URL url = new URL("http://www.sohu.com/");
2:HttpURLConnection conn = (HttpURLConnection)url.openConnection();
3:参数设定;
conn.setRequestMethod("GET");
conn.setConnectTimeout(5 * 1000);
设置位图:
Bitmap bitmap = BitmapFactory.decodeByArray(byte[],0,length);
imageView.setImageBitmap(bitmap);
JSON(org.json)
JSONArray json = new JSONArray(String);
Json.getId(); à>json.getString();à>json.getLong();
网络数据提交:
HttpRequest.sendGetRequest(*******);
S数据编码:URLEncoder.eccode();
使用手机上传数据的时候要对数据进行编码:
Conn.setRequestMethod(“POST”);
Conn.setRequestTimeout(1000);
Conn.setDoOutput(ture);//准许对出输出数据
Conn.setRequestProperty(“application/x-www-form-urlencoded”);
Conn.setRequestProperty(“Content-Length”,String.valueOf(entitydata.length));
得到服务器路径:
Request.getSession().getServletContext().getRealPath(“/video”);
Android对json的处理;
内置对象JSONArray array = new JSONArray(String);
JSONObject item = array.getJSONObject(i);
Item.get(“key”);
